The value thus obtained is then compared with the figures in the minimum air pressure column in the torque table. Having found the same or nearest value (in excess), the suitable model can be read off the column to the left.The spring return actuator, on the other hand, has four torques: springbreak , pneumatic break (usually the same) pneumatic end and spring end (usually the same). Choice of actuator here depends on various factors (valve type, normally open or closed) and the method is usually the same as that of double acting models, except that the value must be compared with the lower of spring and pneumatic end . The value of the springs can in any case be modified to adapt the actuator’s torque to the value required by the valve.DOUBLE ACTING%2040608010045°AIRSPRING RETURN%2040608010045°Torque %AIRSPRINGSTorque Outputs (Nm) - Spring Return Actuator (SN250 - SN300)Parts & Materials Lists S050 - S20019820109138112242322326754a42712* Parts Included in Repair KitParts & Materials List SN250 - SN300* Parts Included in Repair KitDimensions S050 - S200Dimensions SN250 - SN300NOTE: For optional G½ Inlet Block, order separately using code 428132Automax Actuator Coding Operating ConditionsMedia Air or non-corrosive fluid.The media should have a dew point at least10°C below the ambient operating temperature.Temperature Range Standard -20°C to +80°CLow temperature variant -50°C to +80°CHigh temperature variant -20°C to +150°CRotation Pinion rotates anti-clockwise when the centre(viewed from top)chamber supply port (RHS) is pressurised.Reverse acting options available.Travel Average 100° total travel to provide nominal(all sizes)5° over travel clockwise and anti clockwise.SN250/SN300 models - travel stops in outwarddirection only.Extended Travel180°, 140°, 120°.

Robots机器人 中英文翻译

RobotsA robot is an automatically controlled, reprogrammable, multipurpose, mani pulating machine with several reprogrammable axes, which may be either fixed in place or mobile for use in industrial automation applications.The key words are reprogrammable and multipurpose because most single-purpose machines do not meet these two requirements.The term”reprogrammabl e” implies two things:The robot operates according to a written program can b e rewritten to accomdate a variety of manufacturing tasks. The term “multipurp ose” means that the robot can perform many different functions, depending on the program and tooling currently in use.Over the past two decades,the robot has been introduced into industry to perform many monotonous and often unsafe operations. Because robots can per form certain basic tasks more quickly and accurately than humans, they are bei ng increasingly used in various manufacturing industries.Structures of RobotsThe typical structure of industrial robots consists of 4 major components: the manipulator, the end effector, the power supply and control syterm.The manipulator is a mechanical unite that provides motions similar to those of a human arm. It often has a shoulder joint,an elbow and a wrist. It can rotate or slide, strech out and withdraw in every possible direction with certain flexibility.The basic mechanical configurations of the robot manipulator are categorized as Cartesian, cylindrical, spherical and articulated.A robot with a Cartesian geometry can move its gripper to any position within the cube or rectangle defined as its working volum.Cylindrical coordinate robots can move the gripper within a volum that is described by a cylinder. The cylindrical coordinate robot is positioned in the work area by two linear movements in the X and Y directions and one angular rotation about the Z axis.Spherical arm geometry robots have an irregular work envelop. This type of robot has two main variants,vertically articulated and horizontally articulated.The end effector attaches itself to the end of the robot wrist, also called end-of-arm tooling.It is the device intended for performing the designed operations as a human hand can.End effectors are generally custom-made to meet special handling requirements. Mechanical grippers are the most commonly used and are equipped with two or more fingers.The selection of an appropriate end effector for a special application depends on such factors as the payload, enviyonment,reliability,and cost.The power supply is the actuator for moving the robot arm, controlling the joints and operating the end effector. The basic type of power sources include electrical,pneumatic, and hydraulic. Each source of energy and each type of motor has its own characteristics, advantages and limitations. An ac-powered motor or dc-powered motor may be used depending on the system design and applications. These motors convert electrical energy into mechanical energy to power the robot.Most new robots use electrical power supply. Pneumatic actuators have been used for high speed. Nonservo robots and are often used for powering tooling such as grippers. Hydraulic actuators have been used for heavier lift systems, typically where accuracy was not also requied.The contro system is the communications and information-processing system that gives commands for the movements of the robot. It is the brain of the robot; it sends signals to the power source to move the robot arm to a specific position and to the end effector.It is also the nerves of the robot; it is reprogrammable to send out sequences of instructions for all movements and actions to be taken by the robot.A open-loop controller is the simplest for of the control system, which controls the robot only by foolowing the predetermined step-by-step instructions.This system dose not have a self-correcting capability.A close-loop control system use feedback sensors to produce signals that reflct the current states of the controed objects. By comparing those feedback signals with the values set by the programmer, the close-loop controller can conduct the robot to move to the precise position and assume the desired attitude, and the end effector can perform with very high accuracy as the close-loop control system can minimize the discrepancy between the controlled object and the predetermined references.Classification of RobotIndustrial robots vary widely in size,shape, number of axes,degrees of freedom, and design configuration. Each factor influence the dimensions of the robot’s working envelop or the volume of space within which it can move and perform its designated task. A broader classification of robots can been described as below.Fixed-and Variable-Sequence Robots. The fixed-sequence robot (also called a pick-and place robot) is programmed for a specific sequence of operations. Its movements are form point to point, and the cycle is repeated continuously.The variable-sequence robot can be programmed for a specific sequence of operations but can be programmed to perform another sequence of operation.Playback Robot. An operator leads or walks the playback robot and its end effector through the desired path. The robot memorizes and records the path and sequence of motions and can repeat them continually without any further action or guidance by the operator.Numerically Controlled Robot. The numerically controlled robot is programmed and operated much like a numerically controlled machine. The robot is servocontrolled by digital data, and its sequence of movements can be changed with relative ease.Intelligent Robot. The intelligent robot is capable of performing some of the functions and tasks carried out by huanbeings.It is equipped with a variety of sensors with visual and tactile capabilities.Robot ApplicationsThe robot is a very special type of productin tool; as a result, the applications in which robots are used are quite broad. These applications can be grouped into three categories: material processing, material handling and assembly.In material processing, robots use tools to process the raw material. For example, the robot tools could include a drill and the robot would be able to perfor drilling operaytions on raw material.Material handling consists of the loading, unloading, and transferring of workpieces in manufacturing facilities. These operations can be performed relatively and repeatedly with robots, thereby improving quality and scrap losses.Assembly is another large application area for using robotics. An automatic assembly system can incorporate automatic testing, robot automation and mechanical handling for reducing labor costs, increasing output and eliminating manual handling concers.机器人机器人是一种自动控制的、可重复编程的、多功能的、由几个可重复编程的坐标系来操纵机器的装置,它可以被固定在某地,还可以是移动的以在工业自动化工厂中使用。

