摘要
齿轮箱是双馈式风电机最重要的部件之一,其运行稳定性对于风电机组的可靠运行至关重要,齿轮箱润滑和冷却系统性能对齿轮箱的使用寿命以及工作效率非常重要.良好的润滑和冷却系统不仅可以对齿轮箱内部的齿轮、轴承起保护作用,还能吸收冲击和振动,减少摩擦,防止齿轮点蚀和胶合.齿轮箱润滑油温度不仅可以检验风电机组运行负荷性能,也是衡量齿轮箱运行状态的重要参数.风电机组齿轮箱润滑油过热的问题不但影响机组出力,还会降低润滑油使用寿命,甚至导致齿轮箱发生严重损伤.针对此问题,提出对散热系统、温控阀及空气滤清器的改造方案,应用效果明显,可操作性强.
Gear box is one of the most important and valuable components of doubly-fed wind turbine.Its operation stability is very important for the reliable operation of wind turbine.The performance of lubrication and cooling system of gear box is very important for the service life and working efficiency.Good lubrication and cooling system can not only protect the gears and bearings inside the gear box,but also absorb shock and vibration,reduce friction and prevent pitting and gluing of gears.The temperature of the gear box lubricating oil is crucial to the influence of the chemical performance index of the lubricating oil.It not only tests the operation load performance of the wind turbine,but also is an important parameter to measure the operation state of the gear box.The overheating problem of gear box lubricating oil of wind turbine unit affects the unit output,reduces the service life of lubricating oil and even causes serious damage to the gear box.In view of this problem,though analysis and research,the transformation scheme of heat dissipation system,temperature control valve and air filter was put forward,which has obvious application effect and strong operability.
