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
(1)GB 7948-1987:Test method for PV limit of plastics bearings
(2)JB/T 7381-2010:Powder metallurgy oil-retaining bearings - Determination of PV value
Working conditions
(1)The tester works normally under the following conditions:
(2)Within the range of room temperature 10℃～35℃.
(3) In an environment where the relative humidity is not greater than 80%.
(4) no vibration around, no corrosive media and no strong electromagnetic interference in the environment;.
(5) The fluctuation range of power supply voltage should not exceed ±10% of the rated voltage, and the fluctuation of frequency should not exceed 2% of the rated frequency; and
(6) Correctly installed on a firm foundation with a levelness of 0.2/1000.
Feature
(1)High-precision testing: Ensures the accuracy of test results through precise control and real-time monitoring.
(2)Wide range of applications: Suitable for various fields, including automotive manufacturing, aerospace, and mechanical engineering.
(3)Multifunctionality: Capable of performing tests under different lubrication and load conditions.
(4)Data processing: Test data can be displayed in real time, and corresponding data curves can be plotted for easy analysis and storage.
(5)User-friendly: The equipment is easy to operate, making it suitable for use in research institutions, universities, and research institutes.