Valtek Spring CylinderLinear ActuatorsExperience In Motion2Adjusting ScrewAdjusting ScrewGasketCylinderPiston Stem O-ringPistonPiston O-ringYoke O-ringStem BellowsActuator StemStem ClampStem Clamp BoltingFlowserve spring cylinder linear actuators are powerful,compact, high-performance pneumatic actuators thatprovide solid throttling or on-off operation for automaticcontrol valves. The positioner supplies air to both sides ofthe piston, providing stiff, precise movement and high-fre-quency response and quick stroke speeds. The robust,flexible design allows a wide range of accessories, quickmaintenance in a small lightweight package. A selection ofhigh thrust springs provide reliable fail-safe operation. TheVL-UHC actuator is particularly well suited for applicationswhere high numbers of full stroke cycles are required Valtek Spring Cylinder Linear ActuatorFeatures and BenefitsImportant features and advantages of the Flowserve Valtek spring cylinder linear actuator include:3The VL series is the standard set of actuators for Valtek control valves, providing precise control and reliable perfor-mance. With decades of experience and reliability, VL actua-tors have been known to be in service for over 30 years. Providing maximum thrust from a compact lightweight package, the VL cylinder has set the industry standard for two generations.VL SeriesFeatures and BenefitsMaterials of Construction45For applications where aluminum materials are notacceptable, Flowserve offers the compact, lightweight and high thrust of the VL-C carbon steel spring cylinder linear actuator. Offering identical springs and all the advantages of VL actuators, the VL-C actuator replaces all aluminum parts with carbon steel.Offered in two styles, the size 25 and 50 square inch actua-tors use deep drawn cylinders while the size 100, 150, 200, 300 and 400 offers tie rod construction.VL-C SeriesFeatures and BenefitsMaterials of Construction*Stainless steel material on 25 and 50 square inch.6For applications where ultra high cycle (UHC) life is needed, Flowserve offers the exceptionally long cycle life of the VL-UHC series actuators. By adding and modifying several parts used in the standard VL series actuator, the VL-UHC gains a cycle life previously thought unattainable. The VL-UHC actuator is particularly well suited for applications where high numbers of full stroke cycles are required.VL-UHC SeriesFeatures and BenefitsMaterials of ConstructionAdjusting Screw Seal Thrust WasherJam Nut High Cycle Spring Quad Seal7Materials of ConstructionFeatures and BenefitsFor applications where longer strokes or unusually high spring thrusts are required, Flowserve offers the VL-ES series actuators. Using many of the same design concepts as the VL-C, the VL-ES offers external spring cans. This allows for extra long springs which provide longer stroke lengths and higher forces.VL-ES Series8Logix 3000 Series Digital PositionersLogix 500 Series Digital Positioners Common Positioners and Control SoftwareXL and Beta Series Analog Positioners ValveSight Diagnostic and PreventativeMaintenance Software9Auxiliary EquipmentPositioners• XL pneumatic or electro-pneumatic positioner • Beta pneumatic or electro-pneumatic positioner • Logix 500 digital positioner series• H ART• Logix 3000 digital positioner series• H ART• F oundation Fieldbus• StarPac digital flow measurement and control series Air Filters A variety of air filters are available.PosPac Position transmitter feeds back a 4-20 mA signal on position.Flow Booster For faster stroke times.Limit Switches SolenoidsOptional ConfigurationsMany optional configurations are available.

Limit Stop
The pinion and stop rotation can be adjusted by four large diameter adjustable set screws diametrically opposed and threaded into the actuator body. Each opposing pair of screws exerts simultaneous and equal forces on opposite sides of the stop when the rotation limit is reached, thus, no off-center forces are generated. The stop The stop allows for +/-5° of rotational adjustment in both directions of travel. Any intermediate position can be achieved with a longer set of stop screws. This feature is built into the actuator stop mechanism and eliminates the need for additional plates and screws. The stop material is St.St. for better wear and corrosion

COMPACT II 4 PISTON PNEUMATIC ACTUATOR
Less Wear
With its unique 4-piston design, the Compact II achieves a more uniform load distribution than do single and double piston actuators, therefore greatly reducing gear wear at the points of contact between rack and pinion. The force-balanced piston with its shorter stroke prevents uneven wear of O-rings, gear and pistons. This eliminates the need for bearings and reduces the number of soft parts, thereby resulting in longer maintenance schedules and low cost of repair kits. The high surface finish of the four cylinder is protected from wear due to the hardened surface created by the anodizing treatment.

