CENTRIFUGAL PUMPS IN THE CHEMICAL INDUSTRY Abstract : A centrifugal pump converts the input power to kinetic energy in the liquid by accelerating the liquid by a revolving device - an impeller. The most common type is the volute pump. Fluid enters thepump through the eye of the impeller which rotates at high speed. The fluid is accelerated radially outwardfrom the pump chasing. A vacuum is created at the impellers eye that continuously draws more fluid into the pump . This article stresses on a series of centrifugal pumps，From a brief introduction to the principles.Keywords: centrifugal pump ,Introduction ,Working principle , Cavitation ，Mechanism of Cavitation ，Solution and Remedies1. IntroductionPump ,device used to raise ,transfer ,or compress liquids and gases .Four general classes of pumps for liquids are described below .In all of them ,steps are taken to prevent cavitation (the formation of a vacuum) ,which would reduce the flow and damage the structure of the pump .Pumps used for gases and vapors are usually known as compressors .The study of fluids in motion is called fluid dynamics.Water pump ,device for moving water from one location to another ,using tubes or othermachinery .Water pumps operate under pressures ranging from a fraction of a pound to more than 10,000 pounds per square inch .Everyday examples of water pumps range from small electric pumps that circulate and aerate water in aquariums and fountains to sump pumps that remove water from beneath the foundations of homes .One type of modern pumps used to move water is the centrifugal pump .Early version of the centrifugal pump ,the screw pump ,consists of a corkscrew-shaped mechanism in a pipe that ,when rotated ,pulls water upward .Screw pumps are often used in waste-water treatment plants because they can move large amounts of water without becoming clogged with debris .In the ancient Middle East the need for irrigation of farmland was a strong inducement to develop a water pump .Early pumps in this region were simple devices for lifting buckets of water from a source to a container or a trench .Greek mathematician and inventor Archimedes is thought to have devised the first screw pump in the third century BC .Later Greek inventor Ctesibius develop the first lift pump .During the late 17th and early 18th Centuries AD ,British engineer Thomas Savery ,French physicist Denis Papin ,And British blacksmith and inventor Thomas Newcomen contributed to the development of a water pump that used steam to power the pump’ piston .The steam-powered water pump’s first wide use was in pumping water out of mines .Modern-day examples of centrifugal pumps are those used at the Grand Coulee Dam on the Columbia River .This pump system has the potential to irrigate over one million acres of land .Also known as rotary pumps ,centrifugal pumps have a rotating impeller ,also known as a blade ,that is immersed in the liquid .Liquid enters the pump near the axis of the impeller ,and the rotating impeller sweeps the liquid out toward the ends of the impeller blades at high pressure .The impeller also gives the liquid a relatively high velocity that can be converted into pressure in a stationary part of the pump ,known as the diffuser .In high-pressure pumps ,a number of impeller may be used in series ,and the diffusers following each impeller may contain guide vanes to gradually reduce the liquid velocity .For lower-pressure pumps ,the diffuser is generally a spiral passage ,known as a volute ,with its cross-sectional area increasing gradually to reduce the velocity efficiently .The impeller must be primed before it can begin operation ,that is ,the impeller must be surrounded by liquid when the pump is started .This can be done by placing a check valve in the suction line ,which holds the liquid in the pump when the impeller is not rotating .If this valve leaks ,the pump may need to be primed by the introduction of liquid from an outside source such as the discharge reservoir .A centrifugal pump generally has a valve in the discharge line to control the flow andpressure .For low flows and high pressures ,the action of the impeller is largely radial .For higher flows and lower discharge pressure ,the direction of the flow within the pump is more nearly parallel to the axis of the shaft ,and the pump is said to have an axial flow .The impeller in this case acts as a propeller .The transition from one set of floe conditions to the other is gradual ,and for intermediate condition , the device is called a mixed-flow pump .2.The Centrifugal PumpThe centrifugal pump is by far the most widely used type in the chemical and petroleum industries .It will pump liquids with very wide ranging properties and suspensions with a high solids contentincluding ,for example ,cement slurries ,and may be constructed from a very wide rang of corrosion resistant materials .The whole pump casing may be constructed from plastic such as polypropylene or it may be fitted with a corrosion-resistant lining .Because it operates at high speed ,it may be directly coupled to an electric motor and it will give a high flow rate for its size .In this type of pump ,the fluid is fed to the centre of a rotating impeller and is thrown outward by centrifugal action .As a result of the high speed of rotation the liquid acquires a high kinetic energy and the pressure difference between the suction and delivery sides arises from the conversion of kinetic energy into pressure energy .The impeller consists of a series of curved vanes so shaped that the flow within the pump is as smooth as possible .The greater the number of vanes on the impeller ,the greater is the control over the direction of the liquid and hence the smaller are the losses due to turbulence and circulation between the vanes .In the open impeller ,the vanes are fixed to a central hub ,whereas in the closed type the vanes are held between two supporting plates and leakage across the impeller is reduced .As will be seen later ,the angle of the tips of the blades very largely determines the operating characteristics of the pump .The liquid enters the casing of the pump，normally in an axial direction，and is picked up by the vanes of the impeller．In the simple type of centrifugal pump，the liquid discharges into a volute，a chamber of gradually increasing cross—section with a tangential outlet．A volute type of pump is shown in Fig.(a)．In the turbine pump[-Fig．(b)]the liquid flows from the moving vanes of the impeller through a series of fixed vanes forming a diffusion ring．This gives a more gradual change in direction to the fluid and more efficient conversion of kinetic energy into pressure energy than is obtained with the volute type．The angle of the leading edge of the fixed vanes should be such that the fluid is received without shock．The liquids flows along the surface of the impeller vane with a certain velocity whilst the tip of the vane is moving relative to the casing of the pump．The direction of motion of the liquid relative to the pump casing--and the required angle of the fixed vanes—is found by compounding these two velocities．In Fig．c，c.is the velocity of the liquid relative to the vane and is the tangential velocity of the tip of the vane ；vu t u compounding these two velocities gives the resultant velocity of the liquid ．It is apparent ，therefore ，2u that the required vane angle in the diffuser is dependent on the throughput ，the speed of rotation ，and the angle of the impeller blades ．The pump will therefore operate at maximum efficiency only over a narrow range of conditions ．Virtual head of a centrifugal pumpThe maximum pressure is developed when the whole of the excess kinetic energy of the fluid isconverted into pressure energy. As indicated below ．the head is proportional to the square of the radius and to the speed ，and is of the order of 60m for a single—stage centrifugal pump ；for higher pressures ，multistage pumps must be used ．Consider the liquid which is rotating at a distance of between r and r+dr from the centre of the pump(Fig ．d)．dThe mass of this element of fluid dm is given by 2πrdrdρ，where ρ is the density of the fluid and 6 is the width of the element of fluid 。

外文翻译--泵的概述
