Welcome: U-THERM INTERNATIONAL (H.K.) LIMITED
Main purpose:
This machine is used to evaluate the loading capacity of lubricants in the process of sliding friction on a contact point under very high pressure. It meet requirement of <GB/T 3142 Lubricants-determination of load-carrying capacity(four balls method)> The above mentioned capacity including 3data to be tested: The maximum load PB under the unstuck condition, sintered load PD and comprehensive value of wearing during friction ZMZ. The machine can carry on abrasive wearing test for a long period in order to appraise friction and obtain the coefficient of friction of the material. Can be carried on when the machine is equipped with special accessories. And the computer can writer temperature-hour-out line, the friction-hour-out line when link up with the computer. The screen can demonstrate measures and records the data from the computer when the machine is equipped with the peculiar measurement device.
