Abstract

The invention relates to a water pump double-water-cooling structure. The structure comprises a machine shell (8), wherein a rotor (11), a stator (4) and a shield sleeve (9) between the rotor (11) andthe stator (4) are arranged in the machine shell (8), water cooling pipelines are arranged in the machine shell, and the water cooling pipelines comprise an inner water cooling pipeline and an outerwater cooling pipeline. According to the structure, the outer water cooling pipeline is arranged, circulation is realized in the outer water cooling pipeline under assistance of the outlet shield sleeve, so that the effects of cooling a driving plate and the stator are achieved; and the inner water cooling pipeline is arranged, the inner water cooling pipeline is mainly used for cooling the rotor,and particularly has the better effect on a permanent magnet rotor, the working temperature can be reduced, and the service life is prolonged.

Description

technical field [0001] The invention relates to a water pump cooling structure, in particular to a water pump double water cooling structure. Background technique [0002] A pump is a machine that transports or pressurizes a liquid. It transmits the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali, emulsion, suspoemulsion and liquid metal. [0003] The existing water pumps have the following defects. The driving part generates a lot of heat at a high speed, which will cause the instability of the water pump. If a cooling fan is used, it will have a large noise and is not quiet. [0004] In view of the above-mentioned defects, the designers are actively researching and innovating in order to create a dual-water cooling water pump with a new structure, so that it has more industrial utilization value.
