The Q400EM is a high-performance, research-grade thermomechanical analyzer (TMA), with unmatched flexibility in operating modes, test probes, fixtures, and available signals. For standard TMA applications, the Q400 delivers the same performance and reliability. It is ideal f or research, teaching, and quality control applications, with perf ormance equivalent to competitive research models.Temperature Range (max)-150 to 1,000°C-150 to 1,000°CTemperature Precision + /- 1°C+ /- 1°CFurnace Cool Down Time <10 min from 600°C to 50°C <10 min from 600°C to 50°C (air cooling)Maximum Sample Size - solid 26 mm (L) x 10 mm (D)26 mm (L) x 10 mm (D)Maximum Sample Size - film/fiber 26 mm (L) x 0.5 mm (T)26 mm (L) x 0.5 mm (T)x 4.7 mm (W)x 4.7 mm (W)Measurement Precision +/- 0.1 %+/- 0.1 %Sensitivity15 nm15 nmDynamic Baseline Drift <1 µm (-100 to 500°C)<1 µm (-100 to 500°C)Force Range 0.001 to 1 N 0.001 to 1 N Force Resolution 0.001 N 0.001 N Frequency 0.01 to 2 Hz Not Available Mass Flow Control Optional Optional AtmosphereInert, Oxidizing, Inert, Oxidizing, (static or controlled flow)or Reactive Gasesor Reactive GasesNote: The Q400 can be field upgraded to the Q400EM.Operational Modes Standard Included Included Stress/Strain Included Not Available CreepIncluded Not Available Stress Relaxation Included Not Available Dynamic TMA (DTMA)IncludedNot AvailableModulated TMA ™(MTMA ™) Included Not Available1The Q400 features a rugged and reliable furnace. Its customized electronics provide excellent heating rate control and rapid response over a wide temperature range. Furnace raising and lowering is soft-ware controlled. The design ensures long life and performance consistency. The excellent heating rate control provides for superior baseline stability and improved sensitivity, while the rapid response permits Modulated TMA™operation. Furnace movementprovides operational convenience, and easy access to the sample chamber.2Located in the furnace core, the easily accessed chamber provides complete temperature and atmosphere control for sample analysis. Purge gas regulation is provided by an optional digital mass flow controller. These include enhanced data quality, ease-of-use, and productivity. The open design simplifies installation of available probes (see Modes of Deformation), sample mounting, and thermocouple placement. Data precision is enhanced by mass flow control of the purge gas.2 13Force Motor A non-contact motor provides aprecisely controlled, friction-free, calibrated force to the sample via the measurement probe or fixture. The force is programmable from 0.001 to 1 N, and can be increased to 2 N by addition of weights to a special tray. A precision sine wave generator provides a set of ten individual frequencies for use in dynamic experiments. Benefits:The motor smoothly generates the accurate and precise static, ramped, or oscillatory dynamic force necessary for quality measurementsin all modes of operation. The choice of frequencies allows optimization of dynamic TMA (DTMA) experiments in compression, 3-point bending, or tension modes of deformation.4Linear Variable Differential Transducer The heart of the Q400TMA sample measurement system is the precision, moveable-core, linear variable differential transducer (LVDT). Benefits:It generates an accurate output signal that is directly proportional to a sample dimension change. Its precise and reliable response over a wide temperature range (–150 to 1,000°C) makes for reproducible TMA results. Its location below the furnace protects it from unwanted temperature effects and ensures stable baseline performance.3421Expansion measurements determine a material’scoefficient of thermal expansion (CTE), glass transi-tion temperature (Tg), and compression modulus.A flat-tipped standard expansion probe (Figure 1)is placed on the sample (a small static force may be applied), and the sample is subjected to a temperature program. Probe movement records sample expansion or contraction. This mode is used with most solid samples. The larger surface area of the macro-expansion probe (Figure 2)better facilitates analysis of soft or irregular samples, powders, and filmsP ENETRATIONPenetration measurements use an extended tip probeto focus the drive force on a small area of the samplesurface (Figure 3). This provides precise measurementof Tg, softening, and melting behavior. It is valuablefor characterizing coatings without their removal froma substrate. The probe operates like the expansionprobe, but under a larger applied force. The hemi-spherical probe (Figure 4)is an alternate penetrationprobe for softening point measurements in solids.C OMPRESSIONIn this mode, the sample is subjected to either a static, linear ramp, or dynamic oscillatory force, while under a defined temperature program, and atmosphere. Sample displacement (strain) is recorded by either expansion / penetration experiments to measure intrinsic material properties, or dynamic tests to determine viscoelastic parameters (DTMA), to detect thermal events, and to separate overlapping transitions (MTMA™).Figure 2Figure 43-P OINT B ENDINGIn this bending deformation (also known as flexure), the sample is supported at both ends on a two-point, quartz anvil atop the stage (Figure 7). A fixed static force is applied vertically to the sample at its center, via a wedge-shaped, quartz probe. Material properties are determined from the force and the measured probe deflection. This mode is considered to represent “pure” deformation, since clamp-ing effects are eliminated. It is primarily used to determine bending properties of stiff materials (e.g., composites), and for distortion temperature measurements.Dynamic (DTMA) measurements are also available with the Q400EM, where aspecial low-friction metallic anvil replaces the quartz version.S PECIALTY P ROBE / F IXTURE K ITSAdditional sample measurement probes and fixtures are available for use with both the Q400 and Q400EM in specialty TMA applications. These include:Dilatometer Probe Kit –for use in volume expansion coefficient measurementsParallel Plate Rheometer –for the measurement of low shear viscosity of materials (10 to 107Pa.s range)under a fixed static force.The expansion, macro-expansion, and penetration probes are supplied with the Q400. These probes, plus the flexure probe, and the low-friction bending fixture, are included with the Q400EM module. Data analysis programs relevant to each of the measurements described are provided in our Thermal Advantage ™for Q Series ™software.T ENSIONTension studies of the stress/strain properties of films and fibers are performed using a Film/Fiber probe assembly (Figure 5). An alignment fixture (Figure 6)permits secure, and reproducible, sample positioning in the clamps. The clamped sample is placed in tension between the fixed and moveable sections of the probe assembly. Application of a fixed force is used to generate stress/strainand modulus information. Additionalmeasurements include Tg, softening temperatures, cure, and cross-link density. Dynamic tests (e.g. DTMA,MTMA™) in tension can be performed to determine viscoelastic parameters (e.g., E |, E ||, tan δ), and to separate overlapping transitions.Figure 6Figure 7TMA measures material deformation under controlled conditions of force, atmosphere, time, and temperature. Force can be applied in compression, flexure, or tension modes using probes previously described. TMA measures intrinsic material properties (e.g., expansion coefficient, glass transition temperature,Young’s modulus), plus processing / product performance parameters (e.g., softening points). These measure-ments have wide applicability, and can be performed by the Q400/Q400EM.TMA can also measure polymer viscoelastic properties using transient (e.g., creep, stress relaxation)or dynamic tests. These require the Q400EM module. In creep, a known stress is applied to the sample, and its deformation is monitored. After a period, the stress is removed, and strain recovery is recorded. In stress relaxation, a fixed strain is applied, and stress decay is monitored.In Dynamic TMA (DTMA), a known sinusoidal stress and linear temperature ramp are applied to the sample, and the resulting sinusoidal strain, and sine wave phase difference (δ), are measured . From this data, storage modulus (E |), loss modulus (E ||), and tan δ(E ||/E |) are calculated as functions of temperature, time, or stress.In Modulated TMA ™(MTMA ™), the sample experiences the combined effects of a linear ramp, and a sinusoidal temperature of fixed amplitude and period . The net signals, after Fourier transformation of the raw data, are total displacement and change in thermal expansion coefficient. Both can be resolved into their reversing and non-reversing component signals.The reversing signals contain events attributable to dimension changes, and are useful in detecting related events (e.g., Tg). The non-reversing signals contain events that relate to time dependent kinetic processes (e.g., stress relaxation).The Q400 and 400EM operating modes permit multiple material property measurements.The Q400 features the Standard mode, while the Q400EM additionally offers Stress/Strain,Creep, Stress Relaxation, Dynamic TMA, and Modulated ™TMA modes.Temperature (Time)Force StrainT(F o r c e )Force (Time)TFS TANDARD M ODE (Q400/Q400EM)Force is constant, and displacement is monitored undera linear temperature ramp.

