Conveniently detached type low noise water cooling pump

Abstract

The invention discloses a conveniently detached type low noise water cooling pump which comprises a centrifugal pump, a motor, a pump spindle, a motor shaft, a high-pressure return pipe, a coupler, a mechanical seal, a connecting frame, a low pressure return pipe, a motor outer shell, a cooling chamber, a motor lower bearing and a blind plate, wherein a pump spindle hole is formed in the pump spindle, a blind hole is formed in the motor shaft, one end of the high pressure return pipe is connected with the pump spindle hole, the other end of the high pressure return pipe is inserted into the blind hole of the motor shaft, the coupler is provided with a cavity and a coupler hole, and the connecting frame is provided with two symmetrical connecting frame holes with diameters more than or equal to 80 millimeters. The conveniently detached type low noise water cooling pump has the advantages of being capable of bringing great convenience for examining and repairing of the mechanical seal and the motor lower bearing, meanwhile adopting shaft cooling and motor outer shell cooling, improving working efficiency of the motor, reducing running noise of the unit and achieving excellent effects of high-efficiency, energy-saving, low-noise and environment-friendly.

Description

technical field [0001] The invention relates to a motor, in particular to a detachable low-noise water-cooled pump in an internal circulation water cooling mode used on a centrifugal pump. Background technique [0002] At present, the main structure of low-noise water-cooled pumps of some manufacturers is as follows: figure 1 As shown, the centrifugal pump 1 and the motor 2 share the same shaft 3, and the shaft cooling and motor casing cooling methods are used to reduce the heat emitted by the motor. Although the cooling effect is good, the mechanical seal of the water pump and the motor bearing are vulnerable parts. If it is damaged, all parts of the pump and the motor must be disassembled for replacement, which brings great difficulty to maintenance. [0003] In view of the above reasons, the research and development personnel have been looking for a method that can maintain the original shaft cooling and motor casing cooling while facilitating the replacement and mainten...