Pneumatic ActuatorType 3277Fig.1· Type 3277 Pneumatic Actuator2· Type 3277-5 Pneumatic ActuatorMounting andOperating InstructionsEB8311 ENJuly 20061Design and principle ofoperationThe Type 3277Pneumatic Actuators with an effective diaphragm area of 240, 350 or 700 cm² are primarily mounted to control valves from the Series 240, 250 and 280.Type 3277-5 with a die-cast aluminum case and an effective diaphragm area of120 cm², is mounted to Type 3510 and Se-ries 240 Valves.The actuator is made up of two diaphragm cases, a rolling diaphragm and springs. The lower diaphragm case is permanently fixed to the yoke which allows the direct attach-ment of either a pneumatic or electropneu-matic positioner or a limit switch.Actuators with manual override (Fig. 5) ad-ditionally have a handwheel mounted on the diaphragm case. The handwheel moves theactuator stem over a spindle after the lock-ing mechanism (lock nut) has been disen-gaged. In addition, the actuator can be equipped in a special version with a me-chanically adjustable travel stop.The signal pressure creates a force at the di-aphragm surface which is balanced by the springs (6) arranged in the actuator. The number of springs and their compression determine the bench range (signal pressure range) while taking the rated travel into ac-count which is directly proportional to the signal pressure. A maximum of 30 springs can be installed, partly fitted inside one an-other.The stem connector (16) connects the actua-tor stem (2) with the plug stem of the control valve.2EB 8311ENDesign and principle of operationFail-safe actionWhen the signal pressure fails, the fail-safe action of the actuator depends on whether the springs are installed in the top or bottom diaphragm chamber.Actuator stem extendsWhen the signal pressure is reduced or the air supply fails, the springs move the actua-tor stem downwards and close the valve. The valve opens when the signal pressure is increased enough to overcome the force ex-erted by the springs.Actuator stem retractsWhen the signal pressure is reduced or the air supply fails, the springs move the actua-tor stem upwards and open the valve. The valve closes when the signal pressure is in-creased enough to overcome the force ex-erted by the springs.EB8311EN3Design and principle of operationLoading pressure connectionType 3277 Actuator(Fig. 3)In the Type 3277 Actuator with fail-safe ac-tion "Actuator stem extends", the loading pressure is connected to the loading pres-sure connection (11) at the side of the yoke to fill the bottom diaphragm chamber which causes the actuator stem (2) to move up-wards. In an actuator with the fail-safe ac-tion "Actuator stem retracts", the loading pressure is connected the loading pressure connection (4) to fill the top diaphragm chamber which causes the actuator stem to move downwards.Type 3277-5 Actuator(Fig. 4)In the Type 3277-5 Actuator, the loading pressure is connected to a borehole either at the left or right of the yoke. A switchover plate(14, accessories) directs the air to one of the diaphragm chambers, depending on the fail-safe action of the actuator ("Actuator stem extends" or "Actuator stem retracts"), which is determined by how the plate is aligned with the mark (14.4).4Turn the switchover plate to align the symbol (14.3) for the appropriatefail-safe action with the mark (14.4). SeeFig. 4, bottom left. The operating direc-tion (>>) or (<>) of the positioner deter-mines whether the left or right attach-ment is to be used.A connecting plate(accessories) is required instead of the switchover plate if the actua-tor is operated without a positioner. The loading pressure is directly connected to the loading pressure connection (14.8) of the connecting plate to fill the diaphragm cham-ber.4Turn the connecting plate to align the symbol (14.3) for the appropriatefail-safe action "Actuator stem extends"or "Actuator stem retracts" with the mark(14.4). See Fig. 4, bottom right.4Make sure that the flat gasket of the con-necting plate is correctly inserted.4The connecting plate has both NPT andG threaded bores. Seal the bore not re-quired with a rubber gasket and squareplug.Accessories:The switchover plate or con-necting plate must be ordered separately. Please note that actuators with modification index01e.g. 3277-531xxx20.01(old =.00) are equipped with new plates.Old and new plates are not interchangeable.Note!The pneumatic actuators are designed for a maximum supply pressure of 6 bar. To prevent the actuator from being dam-aged, do not let the supply pressure exceed the upper spring range value by more than 3 bar when the actuator is used forflow-switching service (on-off valve) with the fail-safe position "Actuator stem retracts". Label actuators that have a reduced supply pressure with a sticker "max. supply pres-sure limited to … bar".Note!Refer to the operating instructions of the corresponding valve on how to mount and remove the actuator from the valve.4EB8311ENDesign and principle of operationDesign and principle of operationEB8311EN52Operation Note!It is important for a trouble-free operation of the Type 3277 Actuator that the vent plug (3) is not blocked.Make sure in versions with a handwheel that the plug stem can move freely when the valve is being positioned by the pneumatic actuator by moving the handwheel into a neutral position.2.1Reversing the operating direction (fail-safe action)The operating direction, i.e. fail-safe action,of pneumatic actuators can be changed.Prior to proceeding, you must remove the actuator from the valve.The fail-safe action is represented by a sym-bol on the nameplate."Actuator stem extends""Actuator stem retracts"2.1.1Standard actuatorReversing the fail-safe action "Actuator stem extends" to "Actuator stem retracts"Note!Actuators with 700 cm² (travel = 30 mm)that are mounted to valves with 15 mm travel, are preloaded by approx. 75 % on mounting them to the valve.The signal pressure range is recorded on the nameplate when the actuators have been preloaded on mounting them to the valve.1.Unthread nuts and remove the bolts (9)from the diaphragm cases.2.Lift off the top diaphragm case (5) andremove the springs (6).3.Pull the actuator stem (2) with dia-phragm plate (7) and diaphragm (8) out of the yoke (10).4.Unscrew nut (1), while holding the nut(1.1) stationary or clamping the actuator stem with a suitable tool.Caution!Proceed carefully to avoid damaging the seals of the actuator stem.6EB 8311ENOperationCaution!Do not loosen the nut (1.1) on the actuator stem. It is painted over to protect it.If, however, it has been loosened, it is essen-tial that the dimension a(Figs. 3 and 4) measured from the top of the nut to the bot-tom of the actuator stem is kept.5.Apply lubricant/sealant (order no.8152-0043) to the sealing places on the actuator stem.6.Turn over top diaphragm case (5). Placethe actuator stem with diaphragm plate,diaphragm and metal plate (7.1), if ap-plicable in the case.7.Insert the springs (6) and slide the yokewith bottom diaphragm case over theactuator stem.8.Screw tight the nuts and bolts of the dia-phragm cases. Remove vent plug (3) inType 3277 Actuator.Proceed in the same manner for theType 3277-5Actuator intended for the mi-cro-valve, but additionally attach the bush-ing (2.1) for the mechanical travel stop. The springs now press from below against the diaphragm plate and cause the actuator stem to retract (fail-safe action). The actuator stem only starts to extend when the signal pressure overcomes the force of the springs.9.Record the changed fail-safe action onthe nameplate!Reversing the fail-safe action "Actuator stem retracts" to "Actuator stem extends"1.Unthread nuts and remove the bolts (9)and lift off the top diaphragm case (5).2.Pull the actuator stem with diaphragmplate, diaphragm and metal plate (7.1),if applicablethe diaphragm plate (7) outof the yoke and bottom diaphragm case(10).3.Unscrew nut (1), while holding the nut(1.1) stationary or clamping the actuatorstem with a suitable tool.Caution!Proceed carefully to avoiddamaging the seals of the actuator stem.4.Remove the diaphragm plate with dia-phragm and replace them in reverse or-der. Screw tight nut (1).5.Coat the sealing parts of the actuatorstem with sealant/lubricant (order no.8152-0043).6.Insert the actuator stem with diaphragmplate, diaphragm and metal plate (7.1),if applicable, into the bottom diaphragmcase with yoke.7.Insert springs (6) and place the top dia-phragm case back on.

