AWFB型无密封自控自吸泵安装使用说明书
(2)Electric Air-controlling valve
电动空气控制阀部分 Breakdown故障 Cause原因 1.There is no oil in the guide shaft, and the sealed piston is not in the right position. 导轴尖油卡死，密封活塞不到位。 2.There is no good contact between line and motor or the fuse is damaged. So, there is no electrical power and the piston is not active. 电缆与电机接线柱接触不良或保险丝损坏，电源不通，密封活塞不动作。 1.The two ends of the soft pipe connecting the controlling valve with the pump is loose or has a long time for use, or is corrosive, which cause the leakage. 控制阀和水泵连接的软管两端扎扣不紧或使用时间较长，扎扣腐蚀松动，造成漏气。 2.Because of the lining is old, and the piston is not tight. 密封垫片老化，活塞封闭不严。 Method排除方法 1.To add the sewer lubricating oil to the guide shaft. 在导轴上加缝纫机润滑油。 2.To check and connect the power. 检查接通电源。 The piston is not tight or not in good tight and the pump can’t self-priming. 活塞不封闭或封闭不严，水泵不吸液。 There is leakage in the soft connecting pipe and there is no vacuum in the pump. So, the pump is not self-priming. 连接软管漏气，水泵不能形成真空，不吸液。 1.To check handle or change the parts to assure there is no leakage. 检查、处理或更换扎扣件，保证牢固、可靠、不漏气。 2.Change the lining. 更换密封垫片。
