Background

The self-priming pump belongs to a self-priming centrifugal pump and has the advantages of compact structure, convenient operation, stable operation, easy maintenance, high efficiency, long service life, stronger self-priming capability and the like. The pipeline does not need to be provided with a bottom valve, and only quantitative liquid guiding is required to be ensured to be stored in the pump body before work. The self-sucking pump is characterized in that the pump shell is filled with water (or water is stored in the pump shell) before the water pump is started. After the impeller is started, the impeller rotates at a high speed to enable water in the impeller channel to flow to the volute, at the moment, the inlet forms vacuum, the water inlet check valve is opened, and air in the suction pipe enters the pump and reaches the outer edge through the impeller channel.

When the self priming pump is used for blowdown, because contain a large amount of rubbish silt in the sewage, directly absorb sewage and get into the pump body and cause the pump body to block up the damage easily, for avoiding blockking up the pump body, often can install filter equipment in the water inlet department of the pump body, nevertheless under the too much condition of rubbish, need clear up filter equipment, need close the pump machine during the clearance, wait to clear up and need restart after accomplishing, lead to the energy extravagant, and reduce work efficiency.

Wherein the patent number is CN209324677U, discloses a blowdown self priming pump of exempting from to shut down clearance, including the pump body, driving motor and fixed baseplate, the pump body and driving motor fixed mounting are on fixed baseplate upper portion, driving motor's pivot stretch into in the pump body with impeller fixed connection, pump body side is equipped with the suction interface, suction interface connection rose box bottom, rose box fixed mounting is on fixed baseplate, rose box inside divide into two cavities through the division board symmetry, the suction interface is respectively through two cavities of connecting pipe connection rose box, two cavity opposite sides of rose box are connected with the guiding tube respectively, the guiding tube other end is connected on the suction tube, manual valve is installed respectively in guiding tube and connecting pipe middle part.

Although the function of cleaning without stopping the machine can be realized in the scheme, more manual valves can be used if filter tanks with meshes of different diameters are needed, the phenomenon of control error is easy to occur, and the space for placing the filter tanks on the base is limited.
