The test rigs purpose is the testing of oil mist separators re capture rate, flowrate curve (pressure loss relative to flowrate), pressure regulation curve and leakage. The unit to be tested will be fed with an oil aerosol (flowrate and temperature adjustable) either in positive or negative pressure conditions. The immediate vicinity of the filter is temperature controlled. During the collection efficiency measurement the separated and the let-to-pass oil amounts are measured in dependence on the volumetric flow. They are automatically recorded, applying the gravimetric method, by means of an absolute filter. The amount of oil leaving the separator can be recorded online. Additionally, the leakage of the oil drain valve can be measured. The test rig simulates the operating conditions in typical fields of oil aerosol separator application. When recording the pressure control characteristic, the pressure in the crankcase“ is simulated in dependence on the „suction pipe pressure“ for different flow rates.
