自吸泵与增压泵有什么样的区别?

发布时间:2019-07-10 17:12:46   发布人:http://www.sdjingtuo.com
换句话说:自吸泵是增压泵,但增压泵不一定是自吸泵。
In other words: self-priming pump is booster pump, but booster pump is not necessarily self-priming pump.
剖析
Analyse
辨别自吸泵和增压泵之前,要对自吸泵和增压泵的定义反复一下。
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,以后再运用就无需再次灌水即可发起运转,自吸泵能否自吸要看停机后叶轮能否浸入水中,自吸泵就是由于有共同的泵腔构造而可以确保每次停机后叶轮都可以浸入水中才确保了其自吸;
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增压泵
2 booster pump
是泛指能对管路的液体停止供应额定压力的泵的统称,并不指某一品种型的泵,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。假设要让非自吸式的增压泵到达自吸作用(泵坐落水池上方),可以在泵的吸入口加装底阀即可。
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.
何时选择自吸增压泵比拟好?
When is it better to choose self-priming booster pump?
气体增压泵
下列情况尽量选择自吸式构造的增压泵以进步运用性或平安性:
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(装液体的设备)上方;
1. The pump is located above the water tank (equipment for loading liquid).
2、所抽液体有毒或有异味;
2. The extracted liquid is poisonous or odorous.
3、温度较高(温渡过高会影响自吸高度)。
3. Higher temperature (high temperature will affect the self-priming height).
增压泵和自吸泵差别详细在哪里?
Where is the difference between booster pump and self-priming pump in detail?
榜首、两个泵都是可以增压,一个是管道中心的水位高于泵体的(增压泵)一个是管道中心的水位低于泵体的(自吸泵)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。
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、假设水没有断流情况可以使增压泵,假设经常断流就要准备个容器了(水池、水罐等),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。
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.