气动驱动器种类及特点

气动驱动器种类及特点彭贺;刘洪波【摘要】As a new kind of bionic actuator,pneumatic actuators can be directly driven,with good flexibility,clean,little friction and simple structure.The advantages of the actuator have been concerned by domestic and foreign scholars and successfully applied to a variety of robots.This paper describes the classification and characteristics of pneumatic drives and a wealth of examples to illustrate.%气动驱动器作为一种新型的仿生驱动器,可直接驱动、具有较好的柔顺性、清洁、摩擦小、结构简单等优点得到了国内外学者的关注并成功应用到各种机器人上.本文主要介绍了气动驱动器的分类及特点并举例加以说明.【期刊名称】《吉林化工学院学报》【年(卷),期】2017(034)003【总页数】3页(P56-58)【关键词】气动驱动器;仿生;机器人【作者】彭贺;刘洪波【作者单位】北华大学机械工程学院,吉林吉林 132021;北华大学工程训练中心,吉林吉林 132021【正文语种】中文【中图分类】TH138.5传统的驱动方式主要是液压驱动和电机驱动[1],但随着新型技术和材料的不断涌现,出现了各种形式的驱动器,如:形状记忆合金驱动器[2]、磁致伸缩驱动器[3]、压电驱动器[4]和气动柔性驱动器等等.由于功能材料驱动因为成本高、技术尚不十分成熟,没有得到进一步的研究与开发.气动柔性驱动器以其结构简单、低成本、清洁无污染以及较好柔顺性等优点得到了广泛的应用[5].气动复合弹性体驱动器最早出现在上世纪50年代,经过几十年的发展,取得了丰硕的成果,目前,气动复合弹性体驱动器的种类主要有以下五种.1.1 McKibben型气动驱动器McKibben型PMA[6]作为最早的气动柔性驱动器,,其结构如图1所示,主要由三个部分组成:外层采用的纤维编织的刚性网、里层是弹性性能较好的橡胶管以及起到密封作用的上下连接件,其中一个连接件处设有充气口.图2十分清楚的解释了McKibben 型PMA工作原理,经充气口向橡胶管内注入压缩气体,随着气压的增加,橡胶管开始沿径向膨胀,径向膨胀力使得整个PMA 沿轴向收缩,与生物肌肉的工作方式类似.1.2 轴向伸长型的气动驱动器北华大学耿德旭教授等人研制了一种轴向伸长性的气动柔性驱动器,如图3所示.该驱动器主要由橡胶管、弹簧和上下端盖等组成,下端盖处设有气体入口.当向橡胶管内充入气体时,由于弹簧约束橡胶管的径向变形,该驱动器只能沿着轴向伸长,变形量与气体压力的大小成正比[7].1.3 弯曲型气动驱动器以色列海法大学Yoel Shapiro等人研制一种单自由度的弯曲型驱动器[8],该驱动器主要由非完全对称性的硅胶管、约束铁环,气体入口等组成,如图4所示.图中黄色部分为硅胶管,绿色部分为约束铁环,蓝色部分为气体入口.当向硅胶管内腔里充入压缩气体时,驱动器将朝着硅胶管壁厚的一侧弯曲.1.4 旋转型气动驱动器德国Karlsruhe研究中心也研制了一种回转型的气动驱动器,如图5所示.该驱动器主要由两个夹板和一个弹性气囊构成,两夹板通过铰链连接.当向弹性气囊内充入压缩气体时,气囊膨胀进而推动夹板张开一定的角度,张开角度的大小主要取决气囊的受压能力,受压能力越强,张角就越大.卸压后,驱动器在弹性气囊的作用下恢复到初始状态[9].1.5 三自由度PMA日本东芝公司(Toshiba)开发了一种具有三个自由度的气动柔性驱动器,如图6所示.PMA内腔是三个在圆周上均匀分布的气室,外层是管壁中加有纤维的橡胶管,两端为端盖.通过控制PMA三个气室里充入气体压力的大小,可使得PMA实现轴向伸长和空间内任意方向的弯曲运动[10].气动驱动器作为一种新型的执行元件,具有结构简单、易实现无级调速、易实现过载保护等诸多独特的优点将越来越广泛地进入工业、军事、航空等领域[11-12].但也存在一些缺点:(1)气动人工肌肉的变形为非线性大变性,准确控制其位移十分困难.因此若使气动人工肌肉实用化,还需要解决许多问题,例如研究简便通用的分析方法、简单高效的控制算法等.