一. Main uses:
MPV-20B type PV friction testing machine, using cantilever beam structure, is mainly used to evaluate the friction and wear properties of engineering plastics, powder metallurgy, alloy bearings and other materials, determine the PV value and select a reasonable fit gap, lubricating medium, friction mate material, surface roughness and hardness.
The machine adopts the form of sliding friction, which can be tested under various conditions of oil free lubrication, oil drop lubrication and changing load, speed, time, friction material, surface roughness, hardness and other parameters, and can be used to measure bearing temperature rise, friction coefficient, wear amount, PV value and so on.
