Cleaning method of gearbox of wind-driven generator

Abstract

The invention discloses a cleaning method of the gearbox of a wind-driven generator. The method comprises the steps of old oil discharging, washing, circulated washing, cleaning and circulated cleaning. According to the cleaning method of the gearbox of the wind-driven generator, firstly, No.32 oil with high liquidity and low viscosity serves as the washing oil to wash the inside of the gearbox at high pressure, and also, single-component surfactant and disperse additives can be added inside the washing oil to achieve better washing effects; secondly, the washing oil is circulated and filtered to eliminate particle residues at the bottom of the gearbox, oil residues on the walls, oil dirt and the like and further can deeply reach the dead ends inside the gearbox, where common cleaning manners cannot reach; thirdly, No.320 lubricating oil for normal operation of the gearbox serves as cleaning oil to washing the inside of the gearbox at high pressure, and then the cleaning oil is circulated and filtered to be fully fused with residue waste oil and diluted. Therefore, the waste oil residue rate can be greatly reduced, and further the cleaning effects can be greatly improved.

Description

technical field [0001] The invention relates to a cleaning method for a gear box of a wind power generator. Background technique [0002] As the installed capacity of wind turbines in my country exceeded 60,000 units at the end of last year, more and more wind turbines began to enter the oil change cycle. According to the requirements of gearbox manufacturers and lubricating oil manufacturers, in order to prolong the life of the gearbox and reduce the frequency of oil change, the gearbox must be cleaned before oil change to remove the sludge, oil and metal particles in the gearbox to ensure the replacement The cleanliness of the incoming oil reaches the standard. Especially in the case of changing the oil brand and type, if the residual oil in the gearbox is not completely removed, it will bring serious consequences, that is, the mixing of different brands of lubricating oil will make the wind turbine generator There are abnormal sounds and speeding phenomena. The existin...

AI Technical Summary

Problems solved by technology

Due to the limitation of the structure of the gearbox, that is, there is a certain distance between the oil discharge port of the gearbox and the bottom of the gearbox body, and the 320 lubricating oil used has the characteristics of high viscosity and poor fluidity, so that the sludge and oil in the box cannot be removed. The cleaning is clean, and the residual oil is not completely discharged, that is, the residual rate of old oil in the gearbox is relatively high

The simple cleaning method currently used is also difficult to meet the cleanliness requirements of the gearbox. This phenomenon has become a major problem in the maintenance of wind turbines
