Problems solved by technology

However, this equipment ignores that during the operation of the impeller, due to the poor torque resistance of the shaft hole, the wear efficiency of the shaft hole is fast and the deformation is easy to occur, which greatly reduces the service life of the impeller

Abstract

The invention discloses a quick-wear impeller long in service life. The quick-wear impeller comprises an impeller plate, a hub, blades and a shaft hole and is characterized in that the hub is arrangedon the impeller plate, the blades are arranged on the outer side of the hub and integrated with the impeller plate, the shaft hole is arranged in the center of the impeller plate, a bush fixedly connected with the shaft hole is arranged in the shaft hole, more than more racks integrated with the bush are evenly distributed on the outer surface of the bush, longitudinal grooves are formed among the racks, and the upper end of the shaft hole is provided with an annular sleeve fixedly connected with the shaft hole. The impeller has the advantages that the torque resistance of the impeller is increased through the bush arranged in the shaft hole, the service life of the impeller is prolonged greatly, and the impeller is good in usability and simple in structure.

Description

technical field [0001] The invention relates to a consumable impeller with long service life. Background technique [0002] The impeller is an important working part of the water pump. It is made of cast iron and is easily damaged due to manufacturing quality and use, so it is called a vulnerable impeller. A conventional water pump impeller includes a shaft hole, a hub and a blade connected to the hub. The blade is a smooth curved surface with a certain radian. The smooth curved blade can reduce the resistance to water flow during the flow of water, but in the same circumferential radius and Under the premise of the same speed, the flow rate and head of the arc-shaped impeller are relatively small, which cannot meet the requirements of high head and large flow. [0003] The disclosed technology of a water pump impeller structure in this application with the publication number CN204476845U has solved the above-mentioned problems. The blade is composed of an arc part and a st...
