The impeller of the energy-saving water pump adopts a three-dimensional flow impeller, which is specially designed according to the actual operating conditions. It can ensure that the energy-saving water pump operates in the efficiency zone. However, the impeller of the ordinary water pump has not been designed, and it is difficult to meet the on-site needs. It is impossible to ensure that the water pump works in the efficiency zone, resulting in energy waste.
The inlet and outlet and flow channel of the energy-saving water pump have been specially processed, which can effectively utilize the inlet pressure of the energy-saving water pump. Compared with ordinary water pumps, the energy-saving water pump has the following advantages.
1. After the inlet and outlet and flow channel of the energy-saving water pump have been specially processed, the water flow can flow smoothly into the volute. The adjusted energy-saving water pump has higher cavitation performance and higher efficiency.
2. The rotor weight of the energy-saving water pump is reduced, the radial force of the pump group is reduced, and the bearing life is increased.
3. The speed of the pump group is increased, the energy-saving water pump runs more smoothly, and the bearing life is increased.
4. Reduce the rotor operation disturbance value and reduce the wear and consumption of the impeller mouth ring.
5. Reduce seal wear and extend service life.
6. The three-dimensional flow theory and hydraulic model design are adopted to improve the impeller efficiency.
7. The impeller surface is machined, and the impeller flow is precision cast to improve the impeller flatness in all directions and reduce hydraulic loss.
8. The energy-saving water pump can effectively reduce the volume loss, mechanical and hydraulic loss in the process of conveying liquid.