外文原文：Pump's outlineThe pump is the application very widespread general machinery, may say that is place of the fluid flow, nearly has the pump in the work. Moreover, along with science's and technology's development, pump's application domain is expanding rapidly, according to the over-all state statistics, pump's power consumption approximately composes the national total output of electrical energy 1/5, obviously the pump is natural consumes energy the wealthy and powerful family. Therefore, raises the pump technical level to save the energy consumption to have the important meaning.First. Centrifugal pump's principle of workThe drive leads impeller revolving through the pump spindle to have the centrifugal force, under the centrifugal action of force, the liquid is flung along the leaf blade flow channel to the impeller export, the liquid sends in after the volute collection the eduction tube. The liquid obtains the energy from the impeller, • causes the pressure energy and the speed can increase, and depends upon this energy the hydraulic transport to the operating location. while the liquid is flung which exports to the impeller, the impeller eye center has formed the low pressure, • has had the differential pressure in the imbibition pot and between the impeller center liquid, in the imbibition pot's liquid under this differential pressure function, after inhales the pipeline and pump's suction chamber unceasingly enters in the impeller.Second, centrifugal pump's structure and main spare partA centrifugal pump mainly by the pump body, the impeller, the packing ring, the rotation axis, the axis seals parts and so on box to be composed, some centrifugal pumps are also loaded with the guide pulley, the inducer, the balance disc and so on.1. Pump body: Namely pump's shell, including suction chamber and delivery chamber.①Suction chamber: Its function is enables the liquid to flow in evenly the impeller.②Delivery chamber: Its function collects the liquid, and sends in it the subordinate impeller or guides the eduction tube, at the same time reduces the liquid the speed, causes the kinetic energy to further turn the pressure energy. The delivery chamber has the volute and the guide vane two forms.2. Impeller: It is in the centrifugal pump transmits the energy for the liquid only part, the impeller with the bond fixation on the axis, leads revolving alongwith the axis by the prime mover, passes to through the leaf blade prime mover's energy the liquid.Impeller classification:①According to liquid inflow classification: Single suction impeller (in impeller's one side has an entrance) and double attracts the impeller (liquid from impeller's lateral symmetry liudao impeller passage).②Is opposite according to the liquid in centerline's flow direction classification: Runoff type impeller, axial-flow propeller and interflow type impeller.③According to impeller's structural style classification: Shrouded impeller, open type impeller and semi-opened impeller.3. Axis: Is transmits the mechanical energy the important components, the • prime mover's torque passes to the impeller through it. The pump spindle is the pump rotor's major parts, on the axis is loaded with components and so on impeller, axle sleeve, balance disc. The pump spindle depending on the both sides bearing supporting, makes the high speed rotation in the pump, thus the pump spindle in a big way wants the bearing capacity, to be wear-resisting, to be anti-corrosive. Pump spindle's material selects the carbon steel or the alloy steel and after the quenching and retempering treatment generally.4. Packing ring: Is installs in the rotation impeller and the static pump housing (center-section and guide vane's assembly) between packing assembly. It is function is through controls between the two gap method, increases in the pump between the high and low pressure cavity the fluid flow resistance, reduces divulging.5. Axle sleeve: The axle sleeve is uses for to protect the pump spindle, causes it not to corrode and the attrition. When necessity, the axle sleeve may replace.6. Axis seals: The pump spindle and around packing box between end cover's installs short for axis to seal, mainly prevents in pump's liquid divulging and the air enters in the pump, achieves seals and prevents the air admission to cause the pump cavitation goal. the axis seals form: Namely has skeleton's rubber seal, the packing seal and the mechanical seal.7. axial force balancing unit.Third. Centrifugal pump's prime task parameter1. Current capacity: Namely the pump in unit of time discharges the liquid quantity, usually indicated with the Unit of volume that mark Q, the unit has m3/h, m3/s, l/s and so on,2. Lifting: The transportation unit weight's liquid (pump suction flange) (pump discharge flange) from the pump inlet place to the pump exit, its energy's increment, indicated with H, the unit is m.3. Rotational speed: Pump's rotational speed is the pump each minute revolving number of times, expressed with N. Electrical machinery rotational speed •N generally about 2900 n/min.4. Net positive suction head: Centrifugal pump's net positive suction head isNPSH • uses the expressed that pump's performance's main parameter,rsymbolic representation.5. Power and efficiency: Pump's power input is shaft power P, is also electric motor's output. Pump's output is the active power.Fourth, pump proper energy lossPump mechanical energy which obtains from the prime mover, has a part to transform into the liquid energy, but another part because in the pump consumes loses. In the pump all losses may divide into the following several items: 1. Hydraulic loss by the liquid in pump impact, the turbulent flow and the surface friction creates. The impact and the eddy current loss are because the liquid flow change direction produces. The liquid flows through the flow channel general meeting which contacts to present the surface friction, from this produces the energy loss is mainly decided by flow channel's length, the size, the shape, the surface roughness, as well as liquid speed of flow and characteristic.2. Volumetric loss: volumetric loss was already obtained the energy liquid to have a part to flee the result which in the pump the class and leaked outward.is 0.93～0.98 generally. Improves the packing Pump's volumetric efficiencyvring and the seal structure, may reduce the leakage, raises the volumetric efficiency.3. Mechanical loss mechanical loss refers to the impeller lap side and the pump housing friction loss between the liquid, namely the disc loses, as well as pump spindle when packing, bearing and balancing unit and so on mechanical part movement friction loss, generally before primarily.Fifth, pump's speed change--Proportionality law1. Centrifugal pump's speed change:A centrifugal pump, when its rotational speed change, its rated flow, lifting and the shaft power will have the change according to the certainproportion relations. At present, uses the frequency conversion velocity modulation electrical machinery to realize centrifugal pump's speed change, is a new important energy conservation way. 2. proportionality law expression:2121n n Q Q = 22121⎪⎪⎭⎫ ⎝⎛=n n H H 32121⎪⎪⎭⎫ ⎝⎛=n n N N In the formula, Q, H, N-- pump's rated flow, lifting and shaft power Thesubscript 1,2 express the different rotationalspeed separatelyn-- rotational speedSixth, centrifugal pump's ratio rotationCompared to the rotation is the comprehensive parameter which derives by the law of similarity, it is the operating mode function, to a pump, the different operating mode has differently compared to the rotation, for ease of carries on the comparison to the different type pump's performance and the structure, the application optimum condition (the peak efficiency spot) the ratio rotation represents this pump.When chooses the pump, may according to job requirement Q, H and unifies electrical machinery's rotational speed, calculates the n s number, determines pump's type approximately. At that time, 30<s n used the positive displacement pump generally, at that time, 30>s n used the centrifugal pump, the interflow pump, the axial flow pump and so on. Seventh,centrifugal pump'scavitation andinspirationcharacteristic1.Cavitation phenomenonsThe pumping station transportation medium's liquid condition and the gas are can transform mutually, the transformed condition is the pressure and the temperature. Under certain temperature, the liquid starts the critical pressure which vaporizes for the vaporization pressure. The temperature is higher, the liquid vaporization pressure is higher. Pump when revolution, if its overflow part local region (for example impeller blade import later somewhere), the liquid absolute pressure drops when pulled out delivers the liquid at that time under the temperature vaporization pressure, the liquid then in this place starts to vaporize, the bubble formation (air bubble internal pressure approximately wasequal to vaporization pressure). When these air bubbles along with liquid flow forward motion to high pressure region, down to around the air bubble high-pressured liquid causes the air bubble to reduce suddenly congeals. While air bubble vanishing, the liquid particle by the high speed packing hole, occurs hits mutually forms the intense pressure surge, causes the overflow part to receive the corrosion and the destruction. The above process is called the cavitation.2. Cavitation will cause serious results:(1). has the vibration and the noise.(2). is influential to pump's operating performance: When the cavitation develops the certain extent, the • steam bubble produces massively, will stop up the flow channel, will cause pump's current capacity, lifting, the efficiency and so on obviously to drop.(3). will have the destruction to flow channel's material quality: Is mainly nearby the leaf blade entrance the metal weary disintegration.3. centrifugal pump's inspiration characteristic:(1). Pump has the cavitation basic condition is: Under leaf blade entrance lowest liquid flow pressure k P <= this temperature liquid vaporization pressure v P .(2). effective net positive suction head: The pump entry (potential head is the entire flood peak which zero) the liquid has subtracts the value which the vaporization delivery head remains only, with expression.(3). pump essential net positive suction head: Liquid flow from pump inlet to impeller in minimal pressure point of force K place complete energy loss, with expression.(4). With r NPSH and a NPSH difference and relation:a NPSH >r NPSH Pump not cavitationa NPSH =r NPSH The pump starts the cavitationa NPSH <r NPSH Pump serious cavitation(5). regarding a pump, to guarantee that its safe operation does not have the cavitation, must the net positive suction head also be supposed to add asecurity allowance regarding the pump, therefore, pump's permission net positive suction head is:[]NPSH=()c1.1~NPSH5.14. Enhances the centrifugal pump anti-cavitation performance themethod to include:NPSH, is machine the pump (1). I mprovement machine pump structure, reducesrdesign question.