MRS-10A Microcomputer Screen Display Four Ball Friction Testing Machine
The MRS-10A microcomputer screen display four ball friction testing machine mainly evaluates the bearing capacity of lubricants in the form of sliding
Product details
The MRS-10A microcomputer screen display four ball friction testing machine is mainly divided into two types: hydraulic control loading and microcomputer control loading, both of which can achieve four ball friction testing and complete lubricating oil quality identification.
MRS-10A Microcomputer Screen Display Four Ball Friction Testing MachineThe bearing capacity of lubricants is mainly evaluated in the form of sliding friction under extremely high point contact pressure conditions. Including three indicators: maximum non card bite load PB, sintering load PD, and comprehensive wear value ZMZ. This machine can also perform long-term wear resistance tests on lubricants, measure friction coefficients, and record friction and temperature curves. The machine is equipped with a high-precision measuring device that can measure the size of friction pair wear spots, or achieve computer screen display, measurement, and recording of friction pair wear spots.
The machine adopts an integrated structural design, integrating computer, software, industrial control modulesactuatorCombine within a framework to control the entire experimental process. Test force loading method: microcomputer controlled hydraulic automatic loading. Software main interface: It can display real-time parameters such as test force, friction torque, spindle speed, test temperature during operation, and friction coefficient. Experimental data and curves: can be stored, accessed, printed and output as desiredTest ReportWait.
