摘要
文章分析了多级自吸泵的工作过程,研究设计了一种能实现自动排气,轴封润滑水末级叶轮出水处低压供水,正常工作后能自动关闭排气口,同时轴封润滑水切换到首级叶轮出水处保持低压供水功能的控制器。
The paper analysed the working process of the multistage self-priming gned an integrated controller which could supply low pressure water from last exhausting and automatic closing after working, also shaft seal lubrication water pump,researched and desistage impeller when auto-switching to the first stage and supply low pressure water continuously.
