The invention relates to the technical field of wind generating set gear box use, in particular to a method for cleaning a wind generating set gear box and replacing gear oil.
Background
The oil consumption of gear oil in the gear box of the wind generating set accounts for 3/4 of the oil consumption of the wind generating set, and is the most main key lubricating point of the wind generating set. According to relevant data statistics, tooth surface abrasion, tooth surface occlusion scratch and micro pitting corrosion caused by oil quality problems in the operation of a fan, even gear box faults such as tooth clamping, tooth breaking and the like account for more than 60% of the faults of a wind turbine generator, so that the safe operation of the wind turbine generator is endangered by the deterioration and the deterioration of the oil quality, and the economic benefit of the wind turbine generator industry is seriously influenced.
The gear oil inevitably undergoes deterioration and deterioration after long-term operation, deterioration products such as oil sludge are easily generated and adhered to the gear and the gear box, and impurities generated by gear abrasion and impurities introduced by external pollution are also inevitably remained in the gear box. Therefore, in order to improve the running safety of the unit, the oil quality index is monitored regularly, gear oil which is degraded and deteriorated and does not meet the running requirement is replaced by new oil in time, and damage and failure of a gear box caused by the degradation and deterioration of the gear oil are avoided.
The distance between the fan gearbox and the ground is dozens of meters, most of materials, accessories, tools and the like required by the related work are lifted through the lifting hole at the tail part of the fan cabin, and the object is lifted from the bottom of the tower by using a lifting machine provided with the fan. The weight of the hoisted object should meet the hoisting weight of the hoisting machine, and the size of the hoisted object should not exceed the hoisting hole.

2) And (3) adding new oil: the original oil barrel (208L/barrel) of the new oil leaving the factory is too large to pass through the lifting hole, so that the new oil can not be directly lifted. The method comprises the steps of firstly transferring and sub-packaging new oil into small barrels (25L/barrel) from original oil barrels leaving a factory, then transporting the small barrels to a fan cabin from the ground one by one, manually holding the small oil barrels to align to an oil injection port of a gear box, and injecting the new oil into the gear box until the process of injecting the new oil into the gear box is completed.