(2). Enhancement installment effective net positive suction head. Most mainly the most commonly used method uses the irrigation inspiration installment.In addition, reduces the inspiration pipeline resistance loss as far as possible, reduces the liquid the saturated steam tension, namely when design inspiration pipeline selects caliber big as far as possible, length short, the bend and valve few, transportation liquid temperature as far as possible low and so on measures, may enhance the installment the effective cavitation remainder.5. axial force balancing unit(1). axial force production reason①Around because the impeller the both sides the fluid pressure distributed situation different (wheel cap lateral pressure is low, • wheel disk pressure high) causes axial force A1, its direction for from impeller back side direction impeller eye.②The fluid flows in and flows out dynamical reaction A2 which impeller's direction and the speed different produce, its direction and A1 are opposite, therefore line shaft directive force A=A1-A2, the direction is ordinary and A1 same (general A2 is small).(2). Axial force balanced①Uses double attracts the type impeller: The impeller lateral symmetry, the fluid from the both sides inspiration, the axial force automatic counter-balance achieves balanced.②Opens the balancing hole or installs the compensating pipe:A: Opens several balancing holes in the impeller wheel disk photograph well regarding the induction port place.B: After order to avoid the balancing hole, because the mainstream is disturbed increases the hydraulic loss, may suppose the compensating pipe to replace the balancing hole, namely uses an acorn tube leading-in point pressure to the wheeldisk back side.③Uses the balanced leaf blade: Casts several radial direction muscle piece at the back of the leaf wheel disk, the • muscle piece drives at the back of the impeller in the gap fluid to accelerate to revolve, increases the centrifugal force, •, thus causes at the back of the impeller the pressure obviously to reduce.④Using thrust bearing withstanding axial force. Generally in the small single suction pump the thrust bearing may withstand the complete axial force, prevents the pump spindle to flee moves.Eighth. centrifugal pump's operating procedure1. Centrifugal pump starts the inspection(1) Electrical machinery overhaul, before connecting the shaft coupling, inspects electrical machinery's rotation direction first to be whether correct.(2) inspection pumps out the inlet line and the attached pipeline, the flange, the valve installs whether to meet the requirement, foot bolt and grounding to be whether good, whether the shaft coupling does install.(3) jigger inspection, rotates whether normally.(4) inspection lubricating oil oil level is whether normal, refuels without the oil, and inspects the lubricating oil (fat) oil material nature.(5) turns on various cooling water valve, and inspects the pipeline to be whether unimpeded. Attention cooling water not suitable oversized or too small, will create the waste oversized, too small, then the cooling performance will be bad. Generally the cooling current of water becomes the striation(6) dozen of pumping's inlet valve, closes pump's outlet valve, and turns on the pressure gauge valve.(7) inspection machine pump's seal condition and oil seal opening. attention: The hot oil pump wants evenly before the start preheating.2. centrifugal pump's start(1) all operates the inlet valve, closes the outlet valve, the starting dynamo.(2), when the pump outlet pressure is bigger than the service pressure, inspects each work on six cylinders, turns on the outlet valve gradually.when(3) starting dynamo, if the start or has time the unusual sound, should the dump inspection, after eliminating the breakdown, immediately only then starts.when(4) start, pays attention to the human not to face the shaft coupling, by against departs offends somebody.3. the centrifugal pump stops the pump to operate(1) to close pump's outlet valve slowly.(2) shuts off electrical machinery's power source.(3) closes the pressure gauge valve.(4) parking, cannot stop the cooling water immediately, should pump's temperature only then cut off the water supply falling to 80 degrees below.(5) according to the need, closes the inlet valve, the pump body blows off.4. centrifugal pump operates when matters needing attention(1) centrifugal pump when revolution avoids the idle operation.(2) avoids when closes the outlet valve the long time revolution.(3) refuses the water used battery charger.the(4) centrifugal pump must in close in outlet valve's situation to start.中文译文：泵的概述泵是应用非常广泛的通用机械，可以说是液体流动之处，几乎都有泵在工作。

CENTRIFUGAL PUMPS IN THE CHEMICAL INDUSTRYAbstract : A centrifugal pump converts the input power to kinetic energy in the liquid by accelerating the liquid by a revolving device - an impeller. The most common type is the volute pump. Fluid enters the pump through the eye of the impeller which rotates at high speed. The fluid is accelerated radially outward from the pump chasing. A vacuum is created at the impellers eye that continuously draws more fluid into the pump . This article stresses on a series of centrifugal pumps，From a brief introduction to the principles.Keywords : centrifugal pump ,Introduction ,Working principle , Cavitation ，Mechanism of Cavitation ，Solution and Remedies1. IntroductionPump ,device used to raise ,transfer ,or compress liquids and gases .Four general classes of pumps for liquids are described below .In all of them ,steps are taken to prevent cavitation (the formation of a vacuum) ,which would reduce the flow and damage the structure of the pump .Pumps used for gases and vapors are usually known as compressors .The study of fluids in motion is called fluid dynamics.Water pump ,device for moving water from one location to another ,using tubes or other machinery .Water pumps operate under pressures ranging from a fraction of a pound to more than 10,000 pounds per square inch .Everyday examples of water pumps range from small electric pumps that circulate and aerate water in aquariums and fountains to sump pumps that remove water from beneath the foundations of homes .One type of modern pumps used to move water is the centrifugal pump .Early version of the centrifugal pump ,the screw pump ,consists of a corkscrew-shaped mechanism in a pipe that ,when rotated ,pulls water upward .Screw pumps are often used in waste-water treatment plants because they can move large amounts of water without becoming clogged with debris .In the ancient Middle East the need for irrigation of farmland was a strong inducement to develop a water pump .Early pumps in this region were simple devices for lifting buckets of water from a source to a container or a trench .Greek mathematician and inventor Archimedes is thought to have devised the first screw pump in the third century BC .Later Greek inventor Ctesibius develop the first lift pump .During the late 17th and early 18th CenturiesAD ,British engineer Thomas Savery ,French physicist Denis Papin ,And British blacksmith and inventor Thomas Newcomen contributed to the development of a water pump that used steam to power the pump’ piston .The steam-powered water pump’s first wide use was in pumping water out of mines .Modern-day examples of centrifugal pumps are those used at the Grand Coulee Dam on the Columbia River .This pump system has the potential to irrigate over one million acres of land . Also known as rotary pumps ,centrifugal pumps have a rotating impeller ,also known as a blade ,that is immersed in the liquid .Liquid enters the pump near the axis of the impeller ,and the rotating impeller sweeps the liquid out toward the ends of the impeller blades at high pressure .The impeller also gives the liquid a relatively high velocity that can be converted into pressure in a stationary part of the pump ,known as the diffuser .In high-pressure pumps ,a number of impeller may be used in series ,and the diffusers following each impeller may contain guide vanes to gradually reduce the liquid velocity .For lower-pressure pumps ,the diffuser is generally a spiral passage ,known as a volute ,with its cross-sectional area increasing gradually to reduce the velocity efficiently .The impeller must be primed before it can begin operation ,that is ,the impeller must be surrounded by liquid when the pump is started .This can be done by placing a check valve in the suction line ,which holds the liquid in the pump when the impeller is not rotating .If this valve leaks ,the pump may need to be primed by the introduction of liquid from an outside source such as the discharge reservoir .A centrifugal pump generally has a valve in the discharge line to control the flow and pressure .For low flows and high pressures ,the action of the impeller is largely radial .For higher flows and lower discharge pressure ,the direction of the flow within the pump is more nearly parallel to the axis of the shaft ,and the pump is said to have an axial flow .The impeller in this case acts as a propeller .The transition from one set of floe conditions to the other is gradual ,and for intermediate condition , the device is called a mixed-flow pump .2.The Centrifugal PumpThe centrifugal