Product Name: MRS-10AMicrocomputer controlled four ball friction and wear testing machine
1、 Equipment Introduction
The MRS-10A microcomputer controlled four ball friction testing machine is mainly used in the form of sliding friction to evaluate the bearing capacity of lubricants under high point contact pressure conditions. Including maximum non card bite load PBSintering loadPDComprehensive wear valueThree indicators including ZMZ. This machine can also perform long-term wear resistance tests on lubricants and measure the friction coefficient. After connecting to the computer, friction and temperature curves can be recorded. If special friction accessories are used, rolling friction tests, simulated wear tests between various materials, end face wear tests, and steel ball rolling fatigue tests can also be conducted. The lever type four ball friction testing machine developed and produced by our company can continuously load test forces. In addition to the test force level required by standard methods, the required test force can be set arbitrarily by the computer to achieve the function of an electro-hydraulic servo four ball machine.Applicable standards for this machine:
GB/T12583-98Lubricant extreme pressure performance determination method (four ball machine method)
GB3142-82Lubricant bearing capacity determination method (four ball method)
SH/T0189-92Measurement method for anti-wear performance of lubricating oil (four ball machine method)
SH/T0202-92Lubricating grease extreme pressure performance determination method (four ball machine method)
SH/T0204-92Determination method for anti-wear performance of lubricating grease (four ball machine method)
SH/T 0762-2005|Measurement method for friction coefficient of lubricating oil(Four ball machine method)
ASTM D5183-2005Test method for determining the friction coefficient of lubricating oil using a four ball wear tester
In practical applications, users can choose different measurement methods and evaluation indicators based on the various uses of lubricants.
