Benefits of technology

This innovation improves how well an electricity generating machine's rotor disk can withstand harsh environments such as rain or snow without getting damaged over time due to its use for power generation.

Problems solved by technology

The technical problem addressed by this patented technology relates to preventing damage caused by rust from occurring at different parts (braking disks) of an airborne power generator's rotor shaft when stored, transferred, installed, operated under severe environmental factors like rain water). This can lead to failure of components such as bearings and other critical equipment within the machine.

Embodiment Construction

[0014] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0015] An anti-corrosion protection method for a high-speed brake disc of a wind power generating set, the steps are as follows:

[0016] First of all, the high-speed brake disc 1 made of Q345D steel is subjected to surface cleaning treatment, especially the brake friction surface 2 of the high-speed brake disc 1. The surface cleaning treatment includes degreasing agent, rust remover, cleaning agent, dehydration degreasing, derusting, cleaning, and drying the high-speed brake discs in turn.

[0017] Then, the high-speed brake disc 1 in the above steps is subjected to an anti-corrosion treatment, the anti-corrosion treatment is to carry out a zinc-seeding treatment to the high-speed brake disc 1, and the zinc-seeding treatment is to process the high-speed brake disc 1, zinc powder and The inert medium is mixed and placed in a vacuum-sealed stainless st...

Abstract

The invention discloses an anticorrosion protection method for a high-speed braking disc of a wind generating set. The method comprises the following steps of: removing oil of the high-speed braking disc by sequentially utilizing an oil removing agent, a rust removing agent, a washing agent and a dehydrating agent; removing rust, washing, cleaning and drying; then, carrying out nano zinc powder zinc impregnation treatment on the high-speed braking disc; and performing phosphating treatment or chromic acid passivating treatment. By utilizing the method disclosed by the invention, zinc-iron alloy protection layers formed on a braking friction face and other surface of a high-speed braking disc base body have the advantages of abrasion resistance, corrosion resistance and high-temperature resistance.
