Intake flow guide device of centrifugal pump

Abstract

The invention discloses an intake flow guide device of a centrifugal pump. The device comprises a motor, wherein a junction box is fixedly connected to the left side surface of the motor; a rotating shaft is fixedly connected to the middle part of the bottom part of the motor; a protecting cover is fixedly connected to the bottom part of the motor, and the rotating shaft is positioned in the protecting cover; a first fixing plate is fixedly connected to one end, far away from the motor, of the protecting cover; two symmetric first thread holes are formed in the upper surface of the first fixing plate; a first bearing is fixedly embedded into the middle part of the upper surface of the first fixing plate; a second fixing plate is arranged at the bottom part of the first fixing plate; two symmetric second thread holes are formed in the upper surface of the second fixing plate; a second bearing is fixedly embedded into the middle part of the top part of the second fixing plate; threaded rods are arranged in the second thread holes; one end, close to the corresponding thread hole, of each threaded rod sequentially passes through the corresponding second thread hole and the corresponding first thread hole and extend to be above the first fixing plate. The intake flow guide device of the centrifugal pump has the advantages of preventing a pipeline from being blocked, facilitating a user to mount, and being suitable for market popularization and use.

Description

technical field [0001] The invention relates to the technical field of pumps, in particular to a suction deflector of a centrifugal pump. Background technique [0002] A pump is a machine that transports fluid or pressurizes the fluid. It transmits the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. The pump is mainly used to transport water, oil, acid and alkali, emulsion, suspoemulsion and Liquids such as liquid metals can also transport liquids, gas mixtures and liquids containing suspended solids. Pumps can usually be divided into three types according to their working principles: positive displacement pumps, dynamic pumps and other types of pumps. It can be classified and named according to other methods. For example, it can be divided into electric pumps and water wheel pumps according to the driving method, single-stage pumps and multi-stage pumps according to the structure, and can be divided into boil...
