Background technique

As the lubricating medium of mechanical equipment, the information carried by lubricating oil can reflect the operating condition and lubrication environment of the equipment. Therefore, the detection and analysis of various indicators of lubricating oil will help to gain an in-depth understanding of the operating conditions of the equipment, detect potential faults in time, and reduce risks. In the process of offline detection of oil samples, a number of pre-treatments are required to be performed on the oil samples according to the detection requirements, such as heating, shaking, and ultrasonic vibration. The quality of the pretreatment work directly affects the analysis results of the oil sample. If the oil sample is not shaken well enough and the bottom of the bottle is still attached, it will affect the pollution degree of the oil sample, ferrography test, PQ value and other indicators. Therefore, the pretreatment process of oil sample analysis is also very important.
