一. Main uses
The current-carrying friction and wear testing machine is specially designed to simulate and evaluate the friction and wear behavior of friction pairs under the condition of current passing. The testing machine can carry out friction and wear test under the condition of high speed and high current, and can set the test force, test speed and test current. Real-time measurement of friction and wear.
二. the main technical parameters
1, the maximum axial test force :1000N(automatic loading), accuracy ≤±1%
2, the maximum friction torque :2Nm, relative error ±2%
3, speed :1-3000 RPM, accuracy ≤±1%
4, wear measurement
4.1 Displacement sensor measuring range 0-10mm
4.2 Measurement accuracy of displacement sensor is 0.001mm
5, the sample current 0-100A, voltage 12V
6, friction pairs: large pin disc friction pairs, large ball disc friction pairs, small thrust ring friction pairs, four ball friction pairs and other friction pairs, can achieve points, lines, surfaces and other forms of friction, simulation of rolling, sliding, rolling and sliding composite motion and environment, temperature, media and other conditions of friction and wear test.
7, test medium: air, oil, water, mud, abrasive, etc.
8, heater heating range: room temperature ~ 200℃, accuracy: ±2℃.
9, testing machine control: Embedded computer is used to control the whole process of the testing machine, the supporting measurement and control software is used, the interface is visualized, the test conditions can be controlled in real time, the test parameters can be set in real time, the test data and the test curve can be collected in real time, easy to save and easy to handle. Automatically record friction - time curve, friction coefficient - time curve, temperature - time curve, test force - time curve, speed - time curve, etc.
