Abstract

The invention relates to the field of impellers and discloses a high-lift pump impeller for an electric automobile. The high-lift pump impeller for the electric automobile comprises an impeller body (2) installed in a pump body, the impeller body (2) comprises a panel (3) and blades (4) installed on the panel (3), the blades (4) comprise main blade bodies (41) and auxiliary blade bodies (42), themain blade bodies (41) and the auxiliary blade bodies (42) are circumferentially arranged round the central axis of the panel (3), and the length of the main blade bodies (41) is larger than that of the auxiliary blade bodies (42). According to the high-lift pump impeller for the electric automobile, the two kinds of blade bodies are arranged, so that the flow area between the blades is increased;since bending of the blades is reduced and jamming of the blades is also reduced, the circulation area of the blades is increased; and the inlet flow speed is reduced, so that the anti-cavitation performance of the impeller is improved.

Description

technical field [0001] The invention relates to the field of impellers, in particular to a high-lift water pump impeller for electric vehicles. Background technique [0002] At present, there are three circulation systems on new energy pure electric buses that require electric water pumps, motor cooling systems, battery thermal management systems, and air-conditioning and heating systems; among them, the pipelines of the air-conditioning and heating systems and battery thermal management systems are relatively complicated, and the water resistance of the system is very high. . [0003] Existing high-lift electric water pumps often have relatively large motor power and large water inlet and outlet ports, and usually do not operate under rated conditions, resulting in serious energy loss. Contents of the invention [0004] The invention provides a high-lift water pump impeller for an electric vehicle, aiming at the disadvantages of the high-lift electric water pump in the p...
