Electric Single Diaphragm Pump, Electric Diaphragm Pump For Sale, pVDF, SS304, 316
Ⅰ. General description
For the transfer of trash, water, sludge, fuel, slurry, sewage, wastewater, chemical, acid, etc, our plastic electric diaphragm pumps are an ideal transfer pump. It is a positive displacement pump which utilises two flexible diaphragms that reciprocate back and forth creating a temporary chamber, which both draws in and expels fluid through the pump. It delivers a hermetic seal between the drive mechanism and the compression chamber, allowing the pump to transfer, compress, and evacuate the medium without a lubricant. An elastomeric diaphragm (PTFE, or rubber), can be used as a versatile dynamic seal that removes many of the limitations found with other sealing methods.
How to select an electric diaphragm pump:
1st step: the liquid or fluid type to be checked for the chemical compatibility characteristics
2nd step: max flow range and pressure head
3rd step: max self priming height if it's needed
4th step: max particle diameter if it has particle
Ⅱ. Work Principle
The two symmetrical working chamber, each is equipped with a piece of elastic diaphragm, which is connected by a connecting rod that square groove is on the above. With the key, the motor shafter is connected to a piece of eccentric shaft connected with the bearing, which is working with the above square groove. Connecting rod can be working, when the motor rotates.
When connecting rod shaft to the left movement, the left chamber being in compression state, the liquid was squeezed out of the chamber, at the same time the right side of the chamber is on expansion, so the external liquid can be inhaled into the chamber in the body; After connecting rod movement to the right, the right chamber in compression state, the liquid is compressed to outside, at the same time the left chamber on the expansion can the external fluid into the
chamber in the body, thus realize the motor drives the diaphragm work back and forth, the medium's transfer function.
