The MVF-1 A type friction and wear testing machine produced by the company is a friction form with rolling, sliding or sliding composite movement under a certain contact pressure, with a stepless speed regulation system, which can be used at very low speed or Under high-speed conditions, it is used to evaluate the friction and wear performance of lubricants, metals, plastics, coatings, rubber, ceramics and other materials, such as the friction function of low-speed pin discs (with large and small plates, single needles and three needles), the anti-wear performance of four balls and the fatigue of four-ball rolling contact, the lubrication performance of ball-bronze three pieces, and the test of thrust washer, ball-plate, mud wear, lip sealing torque and stick-slip friction performance of rubber sealing rings. The matching reciprocating module enables reciprocating frictional wear movements. The testing machine has a wide range of application prospects in various professional and technical fields of tribology, petrochemical, machinery, energy, metallurgy, aerospace, colleges and universities, research institutes (institutes) and other departments.