pump is by far the most widely used type in the chemical and petroleum industries .It will pump liquids with very wide ranging properties and suspensions with a high solids content including ,for example ,cement slurries ,and may be constructed from a very wide rang of corrosion resistant materials .The whole pump casing may be constructed from plastic such as polypropylene or it may be fitted with a corrosion-resistant lining .Because it operates at high speed ,it may bedirectly coupled to an electric motor and it will give a high flow rate for its size .In this type of pump ,the fluid is fed to the centre of a rotating impeller and is thrown outward by centrifugal action .As a result of the high speed of rotation the liquid acquires a high kinetic energy and the pressure difference between the suction and delivery sides arises from the conversion of kinetic energy into pressure energy . The impeller consists of a series of curved vanes so shaped that the flow within the pump is as smooth as possible .The greater the number of vanes on the impeller ,the greater is the control over the direction of the liquid and hence the smaller are the losses due to turbulence and circulation between the vanes .In the open impeller ,the vanes are fixed to a central hub ,whereas in the closed type the vanes are held between two supporting plates and leakage across the impeller is reduced .As will be seen later ,the angle of the tips of the blades very largely determines the operating characteristics of the pump .The liquid enters the casing of the pump，normally in an axial direction，and is picked up by the vanes of the impeller．In the simple type of centrifugal pump，the liquid discharges into a volute，a chamber of gradually increasing cross—section with a tangential outlet．A volute type of pump is shown in Fig.(a)．In the turbine pump[-Fig．(b)]the liquid flows from the moving vanes of the impeller through a series of fixed vanes forming a diffusion ring．This gives a more gradual change in direction to the fluid and more efficient conversion of kinetic energy into pressure energy than is obtained with the volute type．The angle of the leading edge of the fixed vanes should be such that the fluid is received without shock．The liquids flows along the surface of the impeller vane with a certain velocity whilst the tip of the vane is moving relative to the casing of the pump．The direction of motion of the liquid relative to the pump casing--and the required angle of the fixed vanes—is found by compounding these two velocities．In Fig．c，c.v u is the velocity of the liquid relative to the vane and t u is the tangential velocity of the tip of the vane ；compounding these two velocities gives the resultant velocity 2u of the liquid ．It is apparent ，therefore ，that the required vane angle in the diffuser is dependent on the throughput ，the speed of rotation ，and the angle of the impeller blades ．The pump will therefore operate at maximum efficiency only over a narrow range of conditions ．Virtual head of a centrifugal pumpThe maximum pressure is developed when the whole of the excess kinetic energy of the fluid is converted into pressure energy. As indicated below ．the head is proportional to the square of the radius and to the speed ，and is of the order of 60m for a single —stage centrifugal pump ；for higher pressures ，multistage pumps must be used ．Consider the liquid which is rotating at a distance of between r and r+dr from the centre of the pump(Fig ．d)．dThe mass of this element of fluid dm is given by 2πrdrdρ，where ρ is the density of the fluid and 6 is the width of the element of fluid 。

单级离心泵设计-翻译原文
CENTRIFUGAL PUMPS IN THE CHEMICAL INDUSTRYAbstract: A centrifugal pump converts the input power to kinetic energy in the liquid by accelerating the liquid by a revolving device - an impeller. The most common type is the volute pump. Fluid enters the pump through the eye of the impeller which rotates at high speed. The fluid is accelerated radially outward from the pump chasing. A vacuum is created at the impellers eye that continuously draws more fluid into the pump . This article stresses on a series of centrifugal pumps，From a brief introduction to the principles.Keywords: centrifugal pump ,Introduction ,Working principle , Cavitation ，Mechanism of Cavitation ，Solution and Remedies1. IntroductionPump ,device used to raise ,transfer ,or compress liquids and gases .Four general classes of pumps for liquids are described below .In all of them ,steps are taken to prevent cavitation (the formation of a vacuum) ,which would reduce the flow and damage the structure of the pump .Pumps used for gases and vapors are usually known as compressors .The study of fluids in motion is called fluid dynamics.Water pump ,device for moving water from one location to another ,using tubes or other machinery .Water pumps operate under pressures ranging from a fraction of a pound to more than 10,000 pounds per square inch .Everyday examples of water pumps range from small electric pumps that circulate and aerate water in aquariums and fountains to sump pumps that remove water from beneath the foundations of homes .One type of modern pumps used to move water is the centrifugal pump .Early version of the centrifugal pump ,the screw pump ,consists of a corkscrew-shaped mechanism in a pipe that ,when rotated ,pulls water upward .Screw pumps are often used in waste-water treatment plants because they can move large amounts of water without becoming clogged with debris .In the ancient Middle East the need for irrigation of farmland was a strong inducement to develop a water pump .Early pumps in this region were simple devices for lifting buckets of water from a source to a container or a trench .Greek mathematician and inventor Archimedes is thought to have devised the first screw pump in the third century BC .Later Greek inventor Ctesibius develop the first lift pump .During the late 17th and early 18th CenturiesAD ,British engineer Thomas Savery ,French physicist Denis Papin ,And British blacksmith and inventor Thomas Newcomen contributed to the development of a water pump that used steam to power the pump’ piston .The steam-powered water pump’s first wide use was in pumping water out of mines .Modern-day examples of centrifugal pumps are those used at the Grand Coulee Dam on the Columbia River .This pump system has the potential to irrigate over one million acres o f land . Also known as rotary pumps ,centrifugal pumps have a rotating impeller ,also known as a blade ,that is immersed in the liquid .Liquid enters the pump near the axis of the impeller ,and the rotating impeller sweeps the liquid out toward the ends of the impeller blades at high pressure .The impeller also gives the liquid a relatively high velocity that can be converted into pressure in a stationary part of the pump ,known as the diffuser .In high-pressure pumps ,a number of impeller may be used in series ,and the diffusers following each impeller may contain guide vanes to gradually reduce the liquid velocity .For lower-pressure pumps ,the diffuser is generally a spiral passage ,known as a volute ,with its cross-sectional area increasing gradually to reduce the velocity efficiently .The impeller must be primed before it can begin operation ,that is ,the impeller must be surrounded by liquid when the pump is started .This can be done by placing a check valve in the suction line ,which holds the liquid in the pump when the impeller is not rotating .If this valve leaks ,the pump may need to be primed by the introduction of liquid from an outside source such as the discharge reservoir .A centrifugal pump generally has a valve in the discharge line to control the flow and pressure .For low flows and high pressures ,the action of the impeller is largely radial .For higher flows and lower discharge pressure ,the direction of the flow within the pump is more nearly parallel to the axis of the shaft ,and the pump is said to have an axial flow .The impeller in this case acts as a propeller .The transition from one set of floe conditions to the other is gradual ,and for intermediate condition , the device is called a mixed-flow pump .2.The Centrifugal PumpThe centrifugal pump is by far the most widely used type in the chemical and petroleum industries .It will pump liquids with very wide ranging properties and suspensions with a high solids content including ,for example ,cement slurries ,and may be constructed from a very wide rang of corrosion resistant materials .The whole pump casing may be constructed from plastic such as polypropylene or it may be fitted with a corrosion-resistant lining .Because it operates at high speed ,it may bedirectly coupled to an electric motor and it will give a high flow rate for its size .In this type of pump ,the fluid is fed to the centre of a rotating impeller and is thrown outward by centrifugal action .As a result of the high speed of rotation the liquid acquires a high kinetic energy and the pressure difference between the suction and delivery sides arises from the conversion of kinetic energy into pressure energy . The impeller consists of a series of curved vanes so shaped that the flow within the pump is as smooth as possible .The greater the number of vanes on the impeller ,the greater is the control over the direction of the liquid and hence the smaller are the losses due to turbulence and circulation between the vanes .In the open impeller ,the vanes are fixed to a central hub ,whereas in the closed type the vanes are held between two supporting plates and leakage across the impeller is reduced .As will be seen later ,the angle of the tips of the blades very largely determines the operating characteristics of the pump .The liquid enters the casing of the pump，normally in an axial direction，and is picked up by the vanes of the impeller．