Friction Analysis for Piston Ring of Seal Device in the Stirling EngineHou Shunqiang1, a,Zhang Lili2,b and Zhang Xiaoyan 3,c1 Qingdao Binhai University, Qingdao China2Shandong University of Science and Technology, Qingdao China3SAIC-GM-Wuling Automobile Co.Ltd SGMW , Liuzhou Chinaa b cKeywords: Stirling Piston ring; Dynamic seal; Friction and wear.Abstract. The friction pair of piston ring-cylinder liner for the piston ring seal device of Stirling Engine is plastic-metal friction pair, its working conditions for dry friction. So the wear resistance of the piston ring is poor, its service life is short. This paper regard integral non-backpressure piston rings group as the research object in order to reduce wear: First, establishes auto-free lubricating mechanical model to piston rings group; Then, set up the mathematical model, which to meet the requirements of the sealing performance, for friction analysis; At last, Experimental analysis in the Piston Ring Seal Device of Stirling Engine to prove that this model is correct and available. IntroductionThe opening with back pressure free lubricating piston rings is used in most piston ring seal device of Stirling Engine in domestic at present. During the working process of piston rings with opening back pressure free lubricating, the compressed medium pressure will press on the surface of piston ring’s inner column to make adhered pressure between piston ring and cylinder surface, which produce friction consumption in the process of piston rings’ reciprocating movement. However, as the piston ring of Stirling Piston works in the dry friction condition, it is easy to wear and its service life is short, besides, the sealing performance of Stirling Engine is affected by the friction character directly. This paper mainly bases on the operation condition of Stirling Engine to analyze the elements that affect the wear of piston ring and propose some measures to lengthen piston ring’s service life.Improved Sealing Structure of Stirling Engine Piston RingThe improved sealing structure of Stirling Engine piston ring is as Fig. 1. Two piston rings and two guide rings are designed on the piston. The piston ring has a slot and double loop with an inside and outside structure. Two pieces are included in the outside ring and one is the upper ring the anther one is the lower ring. The upper one is the open type one with straight incision structure. The lower one is an integrated ring with a convex at the corresponded point with upper incision. Those two rings form the ring group and make two ends adhere. The inside ring is a spring lamination made by a stainless steel belt piece and it is 10~15mm longer than inside ring’s perimeter. Curve it into a lap round to be a elastic ring when install it and then embed it into piston ring to form interference fit. The guide ring has a slot and a ring with an uninstall hole, which can help guide ring without gas pressure and only play the role of oriented support. The piston ring and guide ring are produced by the Chinese Academy of Sciences Lanzhou Institute of Chemical Physics and the compound design is made by 40% Cu+ 60% F4 filled PTFE with self lubrication and good thermal conduction. With the force analysis as Fig.2 and ignoring the affection that produced by surface roughness (W=0)betweenApiston ring and cylinder wall, the upper ring end adhered tightly with the lower ring end with influence of gas pressure. Both of the two rings have incision and convex to make these rings into a set without mutual turning. The inner perimeter and metal elastic ring of upper and lower rings hasformed interference fit and the elastic ring’s inner perimeter adheres tightly with piston ring’s slot which also forms interference fit. The inner perimeters of upper and lower rings adhere tightly with metal-made elastic ring, which forms an integrated structure and make these two ends adhere tightly, and so does the elastic ring and metal ring’s slot. In this way, the leakage path and leakage path ①①will be filled it; because of the thermal expansion effect for the upper ring’s opening, the upper ring’s external diameter adheres with cylinder wall tightly and fill the leakage path . The straight incision ④on the upper ring forms to a clearance fit with the convex on the lower ring, which makes no mutual turning between these two rings. Due to the small clearance between the two ends, some gas thatleaks from the clearance between upper ring’s openingand lower ring’s convex, leak into the clearancebetween lower ring and cylinder wall (gas cell 2and 4)to form the leakage path . The internal and external③diameters of the guide ring form interference fit with theexternal of guide ring’s slot and cylinder’s internaldiameter. However, the load-off hole is equipped on theguide ring and the guide ring does not have sealingfunction, the gas that goes through the clearancebetween guide ring and cylinder wall can not producepressure drop, and the guide ring just play the role ofguide.1-cylinder liner 2- guide ring 3-piston 4-upper piston ring 5-leakage path 6①-elastic ring 7- leakage path 8①-lower piston ring 9- leakage path 10③- leakage path ④Fig.1 the structure diagram of no-back-pressure piston ring setPiston Rings’ Friction AnalysisThe Elastic Specific Pressure Produces by Thermal Expansion.The thermal expansion of piston can produce uniform pressure to the cylinder wall (Fig. 2)Fig. 2 Loaded diagram of no-back-pressure nonmetal pistonSee the metal ring as rigid body when calculate thermal deformation.

