Characteristics

The valve electronics described in this documenta-tion relates to the control of high response direc-tional control valves with solenoids, series D**F . The electronics is an integrad part of the valve, unifying various functions necessary for the opti-mum usage of the valve and leading to an inte-grated solution. The result is an outstanding dy-namic response, permitting the valve to be used in closed loop controls. The integrated electronics carry out the following functions:

? Provides a specially designed output power stage for high dynamic control of the solenoids ? Constant current control of the solenoids ? Overriding main stage stroke control

? Specially developed position transducer for high resolution high dynamic control ?

Power Supply

The utilized power supply has to comply with the EMC-standards (CE-sign, certi?cate of conformity). Parker is offering the following power supplies:Relais and solenoids operating from the same supply circuit as the valve electronics has to be ?tted by surge protection elements.Wiring Cable The wiring cable between the control cabinet and the valve has to be shielded. The central wiring has

to be installed from a 7wire cable that utilizes a common shielding and a cross section of min. AWG17. The capacity should not exceed a value of approx. 130pF/m (wire/wire). The maximum cable length is 50m. No power current lines may be placed in parallel to the valve′s wiring cables. The cable shield has to be connected to earth ground at both ends (see also chapter “Ground-ing“). Please be aware of ground-loops.INSTALLATION GUIDE

TO PROVISION OF ELECTROMAGNETIC COMPATIBILITY

Connectors

The central connection of the valve electronics needs a connector 6pin+E according EN 175201-804 featuring metal case and integrated cable shield coupling. Parker can provide suitable connectors:5004072 (Connector 6pin+E)The connectors have to be installed according the

connection diagram, the cable shield has to be tied

on the whole periphery to the provided coupling clamp.Grounding

The mounting plate of the valve has to be con-nected to the grounded metal machine frame. The Earth wire to pin G of the central wire cable as well as the cable shields of the valve connection cables should be tied to earth ground at the control cabi-net. A low-ohmic potential compensation wire has to be provided between the control cabinet and the machine frame (cable wire >AWG7 cross section)

to prevent ground loops.

The connecting cable has to comply to the follow-ing speci?cation:Cable type control cable, ?exible,

Signal-Input

The command signal input of the valve has been wired from the connector terminals D and E to the differential input of the onboard electronic. The valve stroke is acting proportional to the value of the signal. According to the valve model there are different command signal options available, which are separately described below. More details are obvious from the technical data. The input signal must be ?ltered as well as free of surges and

modulations. Due to the resolution sensitivity a high signal quality is recommended, to avoid function disturbances.

Improper high signal amplitudes may lead to function disturbances or damaging depend-ing of the exceeding value.

The explanation of functionality assumes junction E as point of reference potential.

Wiring example of voltage input option +10...0...-10 V

Wiring example of current input option 4...12...20 mA

Wiring example of current input option +20...0...-20 mA

Command signal option 4...20 mA uses the “0 mA“ - condition as failure information. This means that an evaluable failure information is provided for an interrupted command signal circuit. In the present case the solenoid drive thereby will be switched off.

The drive will be activated if the input signal ex-ceeds a value of 3,8 mA and will be disabled below 3,6 mA. This de?nition follows the NAMUR standard NE43.

Min/Max-Setting

The min/max-setting option achieves a conditioning of the valve operating range to a certain application.The min-setting is used for valves with overlapped main spools, it compensates for the mechanical overlap by an offset-feature.The max-setting limits the stroke of the valve spool, equally the full input signal range will be preserved and can be used with full resolution.

Both settings are provided separately for both valve operating directions.Diagnostic Output T o make available measurements for the momen-tary position of the valve spool the valve electron-ics unit provides a diagnostic output. This is avail-able at the main connector between pin F and supply zero (pin B) as well as on the printed circuit board of the valve electronics unit which provides

two diagnostic sockets. The sockets take 2mm plugs and can e.g. be used in the setting up of the zero point.The output is a 0...±10V signal where the value of 10V normally represents the maximum permitted stroke of the valve spool.The diagnostic output is short circuit proofed and is fully operative up to a load of at least 2kOhms or 5mA.Position Control The purpose of the position controller is to compare the actual value of the spool as given by the valve electronics sensor with the set value and provide signals to the actuating solenoids to ensure that the set position is achieved and maintained. The sketch below shows the operating principle of the control circuit.

Power Stage

In the output stage the output signal of the position controller is converted into an activating signal for the operating solenoids.

