Digital ecology drives continuous lubrication of wind power gear system to build smart operation and maintenance deployment applications of clean energy

If there is an abnormal failure of the wind turbine equipment, it means that the maintenance costs are high and the delay costs gradually accumulate, which is due to the chain reaction triggered by small failures. In order to ensure the stable operation of wind farms, it is essential to strengthen active maintenance and avoid passive maintenance.

First, wind turbine lubrication characteristics

Wind power gearbox usually requires high performance industrial gear oil, commonly used lubricating oil ISO VG 320 is a high viscosity industrial gear oil, with extraordinary wear resistance, extreme pressure, oxidation resistance and anti-bubble properties, suitable for high load gear systems, can provide reliable lubrication protection, extend equipment life.

Second, the lubrication dilemma of wind turbines

During the operation of wind turbines, the lubricating oil experiences harsh working environments, including high-speed rotation, high temperature, high load and particle pollution. These factors can lead to lubricating oil failure, degradation and contamination, which affects the performance and life of the unit.

Especially in the key components such as the main gear box of the fan, the variable pitch system and the yaw device, the lubricating oil is vulnerable to serious thermal oxidation and mechanical shear due to its long-term high-speed operation and great mechanical stress. In addition, the lubricant will also adsorb and carry metal particles and other solid pollutants, accelerate oil pollution, increase unit friction and wear.

Third, wind turbine health lubrication prediction operation and maintenance program

Real-time monitoring and early warning of important gear systems such as wind power gearbox, generator and electric pump equipment are carried out to ensure the normal operation of equipment and extend the life of equipment.

1.0 Monitoring Process

Install the oil monitoring sensor to monitor the oil temperature, oil pressure, moisture content, viscosity and other parameters in the gear box. Through real-time data acquisition and transmission, the monitoring data is uploaded to the reliability platform.

The aging model of gear oil is established on the platform, and the monitoring data is used for real-time prediction to evaluate the life of the reducer.

Analyze the monitored data, detect oil emulsification, excessive viscosity, abnormal gear wear and other faults, and give graded alarm.

The platform supports access to all kinds of monitoring data, and provides data early warning functions on web and mobile terminals, so that operation and maintenance personnel can monitor equipment status at any time.
