摘要
液压油液污染是液压系统发生故障的主要原因,其污染途径有潜在污染、侵入污染和新生污染,可采取减少外来污染、滤除杂质、控制液压油液的工作温度、定期检查更换液压油液来降低液压油液的污染程度,进而提高液压传动系统的可靠性。
The treatise illustrates the necessity of controlling hydraulic system pollution according to the survey of hydraulic machine failure, points out the sources and hazards of hydraulic system pollution and delivers the methods of controlling hydraulic system pollution, pollution standards and criteria of renewing hydraulic oil. It has a certain referential value in prolonging the lifespan of each hydraulic machine and improving the enterprise economic profits.
