Variable frequency constant voltage system

1、 Principles for selecting variable frequency constant voltage systems

(1) The capacity of the reservoir should be greater than the maximum water supply per hour

(2) The head of the water pump should be greater than the actual water supply height

(3) The total flow rate of the water pump should be greater than the actual maximum water supply

(4) Selection of frequency conversion control cabinet:

Users can determine the model and number of water pumps based on the water supply volume and height, and then select the appropriate control cabinet

2、 Application scope

1. This system can be used for both production and domestic water use, as well as for hot water supply, constant pressure spraying, and other systems

a. It can be widely used in industrial enterprises, daily life, production water supply systems, and self owned and renovated projects of enterprises, as well as in water plants, residential areas, and fire water supply systems

b. Can be used for constant pressure, variable pressure, cooling water, and circulating water supply systems in various occasions

c. Can be used forsewage pumpStation, sewage treatment and sewage improvement system

d. Can be used for agricultural irrigation, garden spraying, water features, and music fountain systems

e. Can be used for water supply and fire protection systems in hotels and large public buildings

2. Technical indicators

a. Maximum water supply height: 200 meters

b. Maximum flow rate: 1000 cubic meters per hour

c. Pressure fluctuation: ≤ 0.25 megapascals. Pump motor power: 0.75KW-280KW
