Frequency conversion water supply system The variable frequency water supply system refers to the water supply mode in which the outlet pressure remains unchanged when the water consumption in the water supply pipe network changes.

The variable frequency water supply system refers to the water supply mode in which the outlet pressure remains unchanged when the water consumption in the water supply pipe network changes. The outlet pressure value of the water supply network is determined according to user needs. The traditional constant pressure water supply method is realized by water tower, high water level tank and pressure tank.

Frequency conversion water supply system


In recent years, with the increasing maturity of frequency conversion speed regulation technology, its remarkable energy-saving effect and reliable and stable control mode have been widely used in water supply systems. The variable frequency water supply system implements stepless speed regulation on the pump motor. It is the most advanced and reasonable energy-saving water supply system based on the water consumption and water pressure changes through the microcomputer detection and calculation, automatically changing the pump speed to keep the water pressure constant to meet the water requirements. Compared with traditional water towers, high water tanks, and pressure tanks, it has advantages in terms of investment, economics of operation, stability of system, reliability, and degree of automation:

1) High efficiency and energy saving. Compared with the traditional water supply method, the variable frequency constant pressure water supply can save 30%-60%.

2) Small footprint, low investment and high efficiency.

3) Flexible configuration, high degree of automation, complete functions, flexible and reliable.

4) The operation is reasonable. As the average speed decreases within one day, the average torque and wear on the shaft decreases, and the life of the pump will be greatly improved.

5) Due to the soft stop and soft start of the pump, and the water hammer effect can be eliminated (water hammer effect: the liquid kinetic energy increases sharply when starting and stopping directly, resulting in great impact on the pipe network, which is greatly damaged. force).

6) Easy to operate, saving time and effort.


The variable frequency water supply system takes the pipe network water pressure (or the user water flow rate) as the setting parameter, and automatically controls the rotation speed of the water pump motor by controlling the output frequency of the frequency converter through the microcomputer to realize the closed loop adjustment (PID) of the pipe network water pressure, so that the water supply system Automatically and constantly set at the set pressure value: when the water consumption increases, the frequency increases, the water pump speed increases, and the water supply volume increases accordingly; when the water consumption decreases, the frequency decreases, the water pump speed decreases, and the water supply volume decreases accordingly. This ensures the water supply efficiency requirements of users of water supply efficiency, and at the same time achieves the purpose of improving the quality of water supply and water supply efficiency, “how much water is used, how much water is supplied”; the equipment does not need to build high water tanks, water towers, water quality Secondary pollution is an ideal modern building water supply equipment.
