The principle of how inverters work in constant pressure water supply: Constant pressure water supply is an indispensable part of daily life. Traditional methods for achieving constant pressure water supply involve the use of fixed-speed pumps, water towers, jet pumps, elevated water tanks, pressure vessels, and other facilities. With the improvement of frequency conversion speed regulation technology, the integration of inverters, PID controllers, PLC, and other components to form a control system can regulate the output flow of pumps, thereby achieving constant pressure water supply. Utilizing inverter speed control technology can significantly enhance efficiency.

I. The role of variable frequency constant pressure water supply systems

1. Effective energy saving, which can achieve electricity savings of 20%-40%, greatly reducing corporate costs.

2. Flexible configuration with high automation, flexible reliability, comprehensive functions, and easy operation.

3. Small footprint, low investment, and high efficiency.

4. Rational operation; soft start and stop can eliminate the water hammer effect, reduce wear, and extend the service life of pumps.

5. Due to direct water supply from the source using variable frequency constant pressure speed control, it reduces secondary pollution from traditional water supply methods, avoiding many sources of infectious diseases.

6. Through communication control, it can achieve unmanned operation, saving labor and resources, and being highly intelligent.

7. Stable water supply pressure, closed-loop control system,, automatically adjusts the difference between the set pressure and system pressure.

8. Advanced technology, high degree of automation, capable of realizing intelligent constant pressure variable flow water supply according to various water supply requirements.

II. Main applications of variable frequency speed regulation constant pressure water supply equipment

1. High-rise buildings, residential areas, communities, enterprises, and institutions for domestic water.

2. Central air conditioning systems.

3. Various industrial applications requiring constant pressure control, cooling water circulation, thermal network water circulation, boiler makeup water, etc.

4. Farmland irrigation, sewage treatment, artificial fountains.

5. Water supply augmentation systems for water plants.

6. Various fluid constant pressure control systems.
