Self-sucking energy-saving high-efficiency water pump

Abstract

The invention discloses a self-sucking energy-saving high-efficiency water pump, which comprises an impeller and a pump shell, wherein the impeller is positioned in a liquid chamber of the pump shell and connected to a driving device which drives the impeller to rotate to form a water current for water pumping; the liquid chamber has a water inlet and a water outlet; the impeller comprises a hub and blades; the liquid chamber is eccentrically arranged relative to the hub; one side of the hub is close to the inner wall surface of the liquid chamber, so the volume between the other side of the hub and the inner wall surface of the liquid chamber is big, the water inlet of the liquid chamber is communicated with the large volume area and the water outlet of the liquid chamber is communicated with the position, where the volume reduces gradually, of the liquid chamber; and the blades can be moveably arranged in the hub relative to the hub. When the hub rotates, the blades extend outwards under the action of the centrifugal force, the tail ends of the blades are matched with the inner wall surface of the liquid chamber and extend radially along with the volume change of the liquid chamber to drive the water current, and thus, the water current flows towards the water outlet only. The self-sucking energy-saving high-efficiency water pump avoids the diffusion and reflux of the water current, improves the pumping efficiency and the flow and has the advantages of saving the energy and protecting the environment.

Description

Self-priming energy-saving and high-efficiency water pump technical field The invention relates to the technology in the field of water pumps, in particular to a water pump that utilizes the cooperation of an eccentric liquid chamber and movable blades to obtain high-efficiency water pumping. Background technique At present, water pumps have been widely used in water circulation such as electronic refrigerators, ice bladders, hot water bottles, aquarium fish tanks, fountains, solar energy and handicrafts. The structure of the water pump is basically composed of a pump casing and an impeller, and is used with a motor. The pump casing is provided with a water inlet and a water outlet. The impeller is set in the liquid chamber of the pump body, and the outlet is connected to the side of the liquid chamber. The direction of the outlet is consistent with the tangential direction of impeller rotation. Its working principle is to use the motor to drive the impeller to rotate at ...
