Working principle and application of diaphragm pump

Diaphragm pump is divided into pneumatic diaphragm pump and electric diaphragm pump. The whole working process of diaphragm pump refers to a process of suction and discharge. Driven by power, the piston is driven to and fro by the transmission mechanism (the stroke of the piston is changed by the regulating mechanism), and the diaphragm is pushed back and forth by hydraulic oil. When the piston moves backward, the diaphragm gradually concave, the volume of the pump chamber increases gradually, and the pressure decreases gradually. When the pressure is lower than the inlet pipe pressure, the inlet valve opens and the medium flows into the pump chamber. When the piston reaches the internal dead center, the medium fills the pump cavity and the inlet valve closes.

The suction process is completed and the extrusion process begins. When the piston moves forward, the diaphragm gradually bulges up, the volume of the pump chamber gradually decreases, the pressure increases gradually, the outlet valve opens, and the medium is gradually discharged from the pump chamber. When the piston reaches the external dead center, the outlet valve is closed due to gravity and spring force, and the discharge process is finished, and the pump starts a new suction process. In this way, the liquid is continuously inhaled and discharged to complete the purpose of conveying medium.

Since the pneumatic diaphragm pump has the above characteristics, the diaphragm pump has gradually invaded the market of other pumps in the world since its birth, and has been absolutely dominant. In other industries, such as environmental protection, wastewater treatment, construction, sewage discharge and refinement, it is expanding its market share, and has an irreplaceable position of other pumps.
