进气口和排气口则用于控制气体的进出。
整个结构简单而紧凑,适用于各种工业场合。
接下来,让我们进入气动马达的工作原理部分。
当气体进入气缸时,气缸内的转子就会受到气体压力的作用而开始转动。
转子的转动会带动定子一起转动,从而产生动力输出。
这种工作原理与内燃机类似,都是通过燃烧或压缩气体来驱动机械运动。
通过动画演示,我们可以清晰地看到气动马达内部的工作过程。
当气体进入气缸时,转子开始转动,定子随之转动,从而驱动外部设备进行工作。
整个过程简单高效,能够满足各种工业生产的需求。
除了工作原理,气动马达的优点也是我们需要了解的重点之一。
首先,气动马达不会因为过载而烧坏,因为气体的压力是可控的,这在某些需要长时间连续工作的场合非常重要。
其次,气动马达的维护成本低,因为它的结构简单,零部件少,不易出现故障。
最后,气动马达的使用寿命长,能够适应各种恶劣的工作环境,稳定可靠。
通过动画演示,我们可以更生动地了解气动马达的工作原理和结构特点,这有助于我们在实际工作中更好地应用气动马达,提高生产效率,降低成本。
总的来说,气动马达原理的动画演示为我们提供了一个直观、清晰的学习工具,让我们更好地了解气动马达的工作原理和结构特点。
通过深入学习和实践,我们可以更好地应用气动马达,为工业生产提供更加稳定可靠的动力支持。

气动元件使用说明1气动元件使用说明气压传动系统中,气源处理件是指空气过滤器、减压阀和油雾器,有些品牌的电磁阀和气缸能够实现无油润滑(靠润滑脂实现润滑功能),便不需要使用油雾器!过滤度一般为50-75μm,调压范围为0.5-10mpa,如需过滤精度为5-10μm,10-20μm,25-40μm,及调压为0.05-0.3mpa,0.05-1mpa三大件无管连接而成的组件称为三联件。
三大件是多数气动系统中不可缺少的气源装置,安装在用气设备近处,是压缩空气质量的最后保证。
三大件的安装顺序依进气方向分别为空气过滤器、减压阀和油雾器。
空气过滤器和减压阀组合在一起可以称为气动二联件。
还可以将空气过滤器和减压阀集装在一起,便成为过滤减压阀(功能与空气过滤器和减压阀结合起来使用一样)。
有些场合不能允许压缩空气中存在油雾,则需要使用油雾分离器将压缩空气中的油雾过滤掉。
总之,这几个元件可以根据需要进行选择,并可以将他们组合起来使用。
空气过滤器用作对气源的洁净,可以过滤器压缩空气中的水分,防止水分随其气体步入装置。
减压阀可以对气源展开稳压,并使气源处在恒定状态,可以增大因气源气压变异时对阀门或执行器等硬件的受损。
过滤器用作对气源的洁净,可以过滤器压缩空气中的水份,防止水份随其气体步入装置。
油雾器可对机体运动部件进行润滑,可以对不方便加润滑油的部件进行润滑,大大延长机体的使用寿命。
气源处置件采用表明:1、过滤器排水有压差排水与手动排水二种方式。
手动排水时当水位达到滤芯下方水平之前必须排出。
2、压力调节时,在旋转旋钮前恳请先挤到再转动,甩下转动钮为定位。
转动钮向右为调低出口压力,向左转动为调高出口压力。
调节压力时应逐步光滑地调至所须要压力值,不应当一步调节妥当。
3、给油器的使用方法:给油器使用jisk2213输机油(isovg32或同级用油)。
加油量请不要超过杯子八分满。
数字0为油量最小,9为油量最大。
自9-0位置不能旋转,须顺时针旋气源处置件包含过滤器、减压阀、过滤器减压阀、油雾器以及它们共同组成的二联件、三联件。

空气预热器技术说明2007-9-19空气换热器1、前言冶金行业是国家能源消耗大户,同时也是环境污染的主要制造者之一。
国家制订的可持续发展的长期目标,其重要保证条件就是降低冶金行业能耗,提高能源利用率,减少污染排放,实现和谐发展。
冶金行业要降低能耗,除了改善生产工艺和条件,另外的一个重要途径就是充分利用排放掉的能源,从而提高能源利用效率。
利用排放掉能源的主要设备就是换热器。
管壳式换热器是一种常见的换热设备,已经有近百年的历史。
目前已经已经有非常多的种类,广泛应用于各种行业。
管壳式换热器的特点是:换热空间是管束以及管束外面的壳体与管束形成的空间。
一种流体走管内,另外的流体走管与壳之间。
两种流体通过管壁进行换热。
管壳换热器的优点是应用广泛,可以耐高温高压,可以大型化,它的缺点是传热系数比较低,单位换热面积消耗的金属材料比较多。
为了解决这个问题,人们采取了很多方法来改善管壳换热器的传热条件。
2、螺纹管螺纹管是上世纪末出现的一种异形传热管,它通过对光滑钢管进行压力加工,使其发生螺纹状形变,表面形成螺纹凹槽而成。
螺纹管同光滑管比有非常明显的性能增强:①由于螺纹凹槽的形成,可以使管内气流形成旋流,增强了紊流状态下的对流传热能力;②螺纹凹槽使得管子表面变得粗糙,破坏了气流边界层,使得在层流状态下气体对流传热有明显提高;③螺纹凹槽可使管子传热表面积有所增加;④螺纹管比光滑管的固有频率提高,降低了换热器的振动。
但是螺纹管的阻力比光滑管大,管子刚度也比光滑管小,这是螺纹管存在的缺点。
AA2 机组空气预热器的换热元件就采用单程轧槽螺纹管。
3、换热器结构换热器采用高温列管式,风箱为方形,烟气走管外行程,空气走管内行程。
整个换热器嵌入烟气通道内,没有外壳。
烟气经过换热管外换热后直接排放掉,为一个行程。
空气经过四个管行程被烟气加热,管束用风箱和连接管连接,连接管高温端有膨胀节。
空气流与烟气流呈逆差流的流动分布。
4、换热器参数4.1 烟气参数:入口温度:850C 出口温度:393C烟气量:9636m3/h・C 阻力损失:62Pa烟气放出热量:1.405 x 106kcal/h4.2空气参数:入口温度:20C 出口温度:550 C空气量:7524m3/h・C 阻力损失:770Pa空气吸收热量:1.286X 106kcal/h4.3换热管参数:管子类型:单程轧槽螺纹管光管规格:© 45X 2.5X 1900,中间有折弯管子数量:276 X 4=1104根4.4管子排布:迎风面截距110mm,气流方向截距67mm,三角形错排4.5传热参数:管外传热系数:28.8kcal/m2- h -C管内传热系数:84.1 kcal/m2- h -C综合传热系数:20.8 kcal/m2- h -C传热面积:215m24.6材质:由于换热器管壁温度有超过500C的部分,所以前两行程的管材为1Cr18Ni9Ti ,并且热浸镀渗铝,后两行程的管材为20g, 符合GB3087-99 标准, 样也热浸镀渗铝。

电动机安装在下梁的下部,通过与转子接长轴连接,带动转子旋转。
为防止空气向烟气侧泄漏,在转子上、下端半径方向,外侧轴线方向,以及圆周方向分别设有径向、轴向及旁路密封装置,采用双密封结构以降低漏风率。
此外,预热器上还配有火灾检测消防和清洗系统,吹灰装置、润滑及控制等设备(见图1及图2)。
二主要部件1.转子本空气预热器转子采用模数仓格结构,每个仓格为15度,为布置双密封结构,每个仓格又分隔为两(见图4),全部蓄热元件分装在24个模数仓格内,每个模数仓格利用一个定位销和一个固定销与中心筒相连接。
由于采用这种结构,大大减少了工地的安装工作量,并减少转子内焊接应力和热应力。
中心筒上、下两端分别用M12和M42和金螺栓连接上轴和下轴,接长轴通过M42合金螺栓与下轴相连,整体形成预热器的旋转主轴。

