Technical characteristics:

 

Mine pneumatic diaphragm pump with currents reciprocating the reversing va e core, make the compressed air around alternately into the cavity, to push the diaphragm is concave and convex reciprocating movement and make the working chamber to produce differential pressure, reach the purpose of absorbing water and drainage. Small volume, light weight, no roots, can be used as portable pump, without lubrication, the main va e of air without special requirements, can be self-priming is up and running.

 

working principle:

 

Mine pneumatic diaphragm pump using the air chamber pressure difference of alternating suction fluid pressure in the liquid chamber and liquid pressure, control va es, liquid can be sure of positive flow. After aeration, the pump starts running, and a continuous work to ensure that the required pressure remains constant, the pump will increase and maintain the pipeline pressure, and the maximum duct pressure (or distributing va e closed), will cease to work, and when necessary, restore pumping.
