Imperial (Computer Controlled) High Frequency Reciprocating
(Oscillating Friction & Wear) test m/c ASTM
Specifications : D-6079
Comprises
of
Imperial HFRR is a
computer controlled reciprocating oscillatory friction & wear test
system which provides a fast, repeatable assessment of the performance
of fuels & lubricants. It is particularly suitable for wear testing
of relatively poor lubricants like diesel fuels, and for boundary
friction measurements of engine oils, greases & other compounds.
This
fully automated system has an automated
1. Loading system (Motorized)
2. Temperature controls
3. Frequency
4. Amplitude
5. Test duration
The system is entirely
controlled by an IBM compatible PC (Pentium PIII 750 MHz), via a custom
electronic interface and comes with a variety of test specimen
geometries; Point, line & area (the user MUST specify the materials
required while ordering). Once the specimens have been loaded the rest
sequence is completely automated with all its parameters set by the
menu-driven control software. The software pre-heats the specimens upto
the test temperature then starts the test, controlling .Load, Frequency,
Stroke length/Amplitude & temperature to very precise limits.
It also times and logs
friction coefficient, Temperature & Specimen Contact resistance at
user defined intervals.
1. The mechanical unit
uses an ELECTROMAGNETIC DRIVE to oscillate the upper test specimen
against a fixed lower plate/specimen. The digital control system,
absence of bearings & sliding components in the mechanical unit
ensures absolute repeatability of stroke length & frequency.
Accurate Platinum RTD temperature probes are used for specimen and
safety cut-out temperature measurements.
2. For on-line wear monitoring system a LVDT is incorporated with an
accuracy of 0 to 1 mm with a resolution of 0.2 .m.
3. Comes with a Peristaltic pump with adjustable flow (0.02 ml/min to
0.2 ml/min) of test lubricant for DRIP / SPLASH arrangement. Collected
data is displayed on-line/Real time in graph form as the test proceeds.
It is continuously updated and saved on the hard disc and can be easily
re-called & printed. Wear Scar dimensions & operator.s comments
can be recorded to provide a complete hard copy of each test.
