Embodiment Construction

[0018] The present invention is based on the evaluation method of lubricating oil wear resistance on-line monitoring of ball-on-disk wear, which monitors the concentration of abrasive grains in the lubricating oil when the ball-on-disk friction pair of a pin-on-disc wear machine is in a boundary lubrication state in real time through an online image visual ferrography instrument. , to evaluate the anti-wear properties of lubricating oils. It includes the following specific steps:

[0019] 1) Supply oil to the ball-disk friction pair according to the set flow rate, and start the online image visual ferrography at regular intervals to sample and deposit the lubricating oil flowing through the ball-disk friction pair, and obtain wear particle deposition from the online image visual ferrography Picture; at the same time, the oil circuit of the online image visual ferrography instrument is flushed, and the oil supply to the ball-disk friction pair is equal to the sum of the samplin...

Abstract

The invention discloses a method for evaluating abrasion resistance of lubricating oil based on ball disc abrasion online monitoring and a device. The method comprises the following steps of: monitoring the concentration of abrasive particles in the lubricating oil when a ball disc friction pair of a pin disc abrasion machine is in a boundary lubrication state in real time and on line through an online image visual ferrograph, and evaluating the abrasion resistance of the lubricating oil. The method can be used for monitoring the abrasion resistance of the lubricating oil in real time when the friction pair is in different abrasion states. The device for implementing the method is simple in structure, convenient to operate and easy to implement.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil wear resistance testing, and relates to a lubricating oil wear resistance evaluation method, in particular to a lubricating oil wear resistance evaluation method based on online monitoring of a ball-on-disk wear test. Background technique [0002] Reducing wear is the most important and basic performance of lubricating oil. At present, there are many standard methods for testing the wear resistance of lubricating oil at home and abroad, such as the four-ball machine method, Timken method and Falex method. The domestic standard methods are SH / T0189, GB / T 11144 and SH / T 0188 respectively. Standard methods are ASTM D4172, ASTM D2782, ASTM D2670. However, these standard methods all use the final wear result as an index to evaluate the anti-wear performance of lubricating oil, which cannot reflect the anti-friction characteristics of lubricating oil during the wear process. [0003] Using the...
