Abstract
Description
Technical Field
[0001] This invention relates to the field of lubricating oil testing technology, specifically to a device and method for detecting impurities in automotive lubricating oil. Background Technology
[0002] Lubricating oil plays a vital role in maintaining the normal operation of a vehicle engine. If the lubricating oil contains impurities, it may cause wear and tear on engine parts, or even clog the oil filter, leading to vehicle malfunctions. If the impurities in the lubricant reach a certain level, it may even cause damage to the vehicle.
[0003] In existing technologies, the quality testing standards for lubricating oil mainly focus on detecting the content of mechanical impurities and the viscosity of the lubricating oil. However, during the testing process, the uneven distribution of impurities in the lubricating oil samples can lead to errors in the quality test results of the samples due to the different impurities in each group of samples.
[0004] A portable lubricating oil testing device, disclosed in CN117451971A, uses a feeder to evenly distribute lubricating oil onto a uniform distribution pan, which then guides the oil to a guide ring, achieving stratification and more even distribution of the lubricating oil into the sample container. The rotating distribution pan then flings the stratified lubricating oil onto the inner wall of the sample container, further distributing impurities more evenly within the oil. Simultaneously, the treated lubricating oil falls evenly along the inner wall of the sample container, reducing air bubble formation and improving the accuracy of the test data. Spikes on the guide pin puncture some air bubbles in the lubricating oil during the feeding stage, and the gap between the guide pin and the rotating shaft allows the lubricating oil to fall along the surface of the rotating shaft into the distribution pan, preventing the formation of new air bubbles during the descent and further minimizing their impact on the test results. However, this method makes it inconvenient to clean the distribution pan after testing a set of lubricating oil samples. Residual lubricating oil may remain on the pan during subsequent tests, affecting the test results. Summary of the Invention

[0014] A method for detecting impurities in automotive lubricating oil using a testing device includes the following steps: First, a first motor drives a threaded rod to rotate, which in turn drives a threaded block to move up and down, thereby driving a connecting plate to move up and down. The connecting plate then drives a stirring rod to move up and down. A second motor drives the stirring rod to rotate, thereby agitating the lubricating oil in the oil cylinder. Small air bubbles in the lubricating oil are punctured by a sharp point. An electric push rod is then activated, which drives a moving block to move. The moving block drives a third pulley to move, tightening the transmission belt. This, in turn, drives the first pulley to rotate via the threaded rod, coordinating with the second pulley, the transmission belt, and the third pulley to...