In the simple type of centrifugal pump，the liquid discharges into a volute，a chamber of gradually increasing cross—section with a tangential outlet．A volute type of pump is shown in Fig.(a)．In the turbine pump[-Fig．(b)]the liquid flows from the moving vanes of the impeller through a series of fixed vanes forming a diffusion ring．This gives a more gradual change in direction to the fluid and more efficient conversion of kinetic energy into pressure energy than is obtained with the volute type．The angle of the leading edge of the fixed vanes should be such that the fluid is received without shock．The liquids flows along the surface of the impeller vane with a certain velocity whilst the tip of the vane is moving relative to the casing of the pump．The direction of motion of the liquid relative to the pump casing--and the required angle of the fixed vanes—is found by compounding these two velocities．In Fig．c，c.u is the velocity of the liquid relative to the vane and t u is the tangential velocity vof the tip of the vane；compounding these two velocities gives the resultant velocityu of the liquid．It is apparent，therefore，that the required vane angle in the diffuser 2is dependent on the throughput，the speed of rotation，and the angle of the impeller blades．The pump will therefore operate at maximum efficiency only over a narrow range of conditions．Virtual head of a centrifugal pumpThe maximum pressure is developed when the whole of the excess kinetic energy of the fluid is converted into pressure energy. As indicated below．the head is proportional to the square of the radius and to the speed，and is of the order of 60m for a single—stage centrifugal pump；for higher pressures，multistage pumps must be used．Consider the liquid which is rotating at a distance of between r and r+dr from the centre of the pump(Fig．d)．dThe mass of this element of fluid dm is given by 2πrdrdρ，where ρ is the density of the fluid and 6 is the width of the element of fluid。

附录(一):Optimizing centrifugal pump operationCentrifugal pump operation is more than switching the pump on and directing the discharge flow to the required delivery point. This holds true even when a control value is installed in the discharge line for the purpose of flow or level control .A few very essential operating guidelines must be adhered to if early bearing or seal failure, premature erosion of internal wetted surfaces, or metal-to-metal contact of internal rotating and stationary surfaces, is to be avoided. In this article, Stan Shiels addresses the fundamentals of proper centrifugal pump operation and the most common areas of improper centrifugal pump operation. It is assumed that the pump has been successfully commissioned.The most common cause of centrifugal pump failure, separate from those causes associated with maintenance and/or design, but associated with how the pumps are operated may be summarized as follows:1. Insufficient suction pressure to avoid cavitation.2. Excessively high flow rate for the net positive suction head available (NPSHA).3. Prolonged operation at lower than acceptable flow rates.4. Operation of the pump at zero or near zero flow rate.S. Improper operation of the pump in parallel.6. Failure to maintain adequate lubrication for the bearings.7. Failure to maintain satisfactory flushing to mechanical seals.Insufficient suction pressure to avoid cavitation.While the provision of sufficient suction pressure to avoid cavitation may seem straightforward, requiring only that the net positive suction head available(NPSHA) be always greater than or equal to the net positive suction head required (NPSHR) by the pump, some misconceptions need to be revealed. When the pump manufacturer develops the pump's NPSHR curve, the calculated values of NPSHR are for conditions where theexpected head (as determined by the previously performed pumphydraulic performance test) has fallen of by 3% for that specific flow rate. This means that mild cavitation will exist when the NPSHA equals the NPSHR. Because of this a comfort margin of 3 feet, or 1meter, isrecommended, when determining the minimum acceptable NPSH margin:(NPSHA-NPSHR).The following piping faults will require an NPSH margin greater than 3 feet(1 meter) to ensure the absence of cavitation.~Where the inlet piping configuration is such that a number of 90 degree turns occur, in different planes, fairly close to the pump suction, the resultant fluid swirl will cause cavitation to occur, on occasion, even when the NPSH margin is 2 to 3 feet.~Where an eccentric inlet reducer is positioned in the pipe such that itforces asymmetric flow into the suction of a double suction pump. The side of the double suction impeller that receives the disproportionately higher percentage of the total flow will incur cavitation at an NPSHA much higher than the NPSHR indicated on the manufacturer's test curve.Excessively high flow rate for the NPSH availableBased upon the simple fact that NPSHA decreases as flow rate increases, and NPSHR increases as flow rate increases, there should be considerable effort place on ensuring that the point of intersection of these two parameters is not reached. This concept is illustrated in Figurel.Many centrifugal pumps are installed in a system, which cannot pro vide adequate suction pressure to avoid cavitation, if operated at flow rates much above their best efficiency point (BEP). It is probably never intended to operate these pumps in such a region, but transient conditions can often lead to intended operation at much higher than expected flow rates. One example is the case where a recycle control value has been installed to ensure that the pump is not operated below a minimum acceptable flow rate. At very low or zero process flow the recycle control value may attain a position of greater than 50% open. This of itself is not a problem, but the extremely high flow rate may occur when the process control value is again asked to open, and does so rather quickly. When the process control valve is faster acting than the recycle control valve, the combined process and recycle flows may necessitate a higher NPSHR than the suction system can provide.Manual operation must also be handled carefully when simple transfer operations between vessels is called for. At the start of such operation the receiving vessel may have a very high level. This leads to a negative static head, which can lead to an initial high flow rate until the level rises in the discharge vessel. This is a particularly risky operation where piping system resistance is low on the discharge side, but a relatively long section of suction piping exists.Prolonged operation at lower than acceptable flow ratesA centrifugal pump is most comfortable operating between 85% and 110% of its best efficiency point (BEP). However, by far the great majority of centrifugal pumps are forced to operate outside of this range. The degree to which it is acceptable to operate outside of this range is a function of two primary parameters:Suction Specific Speed (Ss) and Specific Speed (S). These parameters may be calculated for a pump provided the following data is known: For maximum diameter impeller:BEP FlowNPSHR at BEP FlowHead at BEP FlowPump Operating Speed (RPM)The following formulae allow Ss and S to be calculated:()0.50.750.50.75()()()bep bepbep bep SpecificSpeed S REP Q H SuctionSpecificSpeed Ss RPE Q NPSHR=⨯÷=⨯÷Where: QPM is pump rotational speed in revolutions per minute.bep Q flow at BEP for maximum diameter impeller.bep H is pump head at BEP for maximum diameter impeller.bep NPSHR is the pump net positive head required at BEP for maximum diameter impeller.The acceptable minimum continuous flow rate, which a centrifugal pump can be expected to endure without incurring damage or premature failure is also affected by a number of other parameters: such as, impeller head, fluid specific gravity , and percentage of total running time spent at the lower flow rate. When the pump's specific speed and suction specific speed are known the approximate percentage of the pump's maximum impeller diameter BEP flow at which suction recirculation can be expected to occur may be estimated.From this estimate the approximate minimum acceptable continuous flow rate for that specific pump may be estimated. Impeller geometry can be optimized to improve on initial estimates and, when conditions are marginal, it is always advisable to consult with the manufacturer's application engineer before deciding on the acceptable minimum continuous flow rate.A subsequent article can expend further on this much debated area of centrifugalpump operation. In the interim it is suggested that pump users request the minimum "stable" continuous flow rate recommended from the pump manufacturer, based upon the onset of flow instability .Impeller geometry can impact the "Cavitation Coefficient" which is defined by the following formula:211(2)u g NPSH u δ=⨯÷Where1u δ is the cavitation coefficientg is the gravitation constantNPSH is net positive suction head1u is fluid circumferential velocity at impeller entryThis is a dimensionless coefficient and would be valid for all geometrically similar pumps, independent