活塞式電磁閥故障現象和維修：

活塞式電磁閥故障二：開閥時流體不能通過

1、介質的壓力或者工作壓差不在活塞式電磁閥適應的工作范圍，處理辦法為調整介質壓力或者更換其他合適的活塞式電磁閥產品

2、活塞式電磁閥的閥芯周圍有雜質進入，需要對閥進行清洗，并安裝過濾網

3、閥前的過濾器過著閥孔被堵，需要進行清理

4、工作頻率太高或者使用壽命到期，更換新的電磁閥產品

活塞式電磁閥故障三：活塞式電磁閥關閉時介質不能切斷

1、介質的粘度和溫度不適合，更換新的電磁閥型號

2、活塞式電磁閥的彈簧變形或者損壞壽命到期等，需要更換新的彈簧

3、活塞式電磁閥的閥座有缺陷或者有異物，需要閥座面進行處理或清除異物

4、密封墊脫出缺陷或變形，需要更換新的密封墊

5、產品的使用壽命到期，需要更換新的活塞式電磁閥產品

活塞式電磁閥故障一：通電后不工作

1、活塞式電磁閥的電源接線接觸不良，需要接好電源線

2、電源電壓不在活塞式電磁閥允許的工作范圍內，需要調整電壓

3、由于線圈短路或者燒壞，處理辦法是更換電磁閥線圈
