The working principle of Pressure tank: Pressure tank is a energy storage device consists of a steel shell, rubber bladder. The rubber bladder completely separated the water from the gas chamber. The pressure tank absorb the expansion water when it used for heating and air conditioning system, which have a closed water system. Also a pressure tank could balance the water and pressure of water system. When the water system cooling, the nitrogen inside the vessel will push the bladder to the bottom of the tank, water does not enter into the pressure tank. When the water temperature increasing, the pressure increasing, water pressure is higher than the nitrogen pressure, then the thermal expansion the water into the pressure tank.
Adaptation of Pressure tank: Pressure tank is widely used in central air-conditioning, boilers, fire, water treatment, water heater and so on. Pressure tank is also used in the circulating water of central air conditioner pressure steady, water supply expansion system, heating system circulating water pressure, fire water supply system water pressure steady, frequency conversion water supply pressure steady, boiler, air pressure water supply and other occasions.
Pressure tank function: Pressure tank in closed water cycle system plays a balancing role of water and pressure, it can avoid the safety valve to start frequently. Also can avoid the automatic water valve replenishment frequently. In addition, in the water system, expansion tank can also reduce the pump start frequently. It can be used to absorb water shock which caused by starting and closing of valve and pump in water system. It also can be used few water supply system, makes the main pump dormancy to reduce electricity consumption at night, prolong the life of the pump.
Pressure tank characteristics: Internal bladder structure ensures that the water does not touch with the tank wall, so the walls of the pressure tank internal no rust and the pressure tank without dewing phenomenon, this prolong the life of tank greatly. Compared with traditional water container, expansion tank in refrigeration and HVAC system has the advantages of convenient installation ( not installed in the highest point ) takes up little space, no two times pollution, long life and so on.
