When the pressure reaches the design pressure, the pump is closed through the pressure controller. When the water in the system is heated and expanded so that the system pressure rises beyond the design pressure, the excess water is discharged to the water tank for recycling through the safety valve. When the water in the system shrinks due to leakage or temperature drop, and the system pressure decreases, the water in the capsule is continuously pressed into the pipe network to supplement the pressure drop loss of the system, and when the system pressure reaches the minimum pressure allowed by the design. Through the pressure controller to restart the water pump to the pipe network and pressure tank water, so repeat,
Working principle of constant pressure water refill device:
The static pressure of the system is used as the initial design pressure head in the expansion tank, and the pressure to ensure that the hot water in the system does not vaporize is used as the moving terminal pressure head in the expansion tank.
During the initial operation, the replenishment pump is first started to fill the water chamber in the system and the air pressure tank, and the excess water is squeezed into the capsule after the system is filled. Because of the incompressibility of water, with the continuous increase of water volume, the volume of the water chamber continues to expand and compress the gas chamber, and the pressure in the tank continues to rise.
When the pressure reaches the design pressure, the pump is closed through the pressure controller. When the water in the system is heated and expanded so that the system pressure rises beyond the design pressure, the excess water is discharged to the water tank for recycling through the safety valve. When the water in the system shrinks due to leakage or temperature drop, and the system pressure decreases, the water in the capsule is continuously pressed into the pipe network to supplement the pressure drop loss of the system, and when the system pressure reaches the minimum pressure allowed by the design. Through the pressure controller, the water refill pump is restarted to the pipe network and the pressure tank, and so on.
