Overview of fully automatic intelligent constant pressure water replenishment device

The constant pressure expansion water replenishment device is an equipment adopted by our company based on the actual situation in China to achieve energy-saving water replenishment for centralized heating, central air conditioning water systems, and industrial circulating water systems. It is an electromechanical integrated water supply device that applies constant pressure tanks, AC variable frequency speed regulation technology, and microcomputer control technology to the automatic control of water pumps, and is combined with water pump units. It is a water supply equipment that can replace high-level water tanks and towers, with relatively stable pressure, avoiding frequent starting of water pumps, energy saving, and low noise. Based on the instantaneous changes in pressure and flow parameters in the water supply network, this equipment automatically uses a constant pressure tank to adjust, change the number and speed of water pumps, and achieve closed-loop regulation of constant pressure variable water supply (replenishment), so that the system is in an energy-saving operating state.

Working principle of fully automatic intelligent constant pressure water replenishment device

At present, there are three series that can be applied to three common types of constant pressure water replenishment methods, providing more choices for designers and users:

A-series: Variable frequency constant pressure water replenishment method, occupying a very small area.

B series: Constant pressure water replenishment method for expansion tanks, selecting the volume of the expansion tank based on the system's water replenishment amount

C series: Combination of variable frequency and expansion tank with constant pressure water replenishment method
