摘要
采用控制变量法探究了影响润滑油中颗粒度的因素,分析了油样暴露在空气中的时间、油样温度、静置时间及系统压力等条件对颗粒度测试结果的影响.结果表明:油样在空气中暴露时间越长,颗粒度越多,油样污染越严重;控制单一变量,随着温度、压力及静置时间的增加,颗粒度测试结果增大到一定程度后趋于稳定.油品颗粒度检测对于保护发电机组、预测故障、评估油品的污染程度以及提高发动机性能和经济性都具有重要的意义.
Abstract
This study employs a controlled variable method to explore factors influencing the particle size of lubricating oil.By comparing the effects of exposure time of oil samples to air,oil sample temperature,settling time,and system pressure on particle size test results,it was found that the longer the oil sample was exposed to air,the greater the number of parti-cles and the more severe the oil sample contamination.Controlling a single variable,as temperature,pressure,and settling time increase,the particle size test results initially rise to a certain level before stabilizing.Monitoring particle size in lubrica-ting oil is crucial for protecting generator units,predicting faults,assessing oil contamination levels,and improving engine performance and economical efficiency.
