美国NUMATICS电磁阀运转中的问题及解决方案有哪些
美国NUMATICS电磁阀通常只有开关两种状态，阀芯只能处于两个极限位置，不能连续调节，(力图突破的新构思不少，但还都处于试验试用阶段)所以调节精度还受到定限制。电磁阀对介质洁净度有较高要求，含颗粒状的介质不能适用，如属杂质须滤去。另外，粘稠状介质不能适用，而且，特定的产品适用的介质粘度范围相对较窄。
1、美国NUMATICS电磁阀线圈烧坏，可拆下美国NUMATICS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，引起缘不好而漏磁，造成 线圈内电流过大而烧毁。 　　 　　对策：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。 　　 　　2、美国NUMATICS电磁阀接线头松动或线头脱落，美国NUMATICS电磁阀不得电，对策：可紧固线头。 　　 　　3、美国NUMATICS电磁阀卡住。安徽赛科环保科技供应的电磁阀的滑阀套与阀芯的配合间隙很小（小于0.008mm），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。 　　 　　对策：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。 　　 　　对策：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，若在个切换间隙内处理不完，可将切换系 统暂停，处理完毕

1, solenoid valve coil burned out, can remove the solenoid valve wiring, measured with a multimeter, if open, the solenoid valve coil burned. Moisture causes the coil, magnetic flux leakage caused by bad insulation, causing the coil current is too large to burn. Countermeasures: so to prevent flood water from entering the 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 "0" bit hit "1" bit manual button on the coil from the normal work, makes the valve open. 2, solenoid valve head loose or thread off wiring, electric solenoid valve shall be fastened thread:, countermeasures. 3, solenoid valve stuck. Slide valve sleeve and spool valve clearance Anhui SECCO environmental protection science and technology supply is very small (less than 0.008mm), are generally single assembly, when a mechanical impurities into or too little lubricant, it is easy to get stuck. Countermeasures: 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, clean with CCI4, making flexible movement in the valve spool sleeve. Demolition should pay attention to the assembly sequence and location of the external connection of each component, in order to re assembly and wiring is correct, also check whether the plug hole injector lubricator, lubricating oil is sufficient. 4, leakage. Lack of air pressure can cause leakage, making enforcement difficult to open and close the valve, the reason is the slide valve gasket damage or wear caused by several cavity channeling gas. Countermeasures: in dealing with the electromagnetic valve failure switching system, should select the appropriate time, such as the solenoid valve is energized when dealing with, if not processed in a gap switch, switching system can be suspended, disposed of.
