FIELD: treatment.
SUBSTANCE: invention relates to ultrasonic treatment of hollow articles and can be used for recovery of operational characteristics of burner devices of engines. Process line for cleaning channels of fuel supply elements of an external or internal combustion thermal engine has a unit for diagnosis of degree of clogging of channels before and after cleaning and a unit for ultrasonic cleaning UUO of clogged channels in a liquid cleaning medium. First stage involves visual inspection of elements and using calibrated rods KST checking outlets of all fuel channels and mapping clogging of channels. Then blowing device UP is connected and channels are blown with gaseous or liquid agent under pressure. Elements are then directed into UUO, equipped with means for sampling and analysing COA composition of deposits to be cleaned. UUO COA is a furnace for thermal treatment of deposits, an impact tool, grinding tool for processing a collected sample and scanning electronic microscope for analysing a sample slide. Based on analysis most effective detergent is chosen. Then burner is immersed into solution, which is an ultrasonic generator USG is placed. After cleaning burner is again fed into UD 1 for repeated diagnosis. Cleaning completed if result is positive, otherwise burner is directed into UUO for repeated cleaning.
EFFECT: technical result is simpler and more qualitative diagnosis of state of controlled channels, their more qualitative cleaning due to improvement in ultrasonic cleaning process of detergent properties of cleaning medium.
