The role of impeller in water pump
The impeller is driven by electric motor rotation, the middle impeller creates a vacuum to vacuum at the inflow of water will be (on the surface water is continuously sucked into the impeller), then the water through the high-speed rotation of the impeller of the water discharge, play a promoting role in water.
Pump impeller through the motor to drive rotation, so that the medium (water) by centrifugal force or lifting force, so that the medium has mechanical energy (kinetic energy)
The impeller rotates at high speed so that the centrifugal force is generated by the water, and the vacuum is generated in the middle of the impeller, and the water source is continuously sucked into the impeller to increase the kinetic energy of water and play a role in promoting water.
