The self-priming pump includes a booster pump, but the booster pump does not necessarily belong to the self-priming pump. In other words: the self-priming pump is a booster pump, but the booster pump is not necessarily a self-priming pump. Before distinguishing between the self-priming pump and the booster pump, the definition of the self-priming pump and the booster pump must be repeated.

所谓自吸泵就是指一次灌水后，以后再使用就无需再次灌水即可启动运行，自吸泵是否自吸要看停机后叶轮是否浸入水中，自吸泵就是因为有独特的泵腔结构而可以保证每次停机后叶轮都可以浸入水中才保证了其自吸;增压泵是泛指能对管路的液体进行提供额外压力的泵的统称，并不指某一种类型的泵，增压泵可以是管道泵、离心泵、污水泵、自吸泵、多级泵等类型泵。如果要让非自吸式的增压泵达到自吸效果(泵位于水池上方)，可以在泵的吸入口加装底阀即可。

The so-called self suction pump refers to the first time after irrigation, then used again without irrigation can start running, self-priming pump is self-priming to stop after the impeller is immersed in water, self-priming pump is because of the unique structure of the pump cavity and can ensure that each stop after the impeller can be immersed in water to ensure its self suction; booster pump is refers to collectively liquid lines provide additional pressure pump, does not refer to a certain type of pump, booster pump is a centrifugal pump, pipeline pump, sewage pump, self-priming pump, multistage pump type pump. If you want the non self suction booster pump to achieve self absorption effect (pump located in the pool at the top), can be in the suction valve can be installed.

增压泵和自吸泵区别具体在哪里： 一、两个泵都是可以增压，一个是管道中间的水位高于泵体的，一个是管道中间的水位低于泵体的好不要在自来水管线上直接装自吸泵，有可能会把水表的玻璃吸碎的。 第二、如果水没有断流情况可以使增压泵，如果经常断流就要准备个容器了，容器上可以装排水管就还可以使增压泵，不能装排水管就只能装自吸泵。

The booster pump and a self-priming pump specific where: first, second pump can be pressurized, a water level is higher than the middle of the pipeline of the pump body, a water pipe is best not to the middle below the pump in the tap water pipeline directly self-priming pump, may put the broken glass ceiling water meter. Second, if the water is not stopped, you can make the booster pump, if often cut off, you have to prepare a container, the container can be installed drainage pipe, you can also make the booster pump, can not install the drain pipe, you can only install self-priming pump.