That is to say: ()j j phd d phd ht == ββσπ02sin 2(2)Put the formula (1)into (2)to get the formula between the elastic specific pressure of piston rings, P and the working temperature T 1 :()j d T T Et P 012−=α(i =1,2,3,4) (3) The Effect from Gas Pressure to Piston Rings’ Radial Direction Specific Pressure.The high pressure sealing gas through the leakage path ③ (two places) and other seal surfaces, its pressure reduces from P1 to Pi (i=1,2,3,4) in sequence to corresponding gas cell; −m P is the average radial pressure that beard on the corresponding ring’s external diameter’s cylindrical surface and the pressure’s direction points from external to internal, besides, as the effect of thermal expansion during working hours, the elastic ring produces outward radial specific pressure P to the rings’ internal diameter. Meanwhile, as the compression when first assembling, the guide ring also produces outward radial specific pressure P k to cylinder walls. The algebraic sum of these pressures in radial direction is just the positive pressure that needed to form piston tings’ static friction.The radial elasticspecific pressure of elastic rings P k can be calculated from formula (4)[5] .()108.7−=e e e e k k D D A E P (4) The average radial pressure that beard by each external diameter’s cylindrical surface will be seenas formula (5)[6].()121+−+=m m m P P P )4,3,2,1(=m (5) The relation between average radial pressure and the sealed gas pressure 1P will be seen as formula (6)[6]. 14131211034.0,076.0,20.0,76.0P P P P P P P P ====−−−− (6) The radial specific pressure from gas to piston rings is like the following:14107.1P P P m m m ==∑=− (7)The Effect from Pistons’ Pace to Force of Sliding Friction.F f means the static friction when piston rings in the station of static and sealed, it can be calculated from formula (8).()()()11101,07.1177.1··8P T F P t D D A E d T T t E F f e e e e k j f =⎥⎥⎦⎤⎢⎢⎣⎡−−+−=αμ (8) The piston rings’ round surface and the cylinder walls form the relative sliding to produce sliding friction at sealed surface.