Your reading and understanding of these safety symbols are very important-Danger is used only when your action or lack of action will cause serious human injury or death.- Warning is used to describe any action or lack of action where a serious injury can occur. IMPORTANT – Important is used when action or lack of action can cause equipment failure, either immediate or over a long period of time.: It is the operator’s responsibility to read and understand the following safety statements, •Only qualified operators should install, operate, adjust, maintain, clean, repair, or transport this machinery•These components are designed for general use in normal environments. These components are not specifically designed for lifting and moving people, agri-food machinery, and certain types of mobile machinery or special work environments such as: explosive, flammable or corrosive. Only the user can decide the suitability or this machinery in these conditions or extreme environments. AME will supply information necessary to help make these decisions.These instructions are intended for end-user application needs. Most problems with new equipment are caused by improper operation or installation. Detailed service repair instructions or parts list can be obtained from AME.Operating InstructionsSAFETY PRECAUTIONSGeneral Operation•All WARNING statements must be carefully observed to help prevent personal injury.•Before operating the pump, all hose connections must be tightened with the proper tools. Do not over tighten.Connections should be only be tightened securely and leak-free. Over tightening can cause premature thread failure or high pressure fittings to split at pressures lower than their rated capacities.•Should a hydraulic hose ever rupture, burst, or need to be disconnected, immediately shut off the pump and release all pressure. Never attempt to grasp a leaking pressurized hose with your hands. The force of escaping hydraulic fluid could cause serious injury.•Do not subject the hose to potential hazard such as fire, sharp surfaces, extreme heat or cold, or heavy impact.Do not allow the hose to be altered or kink, twist, curl, crush, cut, or bend so tightly that the fluid flow within the hose is blocked or reduced. Periodically inspect the hose for wear, because any of these conditions can damage the hose and possibly result in personal injury.•Do not use the hose to move attached equipment. Stress can damage hose and possibly cause personal injury.•Hose material and coupler seals must be compatible with the hydraulic fluid used. Hoses also must not come in contact with corrosive materials such as creosote-impregnated objects and some paints. Consult the manufacturer before paining a hose. Hose deterioration due to corrosive materials can result in personal injury.Never pain the couplers.•Inspect machine for wear, damage and correct function before each use. Do not use machinery that is not in proper working order, but repair or replace it as necessary.•Replace worn or damaged safety decals.•Modification of a product requires written AME authorization.•Use only components with the same pressure rating when assembling a system or machine.Pump•Do not exceed the hydraulic pressure rating noted on the pump data plate or tamper with the internal high pressure relief valve. Creating pressure beyond the rated pressure can result in personal injury.•Before replenishing the fluid level, retract the system to prevent overfilling the pump reservoir. An overfill can cause personal injury due to excess reservoir pressures created when cylinders are retracted.Air Supply•Shut off and disconnect the air supply when the pump is not in use or before breaking any connections in the system.PREPARATION & SET-UPAir Supply Hook-UpRemove the thread protector from the air inlet of the pump. Select and install the threaded fittings which are compatible with your air supply fittings. The air supply should be 20 CFM (.57 M3/min.) and 100 PSI (7 BAR) at the pump to obtain the rated hydraulic pressure. Air pressure should be regulated to a maximum of 140 PSI (9 BAR). Secure your pump fitting to the air supply. See illustrations on following pages.: If improperly used, pressurized equipment can be potentially hazardous. Therefore: •Hydraulic connections must be securely fastened before building pressure in the system.