The working principle of single stage centrifugal pump

The reason why the centrifugal pump can send the water out is due to the centrifugal force. Before the pump works, the pump body and the water inlet pipe must be filled with water to form a vacuum state. When the impeller rotates rapidly, the blades promote the rapid rotation of the water, and the rotating water flies away from the impeller under the action of centrifugal force, and the water in the pump is removed After being thrown, the central part of the impeller forms a vacuum area. The water of the water source is pressed into the water inlet pipe through the pipe network under the action of atmospheric pressure (or water pressure). This cycle is endless, and continuous pumping can be achieved. It is worth mentioning here that the centrifugal pump must be filled with water in the pump casing before starting, otherwise the pump body will not be able to complete the suction, causing the pump body to heat up, vibrate, and produce no water, resulting in "idling". Damage to the water pump (referred to as "air binding") causes equipment accidents.
