Description

Technical Field

[0001] The utility model relates to the technical field of motor brackets, in particular to a noise reduction platform for a self-priming pump. Background Art

[0002] The self-priming pump belongs to a self-priming centrifugal pump. It has the advantages of compact structure, convenient operation, stable operation, easy maintenance, high efficiency, long life, and strong self-priming ability. The pipeline does not need to be installed with a bottom valve. Before working, it is only necessary to ensure that a certain amount of liquid is stored in the pump body. Different materials can be used for different liquids. Self-priming pumps of different materials transmit the mechanical energy of the prime mover or other external energy to the liquid to increase the liquid energy. It is mainly used to transport liquids. Water pumps are widely used in agriculture, production and other life fields. The working principle of the self-priming pump is that the pump casing is filled with water (or there is water in the pump casing itself) before the water pump is started. After starting, the impeller rotates at a high speed to make the water in the impeller groove flow to the volute. At this time, a vacuum is formed at the inlet, so that the water inlet check valve is opened, and the air in the suction pipe enters the pump and reaches the outer edge through the impeller groove. Since the self-priming pump will shake when it is working, it will collide with the platform to generate a large noise, and it will also cause the fixing bolts to be easily loosened. Based on this, the utility model designs a self-priming pump noise reduction platform to solve the above problems. Utility Model Content