•Release all system pressure before loosening any hydraulic connection in the systemVenting the ReservoirTo improve hydraulic fluid delivery and increase useable hydraulic fluid capacity,Remove shipping plug and install filler/vent cap before using the pump.InstructionsOperatingHydraulic ConnectionsClean all the areas around the fluid ports of the pump and cylinder. Inspect all the threads and fittings for signs of wear or damage and replace as needed. Clean all hose ends, couplers and union ends. Remove the thread protectors from the hydraulic fluid outlets. Connect the hose assembly to the hydraulic fluid outlet and couple the hose to the cylinder. See illustrations below.IMPORTANT: Seal all external pipe connections with a high-grade, non-hardening thread sealant. Teflon tape may also be used to seal hydraulic connections, provided only one layer of tape is used. Apply the tape carefully, two threads back, to prevent it from being pinched by the coupler and broken off inside the system. Any loose pieces of tape could travel through the system and obstruct the flow of fluid or cause jamming of precision-fit parts.This pump is equipped with a two position, 3-way / 4-way control valve for operating single- or double acting hydraulic cylinders and requires attaching the hoses in the following manner:When using a single-acting cylinder, attach one end of a hose to port ‘’A’’ of valve and the end of the hose to the advance port ‘’C’’ of the cylinder. Then Install a pipe plug in valve port ‘’B’’. If the hoses are frequently connected and disconnected, quick couplers should be used to prevent wear and tear on the fittings.When using a double-acting cylinder, attach one hose to port ‘’A’’ of valve and the other end of the hose to the advance port ‘’C’’ of cylinder. Attach the second hose to valve port ‘’B’’ and the other end of the hose to cylinder.ofportreturn‘’D’’Operating InstructionsFor Remote Controlled Pumps:1.Connect the pump to a remote 3-way/4-way valve2.Connect the fluid line from the pressureport on the manifold to the pump pressureport on the valve.3.Connect the fluid line from the fluidreturn port on the manifold to the pumpreturn port on the valve.4.Connect the cylinder(s) to the valve.IMPORTANT: On all single pressure lineapplications, plug one port on the valve.1.Connect the ports of the pump valve toCylinder(s).

To accomplish this, perform the following procedure:For Hand/Foot Operated Pumps:1.Press the release end of the pedal while holding down the air intakeValve with a flathead screwdriver. The air intake valve is locateddirectly under the pedal in the area marked . The Valve isdepressed simultaneously with the area of the pedal duingprinting.2.Allow the pump to cycle approximately 15 seconds.3.Remove the screwdriver, and press end of the pedal oncemore.4.If the cylinder extends or pressure builds, the pump has beensuccessfully primed. If the pump does not respond, repeat theprocedure, jogging the air intake valve while holding the pedal inthe position.For Manual Valve Operated Pumps:Disconnect