APPARATUS FOR EVALUATING QUALITY OF LUBRICATING OIL Russian patent published in 2012 - IPC G01N17/00 G01N33/26 

FIELD: physics.

SUBSTANCE: apparatus for evaluating quality of lubricating oil has an oil tank with a cover, an oil pump, a heating element with a heat exchanger and a gear friction couple connected through oil pipes for feeding and discharging oil into a closed loop. In the oil pipe for discharging oil there is a sealed test chamber with test specimens of structural and sealing materials which can be adjusted on the setting angle relative the oil current. The test chamber has a removable cover in which there are cross beams for mounting the specimens, and thermocouples at the oil inlet and outlet of the chamber, and the removable cover of the oil tank is configured for installation inside above the level of the oil of the test specimens for evaluating effect of oil vapour thereon.

EFFECT: broader functional capabilities of the device for obtaining additional data on the effect of aviation oil on structural and sealing materials when covered by oil and in oil vapour.
