Description

Technical Field

[0001] This utility model belongs to the field of self-priming pump technology, specifically a clog-resistant, air-cooled, circulating self-priming pump. Background Technology

[0002] Self-priming pumps are a type of self-priming centrifugal pump. They feature compact structure, convenient operation, stable running, easy maintenance, high efficiency, long service life, and strong self-priming capability. No foot valve is required in the pipeline; only a certain amount of priming liquid needs to be present in the pump body before operation. Different materials can be used for self-priming pumps of different liquids.

[0003] Existing self-priming pumps mainly consist of a pump motor, pump chamber, inlet, outlet, drive shaft, and centrifugal blades. When in use, the pump motor is started, which causes the drive shaft to drive the centrifugal blades to rotate, thereby assisting in water intake and discharge within the pump chamber by using centrifugal force.

[0004] However, in actual use, the pump motor will generate heat during operation. Relying on the traditional method of heat dissipation through the pump motor casing results in low overall heat dissipation efficiency, which can easily lead to overheating and the pump motor failing to function properly. Usually, an external air blower is used to cool the outer surface of the pump motor. However, blowing directly onto the casing means that the heat inside the pump motor still cannot be dissipated in time, which is very inconvenient. Utility Model Content