(2)气压驱动时需要稳定的气压源,如何实现轻量便携式的气泵是目前需要克服的难题,另外存在传输管路较长造成压力损失、噪音较大等问题.纵观近几十年气动驱动器的发展历史及研究现状,气动驱动器的研究还将朝着以下几个方向发展[13]:(1)建立更完善的理论模型,为性能优化和控制提供理论基础.(2)采用新型的气动驱动器,包括结构上的小型化、功能上的集成化以及材料上多样化等,而且必将带动相应元件的进一步发展.(3)应用范围将进一步扩大.在不久的将来,在医疗康复、娱乐、远程控制、虚拟现实等多领域将获得更广泛应用.综上分析,上述五种类型气动驱动器结构不同,实现的功能也不尽相同,但是它们的基本工作原理类似:皆以压缩气体作为系统的动力源,利用可膨胀的弹性气囊驱动,并在弹性气囊外部加以适当的约束进而控制其实现特定的运动.上述五种驱动器的弹性气囊皆由橡胶材料制作而成,气动柔性关节都是在上述五种驱动的基础之上,在结构上加以创新研制出来的.文章最后阐述了气动驱动存在的一些问题以及未来的发展方向.*通信作者:刘洪波,E-mail:*******************【相关文献】[1] 朱邦河.基于人工肌肉的仿生关节驱动器研究[D].郑州:河南工业大学,2014.[2] J.Abadie,N.Chaillet,C.Lexcellent.Modeling of a new SMA micro-actuator for active endoscopy applications[J].Mechatronics,2009,19:437-442.[3] Du Trémolet de Lacheisserie E.Magnetostriction:Theory and Applications of Magnetoelasticity [M].Boca Raton:CRC Press,1993.[4] Choi S B,Hong S R,Han Y M.Dynamic characteristics of inertial actuator featuring piezoelectric materials:experimental verification [J].Journal of Sound andVibration,2007,302(4):1048-1056.[5] B.Gorissen,R.Donose,D.Reynaerts.Flexible pneumatic micro-actuators:analysis and production [J].Procedia Engineering,2011,198(25):681-684.[6] 张远深,刘明春,赵娜,等.McKibben气动人工肌肉技术的发展历程[J].液压与气动,2008,32(7):13-15.[7] 张贵兰,耿德旭,刘晓敏,等.伸长型气动人工肌肉轴向力学特性分析[J]机械工程师,2012,8(12):7-8.[8] Yoel Shapiroa,Alon Wolfa,Kosa Gaborb.Bi-bellows:Pneumatic bending actuator [J].Sensors and Actuators A.2011,167(2):484-494.[9] 臧克江,顾立志,陶国良.气动人工肌肉研究与展望[J].机床与液压,2004,12(4):4-7.[10] Suzumori K,Maeda T,Watanabe H,et al.Fiberless Flexible Micro-actuator Designed by Finite-element method[J].IEEE/ASME Transactions on Mecha tronics,1997,2(4):281-286.[11] 郑永永,刘晓敏,赵云伟,等.基于正交试验设计的双驱动型单向弯曲关节结构参数的优化设计研究[J].吉林化工学院学报,2016,33(5):46-49.[12] 武广斌,郑永永,刘荣辉.气动双体人工肌肉弯曲特性分析[J].吉林化工学院学报,2016,33(7):41-43.[13] 陶国良,谢建蔚,周洪.气动人工肌肉的发展趋势与研究现状[J].机械工程学报,2009,45(10):75-83.。

气动执行机构俗称气动头又称气动执行器英文Pneumatic

气动执行机构俗称气动头又称气动执行器英文Pneumatic

⽓动执⾏机构俗称⽓动头⼜称⽓动执⾏器英⽂Pneumatic⽓动执⾏机构俗称⽓动头⼜称⽓动执⾏器(英⽂:Pneumatic actuator ) 执⾏器按其能源形式分为⽓动,电动和液动三⼤类,它们各有特点,适⽤于不同的场合。

