The Hot Water Dispenser is shipped, from the factory, with the Heater Switch in the "OFF" position. DO NOT turn the heater switch ON until the unit is primed with water. The heater switch is located at the lower back of the unit.WATER INLET CONNECTION :The Hot Water Dispenser is to be installed to comply with all applicable Federal, State and Local plumbing codes. Furthermore, a quick disconnect or enough extra coiled tubing, (at least 2 times the depth of the machine) should be installed, so that the unit can be moved for proper cleaning underneath. It is recommended that an approved back flow prevention device, such as a double check valve, and a shut-off valve should be installed between the Hot Water Dispenser and incoming water supply.START - UP PROCEDURE:CAUTION: MAKE SURE THE HEATER SWITCH , LOCATED AT THE LOWER BACK OF THE UNIT, IS IN THE OFF POSITION.1. Connect a ¼" diameter copper waterline to the ¼" flare water inlet.2. Open the water shut-off valve and check connections for leaks. DO NOT over-tighten.3. Plug in the Hot Water Dispenser into a dedicated power supply outlet.4. Activate the Power Switch (front of unit) the water tank will begin to fill, providing the water connection is open. The tank will fill in approximately 3-4 minutes.5. After the tank has filled, activate the Heater Switch (toggle up, lower back of unit). Depending on the model selected, it will take approximately 15-25 minutes for the water to heat to operating temperature.NOTE: This procedure is for initial start - up only; however, steps 4 and 5 must be repeated should the tank be completely drained. Steps 1 thru 5 must be repeated should the machine be drained, disconnected and reinstalled in a new location.THERMOSTAT ADJUSTMENT:Remove the two (2) screws from the top cover and remove cover. The thermostat, will be visible. First, adjust the thermostat by turning the thermostat knob either clockwise to raise the temperature, or counter clockwise to lower the temperature. If further adjustment is required, remove knob, turn the adjustment screw, located in the center of the thermostat shaft, counter clockwise to increase the temperature and clockwise to decrease the temperature.Unit should be set to approximately 203°F.WARNING: Always disconnect HWD from power supply before repairing or replacing any internal components.Hot Water Dispenser - HWD2Tomlinson faucet Manual dispenseElectrical SpecificationsMODEL NOWATTSVOLTSPHASE & CYCLESPOWER CORD (included)RECEPTACLEOperationalMODEL NOINITIAL HEAT-UP TIMEBURST CAPACITYRECOVERYGALLONS PER HOURTANK CAPACITYHWD21700120 1 PH. 50/60 Hz P5-15R5-1520-25 Min 1.5 Gals 10-15 Min 4.5 2.8 GalHWD2Heat-up time and Dispense rate based on Inlet water temperature at 68°F and Dispense water temperature range 165°F to 200°F30002401 PH. 50/60 HzP6-15R6-1515-20 