FIELD: electroplating. SUBSTANCE: method may be used in treatment of printed circuit-boards and articles of electronic engineering, in flushing of machine parts after their treatment in process baths (degreasing, pickling, chrome-plating, galvanizing, copper plating, etc.) under conditions of limited operating areas, higher requirements imposed on consumption of flushing liquid, volume of sewage waters and screening of splashes of treating medium in jet cleaning process. In claimed method of jet flushing of machine parts on suspensions including supply to surface of suspensions moved in vertical plane with machine parts of bundle of parallel jets of flushing liquid from its source, formed by corresponding members staggered on distributing headers and also catching and localizing at least in width and height of formed zone of bundles of parallel jets, parts of non-engaged in the course of flushing jets of washing liquid with the help of correspondingly arranged pipelines, connected with source of washing liquid, first execute preliminary washing off electrolyte carried by machine parts from process bath with the help of additional distributing headers with corresponding members forming jets located in bath upper part above distributing headers with members forming bundles of parallel jets of washing liquid. In this process, splashes are screened and diluted electrolyte is caught and localized for its reuse in operation of main galvanochemical treatment. In the course of flushing of machine parts by bundles of parallel jets of washing liquid, splashes are screened and contaminated washing liquid is caught and localized for its reuse, after respective purification, at least in operations of preliminary washing off of electrolyte. Members forming bundles of parallel jets of flushing liquid are located directly in correspondingly arranged pipelines connected with source of washing liquid. Regulation of at least flow rate and/or pressure of jets of purified washing liquid supplied to additional distributing headers is effected by controlled bypassing of supplying pipeline or its throttling, variation of quantitative parameters and/or orientation of respective members of jet formation, or by variation of speed of unloading of machine parts from bath of jet flushing. EFFECT: reduced consumption of washing liquid, extended functional and technological potentialities and improved labor conditions. 6 cl, 2 dwg