of their size and speed of rotation.Operation of the pump at zero or near zero flow rateCentrifugal pumps are often used to pump out vessels, often to zero level. The pumps can, at times, be left unattended. If the level is allowed to fall to the point where the pump is allowed to run dry , failure of the mechanical seal will often follow rapidly. In such applications even a small recycle flow back to the suction vessel will not alleviate the problem, as the pump will still be able to empty the vessel. Many such applications are best protected by the installation of dual pressurized mechanical seals which will remain lubricated even during periods of completely dry running. In non hazardous applications a pump sealed with packing will survive better if the packing is lubricated from an external source; the source must, of course, be compatible with the fluid being pumped.Where batch delivery is normal operation, such that the pump will operate for long periods, but delivery is intermittent, a small continuous recycle flow back to the suction source will help to protect the pump during periods when delivery stops (typically by closing the delivery valve). Lack of some of the recycle protection for a centrifugal pump, which will see periods of zero flow, will certainly cause frequent pump failure. Any centrifugal pump operated at zero flow for even a few minutes will vapour temperature. It is worth remembering that once a pump has vapour-locked it will not generate any noticeable discharge pressure differential. Usually it is necessary to stop the pump and allow the gas to condense back into liquid, before pumping can resume.Improper operation of the pump in parallel.This topic has been covered in detail in a previous "Pump Academy" article, but the basics are worthy of mention in terms general centrifugal pump operating philosophy. The following principles should be applied to any operation of centrifugal pumps, which requires either continuous or intermittent parallel operation.~Shut-off heads of all pumps operating in parallel should be comparable typically as close as possible, with difference of no more than 2%or 3% recommended~V ery flat performance curves in one or more of the pumps operating in parallel is to be avoided;a drop of 10% to 20% between the shut-off and rated points is recommended. The point of hydraulic shut-off of the more worn pump of two initially identical pumps operating in parallel is shown in Figure 2, for high head rise to shut-off and low head rise to shut-off.~Multistage pumps, or expensive single-stage or two-stage pumps designed to operate in parallel, should be protected by low flow shut-down devices to avoid severe damage from occurring at transient low combined flow conditions. While the pumps may be identical, performance differences occur over time, and the better performing pump will effectively "shut-off" the weaker pump below a specific combined flow rate. The low flow shut-down will prevent the major damage that often results from such occurrences.~inlet and discharge piping configurations and lengths should be comparable between the pump and the suction and discharge headers. Proper piping configuration for pumps operating in parallel should include suction and discharge headers of larger diameter than the lines leading to and from the individual pumps. Differences in suction and/or discharge piping configuration will always lead to a disparity in pump flow rates.Failure to maintain adequate lubrication for the bearingsThis is a simple statement and sounds too fundamental to be ignored, but, even among those diligent pump operators who strive to maintain adequate lubrication, some inadvertent mistakes are made. Lubrication of rolling element bearings is the subject here. They may be oil lubricated or grease lubricated. The complete topic requires more attention than can be afforded in this text, but the basic essentials always hold true and can only be ignored at the risk of early pump failure.Oil lubrication is of three basic types: forced feed with a pressurized filtered and cooled oil supply to the bearings in a closed loop system; oil bath; and oil mistThe forced feed system is the most complicated and usually incorporates a low oil pressure shutdown protection; it is normally only present in large multistage pump installations. The key areas of concern are:~Maintenance of the correct viscosity of the oil and periodic monitoring for changes in viscosity and/or Total Acid Number (TAN) and the presence of water in the oil.~On occasion ferrographic analysis for the presence of wear particles helps to diagnose impendent bearing damage.~Lube oil cooler performance decline may lead to elevated temperatures and periodic oil temperature monitoring is also essential.~Oil filter differential pressure and main oil supply pressure to the bearings also requires frequent attention.A housing for oil bath lubrication normally incorporates a constant level oiler, although some pump users have chosen to seal their bearing housing and use synthetic oil, changing the oil only once every two or three years. For those bearing housings incorporating a constant level oiler the following basic principles apply:~Use of the correct viscosity oil for the operating temperature of the bearing (refer to the bearing manufacturer's literature).~Maintenance of a reserve of oil in the constant level oiler.~Clean storage of the make-up oil to prevent foreign material and/or moisture from entering the bearings.~Observance of the deterioration in the oiler level一remember, oilers whose level never falls over time may have a blocked connection between the oiler and the bearing housing.Oil mist lubrication requires that the same viscosity oil be used as for oil bath lubrication. On occasion a grade lighter oil may be used as the oil is being constantly replenished, although this approach should be taken with caution. While most oil mist systems incorporate an alarm for loss of oil mist pressure, each bearing housing should be periodically checked to confirm adequate venting of oil mist from the housing, and for proper condensation and drainage of bearing housing oil mist condensate collection pots.Grease lubrication of rolling element bearings requires proper attention to the following:~The type of grease used. A stiffer grease for higher speeds (3000 RPM and above) and a softer grease for lower speeds.~The grease should essentially contain the same viscosity of oil in it as that required for oil bath luibrication.~The amount of grease. This is of particular importance where pump operators are responsible for regreasing of bearings, as a major cause of failure of grease lubricated pump bearings is overgreasing. The idea that more is better is very wrong here.~Compatibility of greases. When regreasing it is essential that the grease to be added is compatible with the originally installed grease.As is the case for oil type selection, it is recommended that the bearing applications engineering department be consulted, when in doubt about which grease is best for each specific application.Failure to maintain satisfactory flushing to mechanical sealsThe flushing plan for a mechanical seal is the means of controlling the environment in which the seal operates. It follows then that any event that alters the intended flushing flow parameters will alter the seal's environment and may lead to seal failure. The following parameters, for some of the most commonly utilized seal flushing arrangements, should be regularly monitored for mechanical seals:Pump discharge flush to the seal to confirm that the temperature is correct. The dischargeflush should be at the same temperature as the pump discharge flow. In hot service a cooler flush will indicate lack of sufficient flow; this is often the only means available of checking flow, as most discharge flush plans do not have a flow indication.Suction flush from the seal cavity to the pump suction should also be checked for temperature. This may require that the temperature be checked initially to set a "benchmark." Any noticeable increase in this flush return to the pump suction may indicate a flow restriction.Cooled discharge flushes require adequate cooling to attain the required flush temperature. Discharge flush coolers foul over time and often the flush temperature is allowed to rise to the point of seal failure before cooler fouling is discovered. Both the cooling water differential temperature and the flush supply temperature to the seal should be monitored and the cooler replaced of cleaned before fouling progresses too far.Dual unpressurized seals rely on a head of liquid in a seal pot to provide a small pressure differential between the seal interspace and atmosphere. Both the seal pot level and the seal pot pressure should be observed for signs of change. Dualunpressurized seals are often utilized in volatile fluid service, where the vapour pressure is above atmospheric and any normal primary seal vapour leakage can be vented through the seal pot orifice to a safe collection point; a noticeable increase in seal pot pressure would indicate a primary (inner) seal failure. A reduction in seal pot level would indicate an outer seal failure.Dual pressurized seals incorporating a seal pot similarly should be monitored. The seal pot pressure must be maintained at a pressure above the seal cavity pressure for satisfactory seal operation. A reduction in seal pot level will indicate either a primary or or outer seal