Treatment method for analytical ferrograph ferrogram-making oil sample

Abstract

The invention discloses a treatment method for an analytical ferrograph ferrogram-making oil sample. The method comprises: firstly subjecting a collected oil sample to heating and oscillation to make abrasive particles suspend uniformly; detecting the content of iron in the oil sample, setting an oil sample abrasive particle concentration dilution ratio respectively according to the iron content, and adopting liquid paraffin as a concentration diluting solvent; employing a tetrachloroethylene organic solvent to dilute the oil sample viscosity, keeping the volume ratio at 3:1; subjecting the oil sample to ferrogram-making, and then subjecting the abrasive particles to monolayer deposition on a substrate, keeping the abrasive particle coverage within the range of 10%-30%, depositing ferromagnetic abrasive particles greater than 5 micrometers in the entrance region of a ferrogram, and arranging the abrasive particles in a chain along a magnetic line direction. The abrasive particles on the ferrogram are free of stacking phenomenon, and no residual oil trace is left on the ferrogram, thus facilitating clear observation of a ferroscope. The method provided by the invention determines and established an oil sample dilution ratio standard, and under the premise of ensuring the abrasive particle accuracy reflected by the ferrogram, enhances the ferrogram-making efficiency of an analytical ferrograph, and improves the accuracy of equipment diagnosis.

Description

technical field [0001] The invention relates to a processing method for spectroscopic oil samples produced by an analytical ferrography instrument. Background technique [0002] With the development of science and technology, ferrography technology has been widely used in my country's industry and has become one of the important monitoring and diagnosis technologies for mechanical equipment. Analytical ferrography makes ferrograms from the collected oil samples, and then observes and identifies the abrasive grains deposited on the ferrograms through a microscope, and obtains important wear information such as the morphology, size, composition, and concentration of the abrasive grains. Qualitative and quantitative analysis, so as to correctly judge the wear status of the monitored mechanical equipment. Usually, when analytical ferrography is used to produce spectra, the oil samples used for spectrum preparation need to be repeatedly diluted in concentration to obtain ferrogr...
