The testing machine can monitor the changes in friction force and the wear condition of the sample surface in real time during the test, and also precisely control and monitor various parameters of the testing machine in real time.
Application
The sliding bearing PV friction testing machine is primarily used to evaluate the friction and wear performance of engineering plastics, powder metallurgy materials, alloy bearings, and other materials under sliding friction conditions. By simulating different friction conditions, such as variations in load, speed, time, friction pair materials, surface roughness, and hardness, this testing machine can determine the PV value (the product of pressure and velocity, used to represent the load-carrying capacity of sliding bearings), as well as the optimal clearance and lubrication medium.
Standard
GB 7948-1987:Test method for PV limit of plastics bearings

Test Procedures
Sample Preparation: Load the sliding bearing sample to be tested onto the test rig, ensuring its surface is clean and smooth.
Load Application: Apply a specific force or pressure to the sample surface using the loading system, simulating the load conditions under real working conditions.
Start of Test: Start the test machine control system, controlling the movement speed of the test rig and the load changes according to preset conditions, and begin simulating the friction and wear process.
Data Acquisition and Analysis: Collect and record data such as friction force, load changes, and sample surface morphology in real time, and perform analysis and comparison to evaluate the friction performance and wear resistance of the sliding bearing.
