各类机械流体系统工作的可靠性和机件的寿命,在很大程度上取决于油液的污染程度。据有关统计资料表明,仅液压系统的故障就有75％左右是由于受到污染而造成的。因此,对流体系统进行监测和诊断,使故障在发生之前就作出预报并及时处理,就成为故障诊断技术的重要研究内容之一。根据油液中污染的元素成分、数量、尺寸、形态等物理化学性质,对其污染性故障进行预防性监测诊断,称为污染诊断技术。本讲就其原
The reliability of all types of mechanical fluid systems and the life of mechanical parts, to a large extent depends on the degree of oil pollution. According to statistics, only about 75% of hydraulic system failures are due to contamination. Therefore, it is one of the important research topics for fault diagnosis technology to monitor and diagnose the fluid system so that the fault can be predicted and dealt with in time. According to the contaminated elements in the oil composition, quantity, size, morphology and other physical and chemical properties of its pollution-based preventive monitoring and diagnosis of pollution, known as pollution diagnosis.
