FOAMING CHARACTERISTICS OF LUBRICATING OILS
The Foam instruments are used to detect undesirable foaming characteristics in lubricating oils, which could cause inadequate lubrication, overflow and cavitation.
To avoid mechanical failure, the test measures the foaming characteristics of lubricating oils at different temperatures by empirically rating the foaming tendency and the foam stability.
For sequences I, II, III,
Single test unit
Test at 24 and 93.5°C once at a time
Foam performs two tests at 24°C and two tests at 93,5°C. The instruments are equipped with 2 heat resistant glass jars (with temperature controller), 2 flowmeters, 2 cylinders (1000 ml), immersion heater, stirring system air delivery tubing and thermometer. Cold bath has built-in coils for circulating exit air from the high temperature test cylinders.
Cryostat is necessary, only for a test at 24°C –
– 2 diffusers,
– 2 test cylinders
– 2 flowmeters.
