电磁阀故障与排除
一、电磁阀通电后不工作
检查电源接线是否不良→重新接线和接插件的连接
检查电源电压是否在±工作范围-→调致正常位置范围
线圈是否脱焊→重新焊接
线圈短路→更换线圈
工作压差是否不合适→调整压差→或更换相称的电磁阀
流体温度过高→更换相称的电磁阀
有杂质使电磁阀的主阀芯和动铁芯卡死→进行清洗，如有密封损坏应更换密封并安装过滤器
液体粘度太大，频率太高和寿命已到→更换产品
二、电磁阀不能关闭
主阀芯或铁动芯的密封件已损坏→更换密封件
流体温度、粘度是否过高→更换对口的电磁阀
有杂质进入电磁阀产阀芯或动铁芯→进行清洗
弹簧寿命已到或变形→更换
节流孔平衡孔堵塞→及时清洗
工作频率太高或寿命已到→改选产品或更新产品
三、其它情况
内泄漏→检查密封件是否损坏，弹簧是否装配不良
外泄漏→连接处松动或密封件已坏→紧螺丝或更换密封件
通电时有噪声→头子上坚固件松动，拧紧。电压波动不在允许范围内，调整好电压。铁芯吸合面杂质或不平，及时清洗或更换。