⽓动执⾏器是执⾏器中的⼀种类别。

⽓动执⾏器还可以分为单作⽤和双作⽤两种类型:执⾏器的开关动作都通过⽓源来驱动执⾏,叫做DOUBLE ACTING (双作⽤)。

SPRING RETURN (单作⽤)的开关动作只有开动作是⽓源驱动,⽽关动作是弹簧复位。

⽓动执⾏机构简介⽓动执⾏器的执⾏机构和调节机构是统⼀的整体,其执⾏机构有薄膜式、活塞式、拨叉式和齿轮齿条式。

活塞式⾏程长,适⽤于要求有较⼤推⼒的场合;⽽薄膜式⾏程较⼩,只能直接带动阀杆。

拨叉式⽓动执⾏器具有扭矩⼤、空间⼩、扭矩曲线更符合阀门的扭矩曲线等特点,但是不很美观;常⽤在⼤扭矩的阀门上。

齿轮齿条式⽓动执⾏机构有结构简单,动作平稳可靠,并且安全防爆等优点,在发电⼚、化⼯,炼油等对安全要求较⾼的⽣产过程中有⼴泛的应⽤。

齿轮齿条式:齿轮齿条:控制精度较低,双作⽤的⽓动执⾏器,断⽓源后不能回到预设位置。

单作⽤的⽓动执⾏器,断⽓源后可以依靠弹簧回到预设位置⼯作原理说明班当压缩空⽓从A管咀进⼊⽓动执⾏器时,⽓体推动双活塞向两端(缸盖端)直线运动,活塞上的齿条带动旋转轴上的齿轮逆时针⽅向转动90度,阀门即被打开。

此时⽓动执⾏阀两端的⽓体随B管咀排出。

反之,当压缩空⽓从B官咀进⼊⽓动执⾏器的两端时,⽓体推动双塞向中间直线运动,活塞上的齿条带动旋转轴上的齿轮顺时针⽅向转动90度,阀门即被关闭。

此时⽓动执⾏器中间的⽓体随A 管咀排出。

以上为标准型的传动原理。

根据⽤户需求,⽓动执⾏器可装置成与标准型相反的传动原理,即选准轴顺时针⽅向转动为开启阀门,逆时针⽅向转动为关闭阀门。

单作⽤(弹簧复位型)⽓动执⾏器A管咀为进⽓⼝,B管咀为排⽓孔(B管咀应安装消声器)。

Principle of Operation:The need to control process and vent valves from a remote location makes air operated valves a vital component to many process applications.All Parker Autoclave Engineer’s needle valves are available with piston type pneumatic actuators. Six sizes of air actuators (light, mini-light, medium, heavy duty or extra heavy, single and double stage) are offered to meet the service requirements of Parker Autoclave Engineer’s Low, Medium and High Pressure needle valves. Both air-to-open (normally closed) and air-to-close (normally open) designs are included in the product line. Dual acting Air-to-Open & Close actuators are also available.For most Parker Autoclave Engineers valve series there is a choice of two or more actuator designs. This provides the most efficient and economical pneumatic valve operation for any combination of process requirements and available air pressure.Actuators are available for outdoor service. These operators provide corrosion resistant components and prevent the ingress of outside elements. Weatherproof or Explosionproof (CUL/A TEX) Limit Switch position indication is available upon request.Features and Benefits:• Fail Close (Air-to-Open) or Fail Open (Air-to-Close) with Spring Return• Dual Acting (Air-to-Open & Close) actuators are available in all sizes except Mini-Light and Light. Note: Not Fail-Safe • Piston actuator sizing incorporates maximum allowable air pressure of 100 psi• Y oke design for separation of process and air pressure/allows for limit switch position indication • Visual Valve Position Indicator as standard - Limit Switch options available • Anodized Aluminum Housing (for corrosion and wear resistance)• -20°F to 200°F (-29° to 93°C) ambient temperature range. (for operation below 30°F (-1°C) dry air must be used and heat tracing is recommended.)Needle Valve Actuators Pneumatic, Piston TypeFor: MVE, P , 10V , SW, SM, SC, V , VM, QS,Needle Valves to 150,000 psi (10340 bar)General InformationPneumatic Piston ActuatorsPneumatic Actuator:Six sizes of air operators (light, mini-light, medium, heavy duty or extra heavy, single and double stage) are offered for remote on-off operation or automatic operation of Parker Autoclave Engineer’s low, medium or high pressure valves. The actuators are available in air-to-open (normally closed) and air-to-close (normally open) designs. Remote On-Off:Parker Autoclave Engineer’s air-operated valves, ATO (Air-to-Open), ATC (Air-to-Close), or AOC (Dual Acting Air-to-Open & Close) pneumatic actuators can be controlled by a 3-way manual low pressure valve or by a 3-way low pressure solenoid valve mounted in the actuator supply air line. Parker Autoclave Engineer’s air-operated, high pressure valves permit process control from a remotely located panel without the necessity of piping high pressure lines to the control panel. Safety is greatly increased and process “hysteresis” is reduced. Prudent selection of ATO or ATC valves, together with the air controlling devices, permit the system design to “fail safe” in either the closed or open condition in the event of loss of air