Diaphragm Pressure Tank Product Overview

The diaphragm type pressure tank adopts standard or non-standard design, standardized welding technology, and has air supply and deflation devices. It is divided into two types: diaphragm type and normal type. The surface is coated with advanced spray technology and has high corrosion resistance. Widely used in pneumatic water supply equipment and pressurized regulated water supply equipment. The diaphragm type pressure tank is an energy storage device composed of a steel outer casing and a rubber diaphragm inner tank. The rubber diaphragm completely separates the water chamber and the air chamber, and is sealed when the pressurized water is filled into the inner tank of the diaphragm type pressure tank. The air in the tank is compressed. According to Boyle's law of gas, the volume of the gas is compressed, the volume is reduced, the pressure is increased to store energy, and the expansion of the compressed gas can push the water in the rubber diaphragm out of the tank.
Diaphragm pressure tank product features
1. Wide range of withstand voltage;
2, strong corrosion resistance;
3. Easy to use and maintain;
4. Safe and reliable operation.
5. The internal diaphragm structure of the tank ensures that the water does not come into contact with the tank wall, so there is no rust inside the tank wall, no condensation on the outside, and the service life is greatly prolonged.
6, the rubber diaphragm can relax more than 200,000 times, can be used for a long time after inflation.
7, can effectively smooth the pressure fluctuations in the water system, reducing the start and stop frequency of the pump.
8. The diaphragm is a food grade natural rubber diaphragm that can be used in drinking water systems.

Diaphragm pressure tank adaptation range
Diaphragm pressure tanks are widely used in central air conditioning circulating water regulators, steamed water supply expansion systems, heating system circulating water hydration regulators, fire water supply system hydration regulators, frequency conversion water supply regulators, boiler hydration, pneumatic water supply and other occasions. The high working pressure of the diaphragm type pressure tank is 0.6mpa, 1.0mpa, 1.6 mpa, the fire water storage volume is more than 150L, 300L, 450L, and the regulated water volume is more than 50L. When used in the fire hydrant system, the water gun per flow is 2.5L. /S, 5L/S, the length of the water column is 7M, 10M, 13M; for the automatic water spray system, the flow rate of each nozzle is 1.0L/S, and the nozzle pressure is 0.1MPA. The equipment can keep the fire pressure of the fire water supply pipeline system at all times, and always use the pressure water tank to store 30 seconds of fire water; the equipment uses the operating pressure set by the pressure water tank to control the pump operating conditions and increase Voltage regulation function.
