FIELD: process engineering.
SUBSTANCE: invention relates to machine building, particularly, to cleaning working fluid feed systems of impurities to preset tolerable level. Intake container is connected to system outlet union by pipeline with check filter. At least two equal-flow rate working fluid feeds are performed comparable with those in operating conditions. Equations are formulated for first and second feeds including volumes of used fluids in said feeds, and amount of impurities removed from the system and precipitated on check filter. Said equations are solved to define constants to formulate equation describing reaching preset cleaning level to be reached after third feed. This results in defining the volume of contaminated fluid to be removed from the system to comply with the requirements of testing particular aerospace equipment.
EFFECT: reduced labor input, higher efficiency.