failure; further observation for obvious leakage of the outer seal is required to determine which one has failed. Loss of seal pot pressure may indicate a failure of the pressure blanketing system. Alarms are usually incorporated in dual seal systems incorporating seal pots. It is still advisable to monitor these parameters to allow early warning of loss of adequate seal flushing.Dual pressurized seals utilizing a flow-through barrier fluid system should have regular checks carried out for barrier fluid inlet and outlet temperatures and pressures. If the barrier fluid return pressure is allowed to drop to a value below the seal cavity (pump side) pressure, seal failure will follow in a pump media containing abrasives. Not all such systems have flow indication and a rise in differential temperature will usually indicate an increase in leakage rate of the inner seal, but could signify a reduction in barrier fluid flow rate; where flow rate is not subject to change it normally indicates an increase in inner seal leakage rate. A check of barrier fluid inlet pressure to the seal will assist in the diagnosis. A drop in barrier fluid return pressure, usually accompanied by arise in return temperature, is almost always associated with an inner seal failure.A last wordWhile there are many more causes of operational failure of centrifugal pumps, this discussion has dealt with the most frequently contributing areas. The operators of centrifugal pumps must extend their scope into the area of "ownership: Operators need to become familiar with tow these pumps operate, their key areas to monitor, and what to look for. It could also be said that many large process plants, which operate a large number of centrifugal pumps, do not provide sufficient pump training to permit the operating staff to understand key operating principles and satisfactory monitoring guidelines. We enjoy driving our automobiles. When have maintenance carried out: oil change, engine tune-up, transmission checked, brakes overhauled,tires renewed, fluid levels checked, hoses replaced, etc. most of us do not drive our cars until the oil breaks down completely and seizes the engine, the coolant hose blows, the brakes fail, the tires lose their tread, or the transmission fails. Periodic checks allow us to avoid such failures. We own our cars and do not want to incur the cost and inconvenience of such failures. A similar frame of mind toward centrifugal pump operation, supported by a proper program of operator training will pay dividends in terms of pump reliability and the cost of pump operation, and avoid some costly process debits.附录（二）：优化离心泵的操作操作离心泵不仅指打开水泵阀门、接通排水管、导出排放液体到规定传输点还包括在排水管中安装控制阀以控制调节流量和液位等为了避免早期轴承或密封失效、内部潮湿表面过早浸蚀、以及内部旋转和固定部分金属表面发生摩擦等状况发生，在操作离心泵时须遵循一定的操作原则, 本文中，Stan Shiels给出了离心泵合理操作的基本法则和不正确使用离心泵的常见误区本文假设离心泵正常投入运行。

coefficient of impeller inlet,the value generally is0.4without impact inflown s specific speed0IntroductionAs an important part of the centrifugal pump,the hy-draulic design quality of the impeller often determines its performance.The common centrifugal pump impeller design methods are mainly classified into forward design and in-verse design.The inverse design is difficult to process due to the complex shape of the blades,so it is less applied to actual engineering.The forward design conducts simulation analy-sis on a given product and make repeated corrections to the geometric model according to the analysis results until the better hydraulic performance impeller is obtained.However,this process takes a long time and heavy repetitive work,which results in a long product development cycle.In order to solve the above problems,more and more en-gineers apply the optimization ideas to the research and de-velopment of impellers.Yuan et al.（2014）[1]used the orthog-onal design method to optimize the design of automobile cooling water pump.The results verified the feasibility of or-thogonal design and obtained the influence of impeller pa-rameters on the performance of cooling water pump.Xiao and Wang （2006）[2]used combinatorial optimization strategy to optimize the design of the centrifugal pump impeller and achieved good results.However,at present,most optimiza-tion designs are single-objective with certain limitations.This paper takes centrifugal pump impeller as the re-search object,and takes hydraulic efficiency and NPSHr as optimization objectives.Confirming the weight of objectives with the super-transitive approximate method,the multi-ob-jective optimization problem is transformed into a single-ob-jective optimization problem.The excellent intelligent opti-mization algorithm is combined to find the optimal solution within the range of each design parameter.1Parameterization of Impeller Model1.1Parameterization of Meridian PlaneFig.1shows the shape of the blade meridian.In this pa-per,the parameterization of meridional plane is realized by using Bezier curve.The shroud and hub profiles are con-trolled by Bezier curves with 5control points,respectively.As long as the coordinates of the control points P2,P3,P4,P7,P8,and P9are modified,the shape of the meridional plane can be changed.In order to reduce the number of inde-pendent variables,P3and P8are selected as variables.The position of the blade inlet edge on the shroud and hub is ad-justed by modifying points P11and P12.Axial length of im-peller is controlled by Deta Z.1.2Parameterization of 3D Blade ShapeThe 3D blade shape is mainly controlled by parameterssuch as the inlet angle,outlet angle,wrap angle and blade thickness.Based on 5stream surfaces （including shroud and hub ）,this paper calculates the inlet and outlet ongles of the blades on each stream surface.Blade wrap angle is abtained by point-by-point integration method.The change law of blade wrap angle and blade thickness is obtained by calcula-tion,the profile of each flow surface is obtained by integrat-ing them,and finally the 3D blade shape is generated.2Numerical SimulationWith model determined ，it needs to be numerically sim-ulated to obtain the hydraulic performance.Because of per-formance comparison between optimization models is the fo-cus here,and no precise computation is required,the mesh and solution accuracy can be reduced appropriately.As long as all models use the same mesh resolution,the comparison results of different models have reference value.In order to shorten the simulation time,the k-e model is used to calcu-late the flow field in the whole flow passage of the centrifu-gal pump under steady state.3Optimization ObjectiveThe relationship between optimization objectives and in-dependent variables is established by the excellent intelligent optimization algorithm.Then the optimal solutions within the range of variables are obtained by continuously perform-ing random combinations between independent variables.3.1Hydraulic Efficiency ObjectiveThe hydraulic efficiency of a centrifugal pump is de-fined as follows,η=ρgQHP（1）According to the above formula,on the premise that the head meets the design conditions,increasing the hydraulic ef-ficiency ηis to reduce the power P .This gives the following objective function,f 1=min ()P （2）3.2NPSHr ObjectiveNPSHr of a centrifugal pump is defined as follows,NPSHr =λ1v 212g +λw 212g （3）v 1=4Qπ()d 2s -d 2h ηv（4）Fig.1Schematic Diagram of Parameterization of MeridianPlaneFig.2Schematic diagram of parameterization of 3D blade shapeChinese Journal of Turbomachinery Vol.63，2021,No.6ηv =11+0.68n -23s （5）w 1=u 21+v 21-2u 1v u 1（6）Single-stage single-suction centrifugal pump inlets are usually straight conical,namely without inlet preswirl,which gives,v u 1=0u 1=πnd s60（7）According to formula （3）,NPSHr actually represents the lowest pressure drop at the pump inlet.If this value is small,the energy loss from the pump inlet to the lowest pres-sure position is the smallest,which means that the cavitation resistance of the pump is better.Thus,the other objective function is,f 2=min ()NPSHr （8）3.3Determinationof Optimization ObjectiveWeightsFor multi-objective optimization,the weight of each op-timization objective is different.This paper hopes that the im-portance of efficiency in optimization is higher than the cavi-tation resistance of pump.The weight coefficients of the cen-trifugal pump efficiency and NPSHr are determined by the super-transitive approximate method.Then we will systemat-ically explain how the super-transfer approximation method reasonably stipulates the weight coefficient of the optimiza-tion target.1）Generate a binary comparison matrix AIt is difficult to directly define the specific weight ωm of the m goal in general,but it is easier to compare the weights between the two targets.Assuming that there are n optimiza-tion target values in total,n （n -1）/2comparisons will be made between the weight coefficients of the two targets.Now suppose the comparison value of the i-th target to the j-th target is a ij ,when a ij is greater than 1,it means that the im-portance of the i-th target is greater than the j-th ;When a ij is less than 1,it means that the importance of the j-th target is greater than the i-th ;when a ij =1,it mean that the two goals are equally important.Therefore,a binary comparison matrix A can be generated,and any element a ij ≠1/a ij in matrix A .2）Construct complementary matrix A （n ）Constructing complementary matrix A （1），A （2），…A （n ）,where complementary matrix A （i ）=（a 1（i ），a 2（i ），…,a n （i ））T,the i-th row element a i （i ）of the complementary matrix A （i ）has the same importance as the i-th row a