Shanghai Fengxian Equipment Vessel Factory was founded in 1982, and specializes in designing and
manufacturing all kinds of pressure vessels. We have a high profile
in the industry. And in 1998, we registered the brand of “Shen
Jiang”. Our pressure vessels are widely used in petroleum,
chemical, electronic, automotive, power generation, mining,
pharmaceutical and other industries. Look forward to the
cooperation with you in the increasingly powerful of our company.
2. pressure tank Introduction:
Pressure diaphragm tank including tank wall ,rubber diaphragm, air
inlet and outlet .
The material of tank : carbon steel and stainless steel .outside
tank with anti-corrosive painting
The material of diaphragm is Natural rubber .
The gas between the rubber and tank wall has been filled before
3. The characteristics of pressure tank
1.The inner rubber diaphragm structure ensure that the water is not
contacted with the wall of the tank, and the water quality is
ensured not to be polluted, and the tank body is not corroded
2. rubber diaphragm can relax more than 200 thousand times
3. Can eliminate the noise in the pipe network, effectively smooth
the pressure fluctuations in the water system, reduce the starting
and stopping frequency of the pump
4. rubber diaphragm with food grade safety can be used in the
drinking water system.
4. The principle of operation:
The equipment uses the compressibility of the gas in the tank to
adjust the quantity of water, when the external pressure of the
water into the rubber diaphragm. .gas sealed in the tank is
compressed, according to Boyle gas law, gas is compressed by the
volume change of pressure rise, stop the water until the swelling
pressure the gas and water tank. When the pressure reaches the same
gas pressure inside the tank is greater than the pressure of the
water swelling water loss reduced pressure, the gas expansion will
air inside the water up to the extrusion system, gas pressure and
water pressure until once again reach the agreement to stop the
High pressure water storage system, the release of water pressure
is low, and according to the change of pressure, start and stop to
realize voltage, control pump water, containment system expansion
effect. In the central heating system is mainly used to the bulk
absorption working medium increased due to changes in temperature
product; in water supply system is mainly used for a night the main
water pump water supply system to reduce electricity dormancy,
prolong the service life of the water pump.
5. The application of pressure tank :
which is widely used in the central air conditioner circulating
system. the Heating regulated water supply system, the Variable
frequency water supply system, fire protection water supply system
