Main uses
microcomputer control fixed-speed friction tester is mainly used to measure the friction coefficient and wear rate of automobile brake linings (brake pads), automobile clutch facings, oil drilling rig brake blocks and a variety of industrial machinery friction pads, motorcycle brake pads and other non-metallic friction materials.
Performance Characteristics
Strictly in accordance with the provisions of the GB5763-98 standard, in keeping with the basic principles and structure of Japan's HP-S-type prototype machine based on the combination of modern technology to improve the design and become.
1 electromechanical integration of the whole structure, the user wiring available.
2 force measuring organization force flow in the same plane, completely solve the mechanical vibration problem.
3 gravity code calibration device, so that the measurement is more accurate.
4 stainless steel heating and cooling cover, wet parts of all nickel-plated rust-proof treatment, stainless steel nickel wire heater;
5 pre-furnace assay electric furnace precision casting friction disk.
9 increased cooling fan to prevent water vapor sprayed onto the surface of the friction disk and affect the measurement data.
10 adopted a new way of measuring force, canceled the vibration damping device, improve the measurement accuracy.
11 host and console compact structure, beautiful appearance, can realize the automatic circulation of cold water and drainage.
