- product introduction:The static pressure of the system is used as the design initial pressure head in the expansion tank for the constant pressure make-up water unit equipment, and the pressure to ensure that the hot water in the system does not vaporize is used as the terminal pressure head in the expansion tank. During the initial operation, start the make-up pump to fill the water chamber of the system and the air pressure tank with water. After the system is filled with water, the excess water will be squeezed into the capsule. Because of the incompressibility of water, with the increase of water volume, the volume of water chamber is also expanding, and the pressure in the tank is also increasing. When the pressure reaches the design pressure, the make-up pump is shut down through the pressure controller. When the water in the system is heated and expanded to make the system pressure rise higher than the design pressure, the excess water is discharged to the make-up water tank for recycling through the safety valve. When the volume of water in the system is reduced due to leakage or temperature drop, and the system pressure is reduced, the water in the capsule is continuously pressed into the pipe network to make up for the pressure drop loss of the system. When the system pressure reaches the minimum pressure allowed by the design, the excess water is discharged through the pressure The controller makes the make-up water pump restart to make up water to the pipe network and the air pressure tank, and so on.
