Water pumps are generally designed based on the maximum operating requirements of the water supply system. In actual use, the water system may not always reach the maximum water usage. Generally, valve adjustment increases the system resistance to throttle, resulting in power loss in the motor. Using a frequency converter can make the system work smoothly and stably, and by changing the speed to adjust the water supply, power consumption can be greatly reduced.
Centrifugal water pumps are widely used in refrigeration and air conditioning, water treatment plants, water supply systems, cooling systems, etc. Their characteristics are that they rely on the high-speed rotation of the impeller to make the fluid obtain greater kinetic energy, and rely on the change of the spiral cross-section at the flow channel outlet to convert the kinetic energy of the fluid into pressure energy. The flow of water in the impeller is mainly affected by centrifugal force