The measured dynamic friction in different operating conditions have been drawn curve graphs as the following Fig.3, Fig.4 and Fig.5.Conclusions(1)It can be seen from Fig.3 that if the sealed gas pressure P 1 and piston pace v are constant, the force of sliding friction F d will increase with the working temperature of piston rings and it will beμ=0.12 E =280MPa t = 1.6mm α=(10~15)×10-5 mmT 0=25℃ dj =55mm E k =193MPa A e =0.2mmD e =51.8mm t e =1.75mm P 1=0~8MPa K 1 =0.28 K 2 =247N·s/msteady at last. It is because when the working temperature increases the heat clearance of pistons’ opening will enlarge and the external diameter of piston will adhere tightly with cylinder wall. Just right now, the radial positive pressure from piston ring to the cylinder wall increase and the static friction F f aggrandizes. When the heat clearance of opening enlarges to limit, the static friction will to be maximum.(2)It can be seen from Fig.4 that if the sealed gas pressures P 1 and the working temperature T 1 are constant; when the pistons start to move its pace v is very low, however, with the increase of v the relative slip on the seal surface are severe and the radial wear quantity h =kpvt of piston ring will increase, and the frictional vibration will be severe and the sliding friction F d will be increased as well. When the radial wear quantity h of piston ring to be the maximum, the contact surface between piston ring’s external diameter and cylinder becomes very smooth and then the friction coefficient μ will decrease, the sliding friction F d will decrease with decrease of static friction. When μ becomes minimum; F f will be steady as well as sliding friction F d .(3)It can be seen from Fig.5 that if the piston pace v and the working temperature T 1 are constant, the force of sliding friction F d will decrease with the increasing of sealed gas pressure and then to be steady. It is because when P 1 increases the positive pressure N will decrease and this can be reflected from formula (8). When the seal gas in cavity became thermal equilibrium state the seal gas pressure P 1 will to be steady. The force of static friction F f will decrease to a steady state value and the sliding friction will be constant as well.F r i c t i o n /K NTemperature/.C F r i c t i o n /K NVelocity/(m/s)Fig.3 curve between sliding friction F d and sealed Fig.4 curve between sliding friction F d and working temperature T 1 when P 1=8MPa,ν=0.57m/s piston pace ν when T 1=150,℃P 1=2MPaF r i c t i o n /K N Pressure/MpaFig.5 curve between sliding friction F d and sealed gas pressure P 1 when ν=0.57m/s,T 1=150℃References [1] Jin Donghan.

