高压电磁阀是自控系统中常用的阀门之一,它以价格低廉、使用简单、方便可靠(能直接接受PLC或DCS的开关量控制信号)而得到用户的一致青睐。当然,再好的东西也得使用的当才能发挥出它应有的功用,下面就把电磁阀在安装与使用维护方面需要注意的问题简单说明一下。
电磁阀安装注意事项:
1、先要检查电磁阀是否与选型参数一致,比如电源电压、介质压力、压差等,尤其是电源,如果搞错,就会烧坏线圈。电源电压应满足额定电压电压波动范围:交流 10%~-15%,直流 10%~-10%,平时线圈组件不宜拆开。
2、一般电磁阀的电磁线圈部件应竖直向上,竖直安装在水平于地面的管道,如果受空间限制或工况要求必须按侧立安装的,需在选型订货时提出。否则可能造成电磁阀不能正常工作。
3、接管之前要对管道进行冲洗,把管道中的金属粉末及密封材料残留物,锈垢等清除。要注意介质的洁净度,如果介质内混有尘垢,杂质等妨碍电磁阀的正常工作,管道中应装过滤器或滤网。
4、如果介质会起水锤现象,那么应该选用具防水锤功能的电磁阀或采取相应的防范措施。
5、电磁阀前后应加手动切断阀,同时应设旁路,便于电磁阀在故障时维护。
6、电磁阀一般是定向的,不可装反,通常在阀体上用→指出介质流动方向,安装时要依照→指示的方向安装。不过在真空管路或特殊情况下可以反装。
7、蒸汽用电磁阀入口侧应装有疏水阀,该处接管应倾斜。
8、尽量不要让电磁阀长时间处于通电状态,这样容易降低线圈使用寿命甚至烧坏线圈,就是说,常开、常闭电磁阀不可互换使用。
