执行机构基本工作原理（一）1

执行机构基本工作原理（一）1执行机构基本工作原理（一）——执行机构发展史一、执行机构的由来执行机构，又称执行器，是一种自动控制领域的常用机电一体化设备（器件），是自动化仪表的三大组成部分（检测设备、调节设备和执行设备）中的执行设备。

主要是对一些设备和装臵进行自动操作，控制其开关和调节，代替人工作业。

按动力类型可分为气动、液动、电动、电液动等几类；按运动形式可分为直行程、角行程、回转型（多转式）等几类。

由于用电做为动力有其它几类介质不可比拟的优势，所以电动型近年来发展最快，应用面较广。

电动型按不同标准又可分为：组合式结构和机电一体化结构；电器控制型、电子控制型和智能控制型（带HART、FF协议）；数字型和模拟型；手动接触调试型和红外线遥控调试型等。

它是伴随着人们对控制性能的要求和自动控制技术的发展而迅猛发展的：1．早期的工业领域，有许多的控制是手动和半自动的，在操作中人体直接接触工业设备的危险部位和危险介质（固、液、气三态的多种化学物质和辐射物质），极易造成对人的伤害，很不安全；2．设备寿命短、易损坏、维修量大；3．采用半自动特别是手动控制的控制效率很低、误差大，生产效率低下。

基于以上原因，执行机构逐渐产生并应用于工业和其它控制领域，减少和避免了人身伤害和设备损坏，极大的提高了控制精确度和效率，同时也极大提高了生产效率。

随着电子元器件技术、计算机技术和控制理论的飞速发展，国内外的执行机构都已跨入智能控制的时代。

二、执行机构的应用领域执行机构主要应用在以下三大领域：1、发电厂典型应用有：火电行业应用送风机风门挡板、一次进风风门挡板、空气预热风门挡板、烟气再循环、旁路风门挡板、二次进风风门挡板、主风箱风门挡板、燃烧器调节杆、燃烧器摇摆驱动器液压推杆驱动器、叶轮机调速、烟气调节阀、蒸气调节阀、球阀和蝶阀控制、滑动门、闸门;其它电力行业的阀门执行器应用球阀、除尘控制喷水、叶轮机转速控制、控制大型液压阀、燃气控制阀、燃烧器点火启动、蒸气控制阀、冷凝水再循环, 脱氧机，锅炉给水，过热控制器，再加热恒温控制器，及其它相关阀门应用2、过程控制用于化工、石化、模具、食品、医药、包装等行业的生产过程控制，按照既定的逻辑指令或电脑程序对阀门、刀具、管道、挡板、滑槽、平台等进行精确的定位、起停、开合、回转，利用系统检测出的温度、压力、流量、尺寸、辐射、亮度、色度、粗糙度、密度等实时参数对系统进行调整，从而实现间歇、连续和循环的加工过程的控制。

