Description

Water pump heat radiation structure

Technical Field

The utility model belongs to the technical field of the water pump heat dissipation, concretely relates to water pump heat radiation structure.

Background

Water pumps are machines that deliver or pressurize a liquid. It transfers the mechanical energy of prime mover or other external energy to liquid to increase the energy of liquid, and is mainly used to transfer liquid including water, oil, acid-base liquid, emulsion, suspoemulsion and liquid metal.

The principle of the centrifugal water pump is that water is filled into the pump before starting, the impeller which rotates after starting drives the water in the pump to rotate at high speed, and the water is centrifugally moved, thrown out outwards and pressed into a water outlet pipe. After the water is thrown out, the pressure near the impeller is reduced, and a low-pressure area is formed near the rotating shaft. The pressure is much lower than the atmospheric pressure, and the outside water can open the bottom valve and enter the pump from the water inlet pipe under the action of the atmospheric pressure. The water which is rushed in is thrown out again in the high-speed rotation along with the impeller and is pressed into the water outlet pipe. The impeller is driven by the power machine to rotate at a high speed continuously, water is continuously pumped from a low position to a high position, and the temperature of components with poor heat resistance, such as windings, stator core laminations and the like, can be increased due to energy loss in the operation of the motor of the traditional centrifugal water pump. Therefore, when the environment temperature of the water pump is too high, the temperature generated by the motor during working cannot be dissipated in time, so that the temperature rise of a motor winding of the water pump is caused, the service life of insulation materials can be further shortened, the temperature rise of the motor exceeds the standard, and the motor breaks down. Therefore, a heat dissipation structure is needed to ensure that the motor of the water pump can work normally when the ambient temperature is too high.

An effective solution to the problems in the related art has not been proposed yet.