Keeping the power relationships at the solenoid constant as well as the need for rapid excitation of the solenoids is achieved with controlled current from a constant current control stage.The solenoid

current is measured in the valve electronic unit and compared with the set-value for current in the

constant current controller. As long as there is a difference between set and actual current values

the output stage will change the solenoid current

in order to equalise them.The solenoid also has a superimposed dither signal which has been care-fully matched with the mechanics of the valve to compensate for mechanical friction so that the hysteresis will not in?uence the dynamics of the valve.Enable Signal Input

To switch-off the output stage the valve electronics unit is ?tted with an enable signal input which can

at any time be used to interrupt the solenoid current irrespective of transducer signal or set value. In this case the main spool takes up - without any delay - the spring centered position in the valve.

A further function of the enable signal input is to limit the output of the position control. Normally on

switching off the activated solenoid the output of

the controller would be driven into saturation by the Integral part of the PID system. Because of this, if the solenoid is immediately switched on again the valve spool is for a short period of time operated inde?netily. To avoid this, the integral part of the controller is switched out and a limit is placed on the controller output for as long as the enable input

is switched off. When the enable signal is switched on again the valve spool will immediately move from it's central position and take up the required set position.

The enable signal input is, as far as circuitry is concerned, completely isolated from the rest of the electronics to keep interference from peripheral equipment away from valve electronic unit. It re-quires a signal in the region of 5 to 30VDC with a current supply of about 10mA. The enable signal is fed into the unit via the central connector between pins B and C.

5. Measuring Points Note

Position Of The Measuring Points

The enable signal should preferably be switched off together with the hydraulic pressure source in order that the solenoid spools have no circulating current when the hydraulic system is switched off. This reduces energy loss and unnecessary heat generation in the solenoid spools.Note

The enable signal does not provide security against unwanted operation of a valve in the sense of the

accident prevention regulations. To block all pos-sibility of a valve functioning under any circum-stances, further steps are necessary, e.g the ?tting of safety lock valves.

Voltage Monitor

The supply voltage may therefore lie between 18 and 30V , with a ripple of no more than 5%. These voltages are valid on load i.e. with valve electronics and enable signal connected.

The value of the supply voltage is supervised by an integrated voltage monitoring.

Control Failure Monitor

If a failure >2% occurs within the position control loop of the valve a control failure signal is given. This is the case, if the valve spool does not reach the predetermined position. The most important reasons for this behaviour could be:? No or too low pilot presssure

? Blocking or defective valve mechanics by dirt ? No enable signal

? Input signal failure (only for option 4...20mA)The operating condition of the monitoring is indi-cated by a dual color LED within the valve electron-ics cover.

An explanation of the light indicator is printed on the placard on the cover.

Main (Central) Connector

The normal operating voltage levels for the valve electronic unit are available through the central connector.

In particular, the following individual possibilities are available:

6. Commissioning Ambient Conditions

The valve electronics unit has been designed to work reliably together with the hydraulic valve as a unit under normal industry conditions. It is pro-tected against environmental in?uences by its cast iron housing which also prevents the entry of for-eign particles and is sealed against the entry of water.The electronics are partly encapsulated and have a protective coating of varnish.

Even so, mechanical loading of the electronics box as well as its use outside of the following installation conditions is not allowed as permanent damage or a reduction in working life cannot be ruled out. It is advisable to install the unit directly by the machine, protected from extreme environmental in?uences.Input Circuitry

The differential input of the valve electronic unit ensures a freedom from input problems with the user’s set value signals.

Command Signal Control System

There are three basic variations on set value con-trol:

? Take the set value signal from a programmable logic control unit (PLC).

? Set value control through interface electronics.? Set value signals from preswitched controller.Connection Signal level representing

A djust the zero point until the actuator is in the neutral position or takes up the desired creep position.3. R eplace cover nut.The following command signal value results in the

electrical zero point of the valve:Enable Signal

The valve electronic unit uses an “enable” signal function in the range of 5...30V at pin C of the main connector (see chapter “Enable Signal Input“).

There are two different ways of controlling the en-able signal input:

? Using the 24V supply voltage through an enable switch provided by the user.? Feeding the enable signal from a control system

of the user with the reference (zero) point of the user's control connected to pin B of the central connector and the enable signal is connected to pin C.The enable signal must only be switched on to the valve electronics unit when the valve is to be used; all other times should be off.

Example: Start-up of a hydraulic control system As against the supply voltage, which will be switched on at the same time as the hydraulic system, the enable signal should preferably not be switched on until the hydraulic system has reached full pressure. This will prevent any system disturbance.Zero Point Equalising

The main valve spool takes up the spring-centred position if the power fails or the enable signal has not been given. Valves with overlap spools have a factory adjusted zero point. Valves with zero lap spools usually have mechanical centering. In this case there is a possibility of the operating condi-tions allowing the activated device e.g a cylinder, to creep in an uncontrolled direction; the valve electronics unit takes account of this possibility and allows the creeping movement in a prede?ned di-rection only.