胀管工艺流程及原理

胀管工艺流程及原理

胀管工艺流程及原理英文回答:Tube expansion is a process used in various industries, including manufacturing, construction, and plumbing, tojoin or seal tubes together. It involves expanding the end of a tube to fit another tube or fitting, creating a secure and leak-proof connection. The process is commonly used in HVAC systems, heat exchangers, and hydraulic systems.The tube expansion process typically involves the use of a tube expander, which is a tool designed to enlarge the diameter of the tube end. The expander is inserted into the tube, and then expanded using a hydraulic or mechanical force. This expansion creates a tight fit between the tube and the fitting, ensuring a strong connection.There are several methods used for tube expansion, including hydraulic expansion, mechanical expansion, and thermal expansion. Hydraulic expansion is the most commonmethod and involves using hydraulic pressure to expand the tube. Mechanical expansion, on the other hand, utilizes a mechanical force, such as a hammer or a mandrel, to expand the tube. Thermal expansion involves heating the tube and then expanding it while it is hot.The choice of tube expansion method depends on various factors, such as the type of tube material, the desired level of expansion, and the application requirements. Each method has its advantages and disadvantages. For example, hydraulic expansion offers precise control over the expansion process and is suitable for a wide range of tube materials. Mechanical expansion, on the other hand, is more suitable for thick-walled tubes and can provide a higher level of expansion. Thermal expansion is often used for joining dissimilar materials, as it allows for a secure bond between the materials.In addition to the method used, the tube expansion process also involves several steps. First, the tube end is prepared by removing any burrs or sharp edges. Then, the expander is inserted into the tube and expanded to thedesired diameter. The expansion is carefully controlled to avoid over-expansion or damage to the tube. Once the expansion is complete, the tube is inspected for anydefects or imperfections. Finally, the expanded tube is joined with another tube or fitting using welding, brazing, or other joining methods.Tube expansion is a critical process in many industries, as it ensures the integrity and reliability of tube connections. It allows for the efficient transfer of fluids or gases and helps to prevent leaks or failures. Theprocess requires skilled technicians who are familiar with the specific requirements of each application and canensure proper expansion and joining of the tubes.中文回答:胀管工艺是在制造、建筑和管道等多个行业中使用的一种工艺,用于连接或密封管道。

关于热胀冷缩的气球的英语作文

关于热胀冷缩的气球的英语作文

关于热胀冷缩的气球的英语作文英文回答:In the fascinating realm of physics, the phenomenon of thermal expansion and contraction plays a captivating role. It describes the change in an object's dimensions as its temperature fluctuates. As an illustration, when a balloon is exposed to varying temperatures, its volume undergoes significant alteration.Thermal expansion is a characteristic observed in all substances, including solids, liquids, and gases. It arises from the increased kinetic energy of particles at higher temperatures, leading to increased intermolecular spacing and, consequently, a larger volume. In the context of a balloon, as heat is introduced, the air molecules within the balloon gain energy and move more vigorously. This enhanced molecular motion causes the balloon's volume to expand.Conversely, when the temperature of the balloon decreases, the thermal energy of the air molecules diminishes, resulting in reduced molecular motion and closer intermolecular spacing. This contraction of the balloon's volume is attributed to the decreased kinetic energy of the air particles.The magnitude of thermal expansion, often quantified as the coefficient of thermal expansion, varies amongdifferent substances. Notably, gases exhibit a greater susceptibility to thermal expansion compared to solids and liquids. This enhanced expansivity is attributed to the weaker intermolecular forces in gases, allowing for more pronounced changes in molecular spacing.In addition to temperature fluctuations, the pressure exerted on the balloon can also influence its volume. When pressure is applied to the balloon, its volume decreases as the air molecules are forced closer together. Conversely, a decrease in pressure leads to an expansion of the balloon's volume.The interplay between temperature and pressure on the balloon's volume can be particularly intriguing. For instance, when the balloon is heated while simultaneously being squeezed, the combined effect of thermal expansion and reduced pressure can result in a complex behavior. Depending on the relative magnitudes of these opposing forces, the balloon may expand, contract, or exhibit a change in shape.Exploring the phenomenon of thermal expansion and contraction in balloons offers a captivating demonstration of fundamental physics concepts. It underscores the interplay between temperature, pressure, and volume, highlighting the dynamic nature of matter and the nuanced complexities of the physical world.中文回答:热胀冷缩的气球。

As a general rule, bulbs of expansion valves should be insulated to prevent them being affected by the ambient temperature. • Do not bend or squeeze the bulb when tightening the bulb clamp • Never quench the base with water after soldering, this may cause cracks and distort the sealing surfaces. • The screws fixing the valve body to the solder base must be tightened in diagonal sequence (torque 20 Nm). • Constructive modifications at the valve are not allowed.Superheat AdjustmentIn general the Honeywell valves should be installed with the factory setting for the used refrigerant unaltered. This superheat adjustment is calibrated for lowestsuperheating and optimum evaporator utilisation. However, should it be necessary to adjust the superheat, turn the adjusting spindle as follows:Turning clockwise = reduced refrigerant mass flow, increase of superheat Turningcounterclockwise=increased refrigerant mass flow, decrease of superheatOne turn of adjusting spindle alters superheat setting by approx. 0.3 bar. Increase of superheat setting results in a lower MOP-value and vice versa.K A T -T M X -002Type Code / Order Information (Part Programme)1.

