Overview of constant pressure water supply device
The device adopts the system static pressure as the initial pressure head of the expansion tank, and the pressure of the hot water in the system is guaranteed to operate in the expansion tank. The initial movement of the water supply pump to the system and the pressure tank filled with water, the system is filled with excess water is squeezed into the capsule. Because of the water can not be compressed, with the increasing amount of water, the volume of the water chamber is also expanding and compressed air chamber, the pressure inside the tank is also rising. When the pressure reaches the design pressure, the pressure controller makes the water pump shut down, when the system is in thermal expansion of water makes the system pressure exceeds the design pressure, excess water through the exhaust valve to fill the tank when the recycled water in the system due to leakage or drop in temperature and volume reduction, the reduction of system pressure, pressure drop the loss of water in the capsules being pressed into the network of the system, when the minimum pressure system pressure to the design condition, the water pump water pipe network to restart the pressure tank and the pressure controller, so the cycle.
Main features of constant pressure water supply unit
1, an inflation can be maintained for a long time.
2, the tank is a closed device, gas water does not contact, can ensure that the water quality is not polluted outside, and no corrosion tank.
3, covers an area of less, investment, installation, operation, management and maintenance is simple.
4, eliminating the building of high water tank, saving investment structure.
5, the water pipe plays a buffer role, which can eliminate the impact of water hammer on the pipe network.
6, automatic control, reliable operation.

For example: DY-1.0-22 said, 1000 tank diameter, pump head 22m
▲Pump models are generally designed according to the actual needs of designers, but also by the company according to the design conditions of choice
▲The equipment _ general configuration for a jar of two pumps, may also need to configure a tank in a pump, a pump tank three, two tank two pump etc.
The factory is equipped with a control cabinet, pressure controller, water pump outlet valve, base, pipe group, exhaust valve, etc.
