区分自吸泵和增压泵之前，要对自吸泵和增压泵的定义重复一下。

Before distinguishing self-priming pump and booster pump, the definition of self-priming pump and booster pump should be repeated.

1自吸泵

1 self priming pump

是指榜灌水后，以后再运用就无需再次灌水即可发动运转，自吸泵是否自吸要看停机后叶轮是否浸入水中，自吸泵就是由于有共同的泵腔结构而能够确保每次停机后叶轮都能够浸入水中才确保了其自吸;

It means that after filling water for the first time, the self-priming pump can be started without refilling water. Whether the self-priming pump is self-priming depends on whether the impeller is immersed in water after shutdown. The self-priming pump can ensure that the impeller can be immersed in water after each shutdown due to its common pump cavity structure;

2增压泵

2 booster pump

是泛指能对管路的液体进行供给额定压力的泵的统称，并不指某一种类型的泵，增压泵能够是管道泵、离心泵、污水泵、自吸泵、多级泵等类型泵。假如要让非自吸式的增压泵达到自吸作用(泵坐落水池上方)，能够在泵的吸入口加装底阀即可。

It generally refers to the general name of the pump that can supply the liquid in the pipeline with rated pressure, but does not refer to a certain type of pump. The booster pump can be pipeline pump, centrifugal pump, sewage pump, self-priming pump, multi-stage pump and other types of pumps. If you want to let the non self priming booster pump to achieve self-priming effect (the pump is located above the pool), the bottom valve can be installed at the suction port of the pump.

何时挑选自吸增压泵比较好?

When to choose self-priming booster pump is better?

下列状况尽量挑选自吸式结构的增压泵以进步运用性或安全性：

In the following conditions, the booster pump with self-priming structure shall be selected as far as possible to improve the usability or safety:

1、泵坐落水池(装液体的设备)上方;

1. The pump is located above the water tank (liquid equipment);

2、所抽液体有毒或有异味;

2. The extracted liquid is poisonous or has peculiar smell;

3、温度较高(温度过高会影响自吸高度)。

3. High temperature (too high temperature will affect the self suction height).

增压泵和自吸泵差异具体在哪里?

What is the difference between booster pump and self-priming pump?

榜首、两个泵都是能够增压，一个是管道的水位高于泵体的(增压泵)一个是管道的水位低于泵体的(自吸泵)更好不要在自来水管线上直接装自吸泵，有或许会把水表的玻璃吸碎的。

At the top of the list, two pumps are able to pressurize. One is that the water level in the center of the pipeline is higher than the pump body (booster pump), and the other is that the water level in the center of the pipeline is lower than the pump body (self-priming pump). It is better not to install the self-priming pump directly on the water pipeline, which may break the glass of the water meter.

第二、假如水没有断流状况能够使增压泵，假如经常断流就要预备个容器了(水池、水罐等)，容器上能够装排水管就还能够使增压泵，不能装排水管就只能装自吸泵。

Second, if the water does not cut off the situation can make booster pump, if often cut off the flow, it is necessary to prepare a container (pool, water tank, etc.), the container can be installed with drainage pipe can also make booster pump, can not install drainage pipe can only install self-priming pump.
