Technical Field
[0001] The utility model belongs to the technical field of water pumps, and relates to a self-priming pump, in particular to a water-cooled heat dissipation and anti-backflow self-priming pump. Background Technique
[0002] A self-priming pump, also known as a self-priming centrifugal pump, is a water pump with a special design that can automatically suck liquid under non-hydraulic conditions and transport it to a higher place. It has the advantages of compact structure, convenient operation, stable operation, easy maintenance, high efficiency, long service life, etc.
[0003] The traditional self-priming pump realizes the function of pumping and draining water by driving the impeller in the pump body to rotate through an electric motor. However, the electric motor is prone to overheating after long-term operation, resulting in a reduction in work efficiency. Summary of the Invention
[0004] The purpose of the utility model is to provide a highly efficient water-cooled heat dissipation and anti-backflow self-priming pump for the above problems existing in the prior art.
[0005] The purpose of the utility model can be achieved by the following technical solutions: A water-cooled heat dissipation and anti-backflow self-priming pump, characterized in that it includes a water pump main body composed of a pump body and an electric motor. The pump body is provided with a water inlet and a water outlet. The water inlet and the water outlet hole are provided with a water inlet connecting pipe and a water outlet connecting pipe, and the water inlet connecting pipe and the water outlet connecting pipe are provided with drainage branch pipes. A detachable connecting hose is provided between the drainage branch pipes. A plurality of heat dissipation fins are provided on the electric motor, and a plurality of hose clamping grooves are provided on the heat dissipation fins. The connecting hose is clamped in the hose clamping grooves.
[0006] In the above-mentioned water-cooled heat dissipation and anti-backflow self-priming pump, a one-way valve piece is provided in the water inlet connecting pipe, a reset torsion spring is provided on the one-way valve piece, and a limiting part for limiting the one-way valve piece is provided in the water inlet connecting pipe.
[0007] In the above-mentioned water-cooled heat dissipation and anti-backflow self-priming pump, an extension part of the drainage branch pipe is provided in the water outlet connecting pipe, and the extension part is vertically upward.
[0008] In the above-mentioned water-cooled heat dissipation and anti-backflow self-priming pump, connecting threads are provided on both the water outlet and the water inlet.
[0009] Compared with the prior art, in this water-cooled heat-dissipating anti-backflow self-priming pump, the water liquid is guided by the diversion branch pipe, and the water liquid surging in through the water inlet flows through the connecting hose, absorbs the heat generated by the motor through the connecting hose to achieve the purpose of heat dissipation. At the same time, the check valve piece arranged in the water inlet connecting pipe can prevent the water liquid from flowing back, so that it is not necessary to inject water for starting when starting repeatedly. The cooled water liquid enters the water outlet connecting pipe and is sprayed along the vertically upward extension part, further increasing the water output. After the detachable connecting hose is disassembled, it is convenient to inject water liquid into the pump body to assist in starting. BRIEF DESCRIPTION OF THE DRAWINGS
