Description

Technical Field

[0001] This utility model relates to the field of oil detection technology, and in particular to a sampling device for oil monitoring systems in mining equipment. Background Technology

[0002] Oil quality testing refers to determining the quality of oil within a container. An online oil quality testing system takes samples from the oil tank's return line and, through a testing module, monitors the physicochemical properties of the lubrication station's return oil in real time, analyzing various oil parameters. When abnormal parameters are detected, early wear and foreign object intrusion can be identified promptly, enabling predictive maintenance of critical components such as sliding bearings, predicting the remaining life of the lubricating oil, and preventing major equipment accidents.

[0003] A sampling device for intelligent oil detection is disclosed in Chinese Patent Publication No. CN213422682U. This intelligent oil detection sampling device enters the oil through the external threaded post at the lower end opening of the sampling tube, so that the oil enters the interior of the sampling tube from the lower end opening of the sampling tube, thereby realizing the sampling of oil at different heights. Then, the sampling tube is rotated so that the sliding cover closes the lower end opening of the sampling tube.

[0004] However, compared with existing technologies in related fields, when oil samples need to be collected from different locations according to actual working conditions, oil residues will remain inside the sampling tube, causing oil at different depths to mix, which will affect the oil detection results and cause detection errors.
