Mmu - 5 G Vacuum High Temperature Friction and Wear Tester

One, the main function
High temperature friction and wear tester under certain contact pressure, with high temperature and normal temperature, atmosphere protection under the state of the rolling, sliding or complex movement form of friction roller has stepless speed regulation system, can be in extremely low speed or high speed condition, used to assess lubricant, metal, plastic, coating, rubber, ceramics and so on friction and wear properties of materials. The machine has a lot of friction pair expand the space, such as low speed pin plate (with the market and the small dish, with three single needle) friction function, four ball long four ball rolling contact fatigue and wear resistance and the ball - bronze three-piece lubrication performance, as well as the thrust washer, ball - plate, slurry abrasion, and stick-slip friction performance test
Second, the control method and software function
High temperature precision test instrument for mechanical and electrical integration of liquid friction and wear testing machine. Imported hydraulic pump as power source, the overflow, throttle, directional valve are Taiwan original and independent of the proportional valve and hydraulic cylinder with frictionless piston cylinders, guarantee the accuracy of the force value. Integration of spindle motor selection teco servo speed control system and motor, speed stability, large torque, wide speed range, low noise. Measuring parameters include test force, friction force, test time, test cycle (spindle revolutions). For four parameters according to the preset material research, in order to achieve the best use effect, when any one parameter exceeds the preset value, the corresponding alarm lights, spindle stop running at the same time. All measured axis can be real-time display on the computer screen, record test curve at the same time, and save the test curve.
