Description

Technical Field

[0001] The utility model belongs to the technical field of self-priming pumps, in particular to a self-priming pump which is easy to maintain. Background Art

[0002] The self-priming pump is a self-priming centrifugal pump with 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 there is a certain amount of liquid in the pump body. Different materials of self-priming pumps can be used for different liquids.

[0003] When the self-priming pump is performing water pumping operations, due to the various debris particles in the water, and the lack of filtering structure in the traditional self-priming pump, the self-priming pump is easy to suck the impurities in the water into the pump body during operation, resulting in damage to the rotating impeller and the pump body, which in turn reduces the service life of the self-priming pump and is inconvenient to maintain. Therefore, we propose a self-priming pump that is easy to maintain to solve this problem. Utility Model Content

The outer wall of the separation cylinder 5 is on the right The side seal is connected with an extraction pipe 8, and the cross section of the extraction pipe 8 is an "L"-shaped structure. One end of the extraction pipe 8 can penetrate into the water to be extracted.

A spiral rod 11 is arranged inside the centrifugal cavity 3, and one end of the spiral rod 11 is fixedly connected to the right central position of the centrifugal disc 10, which can keep synchronous rotation when the centrifugal disc 10 rotates. The spiral rod 11 can produce a pull-back effect on the water flow during the rotation process, thereby improving the water intake efficiency inside the centrifugal cavity 3;

[0026] The separation cylinder 5 is connected to the right side of the centrifugal chamber 3 through a pipeline seal. An anti-blocking component is arranged inside the separation cylinder 5 to intercept particulate debris in the extracted water and prevent it from entering the centrifugal chamber 3. The anti-blocking component includes a filter screen 13, a rotating fan blade 14 and a guide worm 15. The filter screen 13 is arranged on the left side of the interior of the separation cylinder 5, and the internal cross-section of the filter screen 13 is an "L"-shaped structure. The rotating fan blade 14 is rotatably connected to the upper end of the interior of the separation cylinder 5 through a rotating shaft, and the rotating fan blade 14 is kept at the same level as the extraction pipe 8. The center line, the guide worm 15 is fixed at the lower end of the rotating shaft, and one end of the guide worm 15 extends toward the sewage pipe 9.