3Instruction sheet3B SCIENTIFIC ® PHYSICSU15405 Linear thermal expansion apparatus3/03 ALF®The apparatus demonstrates the linear expansion of solid materials and allows the determination of expan-sion coefficients for copper, iron and glass.1. Safety instructions•Caution. The experimental procedure results in hot steam.•Do not touch heated rods with your fingers. Use cloths when replacing rods.•Do not subject the glass rod to mechanical stresses.2. Description, technical dataThe equipment consists of a base track with a spring clip at the left-hand end for attaching a testing rod. At a distance of 50 cm from the end there is a notch in the base strip for the pointer. The copper and iron test rods have a ring nut 65 cm from the end for placing on the pointer. The glass rod has a metal ring with a ring nut in the same place. Behind the pointer is a 0-5 cm scale. To feed in hot steam, a 10 cm long glass rod attached to a hose is provided.Dimensions:530 mm x 60 mm x 240 mm Weight:0.6 kgLength of rods:630 mm approx.Diameter of rod:8 mm approx.Length of pointer:200 mm Scale markings:mm Scale factor:1 : 503. PrincipleTo determine the linear expansion coefficient α for vari-ous materials, it is necessary to measure the expansion for a certain temperature rise ∆T . Thus the rods are heated to 100° C by means of steam and the tempera-ture difference ∆T from room temperature is calculated.The expansion is determined from the movement of the pointer d , where a pointer movement of 50 mm indicates an expansion of 1mm. The expansion coeffi-cient is determined from the extension w (scale factor 1:50) and the length of rod l between the two fixed points by means of the formula:α=⋅⋅dl w T∆4. Instructions for useAlso required for heating the rods is a vapor generator or a bunsen burner heating an Erlenmeyer flask•Attach the end of the rod without the nut to a rub-ber hose and secure in the spring clip.•Place the pointer in the notch under the scale and attach the upper end of the pointer to the rod with the ring nut.•Adjust the pointer to zero by sliding the rod.•Attach to a steam generator or an Erlenmeyer flask half-filled with water by means of the short glass rod and a hose.•Boil water. Steam flows through the test rod and heats it to approximately 100° C.1Spring clip 2Base track 3Glass rod 4Test rods 5Pointer 6Scale126543(Note: at high altitudes, water boils at slightly less than 100° C.)•When steam has been passing through the rod for about 1 minute and no more condensing steam is emerging from the end of the rod, read off the larg-est movement of the pointer.5.

浮头式换热器解读

浮头式换热器解读

浮头式冷却器E-1401设计摘要该毕业设计题目为浮头式冷却器(即浮头式换热器)E-1401设计,源于工程实际。

浮头式换热器是管壳式换热器中的一类,其管板一端固定在壳体与前端管箱之间,另一端(即浮头)可以在壳体中自由移动。

由于管束的热膨胀不受壳体的约束,因此浮头式换热器不会产生较大的温差热应力,这样便避免了对换热器结构的损害。

此外,浮头式换热器还便于拆卸、易于清洗,适用于壳体和管束温差较大或壳程介质易结垢的场合。

因此在石油化工以及其他相关行业中得到了广泛的应用。

该设计主要进行了换热器结构的研究和各处强度的校核。

根据所提供的设计条件,以及GB150-2011《压力容器》、GB151-1999《管壳式换热器》、《固定式压力容器安全技术监察规程》等标准确定出换热器各个零部件(管箱、封头、法兰、开孔接管、折流板、钩圈等)的具体方案,包括各处材料的选择,各零部件的基本结构,壁厚计算及强度校核,开孔补强计算,管板、法兰以及浮头钩圈的强度计算等。

