电磁阀在我们的生产中应用十分广泛，我们在对生产的维护中一定遇见过不少有关电磁阀的问题，也处理过各种各样的故障，大家也一定积累了不少有关电磁阀故障处理的经验，而我在维护中处理电磁阀故障相对别的仪控故障相对较少，现在我就这个问题一起和大家讨论，渴望从大家那里学习更多的经验，共同提高。 我们先对电磁阀有个初步的认识，电磁阀是由电磁线圈和磁芯组成，是包含一个或几个孔的阀体。当线圈通电或断电时，磁芯的运转将导致流体通过阀体或被切断，以达到改变流体方向的目的。电磁阀的电磁部件由固定铁芯、动铁芯、线圈等部件组成；阀体部分由滑阀芯、滑阀套、弹簧底座等组成。电磁线圈被直接安装在阀体上，阀体被封闭在密封管中，构成一个简洁、紧凑的组合。我们在生产中常用的电磁阀有二位三通、二位四通、二位五通等。这里先说说二位的含义：对于电磁阀来说就是带电和失电，对于所控制的阀门来说就是开和关。 我们制氧机仪控系统中，二位三通电磁阀用的最多，它在生产中可用来接通或切断气源，从而对气动控制膜头气路进行切换。 它由阀体、阀罩、电磁组件、弹簧及密封结构等部件组成，动铁芯底部的密封块借助弹簧的压力将阀体进气口关闭。通电后，电磁铁吸合，动铁芯上部带弹簧的密封块把排气口关闭，气流从进气口进入膜头，起到控制作用。当失电时，电磁力消失，动铁芯在弹簧力作用下离开固定铁芯，向下移动，将排气口打开，堵住进气口，膜头气流经排气口排出，膜片恢复原来位置。在我们的制氧设备中，在透平膨胀机进口薄膜调节阀的紧急切断等处有应用. 四通电磁阀在我们的生产中应用也很多，其工作原理如下： 当有电流通过线圈时，产生励磁作用，固定铁芯吸合动铁芯，动铁芯带动滑阀芯并压缩弹簧，改变了滑阀芯的位置，从而改变了流体的方向。当线圈失电时，依*弹簧的弹力推动滑阀芯，顶回动铁芯，使流体按原来的方向流动。在我们制氧生产中，分子筛切换系统强制阀的开关就是通过二位四通电磁阀来控制的，气流分别供至强制阀的活塞两端。从而来控制强制阀的启闭。电磁阀的故障将直接影响到切换阀和调节阀的动作，常见的故障有电磁阀不动作，应从以下几方面排查： （1）电磁阀接线头松动或线头脱落，电磁阀不得电，可紧固线头。 （2）电磁阀线圈烧坏，可拆下电磁阀的接线，用万用表测量，如果开路，则电磁阀线圈烧坏。原因有线圈受潮，引起绝缘不好而漏磁，造成线圈内电流过大而烧毁，因此要防止雨水进入电磁阀。此外，弹簧过硬，反作用力过大，线圈匝数太少，吸力不够也可使得线圈烧毁。紧急处理时，可将线圈上的手动按钮由正常工作时的“0”位打到“1”位，使得阀打开。 （3）电磁阀卡住。电磁阀的滑阀套与阀芯的配合间隙很小（小于0.008mm），一般都是单件装配，当有机械杂质带入或润滑油太少时，很容易卡住。处理方法可用钢丝从头部小孔捅入，使其弹回。根本的解决方法是要将电磁阀拆下，取出阀芯及阀芯套，用CCI4清洗，使得阀芯在阀套内动作灵活。 拆卸时应注意各部件的装配顺序及外部接线位置，以便重新装配及接线正确，还要检查油雾器喷油孔是否堵塞，润滑油是否足够。 （4）漏气。漏气会造成空气压力不足，使得强制阀的启闭困难，原因是密封垫片损坏或滑阀磨损而造成几个空腔窜气。 在处理切换系统的电磁阀故障时，应选择适当的时机，等该电磁阀处于失电时进行处理，若在一个切换间隙内处理不完，可将切换系统暂停，从容处理。

Solenoid valve in the production of our wide range of applications, we are definitely on the maintenance of production had met many of the problems related to electromagnetic valve, also dealt with a variety of failures, we must also accumulated a lot of the solenoid valve failure treatment experience, and I dealt with in the maintenance of valve failure as compared to other relatively small instrumentation failure, and now I discuss this issue together and we are eager to learn more from the experience of all there together. We first solenoid valve has a preliminary understanding, the electromagnetic valve is formed by the electromagnetic coil and the core is the inclusion of one or a few holes in the body. When the coil power, or power, the core of the operation will result in fluid through the valve body or cut off, in order to achieve the purpose of changing the flow direction. Electromagnetic valve parts by the fixed iron core, moving core, coil and other components; in part by the sliding spool valve, slide valve sleeve, the spring base and other components. Electromagnetic coil is installed directly on the body, the body is enclosed in sealed tube is a simple and compact structure. We used in the production of solenoid valves have two three links, two-way, two five-pass and so on. Here first to give two meanings: it is charged for the solenoid valve and the loss of electricity, for it is under the control of the valve on and off. We Oxygen instrument control system, the two most widely used way magnet valve, which can be used in production to connect or disconnect the gas source, and thus the first pneumatic membrane pneumatic control switch. It consists of valve body, valve cover, electromagnetic components, springs and seal structure component parts, moving core at the bottom of the pressure sealing block with the spring