油液分析技术能在机器不解体的情况下,从润滑油中获取有关机器运转状况的各种信息,现已在机械设备的状况监测和故障诊断技术领域中占有重要地位,其中以光谱分析技术和铁谱分析技术应用较广。光谱分析技术能对油液中各种金属元素含量作准确分析,但只能检测8μm以下的磨粒,而一般机械在异常工况下产生的磨粒主要是大于10μm的磨粒。铁谱 Oil analysis technology can obtain a variety of information about the operating conditions of a machine from the lubricating oil without disassembling the machine and is now an important part in the field of condition monitoring and fault diagnosis of machinery and equipment. Spectral analysis And iron spectrum analysis technology is widely used. Spectral analysis technology can accurately analyze the content of various metal elements in the oil, but can only detect abrasive particles below 8μm. However, the abrasive particles produced by the general machinery under abnormal conditions are mainly abrasive particles larger than 10μm. Iron spectrum