pressure, or electrical failure, or malfunction. Where explosion proof conditions are a requirement, pneumatic actuated valves can be considered. Remote mounting of the solenoid valve removes the potential from the hazardous area.Piston Type Valve ActuatorsPiston type air-operated valves offer a unique, reliable design providing for a long and dependable life. These actuators are quick acting, typically less than one (1) second activation time (Dependent on air flow rate to piston and process pressure required at valve inlet)) and long lasting (tested to over 100,000 cycles).Parker Autoclave Engineer’s piston type actuators feature:• Air-to-Open (Inlet Pressure may be required) or Air-to-Close with spring return or Dual Acting (no spring) Options • Anodized Aluminum Piston and Housing (100 psi max)• Yoke design for separation of process and air drive sections for safety †• Ease of stem replacement• Stem position indicator is standard†• High actuator cycle life with lifetime lubrication• 1/8” NPT air inlet connection except Extra Heavy duty has 3/8” NPT• Single or Dual (Open & Close) Limit Switch options are available in Weatherproof, Explosionproof(Class 1, Division 1, Groups C & D, Temp. Group T6) versions. Consult FactoryNote: Air supply to Air-to-Close Actuator must be regulated to the pressure shown in subsequent charts based on application pressure. Air pressure over required pressure may damage valve seat.A yoke design is available upon request.Note:See “Yoke Mounting Dimensions” on page 17 shouldthese mounting points be preferred instead of valvebody mounting holes.3 Actuator: Pneumatic Valve 02-0121SE 0719Technical DetailAir Operated Materials:Cylinder, piston, cover plates, spring housing: Anodized aluminum (for corrosion and wear resistance).Yoke: Painted SteelTechnical Data:Air Operator• Maximum allowable working pressure: 100 psi (6.89 bar)• Allowable piston temperature range: -20°F to 200°F(-29°C to 93°C), operating below 30ºF (-1.1ºC) with dry air only (heat trace may be needed for lower temperatures).• Area of piston:Light duty - 4.9 sq. in (31.6 sq. cm)Mini-Light duty - 5.4 sq. in (34.8 sq. cm)Medium duty - 19.6 sq. in (126.5 sq. cm)Heavy duty - 39.2 sq. in (252.9 sq. cm)Extra Heavy duty single stage - 56 sq. in (361.3 sq. cm)Extra Heavy duty double stage - 112 sq. in (722.6 sq. cm)• Approximate air usage/cycle @ 100 psi (6.89 bar) - For Dual Acting, double air usage shown below: Light duty - .003 SCF (.00008 SCM)Mini-Light duty - .007 SCF (.0002 SCM)Medium duty - .04 SCF (.0011 SCM)Heavy duty - .08 SCF (.0022 SCM)Extra Heavy duty single stage - .33 SCF (.0095 SCM)Extra Heavy duty double stage - .67 SCF (.019 SCM)• Tested to 100,000 cycles at 100 psi (6.89 bar) with no leakage or signs of wear or fatigue.To select Air-to-Close Needle Valve Actuator:Example:Need to know: Valve Model/Connection Size - 20SM9071 Needle ValveIndoor or Outdoor Service - Outdoor ServiceMaximum Operating Pressure: Fluid - 12,000 psiMaximum Available Air Pressure - 60 psiSelect Actuator Type : Air-to-Close type (Normally Open)Example: Using chart on page 6 (Air-to-Close Actuators), select 20SM9 SectionAcross top of chart, select 12 Ksi System Pressure (12,000 psi max system pressure)Go down that column to 20SM9Section to first row filled with number (air pressure)First row with number is 55 – as your available air pressure is 60 psi, you do not have to go any further (if this number was more than 60, continue to next row)This row (Heavy Duty Actuator) confirms that this actuator needs 55 psi to close the 20SM9 valve at 12,000 psi and you have 60 psi available. Suffix code for this actuator can be found in this chart or on page 4 - find “Heavy Duty - Air-to-Close” - Suffix code is “-C2SOD”, remembering the Service location was “Outdoor” - add this suffix to the 20SM9 body style of your choice.