Min5-10 Min8.02.0 GalsVOLTS120 (1.7 KW)240 (3.0 KW)Water ConnectionWater pressure: 20 - 90 PSI (69 - 621 KPA) Supplied with ¼ OD male flare fittingExport units add "X" to Model No.Specify Voltage and type of line cord required.Hot Water Dispenser - HWD3Tomlinson faucet Manual dispenseElectrical SpecificationsMODEL NOWATTSVOLTSPHASE & CYCLESPOWER CORD (included)RECEPTACLEOperationalMODEL NOINITIAL HEAT-UP TIMEBURST CAPACITYRECOVERYGALLONS PER HOURTANK CAPACITYHWD31700120 1 PH. 50/60 Hz P5-15R5-1520-25 Min 1.5 Gals 10-15 Min 4.5 2.8 GalHWD3Heat-up time and Dispense rate based on Inlet water temperature at 68°F and Dispense water temperature range 165°F to 200°F30002401 PH. 50/60 HzP6-15R6-1515-20 Min5-10 Min8.02.0 GalsVOLTS120 (1.7 KW)240 (3.0 KW)Water ConnectionWater pressure: 20 - 90 PSI (69 - 621 KPA) Supplied with ¼ OD male flare fittingExport units add "X" to Model No.Specify Voltage and type of line cord required.23.524.39.812.09.30.77.01.3IMPORTANT- BEFORE REMOVING TOP PANEL -DISCONNECT POWER REMOVE BOTTOM PANELAND DRAIN TANKHot Water Dispenser - HWD5Tomlinson faucet Manual dispense29.029.815.312.09.30.77.0Electrical SpecificationsMODEL NOWATTSVOLTSPHASE & CYCLESRECEPTACLEOperationalMODEL NOINITIAL HEAT-UP TIMEBURST CAPACITYRECOVERYGALLONS PER HOURTANK CAPACITYHWD51700120 1 PH. 50/60 Hz P5-15R5-1530-45 Min 2.0 Gals 20-25 Min 5.0 5.0 GalHWD5Heat-up time and Dispense rate based on Inlet water temperature at 68°F and Dispense water temperature range 165°F to 200°F3000240 1 PH. 50/60 Hz P6-15R6-1520-25 Min 15-20 Min 9.03.0 Gals VOLTS120 (1.7 KW)240 (3.0 KW) 1.360002401 PH. 50/60 HzP6-30R6-3015-20 Min10-15 Min14.04.0 Gals240 (6.0 KW)Water ConnectionWater pressure: 20 - 90 PSI (69 - 621 KPA) Supplied with ¼ OD male flare fittingExport units add "X" to Model No.Specify Voltage and type of line cord required.POWER CORD (included)IMPORTANT- BEFORE REMOVING TOP PANEL -DISCONNECT POWER REMOVE BOTTOM PANELAND DRAIN TANKHEATER ELEMENT, 240V 3000W THERMOSTAT HEATER ELEMENT, 120V 1700W 1113149101HI-LIMIT 220° CUTOUT SILICONE SEAL 12mm (0.466 I.D.)LEVEL CONTROL PROBE28763L532A G267A G266A L573A K402Q M461A 1617151819WATER INLET VALVE, 120V 12L462A 20212254232425FLOAT SWITCHL499A SILICONE HOSE 3/8ID x 16" LG M857A PILOT LIGHT "HEATING"C165A POWER SWITCH L155A PILOT LIGHT "READY"C072A TEACH-ME TIMERL576A SILICONE HOSE 3/8ID x 16" LG M857A DRIP TRAY PANSA72ADRIP TRAY GRILLSA73A CONTACTOR, 2 POLE 30/40 AMP, 120V B177A SILICONE HOSE 3/8ID x 16" LG M857A LEVEL CONTROL L566A "STOP" SWITCH PB L584A "MANUAL" SWITCH PB L584A "DECANTER" SWITCH PB L584A "CUP" SWITCH PB L584A "HEATER" SWITCHL069A POWER CORD 120VC032A731011121314181716715232425PROGRAMMABLE TIMER "TEACH ME" ADJUSTMENTSThis timer can be programmed from the push buttons to dispense different volumes of hot water.