本设计历时3个月,共完成说明书一份,A1图纸5张,外文翻译一份。

Thermal Expantion 说明书TS server 特殊使用版---- daddy pitter johnbanq------------------------------------------------------------------------------- 基础合成:这个mod东西有点少,但是都挺实用的无论如何,先从基础开始!月牙扳手[好二,叫扳手不就行了么]这个东西可以通过右击改变TE[这个MOD]机器的方向这也可以拿来当BC扳手使也可以拿来右击原版物品,来使其旋转方向[活塞,弹射器什么的]机器部件:机器底盘气动伺服系统红石线圈新增额外配方:火药纸PS:矿渣在炉子里面烧会得到石棉合金:钢铁[PS:注意,那个是木炭]青铜黄铜黄铜到青铜PS:这些合金可以跟其他forge mod兼容-------------------------------------------------------------------------------------------------------------------------------------------------------------- 机器:哎哟卧槽!工业没了,没有炉子了!肿么办!!!!!别慌!动能炉来救场!GUI讲解:这里我拿动能炉子做1个示例,以后旁边的东西我就不讲了最左边的蓝色条子,是该物品存储BC动力的量右边的选项,第一条是能量,显示现在使用的MJ/最大MJ用量/储存了多少MJ[PS:MJ是MinecraftJoule,MC焦耳,是BC能源单位]然后下面是各种设置/信息,这里就不详细讲了参数:该炉子可以存储9600MJ(6个煤炭当量)存储的能源最高可以烧1组物品[烧1个物品需要3MJ]输入/输出面[后面会讲]:输入*1:蓝色面输出*1:橙色面[接下来,输入/输出面只说颜色]磨粉机:这个…..少年,说好了啊,这个可不是某工业的打粉机这个机器非常的神奇,可以把1个东西粉碎成另一个东西[这不废话呢么] 有时候还会产生1个副产品:此乃GUI是也!这个吗……..骨头6个骨粉甘蔗2个糖参数:机器使用能源:7MJ/tick机器储存能源上限:22400MJ(14煤炭当量)存储的能源最多可以粉碎一组物品输入/输出面:输入*1:蓝色输出*2:黄色[产品] 红色[副产品]PS:橙色是产品和副产品都输出锯木机:没有木头,或者手残和错东西了,怎么办????锯木机帮你取回木头!GUI:PS:处理原木的时候有多50%的木板可以锯的物品:100%出现的参数:机器运转需求:6MJ/tick 上限存储:19200MJ(12煤当量)存储的能量可以处理1组物品输入/输出面:输入*1:蓝色输出*2:黄色[产品] 红色[副产品]PS:橙色是产品/副产品2个都输出锯末的处理方法:此乃压缩锯末,在炉子里可以烧成木炭感应炉:没了工业,没了粉碎机,没了矿物翻倍啊……莫担心!此乃感应炉!这个炉子只能处理粉末状矿物/原矿状矿物当然,也支持铜/锡/银而且输出乘以2![记住了,这东西不能烧工业的粉!,所以是别做梦*4了!]烧东西需要注意的:记好了!这东西不是只用放矿就行的,需要1点助焊剂[沙子]每烧1个物品,就会需要1个沙子[自然,输出乘以2]没有沙子就罢工!!![对了,烧的时候会有副产品,炉渣]炉渣可以再烧一次得到石棉,长得跟羊毛一样,只不过不会被烧万能的GUI参数:工作时需要的能源:9MJ/tick可以存28800MJ(18个煤炭当量)可以烧一组物品输出/输入面:输入*1:蓝色输出*2:黄色[产品] 红色[副产品] 橙色[可选/成品+副产品]冰川除尘器[大误] 冷冻器:正如名字一样,是给冰川除尘……[除泥煤]是拿来冷冻水的把水冷冻成各种各样的……..GUI:输入/输出面:输入:随便,插水管就行[把水桶放进去,水会进去,但是不会弹出空桶] 输出*1:橙色以下是废话[作者说这个机器不需要BC能源的原因]:之所以不让这个机器需要BC能源,是因为将水变成冰需要的阶段改变能源…太低了,以至于可以忽略. 从IC2核电系统的数据,我们可以推导出:一桶水值250点冷却, 然而一块冰值300. 假设1热能单位= 1能源单位(基于铀的发电量和发热量),将水变成冰需要50EU或者20MJ的能量. 这点能量相当的渣渣, 就算需要能源,玩家用1个红石引擎就成了. 为了取得1个平衡点, 合成用的伺服部件用到了制造两个红石引擎中比较“难得“的材料(也就是玻璃和活塞), 这样子就平衡了,而且省空间多了..岩浆坩埚[我偏向叫做熔化炉]:这个东西很简单,就是用MJ把石材,石头,黑曜石,地狱岩融化成岩浆GUI:输入/输出面:输入*1:蓝色输出:任意一面,有管道就行[放桶进去,要是岩浆够多的话可以把岩浆装桶,但是不会自动弹出,要用木管道抽] [PS2:岩浆是自动出来的,不用抽]生产表:最大使用MJ量:40MJ/t融化石材/石头/黑曜石需要20000MJ 融化地狱岩需要4000MJ以下是废话[作者的设计原因]:对于石头们来说,天下没有免费的午餐–它们需要很多能源才能让岩浆在原版炉子里面烧所产生的能源等价. 