FIELD: galvanochemical treatment of parts. SUBSTANCE: invention deals with galvanochemical treatment and cleaning of surfaces of parts with use of both heated and cold electrolytes and solutions in main technological baths, process can be applied in operational production and production under development. Process includes successive execution of operations of basic galvanochemical treatment by submersion method in processing bath, jet flushing ( with recuperation of jets of flushing water ) and flushing of surfaces of parts by submersion method in corresponding baths, making up for loss of volume of electrolyte ( solution ) in processing bath with portion of spent water which concentration was raised with water formed after first flushing or at start of jet flushing, feeding it into flushing bath with overflow pocket for flushing surfaces of parts by submersion method. It should be cleaned from key washed-away component of electrolyte ( solution ) of processing bath, cleaned flushing water should be replenished in corresponding tank-collector, this water can be used for operation of jet flushing with the aid of local pressure system with condensed evaporation formed in process of concentration of spent electrolyte, and/or with distilled water of proper generator, and/or with recuperated portion of flushing water utilized in jet flushing, and/or after it. In this case jet flushing is realized in the form of stage of mutually interconnected operations with n-step jet flushing distributed in baths with proper local pressure systems ( where n is integral number n≥2) ). Outlet of each subsequent jet flushing is linked directly or through proper collector-metering tank to proper local pressure system with distribution collectors with elements which form jets of preceding stage of jet flushing. Inlet of last step of jet flushing is connected either directly to bath of submersion flushing or through collector-metering tank with overflow pocket. When key washed-away component of electrolyte ( solution ) of processing bath reaches maximum permissible concentration in flushing bath of submersion method electrolyte ( solution ) in the latter should be drained completely or partially into tank for discharge of contaminated flushing water. Outlet of tank is linked through proper actuating element to inlet local pressure system of last step of jet flushing. Same water is utilized in realization of last step of jet flushing in last bath of jet flushing. EFFECT: widened functional and technological capabilities, increased efficiency and productivity of process, decreased energy consumption for operations of recuperation of treating media ( electrolytes, solutions, flushing water ) in technological process. 6 cl, 1 dwg
