Wind generator gear lubricating oil on-site regeneration treatment system and method

Abstract

The invention relates to a wind generator gear lubricating oil on-site regeneration treatment system and method. The system includes a vacuum dehydration system, a regeneration system, a filtration system, a heating system, an additive automatic replenishing system, an oil quality on-line monitoring system, a cleaning and filling system, a magnetic filtration system, a circulating oil pump and an oil suction valve. Waste oil is sucked into a vacuum tank of the vacuum dehydration system, the circulating oil pump pumps the oil out from the bottom of the vacuum tank, after passing through the heating system, the magnetic filtration system, the regeneration system and the filtration system, the treated oil is returned to the vacuum tank from the vacuum tank top. The on-line monitoring system monitors the oil product parameters in real time during regeneration, after removal of degradation products from the oil product, an additive is added according to the index parameters of recovered oil, the cleaning and filling system performs repeated flushing on a waste oil drum and loads the qualified oil obtained by regeneration treatment into the cleaned oil drum. The replaced waste gear oil is subjected to regeneration treatment and on-line quality monitoring on site, thus ensuring that the oil subjected to regeneration treatment meets the standard requirements.

Description

technical field [0001] The invention belongs to the technical field of on-site regeneration treatment of wind power generator gear lubricating oil, and in particular relates to a system and method for on-site regeneration treatment of wind power generator gear lubricating oil. Background technique [0002] In recent years, my country's wind power generation units have been increasing year by year, with a total of about 100,000 units. While the number is increasing, the capacity of the units is also increasing, and the amount of lubricating oil required is also increasing. The oil consumption of gear lubricating oil in the wind turbine gearbox is about 300-600L, accounting for 3 / 4 of the oil consumption of the entire unit, and it is a crucial link in the wind turbine. [0003] Wind turbine gear lubricant plays a key role in ensuring the performance of the gearbox. The gear oil not only has the effect of lubricating and heat dissipation during the operation and transmission o...

Problems solved by technology

[0004] Since wind turbines are mostly installed in remote, open, and windy areas, such as Xinjiang, Inner Mongolia, Gansu, and coastal areas in China, the working environment of the gearbox has large temperature changes, high coastal humidity, and large torsion loads and loads. The instability of the gear lubricating oil is more prone to deterioration during operation

The downtime of wind turbines caused by gearbox oil quality problems is the main reason affecting the running time of wind turbines. The increase in operation and maintenance costs and the huge losses caused by frequent accidents have seriously affected the economic benefits of the wind power industry.

At present, at home and abroad, the deteriorated waste gear oil is usually replaced with new oil. This method will not only incur huge costs, but also easily cause environmental pollution and other impacts during the replacement and transportation process.
