MZK-5 high temperature vacuum friction and wear testing machine

1. Main functions

MZK-5 High Temperature Vacuum Friction and Wear Testing Machine This machine has the friction form of rolling, sliding or sliding combined motion under abrasive, high temperature, normal temperature, atmosphere protection and other conditions under a certain contact pressure. It has a stepless speed regulation system and can be used to evaluate the friction and wear properties of lubricants, metals, plastics, coatings, rubber, ceramics and other materials under extremely low or high speed conditions.The machine has a large space for friction pair expansion, such as low-speed pin-disc (with large disc and small disc, single needle and three-pin) friction function, four-ball long-term wear resistance and four-ball rolling contact fatigue, ball-bronze three-piece lubrication performance, and testing of thrust washers, ball-disc, mud wear, and stick-slip friction performance

2. Control methods and software functions

The MZK-5 high temperature vacuum friction and wear testing machine is an electromechanical and hydraulic integrated precision testing instrument.An imported hydraulic pump is used as the power source. The overflow, throttling, and reversing valves are all proportional valves originally installed and independently developed in Taiwan. The hydraulic cylinder uses a frictionless plunger cylinder to ensure accurate force values.The spindle motor adopts servo integrated speed control system and motor, which has stable speed, large torque, wide speed range and low noise.Measurement parameters include test force, friction force, test time, and test cycle (number of spindle revolutions).The four parameters can be preset according to the material under study to achieve the best use effect. When any parameter exceeds the preset value, the corresponding alarm light will light up and the spindle will stop rotating.All measurement axis results can be displayed in real time on the computer screen, while the test curve is recorded and saved.
