Monitoring method of large particle metal abrasive dust in machine lubrication system

Abstract

The invention discloses a monitoring method of large particle metal abrasive dusts in a machine lubrication system. The method is realized by using a machine lubrication oil filter element abrasive dust detection device and an energy chromatic dispersion X-ray fluorescence spectrometer, and the method comprises the following steps: an abrasive dust membrane with large particle metal abrasive dusts is manufactured by using the machine lubrication oil filter element abrasive dust detection device; the chemical components and mass distribution of the large particle metal abrasive dusts on the abrasive dust membrane are analyzed by use of the energy chromatic dispersion X-ray fluorescence spectrometer, so as to obtain X-ray fluorescence spectrum data; and a monitoring threshold value of the large particle metal abrasive dusts is set according to the X-ray fluorescence spectrum data, and the monitoring threshold value is revised along increase of the X-ray fluorescence spectrum data dynamically. According to the invention, chemical components, mass distribution and change trend of the large particle metal abrasive dusts can be monitored, and accordingly the monitoring threshold value can be set so as to monitor the large particle metal abrasive dusts in the machine lubrication system and improve the ability in forecasting abnormal machine abrasion faults.

Description

technical field [0001] The invention relates to a method for monitoring large-grain metal wear debris in a machine lubrication system, in particular to a method for monitoring large-grain metal wear debris in a machine lubrication system that obtains a monitoring limit value based on the chemical composition and mass distribution of large-grain metal wear debris and their changing trends. The invention discloses a chip monitoring method, which belongs to the technical field of equipment wear state monitoring. Background technique [0002] At present, lubricating oil atomic emission spectrometry analysis technology is mainly used at home and abroad to monitor the wear and tear faults of machines. However, the atomic emission spectrometer can only measure the metal wear debris suspended in the oil less than 10 microns; and the large metal wear debris larger than 25 microns in the oil is intercepted by the filter installed in the machine lubrication system. The large-particle ...