May also be referred to as “suction lift”. The atmospheric pressure of 14.7 psi at sea level limits suction head lift to less than approximately 26 feet for any pump.Discharge Head is the vertical distance between the pump’s discharge port and the point of discharge, which is the liquid surface if the hose is submerged or pumping into the bottom of a tank.Total Head is the sum of the suction head value plus the discharge head value.As water pumping height increases, pump output decreases. The length, type, and size of the suction and discharge hoses can also significantly affect pump output. It is important for the suction operation to be the shorter part of the total pumping action. This will decrease the priming time and improve pump performance by increasing the discharge head.Suction head is a maximum of 25 feet and discharge head should be a maximum of 81 feet. Total head can not be more than 106 feet as shown on next page.Move Water Pump to Safe Operating Location For best pump performance, locate the pump on a flat, level surface as close as possible to the water to be pumped. Secure water pump to avoid tipover. Use hoses that are no longer than necessary.IMPORTANT: Direct open end of discharge hose away from home, electrical devices or anything not desired to get wet.operation15Prime the Water Pump 1. Remove priming plug from top of pump.2. Fill pump with clean, clear water up to top of discharge outlet.3. Replace priming plug.operation16Locate Strainer Basket Into Water Source Place strainer basket into water to be pumped. Basket must be fully immersed.operation17Starting the Water Pump Use the following start instructions:1. Make sure unit is on a flat, level surface and pump chamber is primed.2. Turn fuel valve (1) to “On” position. The fuel valve handle will be starting the water pump18IMPORTANT: If excessive fuel is present in the air/fuel mixture causing a “flooded” condition, move choke lever to “Run” position and pull handle repeatedly until engine starts.7. Move choke lever to “Run” position a short distance at a time over several seconds in warm weather or minutes in cold weather. Let engine run smoothly before each change. Operate with choke in “Run” position.IMPORTANT: It may take a few minutes for water pump to begin pumping water.Pump output is controlled by adjusting engine speed. Moving the engine speed lever in the “Fast” direction will increase pump output, and moving the engine speed lever in the “Slow” direction will decrease pump output.starting the water pump19stopping the water pumpStopping the Water Pump 1.

