A steam turbine rotor descaling box and descaling method thereof

Abstract

The invention discloses a steam turbine rotor descaling box, which comprises a bottom plate, an operation platform is fixedly arranged on the upper surface of the bottom plate, a descaling box body is fixedly installed on the upper surface of the bottom plate, the operation platform and the descaling box body Fixedly connected, the inner wall of the descaling box is fixedly equipped with a fixed frame, and the upper surface of the operating table is fixedly provided with a pushing mechanism. Compared with the existing technology, the cleaning liquid sprayed out by the high-pressure spray gun body falls On the upper surface of the steam turbine rotor and flows to the inside of the descaling box, the filter plate filters the dirt in the cleaning solution, and makes the clean cleaning solution flow to the lower surface of the filter plate through the filter holes on the surface, and then the clean cleaning solution is cleaned by the water pump. The cleaning liquid is transported to the inside of the high-pressure spray gun body, which conveniently completes the filtration of the cleaning liquid and the recycling of the filtered cleaning liquid, thereby saving the cleaning liquid required in the cleaning and descaling process and reducing the cleaning and descaling The cost of the turbine rotor.

Description

A kind of steam turbine rotor descaling box and descaling method technical field The present invention relates to steam turbine rotor descaling technical field, be specially a kind of steam turbine rotor descaling box and descaling method thereof Law. Background technique Steam turbine rotor: a combination of steam turbine rotating parts such as main shaft, impeller or rotating drum, moving blade and coupling It is the main equipment of modern thermal power plants, and is also used in metallurgical industry, chemical industry, and ship power plants. current technology The steam turbine rotor descaling box has the following problems during descaling: 1, when the steam turbine rotor descaling box in the prior art is descaled, because the weight of the steam turbine rotor is heavier, it is difficult to Placing the turbine rotor inside the descaling box is very inconvenient to operate; 2, when the steam turbine rotor descaling box in the prior art is descaled, usual...

AI Technical Summary

Problems solved by technology

[0003] 1. When descaling the steam turbine rotor descaling box in the prior art, due to the heavy weight of the steam turbine rotor, it is difficult to place the steam turbine rotor inside the descaling box, and the operation is very inconvenient;

[0004] 2. The steam turbine rotor descaling box in the prior art can usually only place the steam turbine rotor to be cleaned and descaled on the surface of the descaling box. Since the steam turbine rotor to be cleaned and descaled cannot be rotated, the steam turbine The cleaning and descaling of the rotor is inconvenient and the efficiency of cleaning and descaling is relatively low;

[0005] 3. When descaling the steam turbine rotor descaling box in the prior art, most of the hand-held high-pressure spray guns are aimed at the surface of the steam turbine rotor to clean and descale the steam turbine, which leads to a waste of a lot of manual work time;

[0006] 4. The steam turbine rotor descaling box in the prior art cannot filter and recycle the cleaning liquid during descaling, resulting in a large waste of cleaning liquid, and the cost of cleaning and descaling the steam turbine rotor is relatively high. Therefore, we propose a A kind of steam turbine rotor descaling box and its descaling method are used to solve the above problems
