摘要
长期以来,液压操动机构中油液污染成为电网可靠运行的隐患之一。笔者介绍了液压操动机构中油液的颗粒污染度等级国家标准及有关国际标准,对液压系统颗粒污染产生的原因和危害进行了分析,对机构中进行磨削加工或者是采用磁检验后零部件的消磁进行了介绍,提出了液压操动机构的液压系统对油液的清洁度要求及污染防治方法。实验结果表明,这些措施是必要而有效的。
Oil pollution in hydraulic operating mechanism is hazardous to reliable operation of power grid. This paper introduces particle pollution degrees in Chinese national standards and corresponding international standards, analyzes the source of particle pollution and the harm, and discusses the grind-machining and the demagnetizing methods of the mechanism's parts after magnetic inspection. Moreover, requirement of oil cleanliness and particle pollution control methods for hydraulic system of hydraulic operating mechanism are proposed. Experimental result shows the methods are effective.