By circulating the hot water they ensure that hot water is available instantly even at the tap furthest away from the water heater. Depending on the system design, Ecocirc®E1 pumps can service installations in a single-family house or apartment building.They conform to the requirements of the German Drinking Water Ordinance and offer effective pro-t e c t i o n against Legionella by circu-lating the drinking water.The water and energysavings make an impor-tant contribution forthe environmental pro-tection and the reduc-tion of CO2.The Ecocirc®E1 pumps are easy to install. To avoid reverse flow through the pump, a check valve should be used. In combination with a ball valve, the whole pump can be isolated quickly if service should become necessary. To facilitate installation, Ecocirc® E1 pumps are also available with integrated check valve and ball valve. Other areas of applications are solar systems, heat pumps or industrial applications.The circulators Ecocirc® E1 are the first of its kind to require only 8 Watt of power.This enormous energy saving is made possible by the combination of the spherical motor design invented by Laing and the ECM-Technology.Model E1Technical DataMotor design electronically commutatedshaftless spherical motor withpermanent magnet technology Power consumption 8 WattMax. system pressure 10 barElectrical connection 230 V, 50 HzSystem temperature - 10°C to + 110°C (non-freezing) Protection class/Insulation IP 44/FAcceptable media Domestic hot water, heating water,water/glycole mixtures*Other media on request.*check pump performance for mixtures of 20% or more glycoleCost saving chart eco circ ® E1Years1234567891029 €58 €87 €116 €145 €174 €203 €261 €290 €5010015020025030035012345678910232 €€ComparisonDomestic hot water / Sanitary pumps eco circ ® E1Electricity cost analogy chart213 €100200300400500Ecocirc E1-15/700 B with only 8 WattStandard circulating pump with 25 Watt43 €Years12345678910 171 €299 €427 €384 €341 €256 €85 €128 €68 €82 €96 €109 €123 €55 €41 €137 €27 €14 €€Energy and cost savingsThe high-efficiency pump Ecocirc ® E1 saves electricity, reduces the CO 2 emission and pays for itself. By com-paring the operating expense of a standard circulating pump with 25 Watt and the high-efficiency pump with 8 Watt, the cost savings beco-me quite obvious. The Ecocirc ® E1 cost savings are considerable over time.Compared with a standard circula-ting pump, the Ecocirc ® E1 saves68% electricity costs!Electricity cost calculation:Based on electricity costs of 0,1949 €/kWh in Germany and pump operating time of 24 hours/day and 365 days/year. Compare with your local average electricity costs in €/kWh: Belgium 0,1581; Denmark 0,2456; Finland 0,1160; France 0,1211; Greece 0,0720; Ireland 0,1490; Italy 0,2329; Luxembourg 0,1684; Netherlands 0,2130; Norway 0,1643; Poland 0,1184; Portugal 0,1500; Spain 0,1225; Sweden 0,1714; UK 0,1159; (all incl. taxes, referring to the German Federal Statistical Office, January 1st 2007)Pump housingRotor/ImpellerGasketCeramic bearing ballStator with ECM-TechnologyThe spherical motor designEcocirc ®DHW pumps are of the spherical motor pumpdesign. The only moving part of this pump type is a spheri-cal rotor/impeller unit which is suspended on an extremely wear resistant ceramic ball. Shaft seals or conventional bearing bushings with a shaft have been eliminated. The only self realigning bearing in the small pump market has many advantages:The suspension on a ball eliminates any bearing play – even after years of use. The pump therefore will operate quietly for years.The bearing is self-realigning. It is automatically lubricated and cooled by the pumped media (wet rotor pump). Ecocirc ®pumps are normally maintenance free.The rotor is magnetically centered on the bearing and therefore can tilt to avoid blocking by small dirt particles. Even after a long time of shut-off a safe start-up is virtually guaranteed.DesignDomestic hot water / Sanitary pumps eco circ ® E1The pump can be cleaned easily with typical household clea-ner in the unlikely case of scale deposits.Integrated, stepless scale protection thermostats are optio-nal. These thermostats are used to set a water temperature where the pump shuts off. This also results in further elec-tricity savings.Energy Efficiency due to ECM-Technology(electronic commutation with permanent magnetic rotor)The circulating pumps Ecocirc ® E1 are high efficiency pumps. ECM-Technology results in significant energy savings with the same performance:The basis for the higher efficiency is the permanent magnet rotor . The magnetic field required in the rotor does not have to be created while incurring losses, but it is permanently there. A microprocessor installed in the pump creates a rotating magnetic field with variable frequency in the stator coils (electronic commutation), which turns the rotor . The starting torque, and therefore the blockage resistance, when compared with standard circulators, is significantly increased, too.eco circeco circ ® E1 with integrated check and ball valveeco circ ® E1Replacement motors for models E1eco circ® E1 Accessories, components and spare partsPump curve and power consumption eco circ ® E1Pump curve E1-13/100 B Power consumption E1-13/100 BPump curve E1-15/700 B Power consumption E1-15/700 B0,00,20,40,60,81,01,21,41,602004006008001000120008162432Flow rate (l/h)P u m p h e a d (m )P o w e r c o n s u m p t i o n (W )1m = 10 kPa = 100 mbarU n e qu a l l e d e c o n o m i c a l l y !O nl y 8 W a t t !Laing GmbH · Systeme für Wärmetechnik · Klingelbrunnenweg 4 · 71686 Remseck · GermanyPhone: +49 (0) 7146/93-0 · Fax: +49 (0) 7146/93-33 · E-Mail: info@laing.de · Internet: ing.de20082007 S u b j e c t t o c h a n g e w i t h o u t n o t i c e .

