The foaming tendency analysis assesses how easily an oil foams and how quickly the foam breaks down -- important in high-agitation systems such as gearboxes and hydraulics. Excessive foam can lead to air leakage, loss of lubricity and cavitation.
The oil is blown through with air under controlled conditions in three stages (I, II and III) simulating different operating conditions. The amount of foam and the decomposition time are measured.
The customer gains insight into the air separation properties of the oil and whether problems may arise during operation that require action or oil change.
