陈籍水泵在启动以前，泵壳和吸水管内必须先布满水，这是因为有空气存在的情况下，泵吸人口真空无法形成和保持。

B.water-filled Pump start before the pump casing and suction pipe must be full of water that is because of the presence of air vacuum pumping the population can not be formed and maintained .

若在吸水管上加装负压吸水罐，可在底阀泄漏情况下，使吸水管内水位不下降，启动泵时可省去灌泵程序。

If installs negative-pressure container on the syphon , in the condition of bottom valve leaking enables the water level in the syphon not fall , when start the pump , can leave out the procedure of pouring the pump body with water .

设计不良的泵站进水建筑物，在不带泵运行的情况下，也会引起水泵进口水流预旋和吸水管内涡流，改变水泵的进水条件，恶化水泵的能量特性和汽蚀特性。

Incorrect designed intake structure of a pumping station may result in pre swirl in the flow entering the pump and swirl in suction pipe even under no pump operation , which shall change flow condition , and affect adversely both pump performance and cavitation characteristics .