TO RESTORE THE VALVE CONTROL FUNCTION (29)14. BATTERY MAINTENANCE (29)1.FORWARDThe Line Break Detection System type ELBS-10 is an electronic equipment, developed by Biffi,for monitoring the pipeline integrity. The ELBS-10 continuously monitors the pressure in the line and in case of failure, it sends a command to the actuator so as to stroke the line valve to the fail safe position. The electrical power necessary for working, is supplied by a 7.2V lithium battery pack that allows the ELBS-10 to work for at least one year.The ELBS-10 is provided with a powerful local operator interface, made of one 2 lines / 16characters LCD display and 3 push-buttons, that allows to enter the configuration data and to visualise the values of variables or the status of the device. Moreover an RS232 serial communication port is provided for connection to a PC or LAP TOP, to carry out parameter configuration, or variables visualisation or to down-load the recorded event data for further analysis of pipeline behaviour .The ELBS 10 was especially engineered for “ON FIELD” service, it means capability of working in the severest ambient conditions, as wide operating temperature range, vibrations, explosive atmosphere, etc. Particular care was taken to increase the level of immunity against the radio frequency disturbs.2.WORKING PRINCIPLEThe ELBS-10 samples cyclically the line pressure value, measured by the pressure transducer (PT) and memorises the sampled values in a temporary rolling memory, type FIFO (First in, First out). The rolling FIFO memory allows to store 256 samples and the sampling rate is programmable from 1 to 10 s.The pressure magnitude and pressure drop rate are continuously compared to the reference values, set by the user in the configuration memory.An event is defined as the condition that occurs when the measured pressure magnitude or pressure drop rate exceeds the customer set-point for a configurable time.In case of event, the pressure magnitude values, present in the FIFO memory and relevant to 88 samples preceding the event and 168 samples after the event, are transferred to the “data memory”. Only one sample out of four is stored in the event data memory. So each event is recorded in the event data memory by 64 samples(22 samples preceding the event and 42 after the event).The event data memory can store up to 1000 events.The following drawing shows the block diagram of the ELBS-10:The ELBS-10 transfers into the “event data memory” the following type of EVENTS: EVENT 1- pressure value decreases of a pre-set amount (field configurable )EVENT 2- pressure reaches the low value limit (field configurable)EVENT 3- pressure value increases of a pre-set amount (field configurable)EVENT 4-pressure reaches the high value limit (field configurable)EVENT 5- (only in ACQ mode) pressure drop exceeds the pre-set speed dropdata acquisition (field configurable)EVENT 6- pressure drop exceeds the pre-set speed drop valve control (field configurable) The following configurable operating mode are available:•data acquisition•valve control•sleepIn data acquisition operating mode the pressure samples relevant to an event (1,2,3,4,5) are stored in the data memory but an event does not affect the valve position.In valve control operating mode the pressure samples relevant to an event (1,2,3,4,6) are not stored in the data memory but EVENTS 2 ,4 and 6, cause the valve to stroke to the fail-safe position.The two operating mode can be used separately or simultaneously. In valve control + acquisition mode (ACQ+VC ), in case of pressure drop only EVENT 6, EVENT 1, 2,3,4 are recorded, while EVENT 5 is not recorded.The sleep operating mode is used to inhibit both data acquisition and valve control operating modes to puts out of service the ELBS-10.In case of alarm or if valve control mode is chosen but the solenoid valve control is ‘’not armed‘’, automatically, the ELBS-10 enters in the ‘’ slow sampling ‘’ state. In the above state the valve control and acquisition functions are off, but the ELBS-10 restores to normal operation when the cause disappears.The following figure shows the ‘’ data acquisition area ‘’ in function of the time.The below figure shows the above described types of EVENT that could be memorised during one year of pipeline data acquisition.The Event 1, happened in January, represents a pressure that pass through the values of 30 bar and 25 bar, causing the memorisation of the events in the “event data memory” ( Event 1.1 & Event1.2).In February, April, May, July September and November the pipeline pressure does not generates any Event. The Event 3 represents a pump station start-up, while the Event 5 is a pump station shut down that creates a pressure drop rate higher than the ELBS-10 adjustment, so that the Event 5.1,5.2, 5.3 and 5.4 are memorised into the “event data memory ’’. The Event 6 represents a Line Break that creates