金华升降机使用的电磁阀出现故障将直接影响切换阀和调节阀的工作，那么当电磁阀出现故障时应如何进行排查呢？
1、金华升降机使用的电磁阀线圈烧坏，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；
Solenoid valve coil used to burn, remove the solenoid valve wiring, measured with a multimeter, if open the solenoid valve coil burned out;
2、金华升降机电磁阀接线头松动或线头脱落，电磁阀不得电，可紧固线头。
Solenoid valve terminals loose or thread off, solenoid valve shall be fastened thread.
3、金华升降机使用电磁阀线圈受潮，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。
Use solenoid valve coil moisture, magnetic flux leakage caused by bad insulation, causing the coil current is too large to burn, so to prevent rainwater from entering the solenoid valve. In addition, excellent spring, the reaction force is too large, too small coil turns, the suction can not make the coil burnt.
4、电磁阀卡住，电磁阀的滑阀套与阀芯的配合间隙很小，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。
Solenoid valve stuck, with the gap of the solenoid valve spool valve sleeve and spool is very small, usually one-piece assembly, when a mechanical impurities into or too little lubricant, it is easy to get stuck. Treatment can hold into the wire from the head of the hole to make it bounce. The fundamental solution is to remove the solenoid valve, remove the spool and spool cover, with CCI4 cleaning kit allows flexible movement of the valve spool. Demolition should pay attention to the external wiring assembly sequence and position of each component in order to re-assembly andwiring is correct, also check whether the plug hole injector lubricator, lubricant is adequate.
5、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。
Leak, the leak can cause insufficient air pressure, making difficult to force the valve opening and closing, because the slide valve gasket damage or wear caused by several cavity channeling gas.
