Which is a good fully automatic vacuum friction testing machine

Overview

　　High vacuum friction and wear testing machineMainly used to determine the solid lubrication of materials under different loads in high vacuum environments, as well as the friction and wear properties of other materials. It can achieve servo loading of vacuum pin discs, vacuum ball discs, and loads, and realize large-span high-precision detection from low load to high load. The vacuum degree can reach 10-7Torr.

　　High vacuum friction and wear testing machineThe vacuum system consists of a dual injection system. This professional pump controller is a solid-state inverter driven by a microcontroller. This controller can not only automatically drive the cooling fan of the pump, but also drive the exhaust valve.

Testing machine parameters

test system

Load range: 0.1N-200kN, macroscopic mechanical property testing of metals, ceramic materials, and lubricating oils

Rotating speed of ball sales disc: cw: 0.1rpm – 300rpm ccw: 0.001-50rpm

loading mode

Multiple force application modes: constant force mode, linear incremental mode, dynamic loading mode, etc.

By using a servo mechanical system for dynamic loading, this loading method can not only achieve dynamic constant force loading on surfaces, but also effectively eliminate errors caused by loading at high speeds. And dynamic loading was used to test the same area several times, resulting in curves with good repeatability.

parameter measurement

In situ detection: Real time monitoring and recording of multiple experimental data information such as friction force, friction coefficient, load, torque, critical load, surface contact resistance, capacitance, surface acoustic waves, wear amount, vacuum degree, etc., equipped with corresponding software, can directly visualize the experimental data for easy observation.

technical indicators

Vacuum degree 10-6 Torr, 10-7 Torr (optional)
