Abstract
The utility model provides a novel impeller. The novel impeller comprises an impeller disc and a shell body, wherein the impeller disc is installed in the shell body, two ends of the shell body are respectively provided with a cover plate, an impeller mouth ring is arranged on the outer side of each cover plate, and a tungsten carbide layer is arranged on each impeller mouth ring. According to the novel impeller, due to the fact that the tungsten carbide layer is arranged on each impeller mouth ring, mechanical occlusal force between the impeller and sealing rings is reduced, friction is reduced, the impeller is prevented from getting stuck, efficiency of a water pump is improved, wear resistance is improved, the service lives of the impeller and the sealing rings are prolonged, the structure is simple, and manufacturing is convenient.
Description
Technical field
The utility model relates to pump part, especially relates to a kind of novel impeller.
Background technique
Water pump is widely used in industry and the life, and when using, people can select the use material of each parts of water pump according to water quality condition and service condition.In Korrosionsmedium, the material of impeller and seal ring is selected stainless steel usually for use, because there is certain roughness in working surface, has mechanical snap power between impeller and seal ring.When pump operation, can cause impeller and seal wears to be accelerated, pump efficiency reduces, and produces a large amount of heats, when serious even can cause the impeller stuck phenomenon.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of novel impeller, can reduce the mechanical snap power between impeller and seal ring, the power of reducing friction, solve the impeller stuck phenomenon, improve pump efficiency, improve wear-resisting property, strengthen the working life of impeller and seal ring.
For achieving the above object, the utility model proposes provides a kind of novel impeller, comprises the impeller plate and housing, the described impeller plate is installed in the housing, described housing two ends are respectively equipped with cover plate, and the outside of described cover plate is provided with impeller port ring, and described impeller port ring is provided with carbide layers.
As preferably, the thickness of described carbide layers is 0.1～0.3mm, improves wear-resisting property, increases working life.
The beneficial effects of the utility model: adopt carbide layers at impeller port ring, can reduce the mechanical snap power between impeller and seal ring, the power of reducing friction, solve the impeller stuck phenomenon, improve pump efficiency, improve wear-resisting property, strengthen the working life of impeller and seal ring, simple in structure, easily manufactured.