Valves with overlapping type spools are factory-preset to null. In the case of valves with zero lap spools it is necessary for the user to adjust the electrical zero point in accordance with its require-ments. The adjusting can be done via a sel?ocking spindle trimmer in the valve electronic unit. The position of the trimmer is shown on the placard on the cover.

电液伺服阀的发展趋势与现状

电液伺服阀与比电液例阀的研究现状与发展趋势 摘要:电液比例阀是电液比例控制技术的核心元件,它按照输入电信号指令,连续成比例地控制液压系统的压力、流量或方向等参数。电液伺服阀是电液伺服控制系统中的关键元件。二者均在电液比例系统以及电液伺服系统中起到重要作用。本文中以电液比例换向阀和电液伺服阀为例详细介绍了其工作原理,并从性能、方展、前景等方面分别对两类阀进行了阐述,使我们对其有了更深刻的认识。 关键词:电液比例阀;电液比例换向阀;电液伺服阀;现状;趋势 1 引言 液压工业己成为全球性的工业,国际液压界一些著名公司如美国的派克汉尼汾公司(PARKER HANNIFIN)、德国的力士乐(REXROTH)和博世公司(BOSCH)等居世界领先地位,我国液压工业距国外还有一定的差距。 现代液控技术始于第一次世界大战后。今天,机电一体化的进程对液控技术提出了更多的需求,而计算机技术和控制理论的发展则为液压技术注入了新的动力。电液比例阀与电液伺服阀作为液压系统中的重要控制元件,分别代表了电液比例技术与电液伺服技术的发展情况。电液伺服阀与电液比例阀的出现使液压系统与现代化的电子技术结合的更加紧。 电液比例阀,是电液比例控制技术的核心和主要功率放大元件,代表了流体控制技术的发展方向[ 1 ] 。它以传统的工业用液压控制阀为基础,采用电- 机械转换装置,将电信号转换为位移信号,按输入电信号指令连续、成比例地控制液压系统的压力、流量或方向等参数。 电液伺服阀不仅能够实现微小电气信号向大功率液压信号(流量与压力)的转换,还可以根据输入电信号的大小,成比例地输出相应的流量和压力。因此,在电液伺服系统中,电液伺服阀将电气部分与液压部分连接起来,实现整个系统的控制策略和执行元件的动作。所以,电液伺服阀的性能,特别是其电液伺服阀的动特性和稳定性,直接影响到整个液压系统乃至机械设备的可靠性和寿命。电液伺服阀的发展史就是一部力图获得速度更快、精度更高、稳定性更好的创新史[ 2 ]。 2 发展历史 2.1电液伺服阀发展历史 最早使用液压伺服技术的机构也许已经湮灭在浩瀚的历史长河中。直到1750 年左右,用于控制给水系统和蒸汽锅炉水位的液位控制阀在英国出现。随着工业革命的发展,控制策略的不断改进, 进而影响到液压技术的发展。在二战前夕,由于空气动力学的应用要求一种能够实现机械信号与气体信号转换装置。在二战末期,伺服阀是采用滑阀阀芯在阀套中移动的结构。阀芯的运动是直流螺线管产生的电磁力与弹簧产生的压力共同作用的结果,因此,此时的伺服阀还仅仅是一种单级开环控制阀。二战结束后,电液伺服阀开发研制进入了迅速发展时期,很多结构设计进一步提高了电液伺服阀的性能。特别是1960年的电液伺服阀设计更多地显示出了现代伺服阀的特点。如:两级间形成了闭环反馈控制;力矩马达更轻移动距离更小;前置级对功率级的压差通常可达到50%以上;前置级无摩擦并且与工作油液相互独立;前置级的机械对称结构减小了温度、压力变化对零位的影响。

