Routine maintenance of wind turbine gearboxes
Oct 16, 2018

1. Regular maintenance and routine maintenance

1.1 Routine maintenance Daily maintenance of the wind turbine includes checking the appearance of the gearbox, electrical wiring, etc. The main tasks include: cleaning the appearance of the gearbox; checking the gearbox lubrication circuit for leaks, loosening the pipe connection; whether the oil drain valve at the bottom of the gearbox is loose or infiltrated; check the oil level, oil color and Is the oil mark normal? If the color of the oil turns black and is still deep, you should replace the new oil in time. Check the vibration and noise conditions of the gearbox while the unit is running. If the filter is clogged and an alarm is caused, it is necessary to find the cause of the fault in time. If necessary, replace the filter element and observe whether the oil color and impurities are normal. When installing the outer casing of the filter, pay attention to the active thread and the force should be even to avoid damage to the thread. Check that the radiator of the gearbox is clogged, can be cleaned by reverse cooling, or cleaned with a brush. After the above inspections are performed, the oil level, temperature, pressure and observation window of the gearbox are compared. Check for worn wires, and identify potential hazards in time and eliminate them in advance. In addition to the above checks, there are some faults in routine maintenance.

1.2 Regular maintenance and maintenance Regular maintenance of wind turbines mainly includes: checking the torque of the gearbox connecting bolts, checking the gear meshing and tooth surface wear, tightening the wiring screws of each sensor, and checking the heat dissipation performance, checking the gear box and motor In the case of alignment, the vibration and noise of the gearbox are detected. Test and analysis of gear oils to better understand the working condition of the gearbox. According to the wind turbine operation and maintenance manual, the gear oil used by different manufacturers is different. It is generally required to sample the oil every year or two years. If there is an abnormality in the operating state of the gearbox, it is necessary to collect the oil sample at any time. The service life of gear oil is generally three to five years, and the replacement of gear oil is generally limited to time. Because of the operating environment of the gearbox, it is not necessary to ensure the economical and safe operation of the gearbox in different operating environments. This requires the operator to pay attention to collecting and sorting the data of the wind turbine, and comparing the test results of the oil parameters. Analyze and find out more compatible with the replacement cycle of your own power plant. Avoid oil level too high when refueling, causing the oil seal at the input shaft end to leak.