i of the matrix A ,the other row elements of the complementary matrix are shown by the following formula:a (i )1=(a i 1)-1a (i )i （9）a (i )n =(a n 1)-1a (i )i （10）3）Construct super-transitive approximation A*A *=(a *ij )n ×n （i ，j =1,2…，n ）（11）a *ij =(a ()1ij ×a ()2ij ×,…,×a ()n ij )1/n （12）Here a ij （1）,a ij （2）,...,a ij （n ）represent the elements of matrix A （1）,A （2）,...,A （n ）in the i -th row and j -th column respectively.4）Eigenvector method to obtain weight coefficientFind the eigenvectors of the super-transfer approximatematrix A *,The eigenvector component corresponding to the maximum eigenvalue is the weight coefficient of the corre-sponding target,as shown in equation （13）;ìíîïï()A *-αmax I ω=0∑i =1nωi=1（13）In the formula,ωis the eigenvector corresponding to the maximum eigenvalue αmax of A *,and its component ωi （i =1,2,...,n ）is the weight coefficient of the corresponding ob-jective function.In this paper,there are 2optimization goals,that is,n =2.The importance of the efficiency in this paper is about twice the cavitation resistance of the pump.The weight coefficients corresponding to each optimization goal finally obtained according to the above steps are shown in equation （14）:ω=（ω1，ω2）T =（0.647，0.353）T（14）In the formula,ω1and ω2respectively represent the weighting coefficient of the efficiency of the centrifugal pump and of the anti-cavitation allowance.Therefore,the fi-nal optimization objective equation is,f =0.647*f 1+0.353*f 2（15）4Intelligent Optimization MethodIn this paper,an intelligent optimization method based on machine learning was chosen for multi-objective optimi-zation of centrifugal pump,and the optimization algorithm includes Mode Pursuing Sampling （MPS ）,Pareto Set Purs-ing （PSP ）and Radial Basis Function based High Dimension-al Model Representation （RBF-HDMR ）.It is particularly good at solving some large variables,strong constraints and black box problems.Moreover,the optimization algorithm is automatically matched according to the optimization objec-tives,optimization variables and constraints,without the need for artificial selection.5Results and DiscussionsThe low specific speed centrifugal pump is selected for this optimization case,and the specific parameters are shown in Tab.1.With the optimization variables determined,the valuerange of each optimization variable must be considered rea-sonably.If the value range is too large,the optimization time will be increased.If the value range is too small,the optimal solution may be missed.Considering the geometric parame-ters of the initial model,the value range of each variable are determined as shown below.0.055m ≤d s ≤0.1m 0.17m ≤d 2≤0.25m 0.005m ≤b 2≤0.015m 0.03m ≤DetaZ ≤0.035mTab.1Rated parameters of

plane and the 3D blade shape be-fore and after optimization,respectively.That means that the hydraulic efficiency and cavitation performance of the cen-trifugal pump is proved obviously after optimized.For the purpose of obtaining the performance of the centrifugal pump before and after optimization in more de-tail,three monitoring points are set in the volute,which mon-itor pressure

monitoring point P3Chinese Journal of Turbomachinery Vol.63，2021,No.6According to the pressure distribution before optimiza-tion in Fig.6~Fig.8,The pressure fluctuation at point P3 near the tongue in Fig.8is more severe and the pressure am-plitude is larger compared with the other two points.It means that the pressure fluctuation near the tongue is more significant than other areas because of the strong coupling in-terference between the impeller and the volute.The pressure curve of point P2fluctuates more strongly than that of point P1,because point P2is closer to point P3,so it is more sus-ceptible to the influence of the wake caused by the blade sweeping the septum tongue.Comparing the pressure curves of different positions of the volute before and after optimization,it can be seen that: the pressure fluctuations of after optimized are more stable and the fluctuation amplitudes decreases,which means that the stability of the pump has been improved overall.Fig.9shows the distribution of total gas volume frac-tion before and after optimization.As can be seen from the figure,the gas volume fraction of leading eage after optimi-zation is much lower than before optimization,which means that the cavitation performance of leading blade is improved obviously.This shows that the optimal design issuccessful.6ConclusionThis paper proposes a multi-objective optimization anal-ysis method using CFD technology,which is used to realizeparametric design of centrifugal pump flow components byintegrating CFD pre-processing,solution and post-process-ing.Analysis shows,compared with the model before optimi-zation,the hydraulic efficiency at the design point is in-creased by4.24%,NPSHr is reduced by1.49m,and the pres-sure fluctuation at different positions of the volute is signifi-cantly decreased after optimization.It shows that the optimi-zation design is useful and can be generalized to the optimi-zation design of other rotating machinery

附录A译文（一）离心泵使用时的调节方式与能源耗损分析离心泵是广泛应用于化工工业系统的一种通用流体机械。
它具有性能适应范围广（包括流量、压头及对输送介质性质的适应性）、体积小、结构简单、操作容易、操作费用低等诸多优点。
通常，所选离心泵的流量、压头可能会和管路中要求的不一致，或由于生产任务、工艺要求发生变化，此时都要求对泵进行流量调节，实质是改变离心泵的工作点。
离心泵的工作点是由泵的特性曲线和管路系统特性曲线共同决定的，因此，改变任何一个的特性曲线都可以达到流量调节的目的。
目前，离心泵的流量调节方式主要有调节阀控制、变速控制以及泵的并、串联调节等。
由于各种调节方式的原理不同，除有自己的优缺点外，造成的能量损耗也不一样，为了寻求最佳、能耗最小、最节能的流量调节方式，必须全面地了解离心泵的流量调节方式与能耗之间的关系。
1 泵流量调节的主要方式1.1 改变管路特性曲线改变离心泵流量最简单的方法就是利用泵出口阀门的开度来控制，其实质是改变管路特性曲线的位置来改变泵的工作点。
1.2改变离心泵特性曲线根据比例定律和切割定律，改变泵的转速、改变泵结构（如切削叶轮外径法等）两种方法都能改变离心泵的特性曲线，从而达到调节流量（同时改变压头）的目的。
但是对于已经工作的泵，改变泵结构的方法不太方便，并且由于改变了泵的结构，降低了泵的通用性，尽管它在某些时候调节流量经济方便[1]，在生产中也很少采用。
这里仅分析改变离心泵的转速调节流量的方法。
从图1中分析，当改变泵转速调节流量从Q1下降到Q2时，泵的转速（或电机转速）从n1下降到n2，转速为n2下泵的特性曲线Q-H与管路特性曲线He=H0+G1Qe2（管路特曲线不变化）交于点A3(Q2，H3)，点A3为通过调速调节流量后新的工作点。
此调节方法调节效果明显、快捷、安全可靠，可以延长泵使用寿命，节约电能，另外降低转速运行还能有效的降低离心泵的汽蚀余量NPSHr，使泵远离汽蚀区，减小离心泵发生汽蚀的可能性[2]。
缺点是改变泵的转速需要有通过变频技术来改变原动机（通常是电动机）的转速，原理复杂，投资较大，且流量调节范围小。
1.3泵的串、并连调节方式当单台离心泵不能满足输送任务时，可以采用离心泵的并联或串联操作。
用两台相同型号的离心泵并联，虽然压头变化不大，但加大了总的输送流量，并联泵的总效率与单台泵的效率相同；离心泵串联时总的压头增大，流量变化不大，串联泵的总效率与单台泵效率相同。
2不同调节方式下泵的能耗分析在对不同调节方式下的能耗分析时，文章仅针对目前广泛采用的阀门调节和泵变转速调节两种调节方式加以分析。
由于离心泵的并、串联操作目的在于提高压头或流量，在化工领域运用不多，其能耗可以结合图2进行分析，方法基本相同。
2.1 阀门调节流量时的功耗离心泵运行时，电动机输入泵轴的功率N 为：/N QH νη=式中N ——轴功率，W ；Q ——泵的有效压头，m ；H ——泵的实际流量，3/m s ；ν——流体比重，3/N m ；η——泵的效率。
当用阀门调节流量从1Q 到2Q ，在工作点2A 消耗的轴功率为：222/NA Q H νη=23Q H ν——实际有用功率，W ；223()Q H H ν-——阀门上损耗得功率，W ；22(1/1)Q H νη-——离心泵损失的功率，W 。
2.2变速调节流量时的功耗在进行变速分析时因要用到离心泵的比例定律，根据其应用条件，以下分析均指离心泵的变速范围在±20%内，且离心泵本身效率的变化不大。
用电动机变速调节流量到流量2Q 时，在工作点3A 泵消耗的轴功率为：323/NA Q H νη=同样经变换可得：32323(1/1)NA Q H Q H ννη=+-式中23Q H ν——实际有用功率，W ；23(1/1)Q H νη-——离心泵损失的功率，W 。
2.3能耗对比分析3结论对于目前离心泵通用的出口阀门调节和泵变转速调节两种主要流量调节方式，泵变转速调节节约的能耗比出口阀门调节大得多，这点可以从两者的功耗分析和功耗对比分析看出。
通过离心泵的流量与扬程的关系图，可以更为直观的反映出两种调节方式下的能耗关系。
通过泵变速调节来减小流量还有利于降低离心泵发生汽蚀的可能性。
当流量减小越大时，变速调节的节能效率也越大，即阀门调节损耗功率越大，但是，泵变速过大时又会造成泵效率降低，超出泵比例定律范围，因此，在实际应用时应该从多方面考虑，在二者之间综合出最佳的流量调节方法。
（二）泵在CAD中的原理方案设计模型论文摘要：在详细分析泵行业中CAD状况的基础上，阐述了建立水泵原理方案设计模型的必要性。
考虑现有的设计方法模型的特点以及水泵原理设计的自身规律，在面向对象设计模型的基础上融合了逐步求精模型的闭环设计思想，在功能分解中采用了Function-Behavior-State(FBS)方法，提出了一个原理方案设计模型。
并进一步将该模型应用于泵的原理方案设计的一实例中，得到了一个较为完整的水泵原理设计流程，表明此模型具有可操作性、可重用性、可交换性等特点。
1 引言自90年代初我国实施CAD应用工程以来，在水泵行业开展CAD设计虽普遍受到重视，但基本仍处于初级的CAD绘图阶段，主要是应用于整个设计过程中的“中下游”设计阶段，即设计方案的具体实现阶段，其本质上属于面向零件的细节设计。
CAD的发展趋势是不仅支持面向零件的细节设计，更重要的是支持概念设计与方案设计等“上游”设计，即是设计过程中最主要的创造性阶段［1］。
在产品设计过程中，创新性表现最为集中、最为突出的阶段是产品的原理方案设计阶段。
为适应泵的设计创新需要，有必要对水泵原理方案设计机理进行研究，建立一个满足水泵设计实际需要的建模方法。
在对泵的设计过程进行总体分析，针对泵的产品特点，总结设计过程中的设计规律，探讨其设计创新机理，并适应计算机辅助设计的需要，建立反映泵的设计经验知识、设计方法以及设计规范的原理方案设计模型，并将其与已有的“中下游”设计模型耦合，以做到真正支撑和辅助设计全过程。
2模型设计方法方案设计是设计过程中，在阐明任务要求后，通过抽象化认识本质问题，建立功能结构，通过寻求合适的作用原理并将其组合成作用结构，从面确定原理解(原理方案)［2］。
方案设计是在原理上确定一个解。
其工作步聚如图1所示。
图1方案设计的工作步聚在建立泵原理方案设计模型中主要涉及两方面的知识［3］：(1)设计方法学知识，即解决产品设计进程的一般性理论、研究进程模式、战略与各步骤相应的战术。
其中包括面向全过程的设计方法和对于方案设计过程中特定的设计方法。
(2)设计对象领域的专业知识，即关于泵这种具体的流体通用机械中所涉及的专业领域的知识。
2.1 设计方法面向全过程的设计方法及模型基本可以分成三种［4］：(1)面向对象设计模型，它代表着设计方法学的组装创新设计阶段；(2)GDT(General Design Theory)模型，它能体现创新设计方法学的创新思维过程(分解、映射、综合)，代表着开环创新设计阶段；(3)逐步求精模型，它充分体现了人的创新思维模式：继承中创新、反复迭代，代表着工程设计方法学的闭环控制创新设计阶段。
这种方法认为设计过程是一个逐步求精过程。
它的最大优点是存在解的评价层，允许对解进行反馈控制，进行产品优化。
因此它是一个闭环设计方法，比较符合工程设计人员的思维模式。
方案设计中关键性的一步就是如何进行产品设计要求的功能分解。
因为产品的设计要求是最精炼的产品功能描述，而形成产品的却是许许多多完成一定功能的零部件的组合，如何将抽象的产品设计要求转换为具体的、现实的功能要求充分体现了人的创造活动。
对这方面的研究，焦点主要集中在功能分解的依据上，有两种方法比较典型：一种以Robert Hsturges为代表，以价值工程理论(VE)为背景，采用功能分解，称为功能逻辑分解方法；另一种以Yasushi Umeda为代表，以人的认知模型为背景，采用行为分解，称为Fuction Behavior State(FBS)方法［5］。
虽然两者都处于发展之中，但是文献［4］认为后者的分解依据更贴近工程设计的思维模式。
2.2泵设计领域的专业知识(泵设计的特点)泵设计是一项复杂的过程，在设计中各种因素互相影响，使满足给定要求的水泵有不同的设计方案或结果，因此必须找到其中最优的一个。
这是一个不断探索，多次循环，逐步深化的判断求解过程［6］。
从流体机械的角度看，流体机械的反问题是当今流体力学领域的难题之一。
因此现有的设计基本采用流体力学的正问题设计，即先由工程设计得到流道结构，确定流动的初始条件和边界条件，再对流场进行校核。
根据校核结果对流道结构进行调整后再次校核，如此循环直到得到较优的结果。
这表明所建立的模型应是一个循环迭代逐步求精的闭环系统。
随着成组技术的广泛应用，泵设计制造正趋向于模块化，以提高零件(组件)通用性和重用性，从而降低设计制造成本，保证产品质量。
而面向对象的建模思想正好符合模块化的需要。
这表明所建立的模型应是一个面向对象的系统。
3原理方案设计模型基于以上分析，在本文所提出的原理方案设计模型中，整个设计进程是在面向对象的设计模型的基础上融合了逐步求精模型闭环设计思想而建立的，在功能分解中采用了FBS方法。
具体模型描述如图2所示：图2 原理方案设计模型结构图在模型中各个模块的具体功能为：3.1设计模型S设计模型S表示要设计的目标对象，它可以由一个或几个设计对象组成，其中包括设计实体对象(E0)和设计关系对象(R0)，其中实体对象可以是功能实体或结构实体。
即：S={［E01，E02，…，E0n］，［E01，E02，…，E0m］} 因为每个设计要求一般有若干个可选择的模型与之相匹配，并在设计过程中不断迭代更新，这里用SKG来表示设计模型K的第G代模型，则有：SKG={［E01K，E02K，…，E0nK］G，［R01K，R02K，…，E0mK］G}3.2设计算法A设计算法A为针对某一设计模型SKG，根据要求和约束(R&C)以及知识库中与本领域的专家知识，在模型库中搜索与其匹配的设计对象，创建该设计对象的一个实例Oi并将其添加到设计模型SKG中，若无匹配的设计对象，则基于知识推理创建一个新的满足要求的对象。
评价算法还对设计模型进行评价测试，对不满足要求和约束部分进行修改。
3.3要求和约束R & C在产品需求建模辅助工具系统［7］的辅助下，通过对当前设计模型需求信息的获取、拓展和分析所得到的要求和约束R&C；对设计模型的要求、存在的条件以及其重要性的权重。
最后形成一系列的功能需求{Ro.p}，Ro.p为功能需求O 的属性P。
3.4设计实体对象E0设计实体对象E0i与要求与约束中的Ri相匹配。
