隔膜泵原理和特点
Principle and characteristics of diaphragm pump
隔膜泵是用压缩空气作为动力源，是用膜片的往复变形来实现容积的变化来输送液体的输送装置。
Diaphragm pump is to use compressed air as a power source, the reciprocating deformation of the diaphragm to realize the change of volume to transport the liquid.
隔膜泵的10大特点：
The ten characteristics of diaphragm pump:
1）泵不会过热。其是有压缩空气为动力，在排气时是一个散热过程；
1) the pump won't overheat. It has the compressed air as the power, in the exhaust is a heat dissipation process;
2）不会产生火花。其是有压缩空气为动力，泵接地后防止静电及火花产生；
2) no spark is produced. It has the compressed air as the power, after the pump grounding to prevent electrostatic and spark generation;
3）可以输送含颗粒的介质。泵是容积式运行不易堵塞；
3) a medium containing particles can be conveyed. The pump is not easy to plug in the volume operation.
4）对输送介质的剪切力小。介质怎么进就怎么出；
4) the shear force of the conveying medium is small. How does the medium come out;
5）有自吸能力；
5) the ability of self priming;
6）可空运转；
6) can operate empty;
7）输送物料范围广；
7) a wide range of material delivery;
8）泵没有复杂的控制系统、操作简单；
8) the pump has no complicated control system and simple operation.
9）体积小、重量轻便于移动；
9) small volume, light weight in movement;
10）不用润滑、没有机械密封维修简单；
10) no lubrication, no mechanical seal maintenance simple;
