离心泵在启动之前必须灌水,否则,叶轮仅在泵壳内空转,打不出水来。因此,泵壳及吸水管内应灌以所输液体,以使水泵充满。从最简单的“倒灌式”到复杂的自动灌水器或真空泵引水,至少有八种灌泵方式。的确,你可选用任何一种方式灌泵,但其是否经济,却不敢保证。究竟那种灌水方式最适于你所选择的设备?这就需要知道各种方式的不同 Centrifugal pumps must be filled with water before starting. Otherwise, the impeller will only idle in the pump casing and no water will come out. Therefore, the pump casing and the suction pipe should be filled with the liquid to fill the pump. From the simplest “inverted” type to complex automatic emitters or vacuum pumps, there are at least eight methods of irrigation. Indeed, you can choose to inject the pump in any way, but it is economic, but can not guarantee it. What kind of irrigation method is best suited to the equipment you choose? This requires you to know the different ways