Pneumatic Actuators1 IntroductionPneumatic actuators are devices in which energy of compressed air is utilized for carrying out mechanical work like linear, rotary, and oscillatory movement. The most commonly applied actuator is the pneumatically driven actuator, because the power source-compressed air-is relatively inexpensive compared to electrical or hydraulic power sources. For that reason, approximately 90 percent of all actuators in service today are driven by compressed air. When compared to the cost of electromechanical and electrohydraulic actuators, pneumatic actuators are relatively inexpensive as well as easy to understand and maintain. Most are available as standard off-the-shelf products in a number of predetermined sizes corresponding to maximum thrust. Only in special services are special-engineered actuators produced, such as applications requiring exceptionally long strokes, high stroking speeds, or severe temperatures. From a maintenance standpoint, pneumatic actuators are more easily serviced and calibrated than other types of actuators. Some pneumatic actuators are designed to be field-reversible, meaning that they can be converted from air-to-extend to air-to-retract (or visa versa) in the field without special tools or maintenance procedures.2 Features of Pneumatic ActuatorsIn general, essential systems for power transmission in machineries are pneumatic, hydraulic, electric, and mechanical. By making comparisons with these systems, the features of the pneumatic actuators can be enumerated as below:(1) Compared to hydraulic systems, pneumatic systems are more suitable for light and medium loads. In reciprocating air compressors, since the discharge pressure at the first and the end stage are 600~700 kPa and 1200~1400 kPa respectively, the air pressure mostly utilized is below 1000kPa. As pressure higher than this, the efficiency suffers, and its use become difficult as the system has to conform to the applicable rule requirements for high-pressure gas.(2) The best feature of compressed air is that, by utilizing the compressibility characteristics of air, energy can be stored in the form of pressure in air tanks. This can be used for high-speed operations or emergency operations during power failures.In addition, during the momentary air consumption of the pneumatic machine, even if it exceeds the discharge volume of the air compressor, work greater than the capacity of the air compressor can be done with the provision of air tanks etc provided that the average air consumption (value obtained by dividing the total consumed by the sum of the operating and idling time of the air compressor) is not exceeded.(3) Control of position and speed is difficult due to the compressibility characteristics of air.(4) Due to various losses involved, the overall efficiency of the pneumatic actuator, in comparison with the other systems is low. In an air compressor, theoretical work is done in adiabatic compression but the volume gets reduced when the compressed air is cooled. Moreover, there is pressure loss when compressed air is sent to the pipings and the control valves and form the air tank and in addition if it is assumed that there are leakages on the way then there is reduction in its volume by the time it reaches the pneumatic actuator. If the pneumatic actuator is of the complete-expansion type, the work done can be effectively used in a non-expansion type, this degree of advantages is further reduced.(5) Due to the compressibility characteristics of air, no surge pressure similar to that which occurs in the hydraulic system is generated which obvious the necessity of overload preventiondevice in the system, and also the mutual interference between the machines due to the surge pressure is low.Furthermore, as the output in the pneumatic actuator does not exceed the theoretical output, it is safe. This allows the theoretical output to be calculated from the useable air pressure only without taking into account the surge pressure.(6) Piping is easier than in the hydraulic system and also no environmental pollution problem or fire risk due to external leakages.(7) Pressure loss is small, because inertia and viscosity of the air are small compared to the hydraulic fluid. Air can be piped to each and every part of the factory and used readily. The maintenance is also easy.(8) It has a large range of practical application because it can be adopted for wide range of temperature, vibration and combustion environments.The useable temperature is rather wide, -40 to 200 and thus especially suitable where consideration in the specification must be given to prevent freezing of moisture contents and use of seals and electrical parts at low temperatures.(9) Pneumatic actuators have no fire hazards and are made of explosion proof construction.(10) It is easy to convert electrical signals to pneumatic, pneumatic to hydraulic, and pneumatic to electrical signals. As opposed to the response in electrical signal systems, it is inferior for the control elements in the pneumatic systems.3. Two Kinds of Pneumatic ActuatorsThe most commonly applied pneumatic actuator over the past 40 years has been the diaphragm actuator (See Figure 7.5). Most diaphragm actuators are designed for linear motion, although some rotary-motion designs exist. By definition, a typical diaphragm actuator is a single-acting actuator that provides air pressure to one side of an elastomeric barrier (called the diaphragm) to extend or retract the actuator stem, which is connected to the closure element. The diaphragm is sandwiched between upper and lower casings, either of which can be used to hold air pressure, depending on the style of the actuator.Diaphragm actuators have both direct-acting designs. With the direct-acting design, air pressure is sent to the actuator, which extends the actuator stem and allows the value to close. This also means that the actuator will retract its stem upon loss of air, allowing the value to open and remain open. With the reverse-acting design, as the air pressure is sent to the actuator, the stem retracts and the value opens. If the supply or signal air pressure is interrupted, the actuator moves to the extended position, allowing the value to close.The chief advantage of diaphragm actuators is that they are relatively inexpensive to produce and are commonly seen through the entire process industry. Although limited in high-thrust requirements, they are well suited to a good portion of applications in lower-pressure ranges, where thrust requirements are not so demanding. On the other hand, diaphragm actuators —because of the limitations of the diaphragm — do not provide exceptional stiffness and therefore have problems with fluctuations in the process flow. They also experience problems when throttling close to the seat, not having enough power to prevent the closure element from being pulled into the seat. The stiffness value of a diaphragm actuator is usually constant throughout the entire stroke. When the closure element is close to the seat, a sudden change or fluctuation in the process flow can cause the valve to slam shut, causing water-hammer effects.From a maintenance standpoint, the life of diaphragm actuators is somewhere limited by thelife of the diaphragm. If the diaphragm develops even a minor failure, the actuator is inoperable. Since the two casings are bolted together with numerous bolts, disassembly can be somewhat laborious and time consuming. Diaphragm actuators are not field-reversible, because different parts are required for the direct and reserve-acting designs. Diaphragm actuators have about one-third more parts than other types of pneumatic actuators, which increasing their cost somewhat.Although the diaphragm actuator is the most common pneumatic actuator, the piston cylinder actuator (See Figure 7.6) is gaining widespread acceptance, especially as processes become more advanced and demanding. The piston cylinder actuator uses a sliding sealed plate (called the piston ) inside a pressure-retaining cylinder to provide double-acting operation. With the double-acting design, air is supplied to both sides of the piston by a positioned. As with all double-acting actuators, a positioner must be used to take the pneumatic or electric signal from the controller and send air to one side of the piston while bleeding the opposite side until the correction position is reached. An opposing range spring is not necessary with the piston cylinder actuator, although a spring may be included inside the cylinder to act as a fail-safe mechanism.Like diaphragm actuator designs, piston cylinder actuators can be used with either linear or rotary valves. Linear designs are the most efficient since the entire movement of the actuator stem is transferred directly to the valve stem. On the other hand, the rotary design must use some type of linear to rotary-motion linkage. This can create some hysteresis and dead band v\because of the lost motion caused by the use of linkages of slotted levers.The primary advantage of cylinder actuators is the higher thrust capability, size for size, over comparable diaphragm actuators. Because the cylinder actuator with a positioner does not need to use air supply as a signal, the plant’s full air-supply pressure can be used to power the actuator. The piston with its sliding O-ring seal is much more capable of handing greater air pressure than the diaphragm. Piston actuators, which have smaller chambers to fill with higher pressure of air, have faster stroking speeds than diaphragm actuators, which must fill larger chambers with lower pressure of air, piston cylinder actuators are much more compact, being smaller in height and weight, than diaphragm actuators —an important consideration with installation, maintenance, and seismic requirements.Piston cylinder actuators have some drawbacks. First, if the actuator remains in a static position for some time, some breakout force may be necessary to move the piston when a signal is eventually sent. When considering the added thrust and response associated with piston cylinder actuators, this breakout torque may not be noticeable. The requirement of a positioned does add expense to the actuator—although with less parts, the actuator itself is less expensive than a diaphragm actuator. A positioned also requires calibration.。