之所以让地狱岩少用点能源,是有以下2个原因:1) 这很科学–用你的脚后跟想想,这可是地狱来的石头,别考虑那么多了,用就是2)可以减少服务器大姨妈/卡巴斯基的次数. 流动水自古对服务器不怎么好. 正如你所知道的,地狱里面岩浆是无穷无尽的,当有一个二逼青年意识到并且开始应用的时候. 自然,当他一边抽岩浆一边呵呵呵呵的时候, 就会产生大量的流动岩浆. 这个设备就是让地狱在不卡[不必吸岩浆的情况下]依旧可以是一个很好的岩浆源. 从游戏角度考虑, 也只不过有一丝不同–跑到地狱然后把地狱里面的东西洗劫一空. 而且,这也让地狱岩摆脱渣渣的位置了啊!冷却器/灭火器:这个东西说白了就是把岩浆和水降温,变成石头/石材/黑曜石输入/输出:输入:通水管和岩浆管道就没问题桶岩浆和一桶水,不然不会工作]以下是废话[作者设计的原因]:之所以制造石材不需要水或者岩浆,是因为刷石机已经在MC里面十分常见,而且成为了MC 的一大怪- 这个机器也应该遵循这个有点荒唐的原理. 石头需要岩浆,是因为为了抵消熔炉里面消耗的能量,或者一个有精准采集附魔的镐子. S不过,一桶岩浆可以生成500个石头,但是你要是在炉子里面烧一次的话,用量就是其4倍. 当然,这些生成都是玩家可以自己动手做到的,没必要用BC能源.蓄水器这个东西可以自动抽取旁边一格方块的水当然,你要是通上红石,就会从空气中吸水[速度爆慢]GUI这台机器可以被看成1个1个格子的箱子[好怪]可以用管道送物品进去,也可以抽出来[要是有足够水的话,放进桶就可以自动装桶]注意:要想搞无限水的话,这个方块旁边至少要有2个抽取水源的地方,不然会把造无限水的水源干掉输入/输出:输出:通管道就行,别废话了[PS:液体自动输出,不用抽]以下废话[作者设计的意图]:这个机器是因为2个目的而存在的: 防止服务器卡巴斯基,还有防止无限资源“用尽“. 这货不需要BC能源主要有2个原因:1)这货只能抽水.2) 你真的要无限水,一个红石引擎供能就够了–但是伺服器配件里面已经有需要合成红石引擎的大部分重要物品了. 这个系统的产水量相当于1个连着4个红石引擎的水泵,但是,嘿!这家伙只抽水!你供能有毛线必要啊基础教程:这里将会教授如何使用这个MOD里面的大部分现有机器,专为新人上路使用,若要寻找某个机器的用法,请见专门机器的说明页这个MOD的机器是可以转向的,正如你所知道的,也就代表可以让玩家更加省事地修建工厂:这里将会使用磨碎机作为例子.以下是粉碎机标准的设定:GUI看起来是这样的:在上面的图上我们可以看出,蓝色是输入,黄色和红色是输出. 黄色是主产品–产物会自动送到连接到黄色面的存储器[箱子etc]或者BC管道里. 红色是副产品-产物会自动送到连接到红色面的存储器[箱子etc]或者BC管道里注意:其他机器也可以作为存储器–理论上可以完全做一个不需要管道的生产线在机器放下后,机器就会有默认的配置方案. 在默认情况下,输入在左边, 输出在右边或者上面. 但是,这个设定可以更改.你可以用扳手(1),来改变机器的位置,下面是合成法::拿着右击机器会改变其方向.让我们右击打开机器,然后选择设定分栏:这个是磨碎机的默认设定,输入在左边和后面, 输出在右边和上面.点击某一面会改变那面的颜色. 来,让我们重新设定一下::按Esc关闭GUI之后,机器就是这样的了::so现在机器的输入面在右边和后面, 主产品输出在上面, 左边则是副产品输出. 是不是很酷? 接下来我们继续乱搞一通:默认情况下,机器只有1个输出,而且以橙色来标记输出面.有2个输出的机器则会用红色和黄色. 如果有2个输出的机器有橙色的话, 那么主产品和副产品都会走橙色,红色和黄色就会被忽略你会注意到2个输出槽都变成橙色的了,所以,现在东西都会从橙色区走.同时,输入面不是蓝色的了–因为现在的设计没有蓝色. 这也代表着你不能通过管道系统自动放东西进去了(2).然后这台机器就像没有输入一样了.在这个样本里, 这个机器有2个橙色面, 那么物品走哪个管道呢?这个首先取决于哪个连接了管道. 在这样情况下,如果都连接了,则输出不是随机的. 而是专门针对某1面输出. 要是有多个面得话,输出优先级分别为:下面, 上面,北向, 南向, 西向, 东向.这也就是说生产线只会和你设计的一样运转–检查输出是不会有得到–要是物品跑错了地方,那么你就有必要查查设定了.你也可以设定无色面,就可以应用普通管道系统了[用木头管道抽]你也可以使用红石控制机器,右击打开机器然后选择红石项你将会看见2个按钮:左边的是让机器遵循,还是忽略红石信号.如果你关掉,就会自动忽略红石,这个是默认打开的右边的那个是绝对机器是在什么样的红石信号下打开,开(High),还是关(Low).这个默认的设定是low.备注1) 月牙锤子的确不是一个存在的工具. 但是月牙扳手是1个真正的工具,.2) RedPower 管道会遵循输入/输出规则–管道将不会将物品送入输出端. 但是,机器会直接连接RP管道. 要使用某些中继才行.。