火力发电厂暖风器疏水泵可靠性

火力发电厂暖风器疏水泵可靠性发布时间：2022-07-28T02:00:52.610Z 来源：《当代电力文化》2022年6期作者：卿鹏[导读] 暖风器疏水泵属于火力发电厂之中应用的最主要设备，应用暖风器过程中卿鹏四川广安发电有限责任公司四川省广安市 638001摘要：暖风器疏水泵属于火力发电厂之中应用的最主要设备，应用暖风器过程中，为降低工质，缩减热量损失，必须对暖风器的疏水进行回收干预。

当前，疏水泵的应用，可以有效将暖风器疏水向一级低压加热器之中输送，最典型的布置形式为疏水泵→除氧器形式，其需要进行调节单元、水位变送器、疏水泵、低位水箱及再循环调节阀设备的设置，由于控制逻辑十分复杂，且设备工作环境相对较差，所以疏水泵汽蚀、水位控制失灵及暖风器泄露故障的发生率将直接提升，所以本文就火力发电厂暖风器疏水泵可靠性展开论述分析。

关键词：活力发电厂；暖风器；疏水泵火力发电厂之中，锅炉暖风器疏水泵属于最重要的组成设备，本文就疏水泵无法正常运转的因素进行研究，应用更换泵的转子部件的形式，对疏水泵进行全方位的改进，重新依据需求进行新叶轮的参数设计，对轴部分进行加粗，并促进材料强度的提升，以盘根密封形式改变机械密封方法，对装配工艺措施进行优化，调整运行形式，与此同时，使其性能曲线逐渐向下部位倾斜，改进以后严格对其进行测试，其可对疏水泵安全稳定运转情况进行优化，实现节能节水的效用，促进经济效益的增长。

一、疏水泵工作异常原因（一）设备选型异常，裕量较大火力发电厂工作中，分析其运行数据，其运行中，实际流量大都为每小时5-20立方米，120米为扬程，由于疏水泵大都为单级单吸单蜗壳式的离心泵，其长期运行过程中，极易存在以下问题：第一，导致疏水泵压力脉动或者旋转失速，产生串轴和振动幅度提升等问题，影响机械的密封性，也可能导致疏水泵频繁损坏问题的形成。

