Abstract

The invention discloses a pipeline pump. The pipeline pump comprises a pump body, a pump cover, a motor and an impeller arranged in the pump body. The opening end of the pump body is covered with the pump cover. A motor base is arranged at the other end of the pump body. The motor is installed on the upper surface of the motor base. A coupling, a shaft and a bearing seat supporting the shaft are arranged in the motor base. An output shaft of the motor is connected with the upper end of the coupling. The lower end of the coupling is connected with the upper end of the shaft. The lower end of the bearing seat is fixedly connected with the pump cover. The lower end of the shaft penetrates through the pump cover and is connected with the impeller. A sealing assembly is installed in the position, adjacent to the pump cover, of the shaft. A pump body sealing ring is installed in the position, adjacent to the pump cover, of the pump body. The pipeline pump is convenient to dismantle, safe, reliable, good in sealing performance, and long in service life.

Description

technical field [0001] The invention relates to pumps for conveying liquid medium, in particular to a pipeline pump. Background technique [0002] The pipeline pump is a vertical pump, and the center of the inlet and outlet is on the same vertical line as the pump shaft. Pipeline pumps have the advantages of compact structure, small footprint, and can be directly installed in pipelines, so they have been more and more widely used in recent years. However, the existing pipeline pump adopts a rigid direct connection structure between the pump and the motor. The assembly of the pump is difficult, the axial thrust of the pump is large, and the bearings of the motor are prone to heat and burnt. In addition, when replacing the seal or guide bearing, the motor wiring must be removed. , Coupling, motor base, pump cover and impeller and other components, the maintenance workload is heavy. Contents of the invention [0003] The technical problem solved by the present invention is ...
