FIELD: mechanical engineering. SUBSTANCE: parts are placed into washing vessel 1-10 cu. m in volume which is then filled with liquid preheated to 50-90 C to leave liquid- free space. Vessel is sealed and partially evacuated by pumping away vapor-air mixture from liquid-free space. Reduced pressure is maintained for 1 to 20 min, whereupon vessel is communicated to atmosphere and liquid is poured out. EFFECT: facilitated treatment procedure. 18 cl, 10 dwg