第二，轴向推力水平提升，相对于设计工况来说，其增加约26%，轴承极易发生热损坏。

疏水泵

长沙自平衡多级泵厂家宏力水泵整理疏水泵概述：疏水泵供输送清水及物理化学性质类似于水的液体之用。

该泵扬程为H：134米，流量Q：155m3/h。

液体的最高温度不得超过80℃，广泛应用于矿山排水、工厂及城市给水之用。

使用温度T：80℃+80℃。

疏水泵产品结构说明疏水泵为多级分段式，其吸入口位于进水段上，成水平方向，吐出口在水段上垂直向上，其扬程可根据使用需要而增减水泵级数。

疏水泵装配良好与否，对性能影响关系很大，尤其是各个叶轮的口出与导翼的进出中心，其中稍有偏差即将使水泵的流量减少，扬程降低效率差，故在检修装配时务必注意。

疏水泵主要零件有:进水段、中段、出水段、叶轮、导翼挡板、出水段导翼、轴、密封环、平衡环、轴套、尾盖及轴承体。

进水段、中段、导叶挡板、出水段导翼、出水段及尾盖均为铸铁制成，共同形成泵的工作室。

叶轮为优质铸铁制成，内有叶片，液体沿轴向单侧进入，由于叶轮前后受压不等，必然存在轴向力，此轴向力由平衡盘来承担，叶轮制造时经静平衡试验。

轴为优质炭素钢制成，中间装有叶轮，用键、轴套及轴套螺母固定在轴上。

轴的一端装联轴器部件，与电机直接连接。

密封环为铸铁制成，防止水泵高压水漏回进水部分，分别固定在进水段与中段之上，为易损件，磨损后可用备件更换。

平衡环为铸铁制成，固定在出水段上，它与平衡共同组成平衡装置。

平衡盘为耐磨铸铁制成，装在轴上，位于出水段与尾盖之间，平衡轴向力。

轴套为铸铁制成，位于填料室处，作固定叶轮和保护泵轴入用，为易损件，磨损后可用备件更换。

轴承是单列向心球轴承，采用钙基润滑脂润滑。

填料起密封作用，防止空气进入和大量液体漏出，填料密封由进水段和尾盖上的填料室，填料压盖，填料环及填料等组成，少量高压水流入填料室中起水封作用。

填料的松紧程度必须适当，不可太紧亦不可太松，以液体能一滴一滴的渗出为准。

如果填料太紧，轴套容易发热，同时耗费功率。

填料太松，由于液体流失要降低水泵的效率。

暖风器疏水泵结构和工作原理

暖风器疏水泵结构和工作原理暖风器疏水泵，名字听起来有点高大上，但其实说白了，它就是一种为暖风器提供“动力”和“安全”保障的小帮手。

说到这，可能有朋友要问，暖风器不就是我们冬天取暖的设备吗？这疏水泵到底是什么鬼？别急，我这就给你扒一扒它的结构和工作原理，让你一看就懂。

暖风器疏水泵的结构，简单来说，就是由几大部分组成。

它有一个泵体，这个泵体可不是你随便买个塑料瓶就能代替的哦。

泵体通常是铸铁或者不锈钢，耐高温耐腐蚀，坚固得很。

泵内有个“心脏”——这就是水泵的工作部分，负责将积水排出。

你想啊，暖风器在工作的时候，难免会有水蒸气凝结成水滴，这些水滴得不到及时排出，不仅浪费能源，还可能腐蚀设备。

这时候，疏水泵就派上用场了，它帮助把水分迅速排掉，保证暖风器的正常运行。

说到工作原理，大家可能觉得很复杂，但其实它的工作方式挺简单的。

我们知道，水蒸气会在温差较大的情况下凝结成水滴，对吧？暖风器也是如此。

在暖风器开始工作时，温度升高，空气中的水蒸气变成液态水，这些水滴就会积累在暖风器的管道和底部。

而这时，疏水泵就开始“忙碌”了。

它通过一个浮球装置感应水位的变化。

当水位过高时，浮球就会升起来，触发开关，开始工作。

水泵启动后，便会把积水排出，确保暖风器内部保持干燥。

如果水位下降，浮球又会下降，水泵自动停止工作。

这就是所谓的“自动化”，听起来是不是挺聪明的？这疏水泵啊，真的是暖风器的得力助手。

没有它，暖风器就像是缺了“心脏”的人，根本没法正常工作。

而且啊，疏水泵不止是排水这么简单。

它的作用，还包括了防止管道生锈、减少设备的损耗。

你要知道，设备工作时要持续加热，积水没有及时排除的话，水滴蒸发出来的热量就会白白浪费掉。

就像你在家里开着暖气，但如果空气中湿气太重，暖气根本暖不到你想要的效果。

疏水泵的作用就是把这些积水给排掉，让暖风器能更高效地工作。

疏水泵也会出现小问题，像是被堵塞了，或者长时间没维护，导致排水不畅。

这样一来，暖风器的效率就会下降，甚至出现故障，严重的时候还会烧坏电机。

FunctionTCNThe partial flow for cooling the motor and lubricating the slide bearings is branched off at the periphery of the impeller and, after having passed through the motor, is carried back again through the hollow shaft to the suction side of the impeller.TCNF [liquefied gas design]The partial flow for cooling the motor and lubricating the slide bearings will be branched off at the periphery of the impeller and, after having passed through the motor sealing cover, is carried back again to the pressure line via a con-necting line. An auxiliary impeller serves to overcome the hydraulic losses encountered along the way. The connection line serves at the same time to vent the pump and motor.TCAMThe flow rate is delivered through the impellers and diffusers arranged one behind the other to the pressure nozzles and in this way an increase in pressure is achieved depending on the number of stages. The partial flow for cooling the motor and lubrication the slide bearings is tapped off on pressure side after the last impeller and after flowing through the motor is lead out again through the hollow shaft between the stages.TCAMF [liquefied gas design]The flow rate is delivered through the impellers and diffusers arranged one behind the other to the pressure nozzles and in this way an increase in pressure is achieved depending on the number of stages.

