Position-adjustable high-speed centrifugal pump inlet device

Abstract

The position-adjustable high-speed centrifugal pump inlet device comprises a shell, a mounting plate is arranged on one side of the shell, a first groove is formed in the shell, a rotating shaft is arranged in the middle of the interior of the first groove, a connector is arranged in the middle of the rotating shaft, a communicating hole is formed in one side of the connector, and a water conveying hose is arranged on one side of the communicating hole. The end of the rotating shaft penetrates into the inner wall of the first groove to be connected with a driving mechanism, the driving mechanism comprises a driving groove located in the inner wall of the first groove, and the end of the rotating shaft penetrates into the driving groove to be connected with a first gear and a second gear. The device has the beneficial effects that through the design of a first meshing block and a second meshing block, movement reset of a limiting block is slowed down, so that rotation adjustment time is provided for a first gear, and a pushing plate conveniently pushes the first gear to rotate; and therefore, the contraction and reset time of the limiting piece is just consistent with the time required by the pushing claw and the pushing plate to push the gear I to rotate and advance.

Description

technical field [0001] The invention relates to the technical field of centrifugal pump accessories, in particular to a position-adjustable high-speed centrifugal pump inlet device. Background technique [0002] High-speed pumps, also known as high-speed partial flow pumps, are a type of centrifugal pump. The basic working principle of the high-speed pump is similar to that of the ordinary centrifugal pump. It achieves the purpose of high lift by increasing the rotational speed of the impeller and increasing the linear velocity of the fluid at the outer edge of the impeller, eliminating the shortcomings of most multi-stage pumps. [0003] In use, the applicable working environment of the centrifugal pump is relatively complex, and it may be necessary to connect with pipes of different angles, but the connection port of the centrifugal pump cannot be adjusted in corresponding angular position. [0004] For the problems in the related technologies, no effective solutions hav...
