What is an air-operated diaphragm pump?
The air-operated diaphragm pump is a new type of conveying machinery that uses compressed air as the power source. Its working principle is to continuously fill or discharge the compressed air into or out of the diaphragm chamber by pneumatically controlling the opening and closing of the valve, so that the diaphragm is reciprocatingly deformed, so as to realize the suction and discharge of the pump. The air-operated diaphragm pump has the following features:
No moving parts, no mechanical friction and wear, no regular maintenance, long service life.
There are no valves and mechanical seals, so there are no problems such as clogging and wear.
It can convey a wide range of corrosive liquids, liquids with particles, highly viscous liquids, and flammable, explosive, and highly toxic liquids.
The flow rate and pressure can be controlled by adjusting the pressure of the compressed air, which is simple and convenient to operate.
It can be self-priming, that is, it does not need to inject water or vacuum when starting, and the suction port of the pump can be directly placed below the liquid level to achieve self-priming.
The air-operated diaphragm pump has a beautiful appearance, compact structure, can adapt to various working conditions, can be customized according to the needs of customers, and has a wide range of uses.
The air-operated diaphragm pump is an efficient, reliable, energy-saving and environmentally friendly conveying equipment, which has been widely used in industry, water treatment, petroleum, electric power and other fields.
What are the principles of air-operated diaphragm pumps?
The working principle of the air-operated diaphragm pump mainly includes the following steps:
Compressed air enters the pump body and is fed into the pump through the intake valve.
The air pressure pushes the diaphragm to move, and when the air enters the pump body, the valve switches so that the air enters the back chamber of one of the diaphragms and the air in the front chamber of the diaphragm is discharged at the same time. Due to the pressure difference between the front and rear chambers of the diaphragm, the air pressure in the rear chamber forces the diaphragm forward, thus drawing the liquid inside the pump.
When the diaphragm is moved forward, the volume between the rear chamber and the pump body changes, creating a certain vacuum degree that sucks the liquid into the pump.
After the liquid is inhaled, the liquid is continuously sucked in and discharged with the reciprocating motion of the diaphragm, so as to achieve the function of continuous transportation.
A muffler is installed at the outlet of the air-operated diaphragm pump, which can eliminate the noise generated by the operation of the pump.
The working principle of the pneumatic diaphragm pump is to push the diaphragm reciprocating motion through air pressure, so that the vacuum degree is generated in the pump, and the liquid is sucked into the pump, so as to realize the transfer of liquid.