REXROTH伺服阀的原理

REXROTH伺服阀的原理 我司在德国、美国都有自己的公司,专业从事进口贸易行业,以下是我司的专业人士为大家所做的报告,具体请看下面描述: REXROTH伺服阀它在接受电气模拟信号后,相应输出调制的流量和压力。它既是电液转换元件,也是功率放大元件,它能够将小功率的微弱电气输入信号转换为大功率的液压能(流量和压力)输出。在电液伺服系统中,它将电气部分与液压部分连接起来,实现电液信号的转换与液压放大。电液伺服阀是电液伺服系统控制的核心。 REXROTH伺服阀的产品描述: 4WS(E)2EM 6-2X / ... 这种类型的阀门是电动的2级定向伺服阀,其端口模式符合ISO 4401-03-02-0-05。它们主要用于控制位置,力,压力或速度。 这些阀门由一个机电转换器(力矩电机)(1),一个液压放大器(原理:喷嘴挡板)(2)和一个套管(第二级)中的控制阀芯(3)组成。扭矩马达通过机械反馈。 扭矩电动机的线圈(4)处的电输入信号借助于作用在电枢(5)上的永磁体产生力,并且与扭矩管(6)连接产生扭矩。这使得通过螺栓连接到扭矩管(6)的挡板(7)从两个控制喷嘴(8)之间的中心位置移动,并且在控制阀芯的前侧产生压差。(3)。压差导致阀芯改变其位置,这导致压力端口连接到一个致动器端口,同时另一个致动器端口连接到回流端口。 控制阀芯通过弯曲弹簧(机械反馈)(9)连接到挡板或扭矩马达。改变阀芯的位置,直到弯曲弹簧上的反馈扭矩和扭矩马达的电磁扭矩平衡,并且喷嘴挡板系统处的压差变为零。 控制阀芯的行程以及因此伺服阀的流量与电输入信号成比例地控制。必须注意的是,流量取决于阀门压降。 外部控制电子装置(伺服放大器)用于操作阀门,放大模拟输入信号(指令值),以便通过输出信号,伺服阀以流量控制的形式启动。 REXROTH伺服阀的特征: 阀门控制位置,力,压力或速度 带机械反馈的2级伺服阀

REXROTH力士乐节流阀工作原理及使用

REXROTH力士乐节流阀工作原理及使用 REXROTH力士乐节流阀在工业中适用范围很广,广泛应用在工业中控制管道流体流量的简易控制阀,常常与一次仪表及其它阀门配合使用,进行管道流体流速的系统调节。其规格结构形式也分为许多种类型。 REXROTH力士乐节流阀的特征: 用于管道安装 与压力和粘度有关 在两个流动方向上节流 防腐蚀设计 下面简单说说:REXROTH力士乐节流阀工作原理及使用: REXROTH力士乐节流阀的内部核心部件,也就是阀杆阀芯组合成REXROTH力士乐节流阀的启闭件,其芯头大多为圆锥流线型,通过它改变管道截面积的大小,从而来达到调节管道流量和压力作用的。目前启闭件的结构有多种形式,用处不同,选用其结构形式就不同。 REXROTH力士乐节流阀还可以通过改变节流的长度来控制流体流量。如将REXROTH 力士乐节流阀和单向阀并联起来,则可组合成单向REXROTH力士乐节流阀使用;如将其与双向阀组合起来,则就能是双向REXROTH力士乐节流阀使用;REXROTH力士乐节流阀和溢流阀的配合也可组成节流调速系统。总之不同场合选用不同的组合形式。 REXROTH力士乐节流阀应用在定量泵液压系统中的系统调速时,即为进油路节流、回油路节流和旁路节流三种调速形式。因REXROTH力士乐节流阀没有流量负反馈功能,所以它常用在速度稳定性要求不高,或者在负载变化不大的场合。 其中当流体经过REXROTH力士乐节流阀时,REXROTH力士乐节流阀就能对流体起到

压力缓冲的作用,REXROTH力士乐节流阀会在一定程度上阻碍流体的运行,并减少其流体的冲击力。REXROTH力士乐节流阀口径大小不同,其内部结构性也有不同,用处也会各不相同的。但基本原理是相同的。 REXROTH力士乐节流阀在起到控制流体流量的作用时,一般来说是在REXROTH力士乐节流阀两端(管道前后)的压差一定时,其开口的大小直接影响着液体流量的变化。简单来说REXROTH力士乐节流阀起到的主要作用是截流调速的作用、负载阻力的作用和压力缓冲的作用。 注意事项 各型号的REXROTH力士乐节流阀的形式都会有不同之处,选用时要注意其连接形式和尺寸。 对REXROTH力士乐节流阀的应用,要实际情况实际分析。 威斯特(广东)传感器仪表有限公司(东莞市巴菲特自动化设备有限公司)是一家专业供应进口电磁阀、气缸、泵、传感器、继电器、开关、离合器、过滤器、滤芯、流量计、液位计、编码器、伺服阀等产品。 在德国美国都有自已公司,厂家一手货源,价格实惠,可提供报关单,直接出厂价拿货,批量采购还可直接拿到内部会员价格,详请致电。
