一. Main uses and scope of use
The machine adopts the form of sliding friction, which can be tested under the conditions of dry friction, drop oil lubrication, dip oil lubrication and changing load, speed, time, friction material, surface roughness, hardness and other parameters. It can measure bearing temperature rise, friction factor, wear amount, PV value, etc.
The quality of electrical equipment, assembly quality and appearance quality of the machine meet the relevant provisions of GB/T2611.
