Problems solved by technology

As the water pump is continuously washed by the medium during operation, the nuts and bolts fixing the impeller are easy to loosen. Once loosened, the impeller will rub against the diversion shells, so that the entire set of pump rotors will rotate together, causing the pump to malfunction and causing various parts in the pump to fail. All are damaged to varying degrees, which will expand the loss and seriously affect the normal operation of the pump.

Abstract

The invention discloses a multi-stage pump with an anti-rotation device. A strap is connected between an outlet guide casing and a guide seat; a first connecting piece is arranged at one end (of the strap) which is connected with the outlet guide casing; a second connecting piece is arranged at the outlet guide casing; and the first connecting piece and the second connecting piece are in threat fit. By adopting the technical scheme, the outlet guide casing and the guide seat are connected by the strap and tightened up by thread structure of the first connecting piece and the second connectingpiece so as to integrate all parts in the pump and enable the pump to be stable, so that the operation is reliable, the service life of the pump is long, the loss is reduced and the efficiency of thepump is improved.

Description

technical field [0001] The invention relates to a multistage pump, in particular to a multistage pump with an anti-rotation device. Background technique [0002] The guide seat, guide case and outlet guide case of the stainless steel stamping multi-stage pump are the fixed parts of the pump. In the existing multi-stage pump structure, the anti-rotation between the guide case mainly depends on the installation on the motor base and the base. The tension screw between the stages is used to fix the parts between the stages. Because the water pump is continuously washed by the medium during operation, the nuts and bolts fixing the impeller are easy to loosen. Once loosened, the impeller will rub against the diversion shells, so that the whole set of pump rotors will rotate together, causing the pump to malfunction and causing various components in the pump to fail. All are damaged to varying degrees, which enlarges the loss and seriously affects the normal operation of the pump...