At the same time, the connection line serves to vent the pump and motor.Model series TCN / TCAM Application sectorThanks to the EU guideline 96/61/EC (so-called IPPC guide-line) as well as the Federal Immission Protection Lawand the TA-Luft, emissions from pumps have been severely restricted. Today, as a consequence of these restricted regulations in environmental protection for toxic, explosive and liquefied gases, there has been an increasing tendency not to provide vessels and vessel drains with a lateral outlet or bottom outlet, i.e. with a drain nozzle installed in the range of the bottom.Application sectors are tank farms, terminals chemical and off-shore plants, gas accumulators, and industrial plants. In addition to the optimum design for TCN and TCAM pumps there are various mounting options.TCN / TCAMFor the delivery of aggressive, toxic, explosive, precious, inflammable, radioactive and slightly volatile fluids e.g. sulphuric acid, nitric acid, hydrofluoric acid, hydrocyanic acid, ethanoic acid, formic acid, NaOH, KOH, D2O, solvent, etc.TCNF / TCAMFLiquid gases, e.g. ammonia, freone, carbon dioxide, amines, propane, butane, vinyl chloride, ethylene oxide, chlorine, phosgene, propylene, carbon bisulphide, hydrocarbon, diphenyl (> 250 °C) etc.Application rangesTCN / TCNF: –160 °C to +250 °CTCAM / TCAMF: –160 °C to +250 °CCanned motorsPower: u p to 300 kW at 1450 rpm [50 Hz]up to 400 kW at 2900 rpm [50 Hz]up to 336 kW at 1750 rpm [60 Hz]up to 448 kW at 3500 rpm [60 Hz] Operation: S1 to S10Voltage: 400 / 690 V(special tensions possible)Heat class: H – 180C – 220 / C – 400Frequency: 50 or 60 Hz(plus frequency converter operationon request)Protections: motor IP 68terminal box IP 65Motor protection: t hermistor e.g.KL 180 (for H-winding)PT 100 (for C-winding)Explosion protectionaccording to EC design test certificate in line with Directive 94/9/EG ATEX II 2 G EEx de II C T1 to T6 / II 2 G ck II C TxDocumentationDigital standard documents (CD-ROM) adapted to CE requirements include:sectional drawing■■dimensional drawing■■EC conformity declaration■■operating instructions■■Inspections and guaranteesStandard inspectionsHydraulic inspection:each pump is subject to a test run and the operating■■point is guaranteed according to ISO 9906 – class 2 (5 measuring points)pressure test■■axial thrust measurement■■leak test■■Additional inspectionsThe following inspections can be carried out and certified against additional price (e.g. NPSH test, Helium leakage test, vibration test, ultrasonic test, PMI test). Any further inspec-tions and tests are according to the technical specification. The guarantees are effected according to the valid conditions of supply.Application and insertionFunctional principleTechnical specificationAdvantages of hermetically sealed motor-driven submersible pumpsThe hydraulic part is arranged above close to the vessel bot-tom. The pressure line is placed in parallel to the pump drive shaft via manhole door to the outside. The impeller is arranged at the shaft which is fixed by medium-lubricated guide bear-ings. Depending on the immersion depth several bearings will be required. The following reference value will apply: accord-ing to the pump size, one guide bearing per 1,2 m to 1,6 m is required. The bearings are installed in a support pipe that is fixed to the manhole door. The sealing to the atmosphere is effected by using a mechanical seal. The conventional drive motor is installed outside the vessel and can be used for every protection type according to the explosion requirements.The basic and outer construction of a conventional pump with mechanical seal can be compared with the design of a submersible pump with magnetic drive. The difference of sealing to the atmosphere is the containment shell of the magnetic coupling that is directly installed to the pump component. The containment shell ensures an absolute leakage-free pump operation and can also be installed onthe outside of the vessel.Because of that, the drive shaft of this construction type is not medium-lubricated but operates in a dry place. The bearings used are prelubricated roller bearings which are placed in a support tube under dry conditions. The cable passage at the manhole door is sealed by a mechanical seal. According to the depth of assembly several bearings need to be installed here as well. Conventional electric motors can also be used here as a drive.When installing canned motor pumps the drive shaft having a length according the immersion depth is no longerneeded. The rotating parts of the pump shaft are placed in the canned motor pump and are therefore extremely short. The pump is fixed to a support pipe which is arranged at the manhole door. The single task of the support pipe is to carry the pump and to lead the cables to the outside. Medium-lubricated guide bearings or prelubricated roller bearings are not necessary since the