L-60-1 Performance Test Apparatus
Performs the L-60-1 Thermal Oxidation Stability performance test for API GL-5
gear lubricant service. Consists of a standardized gear box assembly with
motor drive system and digital indicating controls for all test functions.
Gear Case and Drive System
Two spur gears and a test bearing are operated inside a machined stainless
steel case with removable window. The drive gear shaft is coupled to a heavy
duty ball bearing motor loaded by a 45 ampere alternator. The standard L-60-1
test gear loading value of 128 watts generator output is precisely maintained
by a digitally indicated load bank. All gear box components are easily
accessible for cleaning.
An insulated heating case with high volume blower encloses the gear box.
Sample oil temperature is maintained at 325 ± 1°F (162.8 ± 0.6°C) by a
digital indicating controller with PT-RTD sensor. A built-in microprocessor
based recorder produces a test oil temperature chart for reporting purposes.
Over-temperature protection is provided by a separate PT-RTD-sensed
Air Flow Control
A high accuracy mass flow controller with digital indication maintains air
flow to the gear box at a constant 1.1L/h. The self correcting controller
maintains the setpoint flow rate regardless of fluctuations in air input
pressure or temperature. Test cabinet and control cabinet are finished in
chemical resistant polyurethane enamel. Test cabinet has a cover for access
to the gear box and a removable drive motor cover.
