[0002] Gear box is one of the core components of the fan, and its running condition directly determines the service life of the fan. According to statistics, the gear box failure is closely related to the quality of the gear box oil. Gear oil is the blood of the fan gear box. The gear box runs under complex working conditions for a long time, and the gear surface, bearing and other parts have pitting, fatigue spalling, wear and tear, etc. Metal particles are generated and mixed into the gear box oil. Therefore, oil monitoring is an effective means to diagnose the wear and tear and running condition of the fan gear box and to improve the safety and reliability of offshore wind power operation.

If the research of fan gear box oil quality online monitoring system is carried out, the online monitoring of key indicators can be realized, and the abnormal situation of fan gear oil can be found in time.

[0004] Fan gear oil filtration is an effective means to improve the gear box oil, especially the wear condition. The research of fan gear box oil online filtration technology can timely treat the abnormal gear box oil and avoid lubrication failure, thereby wearing the gear and bearing working surface, forming a vicious cycle between oil and parts, and shortening the service life of the gear.

Since the wear of gear and the change of gear oil are not linear changes, it is necessary to monitor the viscosity and content of particulate matter of gear oil in time, and then purify in time.

[0006] Therefore, the research on the online monitoring and filtering technology of the fan gear box oil is carried out, and the online monitoring and filtering treatment device is developed, so that the abnormal conditions of the fan gear box oil can be found in time, early warning and reasonable treatment measures can be taken, the wear and failure of the unit can be reduced, the reliability and safety of the equipment can be improved, the operation and maintenance cost of the whole life cycle of the equipment can be saved, the service life of the gear oil is prolonged, and the good lubrication environment of the gear box is ensured, so that the fan gear box has the high performance and health operation in the whole life.