a pressure drop rate higher than the pipeline curve behaviour present in the ELBS-10memory. In this case the actuator is controlled in order to stroke the pipeline valve in the fail position.Pressure behaviour relevant to one year51015202530354045505560657075Pressure (bar)All the Events are memorised in the “event data memory”. The following formula allows to calculate the duration of the recorded time corresponding to each event and the time between two recorded pressure data in each event:recorded time duration ( min. ) = sampling rate * 256 / 60 time between 2 data ( sec. ) = sampling rate * 4For example with sampling rate at 8 sec. the time duration of the recorded data is 8*256/60 = 34.1min, and the time between two recorded pressure data is 8*4 = 32 sec.When the “event data memory” reaches 90% of its capability an alarm informs about the need to discharge the memory content in a portable PC in order to allow the ELBS-10 to restart its pipeline survey.The content of the “event data memory” can be used to build-up the pipeline pressure curve relevant to one year of survey, as shown in the below figure.The pressure curve allows to calculate the typical values of pressure and pressure drop rate of the pipeline and to enter the correct set-points in the ELBS-10 .Pressure curve obtained after one year of survey5Pressure (Bar)September2.1. Table of operating modesOperating mode DescriptionValve Control ( V C ) (configurable)No data acquisition, only valve control in case of EVENTS 2,4, 6.Valve control mode is active only if ‘’Solenoid valve control’’ is ‘’armed‘’. The ELBS-10 switches to slow sampling mode if :- solenoid valve control is not armed.- if there is an alarm.- after the valve control.Acquisition ( ACQ ) (configurable)Valve control not active.No valve control, only data acquisition on EVENTS 1, 2, 3 , 4, 5. The ELBS-10 switches to slow sampling mode if :- the event data memory is full and ‘’ not circular mode ‘’ is set. - if there is an alarm.- in case of low pressure (EVENT 2).- in case of high pressure (EVENT 4).Valve Control + Acquisition ( V C + ACQ ) (configurable)Valve control on EVENTS 2, 4, 6, and data acquisition on EVENTS 1, 2, 3, 4, 6.Valve control + Acquisition is active only if ‘’Solenoid valve control’’ is ‘’armed’’.The ELBS-10 switches to slow sampling mode if :- solenoid valve control is not armed.- if there is an alarm.- after the valve control.If event data memory is full and ‘’ not circular mode ‘’ is set, the data acquisition stops, but valve control is still active.Sleep ( SLEEP ) (configurable)No data acquisition and valve control.No pressure and voltage measurement.The local operator interface is still available.Slow sampling ( SLOW ) (automatic, not configurable)No data acquisition and valve control.The local operator interface is still available.The ELBS-10 measures the voltage supply and the pressure with a time equal to ‘’slow sampling rate’’ (see: parameters and set-points list). The ELBS-10 display show ' SLOW' The ELBS-10 restores to normal operation when the cause disappears.3.GENERAL CHARACTERISTICS3.1.Valve control on pressure drop rateWhen the pressure drop rate exceeds the drop rate set-point(EVENT 6), the ELBS-10 sends an electric command to the solenoid valve and the actuator stroke the line valve to the fail position.3.2.Valve control on high or low pressureThe ELBS-10 sends an electrical signal to the solenoid valve in order to stroke the line valve to the fail safe position when the pressure value is lower than the low pressure set-point ( EVENT 2 ), or is higher than the high pressure set-point ( EVENT 4).3.3.Valve control for simulation testThe ELBS-10 is fitted with an hardware/software module that allows to enter a pressure drop rate in place of the pressure transducer values, in order to verify the output command signal to the solenoid valve and the correct operation of the device.The test function force the valve control (VC) mode . The simulated pressure will start to the high pressure limit and goes to 0 bar. The test function can be stopped by the ENTER push button. If the ELBS-10 will close the pipeline valve the event will not be recorded.3.4.Valve control delayThe ELBS-10 is fitted with a configurable time delay module that allows to delay the solenoid valve command. If the condition which causes the event (low pressure EVENT 2, high pressure EVENT 4, pressure drop rate EVENT 6), disappears during the delay time, the valve control signal will not be generated .3.5.Line pressure data acquisitionThe ELBS-10 temporary rolling memory (FIFO) is continuously recording 256 samples. When an event occurs, the FIFO memory data are stored, one out of four, in the event data memory. The event data memory capacity is of 1000 events. The following set-point are used : low pressure set-point (EVENT 2), high pressure set-point (EVENT 4), drop rate set-point in valve control