Guide vane type small-flow centrifugal pump

Abstract

The invention relates to a guide vane type small-flow centrifugal pump. The guide vane type small-flow centrifugal pump is suitable for use in the petroleum, petrochemical and chemical industries to convey low-temperature or high-temperature, inflammable, explosive and highly corrosive media which contains a small amount of particles or is clean. The guide vane type small-flow centrifugal pump ishorizontal and radially subdivided. The centrifugal pump comprises a pump body, a guide vane, an impeller, an impeller ring, a pump cover, a sealing part and a bearing part. The impeller ring is arranged on the impeller, the pump cover is arranged on the bearing part, and the impeller is arranged on a pump shaft and then is packaged on the pump cover through the guide vane to form an impeller working cavity. The pump body is fixedly connected with the pump cover through a bolt, the guide vane and the impeller are packaged between the pump cover and the pump body, and the sealing part is arranged between the pump shaft and the pump cover for sealing. According to the technical scheme, the problem that various pump bodies and impellers need to be researched and developed in the prior art tomeet requirements of different performance parameters is solved.

Description
