Oil change system of wind driven generator gearbox and leak-proof security protection method for oil chang

Abstract

The invention discloses an oil change system of a wind driven generator gearbox. The oil change system comprises a waste oil extraction system and a new oil filling system. A waste oil leak-proof security protection device is respectively arranged along the pipelines of a waste oil pipe and a new oil pipe. A leak-proof security protection method of the oil change system is composed of two steps, namely waste oil extraction and new oil transformation, and the specific steps are as follows: firstly, starting a waste oil transfer pump to pump the waste oil in the gearbox of the tower top of a wind driven generator into a waste oil tank through the waste oil pipe, and then starting a new oil transfer pump to fill the new oil in a new oil tank into the gearbox through the new oil pipe. The leak-proof security protection method provided by the invention cannot only reduce the possibility of an accident in the oil change process, but also can farthest prevent leakage under the circumstance of oil pipe damages to the maximum limit. The leak-proof security protection system is simple in structure and low in cost, and the leak-proof security protection method is easy to operate and excellent in performance, thereby being suitable for being used in oil change process for various wind driven generator gearboxes.

Description

technical field [0001] The invention relates to gear box oil change equipment and an oil change method, in particular to gear box oil change equipment and a leak-proof and safe oil change method located at high altitudes, which can be used for wind power generator gear box oil change. Background technique [0002] With the advancement of the sustainable development strategy, wind power technology has developed rapidly in recent years. But there are some problems in the maintenance of wind power generation equipment at present. After the gearbox of the wind turbine is used for a period of time, it will wear to a certain extent and affect the normal use of the lubricating oil in the gearbox. Therefore, people need to regularly replace the lubricating oil in the wind turbine gearbox. There are generally two types of oil change methods at present, one of which needs to use manpower to transfer the oil barrel by barrel to the gearbox at a height of 100 meters. It usually takes ...

AI Technical Summary

Problems solved by technology

Since the wind farms are all located in places with abundant wind resources, the oil change pipes are likely to shake greatly due to strong winds during the oil change process, and even cause bursting and falling off. When the oil pipes burst and fall off, there will be a large amount of oil leakage

If the oil change process takes place in the tower, the leaked oil will pollute the inner wall of the tower and the devices in the tower, and the cleaning cost is extremely expensive. What is more serious is that the oil spills on the converter working under high pressure in the tower , will damage the converter, and the loss is as high as hundreds of thousands to several million

If the oil change process is outside the tower, it is extremely dangerous for the oil change pipe weighing several hundred kilograms to fall rapidly from a height of 100 meters under the action of wind force, posing a considerable threat to people and objects within a range of 100 meters. , once it falls, the consequences will be unimaginable

And for offshore wind turbines, the leaked oil will pollute the marine environment, and the consequences are quite serious