the hose end at the advance port of the cylinder. Direct the hose end into a suitable container or back into the pump reservoir. Shift the valve to the ADVANCE position and depress the end of the foot pedal inscribed with. Allow the pump to cycle until the fluid begins to flow freely into the container or reservoir. Reconnect the hose end to the cylinder advance port. Shift the valve to the Advance position and reactivate the pump. If the cylinder extends or builds pressure, the pump has been successfully primed. If not refer to the Trouble - Shooting Guide of these instructions.For Remote Controlled Pumps:Depress the AND buttons on the remote hand control simultaneously and allow the pump to cycle for approximately fifteen seconds. Release both buttons and then depress the button once more. If the cylinder extends or pressure builds, the pump has been successfully primed. If the pump does not respond repeat the procedure. If the pump still does not respond, tip pump upside down and repeat procedure.For Tandem Pumps:1.Connect the fluid line to the pressure port and keep the return port plugged. Place the other end of the fluid linein the pump filler hold.NOTE: If the fluid lines are connected to a remote valve, shift the valve into the center position and plug both cylinder ports on the valve. This lets fluid circulate through the valve and back to the pumpreservoir; thereby allowing the pump to prime.2.Attach air line with shut-off valve to the pump.3.Open the air valve, Pump will begin to reciprocate, and fluid will advance through the hose or fluid line andreturn to the pump reservoir. Allow the pump to cycle approximately 15 seconds.4.Plug the manifold pressure port, or shift the valve to pressurize the circuit.if the pump builds pressure, it has been successfully primed.Operating InstructionsPump OperationFor Hand/Foot Operated Pumps:1.To extend the cylinder, depress the pedal on the end marked2.To hold the cylinder in position, release the end of foot pedal marked with to deactivate the pump.3.To retract the cylinder, depress the pedal on the end marked .For Remote Controlled Pumps:1.To extend the cylinder, depress the button on the remote hand control marked2.To hold the cylinder in position, release the button.3.To retract the cylinder, depress the button on the remote hand control markedFor Manual Valve Operated Pumps:1.To extend the cylinder, shift the valve handle to the advance position and depress the end of the foot pedalinscribed with to activate the pump.2.To hold the cylinder in position, release the end of foot pedal inscribed with to deactivate the pump.3.To retract the cylinder, shift the valve handle to the retract position and depress the end of the foot pedalinscribed with to activate the pump.For Pumps with Air Regulators:1.Open the air shut-off valve (if so equipped) or connect the air quick coupler (if so equipped).NOTE: under certain circumstances the pump may need to be primed before operation. Refer to the method described in the section entitled ‘’Priming the Pump Unit.’’2.Slowly turn the air regulator control on unit clockwise to increase pressure, counterclockwise to decreasepressure. As air is admitted to the pump unit, It will begin to deliver fluid to the system. Continue to slowly turn the air regulator control clockwise until the gauge reads the maximum hydraulic pressure rating as stated on the pumps data plate. A maximum hydraulic pressure reading should be obtained if air pressure is approximately 