It will be a great pleasure to swim in the pool in a hot summer. However, some people ask how to keep the pool clean. Today, the editor will introduce you the working principle of the swimming pool circulating pump.

Working principle of pool circulating water pump

Working principle of swimming pool circulating water pump: water pump is composed of pump impeller, pump volute, motor and pump shaft connecting impeller center and motor. The impeller of a water pump is generally composed of two circular cover plates. There are several curved blades between the cover plates. The channel between the blades is a water passage groove. There is a round hole in the center of the front cover plate of the impeller, which is the water inlet of the impeller. When working, first open the water pump inlet pipe valve to make the water fill the pump shell. Then, connect the power supply of the motor, and the motor drives the water pump impeller to rotate at high speed (usually 1450 / 2900 RPM).

At this time, the water is thrown out of the impeller by centrifugal force, and is pressed to the outlet pipe of the pump through the vortex cover in the volute shell. At the same time, the water in the pool is continuously sucked into the center of the impeller along the suction pipe (return pipe) of the pump under the action of atmospheric pressure. Under the action of high-speed rotation of the impeller, the water is thrown out of the impeller and input into the pressure pipe connected with the outlet of the pump, thus forming a continuous water delivery from the pump.
