MRH-3 High Speed Ring-Block Wear Testing Machine
1. Usage
MRH-3 high speed ring-block wear testing machine is mainly applied for performance evaluation of all kinds of lubricants, especially for the simulating evaluation for scratch resistance performance of gear oil of high-grade vehicles. It can also be used for performance study of anti-friction capacity of aviation kerosene and capacities of all sorts of paint coating, metal and non-metal materials. This machine can determine moment of friction, calculate coefficient of friction. It can finish data processing, drawing temperature time curves and friction moment-time curves, recording and printing test data. The test data can also be saved.
