众所周知，齿轮箱润滑油对于风电齿轮箱而言，就像血液于人体一样重要，油液的状态直接关系到齿轮箱的健康。今天就威能极在油液检验方面的一些经验与大家进行交流。
若要了解如何给润滑油做体检，首先需要知道润滑油的作用和对润滑油的性能要求。润滑油在齿轮箱中起到了润滑、清洁、冷却等作用。不同规格型号润滑油的特性各异，针对于风电主齿轮箱而言，高稳定性、高承载能力、长寿命等是基本的要求。为使润滑油的性能达到风电齿轮箱润滑油的标准，需要向基础矿物油中添加特定的化学合成剂。常见的性能要求有抗氧化性、消泡能力和摩擦改善能力。这就意味着一次合格的齿轮箱润滑油检测过程，不仅仅是针对原油的，同时需要检测它的化学添加剂和性能参数。下面与大家具体分享检测的内容。
01 黏度
风电主齿轮箱的常见黏度为VG320，根据ISO 3448标准，在40℃情况下运动黏度在288~352mm²/s之间。黏度能够很好地体现润滑油的状态与寿命，如果黏度超出10%需要二次检验以确认检验准确性，再考虑是否更换润滑油。
02 添加剂
其常见的化学元素包括钙Ca、镁Mg、硼B、锌Zn、磷P、钼Mo、硫S等(添加剂成分与比重以润滑油生产商为准)
03 清洁度
根据 ISO 4406，润滑油清洁度不可低于 -/17/14。当清洁度超标后，我们需要进一步对污染源进行判断
04 污染物
油液被异物侵入
除了上述硬性的指标外，我们在做油液检测的时候，在关注绝对数值的同时，更要关注数值的变化趋势。因为油液检测数值的异常变化，往往反映出齿轮箱内部状态的变化。比如说在为期半年的检测结果对比中，发现了铁和铜的颗粒异常升高，就预示着齿轮箱内部某个轴承可能存在过度的磨损或损伤，需要进行主动检查或维修。
弗兰德公司（旗下拥有工业品牌弗兰德+风电品牌威能极）作为齿轮箱制造行业翘楚，常年与油液制造商、油液分析实验室合作，针对油液的性能和参数进行大量的实验分析，致力于在高品质润滑油的作用下，使齿轮箱获得更好的运行可靠性和更优异的传动效率。
