Mixed-flow pump with flow guide device and height-adjustable base

Abstract

The invention relates to the technical field of mixed-flow pumps, and discloses a mixed-flow pump with a flow guide device and a height-adjustable base. The mixed-flow pump comprises a mixed-flow pumpmain body, a top ring is fixedly mounted at the top of the mixed-flow pump main body, an impeller is fixedly mounted on the front surface of the mixed-flow pump main body, a transmission frame is fixedly mounted on the front surface of the mixed-flow pump main body, a transmission hole is formed in the transmission frame, and a drainage pipe is fixedly installed at the bottom of the mixed flow pump body. According to the mixed-flow pump with the flow guide device and the height-adjustable base, a threaded adjusting rod is arranged, a threaded adjusting hole corresponding to the threaded adjusting rod is formed in a bearing plate, and adjusting threads corresponding to the threaded adjusting rod are formed in the inner wall of the threaded adjusting hole and the outer surface of the threaded adjusting rod, so that through rotating the threaded adjusting rod, the effect of adjusting the height of the mixed-flow pump main body is achieved; and meanwhile, a supporting frame and an adjusting sleeve are arranged, so that the problem that the mixed-flow pump main body rotates together in the rotating process of the threaded adjusting rod is solved.

Description

technical field [0001] The invention relates to the technical field of mixed-flow pumps, in particular to a mixed-flow pump with a flow guiding device and a height-adjustable base. Background technique [0002] A mixed flow pump is a pump between a centrifugal pump and an axial flow pump. The specific speed of the mixed-flow pump is higher than that of the centrifugal pump and lower than that of the axial-flow pump, generally between 300-500. Its head is higher than that of axial flow pump, but its flow rate is smaller than that of axial flow pump and larger than that of centrifugal pump. [0003] Traditional mixed-flow pumps are all fixed on the base, and the height of the base cannot be adjusted according to requirements, resulting in insufficient application. Chinese patent CN 110792625 A proposes a mixed-flow pump with a height-adjustable base. The height adjustment device consists of The control of two telescopic rods cannot guarantee the synchronous adjustment of the...
