Pressure tank pressure tank works mainly by the valve cover, inflatable mouth, air bags, steel tanks, flanges composition, when it is connected to the water system, the main function as a storage device, and when the water pressure is greater than steel expansion tank when the tank at a nitrogen pressure of the air bag between the system water will squeeze into the expansion tank airbag system under the action of pressure, so that one will be compressed nitrogen gas tank between the balloon, its volume decreases , the pressure increases; the second is to increase the entire water system accommodating space, the system pressure is reduced until the system water pressure and body to reach a new equilibrium between the nitrogen pressure in the airbag did not stop the water. When the system water pressure is less than the gas pressure in the expansion tank, water balloon will be in the tank on the balloon between nitrogen pressure extrusion, fill back to the system, the system volume decreases water pressure increases, the bladder tank between nitrogen volume increases pressure drops, until both reach a new equilibrium, the water stops flowing from the airbag squeeze back into the system, the pressure tank to play the role of regulating the system pressure fluctuation. Structure is as follows: tank between the airbag is factory pre-charge of nitrogen tank outside the paint layer, inlet and outlet connected directly to the system with a tee or metal hose, exhaust valve interface can be promptly removed from the system and balloon The water overflow air valve can also be directly related to the death in order to avoid overflow of water from the top, the dust cap is below inflation / deflation port, add nitrogen or release the portion of the gas. How to choose the pressure tank water supply equipment water supply equipment currently on the structure and control a variety of ways, water supply equipment in the structure more use of "pump group + inverter cabinet" form. In general, and the production of different water rationing supply, domestic water consumption curve large and obvious time characteristic, therefore, domestic water supply equipment should have "more water, more power; less water, less power consumption," the energy-saving features. How to choose the right pressure tank it? Pressure tank pump can go to sleep is a prerequisite for the use of water compressibility minimal nature, with the force of water stored in the tank, the gas is compressed pressure rises, when the external force disappears compressed gas expansion water may be excluded. Since water is much less than the gas compression ratio, when the small flow pipe leaks can cause a significant decrease in pressure, make frequent pump starts. As frequency pump water directly to users, it must be equipped with pressure tank, relieve frequent pump starts. Pressure tank models Model Volume (L)? Diameter (mm)?
