摘要: 近年来,设备在运转过程中发生轴承温度突然上升、滑阀卡涩等故障的次数越来越多,但在拆检过程中并没有发现较大的设备问题,而只是发现了一些结焦物、积碳等。经过简单清理、投入运转一段时间后,又会再次发生同样的故障。针对此类问题进行研究,分析出导致故障的原因为漆膜。文章阐述了漆膜形成的原理、漆膜的危害以及润滑油检测项目,介绍了目前常用的几种除漆膜设备,同时,结合两个除漆膜设备的应用实例,对比分析了其投用前后的数据,结果显示,除漆膜设备的应用降低了漆膜倾向指数。此外,常规润滑油检测无法满足当前的生产要求,需要根据润滑油实际应用场景制定针对性检测项目。

Abstract: In recent years, the number of failures such as sudden rise of bearing temperature and jamming of slide valve occurred during the operation of the equipment has been increasing. However, during the disassembly and inspection process, no major equipment problems were found and only some coking materials and carbon laydown were found. After simple cleaning and putting into operation for some time, the same failure would occur again. The problem was studied and the cause of the failure was found to be varnish. This paper expounds the formation principles of varnish, the hazards of varnish, and lubricating oil detection. It introduces several commonly used equipment for varnish removal. At the same time, it compares and analyzes the data before and after the practical application of two varnish removal equipment. The results show that the application of varnish removal equipment reduces the MPC. In addition, conventional lubricating oil detection cannot meet current production requirements, and targeted detection programs need to be developed based on actual lubricating oil application scenarios.

Key words: varnish, MPC, lubricating oil detection
