FIELD: mechanical engineering.
SUBSTANCE: invention relates to cleaning of metal parts from contamination in water alkaline solutions with application of ultrasound, in particular, to cleaning metal parts of bearings. Proposed method includes washing of parts in five baths of ultrasonic complex: in first bath containing degreasing water solution with MC-15 or MC-37 detergent, concentration of 20-25 g/l at temperature of solution within 60 and 70°C, in second bath with application of ultrasound in detergent TCM ("Gremlos B"), concentration of 20-30 g/l at temperature of 45-55°C, in third bath with application of ultrasound in not tap running water at temperature of 45-55°C, in fourth bath in cold tap running water, and in fifth bath in cold running distilled water with subsequent drying with hot air.
EFFECT: simplified method of cleaning , reduced labor input, increased labor productivity and improved quality of cleaning, reduced cost of cleaning.
