This model is a computer-controlled “FULLY AUTOMATED” reciprocating friction and wear test system which provides a fast, repeatable assessment of the performance of fuels and lubricants. It is particularly suitable for wear testing of relatively poor lubricants & diesel fuels for boundary friction measurements of engine oils, greases & other compounds. Developed by a group of Tribologists having a combined experience of over 60 years in the field of Tribology.
The test method measures the lubricity, or ability of a fluid to affect friction between, and wear to surfaces in relative motion under load. The system is entirely controlled by a PC via a custom electronic interface. The entire process from the loading of the specimen, attaining the temperature, achieving the required pre-defined frequency to maintaining the required defined/set load during the test duration (please note that the load tends to increase due to the heating of the specimen & the test sample), controlling the stroke length to the:-
is automated and controlled by the software.
All the test parameters can be pre-defined / or set manually for the test sequence and controlled by simple menu-driven control software. The software times the test and logs friction coefficient, temperature & specimen contact resistance at user-defined intervals.
The mechanical unit uses an electromagnetic drive to oscillate the upper test ball against a fixed lower plate/disc. The digital control system and the absence of bearings and sliding components in the mechanical unit ensure absolute repeatability of stroke length and frequency. Accurate & repeatable loading is ensured by using an automated loading arrangement (not a dead weight loading arrangement used normally). Platinum RTD temperature probes are used for the specimen and safety cut-out temperature measurements. Piezoelectric transducers are used for very precise measurements of load, friction & amplitude/stroke length. Humidity probe to record the RH trace in the bath in the software.
Collected data is displayed in a graph form during the test. It is continuously updated, saved in text format, and can easily be recalled (online during the test/offline from recorded data) and printed.
|WEAR SCAR MEASUREMENT:-|
Wear scar measurements/dimensions are done automatically (in the x, y & z axis) thru the microscope and saved in the respective test data/log file automatically for online/offline analysis.
State-of-the-art menu-driven software is used for running the tests & recording the data. The software also allows multiple temperature steps & ramps during a single test – widely used for lubricant boundary friction measurements. The software allows the user to pre-define the graphs and recall the earlier recorded test data online (real-time: during the test) for off-line analysis:
The software controls to ensure the user-set limits to maintain the safety of the equipment and will shut down in case of any failure due to any reason.
