产品简介

Jinan platinum testing technology co., LTD. Is engaged in the research of the development and test technology of friction wear and lubrication evaluation test equipment.

Main production four-ball tester series, friction losses tester series, a ring of friction and wear testing machine series, long friction and wear testing machine series, the series of sliding bearing friction and wear testing machine and special functions such as high temperature, vacuum, and corrosion of friction and wear testing machine, a total of more than 30 varieties of specifications, can effectively simulate friction pair forms such as dot, line, face, realize the friction pair of dual rolling, sliding, skid, intermittent, reciprocating, composite motion in the form.

It is widely used in petrochemical industry, college and tribology.


执行标准

GB/ t12583-98 lubricant extreme pressure performance measurement (four-ball machine method)

Gb3142-82 lubricant carrying capacity determination method (four-ball method)

SH/ t0189-92 lubricating oil resistance measurement method (four-ball machine method)

Extreme pressure performance measurement of SH/ t0202-92 (four-ball machine method)

SH/ t0204-92 grease resistance test method (four-ball machine method)


功能特点

This machine is mainly in the form of sliding friction, and the bearing capacity of lubricant is evaluated under the condition of extremely high point contact pressure.

It includes three indexes, namely, the maximum unclamped load PB, the sintering load PD, and the comprehensive wear value ZMZ.

The machine can also be used as lubricant for long time wear resistance test, determination of friction coefficient, recording friction and temperature curve.

The machine is equipped with a high precision measuring device, which can be used to measure the spot size of the friction pair, or to display, measure and record the computer screen of the friction pair.

(1) carry out test methods such as GB/ t12583-1998 (lubricant extreme pressure performance measurement), ZB E 347-87 (four-ball method of anti-wear test method), etc.;

(2) real-time display of motor revolution (speed) and test duration;

(3) have multiple protection functions: friction, load, motor rotation, etc.;

(4) real-time recording of friction - time and load - time test curve, high-speed sampling;

(5) support iso-speed force and force to maintain closed-loop control;

(6) adopt the variable structure PID control algorithm to adjust the loading process, and the constant speed control error is less than 5%, and the pressure control error is less than 0.5%;

(7) when the test force is greater than a certain limit, the system will automatically enter the overload protection and take certain measures in time to ensure the safety of the testing machine;

(8) the test data shall be managed by data files, and all test data and curves can be saved. The format of the test report shall meet the requirements of the national standard.