mode (EVENT 6), pressure drop rate set-point in acquisition mode (EVENT 5), pressure increases of pre-set amount (EVENT 3), pressure decreases of pre-set amount (EVENT 1).When more events occur during the data acquisition, the relevant event record will be marked whit the code of the first one.The data relevant to the events can be visualised by local operator interface or by PC via RS232 serial line. By PC, the user can built-up the line pressure behaviour.3.6.Solenoid valve control outputThe ELBS-10 is provided with a 24Vcc/100mA output electric signal and one change-over dry contacts of a relay, suitable to drive the solenoid valve of the actuator.A timer module allows to set the duration of the solenoid valve control (solenoid control duration ).The output is active if the ELBS-10 operating mode is valve control (VC ) or valve control +acquisition (VC+ACQ ) and ‘’solenoid valve control ’’ is armed .3.7.Power supply packIn this case the ELBS-10 is fitted with a battery pack with 4 x 3.6V Lithium Thionyl Chloride, size D. The battery pack is installed in an explosion proof enclosure. The battery service life depends on the sampling rate. By selecting 8 sec. as sampling rate the minimum battery life is 1 year. A battery life survey function generates a Warning signal when the next change of battery is necessary ( see next maintenance on tab. 7.1).3.8.Local operator interfaceThe ELBS-10 is fitted with a 2 lines / 16 characters LCD display and 3 push-buttons that allows to enter the configuration parameters or to visualise the working data.Two push-buttons 'DEC', 'INC' are used to move into the menu, while the third 'ENTER' is used to enter the selected information.To visualise the messages of the display, the operator can choose between two available languages (English or Italian). The following operations can be done:• to visualise the:-event data memory content -pipeline present pressure value -line valve control set-points -data acquisition set-points -battery voltage value-status and alarm of the ELBS-10The configuration operation are protected by password . The operator can enter in the configuration menu and change the parameters or arm the solenoid valve control output, only after entering the appropriate password . The ELBS-10 is supplied by BIFFI with the default password ‘’ 0000 ‘’. The customer can enter its own secret password of 4 alpha-numerical characters. When the newpassword is entered, the default one is no longer valid.3.9.Local communication portThe ELBS-10 when is connected via RS232 to a portable computer it is possible to control and program all relevant parameters. The following operations can be done:•to visualise the:-event data memory content-pipeline present pressure value-line valve control set-points-data acquisition set-points-battery voltage value-status and alarm of ELBS-103.10.Output relaysOne output relay with change-over, dry contacts is available for remote signalling of alarm of ELBS-10. In alarm the ELBS-10 stops working. (see: alarm and warning table ).One output relay with change-over, dry contacts is available for remote signalling of warning of ELBS-10. In warning all functions of the ELBS-10 are available, but some parameter or variable is not correct (see alarm/ warning table).One output relay with change-over, dry contacts is available for remote signalling of solenoid valve control not armed. When the status of the relay indicates ‘’armed’’, the ELBS-10 is ready to control the valve if the pressure is lower than the set-point, or the pressure is higher than the set-point or the pressure drop rate exceeds the set-point (EVENTS 2,4,6), when one of this events is detect the ELBS-10 command the line valve to fail position and switch this relay. After valve control the relay remains in the status ‘’not armed ‘’. This relay will be reset when the ELBS-10 is re-ARMED. (see : how to arm solenoid valve control par.).3.11.Pressure transducerThe pressure transducer is supplied with the ELBS-10 and is installed on the line valve at valve maker / customer care, according to Biffi instructions.The pressure transmitter must be installed downstream the line valve and converts the pipeline pressure 0-100 bar to a0-20mA electrical signal.3.13. Example of pressure drop rate controlThe following figure shows the ELBS-10 behaviour in presence of a continuous pressure drop rate.Note : Before than the valve control action takes place, it needs that the EVENT 6 condition is confirmed for the “confirmation time” and the pressure decreases during the “delay” time.The following figure shows the ELBS-10 behaviour in presence of a temporary pressure drop rate.4.ELBS-10 ELECTRONIC CARDSThe ELBS-10 consists of two electronic card ( mother board and display board). On the mother board are located the microprocessor, the A/D converter, the memories, the power supply stage and the input / output modules.

