換句話說：自吸泵是增壓泵，但增壓泵不一定是自吸泵。
In other words: self-priming pump is booster pump, but booster pump is not necessarily self-priming pump.
剖析
Analyse
辨別自吸泵和增壓泵之前，要對自吸泵和增壓泵的定義反復一下。
Before distinguishing between self-priming pump and booster pump, repeat the definition of self-priming pump and booster pump.
1自吸泵
1 self-priming pump
是指榜初次灌水后，以后再運用就無需再次灌水即可發(fā)起運轉(zhuǎn)，自吸泵能否自吸要看停機后葉輪能否浸入水中，自吸泵就是由于有共同的泵腔構(gòu)造而可以確保每次停機后葉輪都可以浸入水中才確保了其自吸;
The self-priming pump can start running without further irrigation after the first irrigation. Whether the self-priming pump can self-priming depends on whether the impeller can be immersed in the water after the shutdown. The self-priming pump can ensure that the impeller can be immersed in the water after each shutdown because of the common pump chamber structure.
2增壓泵
2 booster pump
是泛指能對管路的液體停止供應額定壓力的泵的統(tǒng)稱，并不指某一品種型的泵，增壓泵可以是管道泵、離心泵、污水泵、自吸泵、多級泵等類型泵。假設(shè)要讓非自吸式的增壓泵到達自吸作用(泵坐落水池上方)，可以在泵的吸入口加裝底閥即可。
It is a general term for pumps that stop supplying rated pressure to pipeline liquids. It does not refer to a particular type of pump. Booster pumps can be pipeline pumps, centrifugal pumps, sewage pumps, self-priming pumps, multi-stage pumps and other types of pumps. Assuming that the non-self-priming booster pump reaches the self-priming effect (the pump sits above the pool), the bottom valve can be installed at the suction port of the pump.
何時選擇自吸增壓泵比擬好?
When is it better to choose self-priming booster pump?
下列情況盡量選擇自吸式構(gòu)造的增壓泵以進步運用性或平安性：
In the following cases, the booster pump with self-priming structure is selected as far as possible to improve its usability or safety.
1、泵坐落水池(裝液體的設(shè)備)上方;
1. The pump is located above the water tank (equipment for loading liquid).
2、所抽液體有毒或有異味;
2. The extracted liquid is poisonous or odorous.
3、溫度較高(溫渡過高會影響自吸高度)。
3. Higher temperature (high temperature will affect the self-priming height).
增壓泵和自吸泵差別詳細在哪里?
Where is the difference between booster pump and self-priming pump in detail?
榜首、兩個泵都是可以增壓，一個是管道中心的水位高于泵體的(增壓泵)一個是管道中心的水位低于泵體的(自吸泵)好不要在自來水管線上直接裝自吸泵，有或許會把水表的玻璃吸碎的。
Top two pumps can be pressurized, 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 in the water pipeline, or it may suck the glass of the water meter.
第二、假設(shè)水沒有斷流情況可以使增壓泵，假設(shè)經(jīng)常斷流就要準備個容器了(水池、水罐等)，容器上可以裝排水管就還可以使增壓泵，不能裝排水管就只能裝自吸泵。
Secondly, if there is no water cut-off, the booster pump can be made. If there is no water cut-off, a container (pool, tank, etc.) will be prepared. If there is a drainage pipe on the container, the booster pump can also be installed. If there is no drainage pipe, the booster pump can only be installed with a self-priming pump.
