I.Overview

The lubricant anti-wear tester is in the form of sliding friction and is mainly used to evaluate the bearing capacity of lubricants under extremely high point contact pressure conditions. Including the maximum non-seizure load Pb, sintering load Pd, comprehensive wear value ZMZ and other three indicators, in practical applications, different evaluation indicators can be selected according to various uses of the lubricant. The four-ball friction tester can also do long-term anti-wear test of lubricants, measure friction coefficient, record friction force and temperature curve. Using special accessories, it is also possible to carry out simulation tests of end wear and materials. The design principle of the machine is based on the loading stability of the lever four-ball machine, combined with the loading characteristics of the servo valve, through the servo motor, air spring, closed-loop control software to achieve automatic reset, automatic loading, automatic maintenance, automatic test, automatic unloading, automatic Measure the diameter of the wear spot and take a picture, one-key operation, one-key data storage, fast test speed, minimal error, good repeatability, no pollution, no noise, and high efficiency.