气液联动执行机构工作原理

气液联动执行机构工作原理
气液联动执行机构是一种机电液一体化的执行机构，它是利用气压或液压作为动力源，通过压缩空气或液压油推动活塞运动，从而实现力的传递和执行工作。

其工作原理主要涉及气源供给、气路和液路控制以及执行元件等几个主要方面。

1.气源供给：气液联动执行机构的气源通常通过压缩空气来提供。

压缩空气经过压缩机压缩，经过除尘、干燥等处理后，储存在气体容器中。

气源管路通过减压阀将高压压缩空气调整为机构所需的工作压力。

2.气路控制：气路控制主要包括控制阀及相关元件。

气路控制的主要功能是控制气压的开关和调节，使其能够传递到执行元件，从而实现执行元件的运动。

气路控制主要包括节数、单通、多通、双控和单控等。

3.液路控制：液路控制主要是指对液压油的流动进行控制。

液路控制主要包括液压阀、软管、滤油器、油箱等元件。

液路控制主要通过油泵将液压油送入液压缸，从而推动活塞运动。

液压缸的运动由液压阀来控制流入和流出的液压油量，从而实现对执行元件的控制。

4.执行元件：执行元件是气液联动执行机构的重要组成部分，主要由气缸、液压缸以及执行元件本身所组成。

气缸通常通过气路控制，将压缩空气传递到活塞上，从而推动活塞运动。

液压缸则通过液路控制，将液压油传递到活塞上，从而实现力的传递和执行工作。

气液联动执行机构的工作原理可以简单概括为：通过气源供给的压缩空气或液源加以控制，推动执行元件的活塞运动，从而实现力的传递和执行工作。

它具有结构简单、运动平稳、工作可靠等特点，在自动化生产中广泛应用于机械、冶金、石油化工、航空航天等行业。

国内市场主流电液执行机构介绍

国内市场主流电液执行机构介绍鞍山远航摘要：本文就截止至2013年8月，笔者所了解的国内市场上的各品牌电液式执行机构做以简单介绍。

说明：笔者的专业是工业自动化仪表，从事本专业工作近20年，本文内容仅代表一个专业技术人员的个人观点，无意褒贬任何企业或产品。

1.概述：最近几年，由于液压技术、计算机技术、电子技术和控制技术的发展，传统液压站式分体的电控液压系统已经落伍，取而代之的是一体化的电液式执行机构（下文中均简称电液）。

这种一体化的电液将传统的液压、传动和控制部分集中为一体，体积大幅减小的同时，又很好地解决了防护与防爆的问题，不仅使得安装、操作和维护都变得更加方便，故障率明显降低，也使其能够适用于流程工业的大多数工况。

在要求大扭矩操作、高品质控制和快速运转的工艺场合，以呈现出替代电动执行机构和气动执行机构的趋势。

2.历史：最早进入国内市场，也是笔者最早听说的电液品牌是美国瑞克萨（REXA），据说是由无锡工装引进，但作为探路者，瑞克萨付出了巨大代价，终因漏油问题一直不能很好解决，而没能在国内占有足够大的市场份额。

2010年初，德国莱纳克（Reineke）和韩国阿匹玛（RPM）的电液在国内强势出场，笔者也有幸与两个品牌深入合作，一直到莱纳克重新定位于高端市场，阿匹玛则因为总代理另起炉灶而淡出。

2011年笔者在鞍山工装看到了日本工装（KOSO）电液样机，但当时还没有系列化，也没有防爆产品。

到2012年，鞍山工装利用其3610系列电子式电动执行机构在国内成熟的销售渠道，将其电液迅速推广。

应业主要求，笔者也与工装进行了多次合作。

韩国世专（VALMAC）于2012年在很短的时间内推出全系列电液产品，这得益于其研发团队正是来自于慢慢淡出市场的韩国阿匹玛（RPM）。

这个团队在总结了阿匹玛产品2年的现场应用中发现的问题，进行了全面的改进升级，之后重返国内市场，参与角逐。

3.对比：笔者未曾与美国瑞克萨（REXA）进行过任何方式合作，对其性能没有掌握第一手资料，因此，本文不对该品牌深入介绍。