100 PSI (7 BAR).3.Cycle the system several times by manually shifting the 3-way/4-way valve (if so equipped) or the remote valve(if so equipped). Set the air regulator to obtain the desired hydraulic pressure. When decreasing pressure, shift the valve after each adjustment before measuring actual hydraulic pressure.4.Shut off and disconnect air supply to the pump and shift pump valve (if so equipped) or remote valve (if soequipped) two times to release all system pressure. Check fluid level with hydraulic system retracted. The pump is now ready for operation.NOTE: • The Hydraulic pressure is increased or decreased by adjusting the air inlet pressure at the regulator.•On two stage pumps, the air pressure regulator that is mounted on the pump controls only the output from the high pressure stage. The output of the low pressure stage of the pump is determined by the air line pressure coming from the remote regulator. A remote regulator is required to control the air pressure from the air line. The independent functioning of the low and high pressure stages of this pump can best be described as follows. At the minimum air line pressure of 40 PSI (3 BAR), the low pressure stage of the pump will deliver 480 PSI (33 BAR) hydraulic pressure (with the pump regulator turned counterclockwise to prevent air pressure from activating the high pressure stage of the pump.) At the minimum air line pressure (with the pump regulator turned clockwise to allow air pressure to reach the high pressure stage.) Always remember that the pump regulator must be turned fully counterclockwise when the pump is used to produce 1,200 PSI (83 BAR) or less.Operating InstructionsRefilling the ReservoirIf the additional fluid must be adder to the reservoir, use only approved hydraulic fluid (215 SSU @ 1000 F [380 C]). Clean the entire area around the filler plug before adding fluid to the reservoir. Remove the filler plug, and insert a clean funnel with filter. The cylinder must be fully retracted and the air supply disconnected when adding the fluid to the reservoir.Periodic CleaningIMPORTANT: The greatest single cause of failure in hydraulic pumps is dirt. Keep the pump and attached equipment clean to prevent foreign matter from entering the system.A routine should be established to keep the pump as free from dirt as possible. All unused couplers must be sealed with thread protectors. All hose connections must be free of grit and grime. Any equipment hooked up to the pump should also be kept clean. Use only approved hydraulic fluid in this unit and change as recommended (every 300 hours).ACCESSORIESGauges and accessories may not be included with the pump. However, a hydraulic gauge is strongly recommended whenever the pump is used.•The Gauge must be of the proper rating for pressure used!• Use only approved accessories, hydraulic fluid, and repair parts!Installing an In-line Air Pressure Gauge1.Remove the male fitting from the air filter and install a tee adapter, with gauge, between the hose and air filter.2.Install male fitting into the tee adapter and securely clamp the hose to the male fitting.Installing an In-line Hydraulic Pressure Gauge1.Remove the thread protector from the hydraulic outlet port and inspect the threads and fittings for signs of wear.2.Install a tee adapter, with gauge, between the hose coupling and the pump hydraulic outlet port.3.Tighten all connections securely! DO NOT OVERTIGHTEN HOSE CONNECTIONS.Fire-Resistant Hydraulic FluidFlame Out 200TM fire-resistant hydraulic fluid is compatible with all AME hydraulic equipment. The use of this fluid does not require the changing of seals in any AME pump or cylinder and is available through your local Hydraulic Fluid Distributor.Operating InstructionsPREVENTIVE MAINTENANCEIMPORTANT: • Any repair or servicing that requires dismantling the pump must be performed on a dirt-free environment by qualified technician.