Blade surface rust stain treatment device for centrifugal pump maintaining

Abstract

The invention discloses a blade surface rust stain treatment device for centrifugal pump maintaining. The device comprises a treatment shell body, the inner wall of the bottom of the treatment shell body is rotatably connected with a rotating shaft, a thread hole is formed in the outer wall of the top of the rotating shaft, the inner wall of the thread hole is rotatably connected with a thread rodthrough a thread, a round block is mounted on the outer wall of the top of the thread rod, a round rod is arranged on the outer wall of the top of the round block, an extrusion ring is rotatably connected to the circumference outer wall of the round rod through a thread, the same screw is rotatably connected to the inner walls of the two sides of the treatment shell body, the circumference outerwall of the screw is rotatably connected with a sliding block through a thread, the rotating shaft, the thread rod, the round block and the extrusion ring on the round rod are arranged, before use, the round block matched with a blade is selected, and then is fixed to the rotating shaft, the blade is inserted into the round rod, the extrusion ring is used for fixing, the centrifugal pump blade canbe rapidly fixed, the fixing range can be widened, use by a worker is facilitated, and the subsequent blade rust stain treatment is facilitated.

Description

technical field [0001] The invention relates to the technical field of centrifugal pumps, in particular to a device for treating rust stains on the surface of blades for maintenance of centrifugal pumps. Background technique [0002] Centrifugal pumps have vertical, horizontal, single-stage, multi-stage, single-suction, double-suction, self-priming and other forms. Centrifugal pumps work by using the impeller to rotate to make water centrifugally move. Before the pump starts, The pump casing and the suction pipe must be filled with water, and then the motor is started, so that the pump shaft drives the impeller and the water to rotate at a high speed, the water undergoes centrifugal motion, is thrown to the outer edge of the impeller, and flows into the pressure of the pump through the flow channel of the volute pump casing. water line. [0003] Centrifugal pump blades are one of the important components of centrifugal pumps. In the process of maintenance and inspection of ...

AI Technical Summary

Problems solved by technology

[0003] Centrifugal pump blades are one of the important components of centrifugal pumps. In the process of maintenance and inspection of centrifugal pumps, it is necessary to remove rust stains on the surface of the blades. Now they are manually polished with sandpaper, which requires a lot of work and high efficiency. It is extremely low and inconvenient for people to use, so there is an urgent need for a centrifugal pump maintenance blade surface rust treatment device to solve the above problems
