Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] Such as figure 1 Shown is a flow chart of the method for removing impurities in lubricating oil samples in the oil monitoring spectrum analysis of mining equipment of the present invention, including:

[0019] Step S101, using a water removal device to heat the lubricating oil sample, so that the water in the lubricating oil sample evaporates, and collect the evaporated lubricating oil sample;

[0020] Step S102, drop the evaporated lubricating oil sample onto the substrate in the device for removing non-metallic impurities, remove non-metallic impurities from the evaporated lubricating oil sample on the substrate, and obtain a substrate with adsorbed metal particles;

[0021] Step S103, cleaning the substrate on which the metal particles are adsorbed with a cleaning solution to obtain a liquid sample containing metal particle...

Abstract

The invention discloses a removal method and an analysis method of impurities in a lubricating oil sample in mining device oil fluid monitoring spectral analysis. The removal method comprises the following steps: heating the lubricating oil sample through adopting a water removal device to evaporate water in the lubricating oil sample, and collecting the evaporated lubricating oil sample; adding the evaporated lubricating oil sample to a substrate in a nonmetal impurity removal device in a dropwise manner, and carrying out nonmetal impurity removal on the evaporated lubricating oil sample on the substrate to obtain a substrate adsorbed with metal particles; and cleaning the substrate adsorbed with the metal particles to obtain a metal particle-containing liquid sample used for spectral detection. The removal method and an analysis method of impurities in the lubricating oil sample in mining device oil fluid monitoring spectral analysis solves interference of impurity elements in the spectral analysis to a detection result, and also avoids interference of water in the lubricating oil sample to the spectral analysis result and process.

Description

technical field [0001] The present invention relates to the related technical field of mining equipment oil monitoring spectrum analysis, in particular to a method for removing impurities in lubricating oil samples and an analysis method in mining equipment oil monitoring spectrum analysis. Background technique [0002] In recent years, the intensification and leanness of the coal mining process have received increasing attention. Among them, monitoring the operation status of coal mining equipment, forecasting potential failures and taking timely measures can significantly reduce the frequency of equipment failures and maintenance costs, and prolong the service life of equipment. Among them, the oil monitoring of equipment lubricating oil is one of the most important technical means. The oil monitoring system is composed of ferrographic technology, spectral technology, conventional physical and chemical analysis, pollution degree analysis and other technologies. Among them,...
