Product Introduction:
Working principle: A diaphragm type pneumatic tank is an energy storage device composed of a steel shell and a rubber diaphragm inner tank. The rubber diaphragm completely separates the water chamber and the gas chamber. When water under pressure from the outside is filled into the inner tank of the diaphragm type pneumatic tank, the air inside the tank is compressed. According to the Boyle gas law, the volume of the compressed gas decreases, and the pressure increases to store energy. The compressed gas expands and can push the water inside the rubber diaphragm out of the tank.
Scope of adaptation:
Diaphragm type air pressure tanks are widely used in central air conditioning circulating water stabilization, steam water supply expansion systems, heating system circulating water replenishment and stabilization, fire water supply system replenishment and stabilization, variable frequency water supply and stabilization, boiler replenishment, pneumatic water supply and other occasions.
Equipment features:
•
The internal diaphragm structure of the tank ensures that water does not come into contact with the tank wall, so there is no rust inside the tank wall and no condensation outside, greatly extending its service life.
Rubber diaphragm can dilate up to 20 degrees
Over 10000 times, it can be used for a long time after inflation.
It can effectively smooth out pressure fluctuations in the water system and reduce the start stop frequency of the water pump.
•
The diaphragm is a food grade natural rubber diaphragm that can be used in drinking water systems.

Note: The small flow rate value in the water supply column refers to 6 pump starts per hour, and the maximum value in the water supply column refers to 10 pump starts per hour.
|
② For safe and reliable water supply, it is recommended to start the water pump at least 6 times per hour.Technical Performance Parameters Table of SQW Series Horizontal Diaphragm Pressure Tank
