水泵底阀常见的故障部位,其处理方法已取得了不少经验,但对于活动阀瓣式底阀的故障处理,长期以来一直尚未得到解决。活动阀瓣式底阀在工作中的主要故障,是经常灌不满引水,或抽不出水来(引水为自灌)。如果一旦发生了故障,夏天要潜入水中检修,冬天则要拆下拿到地面上检修。它有一个与其它底阀不相同的怪现象,当检修时完好无损,阀瓣上下活动自如,将它安装到水中后工作不了多久,又时而出毛病。在长期的工作实践中,对5个单位5台
The common fault location of the water pump bottom valve has acquired a lot of experience in its treatment method, but the failure treatment of the active valve bottom valve has not been solved for a long time. The main fault of the active valve-type bottom valve in the work is that the water is always filled with water or the water is not drawn (draining is self-irrigation). If there is a failure, it is necessary to dive into the water for maintenance in the summer and remove it in the winter for maintenance. It has a strange phenomenon that is not the same as other bottom valves. When it is overhauled and intact, the valve flap moves freely up and down. After installing it into the water, it will not work for a long time, and sometimes it will go wrong. In long-term work practice, 5 units for 5 units
