Introduction: MRH-3 high-speed ring block wear tester is mainly used in the form of sliding friction to evaluate the lubrication performance of various lubricants under the condition of oil-immersed lubrication. It is especially suitable for the simulation evaluation of scratch resistance of medium-to-high grade automobile gear oils. Can be used for a variety of metal, non-metallic materials and coating wear properties. The MRH-3 high-speed ring block wear tester can measure friction, calculate friction coefficient, connect to a computer, record temperature-time curve, friction-time curve. The machine is equipped with a high-precision measuring device that can measure, measure, and record the computer screen display of the friction wear spots. Technical Parameters: Maximum test force: 3000N The maximum measured friction: 300N Friction accuracy: ±2% Test force control method: Stepping motor closed-loop control exerts test force Spindle speed range: 100 ~ 2000r/min (5000r/min) stepless adjustable Speed control accuracy: ±10r/min Test oil temperature range: room temperature ~ 100 °C Test time control range: 10～9999s(min) Standard Huai test ring size: φ49.22mm×13.06mm Standard Huai test block size: 12.32mm×19.05mm Dimensions: 1300mm×700mm×1340mm Total weight: 800kg