usually used long drive shaft is not required for operational reasons. Therefore, in case of vertical submersible pumps with canned motor, the length of the drive shaft is irrespective of the immersion depth.Bearing arrangementThe bearing in hermetically designed pumps must be located and immersed in the operating liquid. Therefore, in most cases, only the use of hydrodynamic slide bearings is required. The correct operating method ensures the advantage that no contact may be created between the bearing lining. Thus, they are constantly running free from wear and maintenance. Service life of 8 to 10 years can be easily achieved by using HERMETIC pumps.The almost universal bearing combination based on tungsten carbide (W5) and silicon carbide (SiC30) has to be proved to be the best choice. These combinations consist of metallic shaft sleeves made of stainless steel (1.4571) and coatedby tungsten carbide according to the “High Velocity Oxygen Fuel Procedure“. Furthermore, they consist of a firm bearing bush made of ceramic material (SiC30) that is surrounded by a sleeve made of stainless steel. SiC30 is a mixed material of silicon carbide and graphite, combining the product advantages of both materials. Conditions of mixed friction, as they may arise for example during start-up and stopping phase of pumps, can be easily handled with SiC30. Moreover, this material is deemed to be thermal shock resistant (high resistance against changes in temperature), as well as chemically stable and blister resistant (no formation of bubbles at material surface) and abrasion resistant.MonitoringThe most part of HERMETIC pumps are designed according to explosion protection requirements. The pumps comply with the requirements of the electrical as well as mechanical explosion protection.Level monitoringOn condition that the rotor cavity as part of the process system is steadily filled with liquid, no explosive atmosphere may arise. In this case, no accepted explosion protection is required for the rotor cavity. If the operator is not able to guarantee for a steady filling, it is necessary to install level monitoring devices.Temperature monitoringThe observance of the temperature class and the maximum admissible surface temperature of the canned motor,respectively, is ensured via thermistor in the stator winding and/or via a measuring point on the bearing cover (liquid temperature).Monitoring of rotor positionThe axial thrust balancing is mainly influenced by the operating method of the pump, plant conditions and by various physical data of the liquid to be conveyed. For early detection of the source of errors, it is recommended to install a rotor-position-monitoring device. This electronic protective gear monitors the axial shaft clearance of the rotor, as well as its direction of rotation during operation in a hermetic and seal-less way. Together with the level and temperature monitoring, an effective and automatic early detection of failures may be achieved.Bearing arrangement and monitoring systemsMounting systemsThe HERMETIC canned motor submersible pump provides the optimum solution for difficult installations. Essentially there are two different installations in the tank and in the vessel:a) direct placing in the tank (figure 1)b) i nstallation of the pump with the opportunity to separate the pump from the liquid in the vessel (figure 2)Installation vessel pumpThe direct placing of the submersible pump in the tank is recommended for small container volumes, e.g. for NPSHA improvement in vessel loading/unloading stations.Installation pump with the opportunity to separate the pump from the liquid in the vesselIf it is necessary that the submersible pump with a filled tank is removed and reinstalled during a revision, the instal-lation when the pump is separate from the liquid has proved to be the best optimum solution.In this system, there is a shut-off valve close to the tank bottom, which can be operated with a gear or with a pressure medium run system.The delivery medium can be pushed back into the tank by inertisation. After closing of the valve and releasing the pressure the submersible pump can be removed or installed without emptying the vessel.5 32-2006 32-2507 40-1608 40-2009 40-25014 50-31515 65-16016 65-20017 65-25018 65-31523 100-25024 100-3155 32-2006 32-2507 40-1608 40-2009 40-25014 50-31515 65-16016 65-20017 65-25018 65-31523 100-25024 100-31525 100-40026 125-25027 125-31532 150-50033 200-25034 200-31535 200-40036 200-50041 300-5005 32-2006 32-2507 40-1608 40-2009 40-25014 50-31515 65-16016 65-20017 65-25018 65-31523 100-25024 100-3155 32-2006 32-2507 40-1608 40-2009 40-25014 50-31515 65-16016 65-20017 65-25018 65-31523 100-25024 100-31525 100-40026 125-25027 125-31532 150-50033 200-25034 200-31535 200-40036 200-50041 300-500Convincing service.Important features are readiness, mobility, flexibility, availability and reliability.
