Mini Diaphragm pump working principle

Mini Diaphragm Pump working principle

A mini diaphragm pump is a commonly used fluid transfer device that can be used to transfer liquids from a container to transfer to another container without adding or expending energy. It works by fluid transfer is achieved by the reciprocating motion of an elastic diaphragm.


The structure of the diaphragm pump is composed of the pump body, the driving device, the diaphragm and the sealing ring, among which the diaphragm is the core part of the pump body, which is made of an elastic membrane, is housed in a ring-shaped sealing ring.When the driving device is working, the diaphragm will vibrate, which will generate a driving force on the fluid and make the flow body from one container to another.

The working principle of the Mini Water Pump can also be divided into two stages: the suction stage and the discharge stage. pumping in the suction stage, the diaphragm vibrates to generate a vacuum, so that the fluid in the container is sucked into the diaphragm pump;In the out stage, the diaphragm vibrates in the opposite direction, and the fluid is discharged from the pump body and finally flows into the other pump body container.


The advantages of the diaphragm pump are its simple structure, low price, stable operation, low energy consumption, and no pollution, can withstand high pressure, adjustable flow, adjustable speed, etc. But it also has some shortcomings
Points, such as being easily affected by ambient temperature changes, high friction coefficient, temperature influence

Larger range, shorter lifespan, etc.


The working principle of the Mini Liquid Pump is to realize the flow through the reciprocating oscillation of an elastic diaphragm body transfer, its advantages are simple structure, low price, stable operation, low energy consumption,
No pollution, etc., but it also has some disadvantages, such as being easily affected by changes in ambient temperature
Noisy, high friction coefficient, large range of temperature influence, and short service life.