• Dispose of machine and fluids properly.LubricationFor Hand/Foot, Manual Valve, and Remote Control Operated Pumps:If the pump is operated on a continuous duty cycle for extended periods, the manufacturer recommends installing an automatic air line oiler in the air inlet line as close to the pumping unit as possible. Set the unit to feed approximately one drop of oil per minute into the system. Use SAE grade oil, 5W to 30W.For Tandem Pumps:These models have an integral air pressure regulator, air filter and lubricator. Set the lubricator to feed one drop of oil per minute to the system. Use SAE grade oil, 5W to 30W. For serving the air regulator, lubricator and filter system see the operating and service instructions provided.Bleeding Air from the SystemDuring the first moments of operation or after prolonged use, a significant amount of air may accumulate within the hydraulic system. This entrapped air may cause the cylinder to respond slowly or behave in an unstable manner. To remove the air, run the system through several cycles (extending and retracting the cylinder) free of any load. The cylinder must be at lower level then the pump to allow air to be released through the pump reservoir.Inspecting the Hydraulic Fluid LevelCheck the fluid level in the reservoir after every 10 hrs of use. Drain and replenish the reservoir with Approved hydraulic fluid after every 300 hours of use approximately.For Pumps with 105 cubic Inch (1.7 l) reservoir capacity:The fluid level should be inch (12.7 mm) from the filler/vent cap with all cylinders retractedFor pumps with a 2 gallon (7.6 l) reservoir capacity:The fluid level should 1-3/4 inch (44.5 mm) from the filler/vent cap with all cylinders retracted.Draining and Flushing the ReservoirIMPORTANT: Wipe the pump exterior completely clean before attempting this procedure!1.Remove the screws that fasten the pump assembly to the reservoir. Remove the pump assembly fromthe reservoir. Do not damage the gasket, filler or safety valve.2.Drain the reservoir of all fluid and refill half full with clean hydraulic fluid. Rinse the filter clean.3.Place the pump assembly back onto the reservoir, and secure with two of the machine screwsassembled in opposite corners of the housing.4.Run the unit for several minutes. Use the same method described in the section titled ‘’Priming thePump Unit.’’5.Drain and clean the reservoir once more.6.Refill the reservoir with Approved hydraulic fluid and replace the pump assembly (with gasket) on thereservoir pounds (2.8 to 3.4 N•m); for 2 gallon (7.6 l) reservoirs, torque to 35 to 45 inch pounds (4.0 to 5.0 N•m)IMPORTANT: Drain and clean the other hydraulic system components (hoses, cylinders, etc.) before reconnecting them to the pump. This will prevent contaminated fluid from entering the pump again.Operating InstructionsOPERATOR TROUBLESHOOTING GUIDEIf this guide does not resolve your pump problem,Contact an authorized hydraulic service center or a company headquarters listed on back sheet 5 of 5.PROBLEMS CAUSE SOLUTIONPump reciprocates but no fluid 1.
