Abstract
The invention relates to a swirl self-priming pump. The swirl self-priming pump comprises a pump body, an impeller, a bearing component, a pump cover, a flow passage lining plate, and a front end cap. The interior of the pump body is divided into a water suction chamber, an extrusion chamber, a fluid reservoir, and an air water separating chamber. The impeller and the bearing component are connected with ends inside the extrusion chamber. A chamber without vanes is formed between the impeller and the flow passage lining plate. The impeller comprises a plurality of vanes distributed around the rotation center of the impeller. The vanes comprise connection portions close to the rotation center and working portions far away from the rotation center. The width of the working portions is greater than that of the connection portions. An annular groove is arranged on the flow passage lining plate in the position relative to the working portions, thereby forming enough circulation flow areas among the vanes and the flow passage lining plates. The air water separating chamber is located above the fluid reservoir and is communicated with the fluid reservoir. The flow passage of the extrusion chamber passes through the air water separating chamber and is communicated with an output pipeline that is connected on the pump body. In the using process of the swirl self-priming pump, solid objects are mostly removed by the chamber without vanes, and the solid objects cannot enter the impeller to abrade the impeller.
