Description
Technical Field
The invention relates to a water pump, in particular to a water pump structure with a quick suction lift.
Background
The centrifugal pump is a common water pump, and is filled with water before starting to discharge air in a pump cavity, when the centrifugal pump works, an impeller rotates, and water is thrown to the edge of the impeller under the action of centrifugal force, so that negative pressure is formed in the center of the impeller, the water is sucked in, and the water pumping function is realized. When the water pump just starts to operate, the state of water in the pump cavity is a water-gas mixture, the volume of water in the whole pump cavity is at a fixed value, mainly because the water pump inlet does not suck water, the water pump outlet does not discharge water, the water outlet pressure is insufficient, and the water inflow does not lead to the fact that the water in the pump cavity can not be discharged. Which directly affects the suction height and suction time of the pump. If air is sucked into the water inlet of the water pump in the working process, the density of the air is less than that of water, the centrifugal force generated by the air is less than that generated by the water, the air is gathered in the center of the impeller to prevent the water flow from being sucked, and the suction height is reduced.
