The present application may be further configured in a preferred example to: the rotor also comprises a core body, and the core body is arranged in a sealing way.

Through adopting above-mentioned technical scheme, the core body that seals the setting can reduce the corruption of cooling water to the core body.

The present application may be further configured in a preferred example to: one end of the diversion hole is positioned at the water inlet of the pump cavity, and the communication part of the pump cavity and the rotor cavity is far away from the water inlet of the pump cavity.

By adopting the technical scheme, in use, one end of the diversion hole in the pump cavity is in a low pressure area, and the communication part of the pump cavity and the rotor cavity is in a high pressure area, so that cooling water in the rotor cavity can form circulation, and a good cooling effect is achieved on the rotor.

The present application may be further configured in a preferred example to: the rotary shaft is fixedly connected with a revolute pair, the pump body and the casing are provided with a fixed pair, and the revolute pair and the fixed pair are matched to realize rotation of the rotary shaft.

Through adopting above-mentioned technical scheme, because the existence of revolute pair and fixed pair, and the rotation of pivot is realized to the cooperation of both, consequently there is liquid between revolute pair and the fixed pair, and then can effectively reduce the wearing and tearing of both and noise reduction.

The present application may be further configured in a preferred example to: the casing is also provided with a flow guide cavity which is communicated with the rotor cavity through a gap between the fixed pair and the rotating pair.

By adopting the technical scheme, in use, liquid can be better filled between the revolute pair and the fixed pair, so that the abrasion of the revolute pair and the fixed pair can be effectively reduced, and noise is reduced.

Detailed Description

The present application is described in further detail below with reference to the accompanying drawings.

Referring to fig. 1 and 2, a water-cooled water pump disclosed in the application comprises a pump body 1 and a motor 2, wherein the pump body 1 is arranged on the motor 2, and a pump cavity 12 for accommodating an impeller is arranged on the pump body 1. The motor 2 comprises a casing, a stator cavity 21 and a rotor cavity 22 which are not communicated with each other are arranged in the casing, a stator is arranged in the stator cavity 21, and a rotor is arranged in the rotor cavity 22. The pump body 1 is provided with a communication hole 11, the communication hole 11 is positioned on the cavity wall of the pump body 1, which is close to the rotor cavity 22, one end of the communication hole 11 is communicated with the pump cavity 12, and the other end is communicated with the rotor cavity 22.

The rotor includes pivot 32 and installs the core 31 on pivot 32, and the core 31 seals the setting, still fixedly connected with two revolute pairs 42 on the pivot 32, respectively installs the fixed pair 41 that cooperates with revolute pair 42 on the pump body 1 and the casing and use, and in this embodiment, revolute pair 42 and friction pair are ceramic material.