will close the inlet valve. Power, the magnet pull, moving core top with spring seal block the vents closed, air intake into the film from the first, controlling play. When the loss of electricity, the electromagnetic force disappeared, moving core force in the spring to leave the fixed iron core, moving down, the exhaust port to open, blocked air intake, the membrane after the first air exhaust outlet, patch to restore its original position. In our oxygen equipment, imported films in the turbo expander emergency cut off valve, etc. are applied. Four-way solenoid valve in our production applications are many, it works as follows: When the current through the coil, the produces excitation effect, pull the fixed iron core moving core, moving core and the compression spring pulls the sliding spool, changing the position of the sliding spool, thus changing the flow direction. When the circuit power off, the * spring will push the sliding spool back to moving core, so that the direction of fluid flow according to the original. In our oxygen production, molecular switching system, switching valve is forced through two four-way solenoid valve to control, gas flow is provided to force the valve piston ends. To force the valve to control the opening and closing. Solenoid valve failure will directly affect the switching valve and valve action, a common fault with electromagnetic valve does not, troubleshoot the following aspects should be: (1) solenoid valve head loose or thread off wiring, electric solenoid valve shall be fastened thread. (2) solenoid valve coil burned out, can remove the solenoid valve wiring, measured with a multimeter, if open, the solenoid valve coil burned out. Moisture causes the coil, magnetic flux leakage caused by bad insulation, causing the coil current is too large to burn within, so to prevent flood water from entering solenoid valve. In addition, excellent spring, reaction force is too large, too few coil turns, the suction can not make the coil burnt. Emergency treatment, can be manual coil on the button from the normal work of the "0" bit hit "1" bit, makes valves open. (3) solenoid valve stuck. Electromagnetic valve slide valve sleeve and spool with a small gap (less than 0.008mm), are generally single assembly, when a mechanical impurities into or too little lubricant, it is easy to get stuck. Treatment can hold into the wire hole from the head to make it bounce. The fundamental solution is to remove the valve, remove the spool and spool cover, with CCI4 cleaning, making spool in the valve kit flexible movement. Demolition should pay attention to all parts of the assembly sequence and position of the external connection for re-assembly and wiring is correct, also check whether the plug hole injector lubricator, lubricating oil is sufficient. (4) leak. Lack of air pressure can cause leakage, making mandatory the valve opening and closing difficult, because the gasket damage or wear caused by sliding valve cavity channeling some air. Switching system in dealing with the electromagnetic valve failure, should select the appropriate time, such as the solenoid valve in the power off processing, if a switch gap within the never-ending, can be switched system suspended stride.
