Abstract
Способ ремонта гидрораспределителей, включающий обработку золотниковых отверстий алмазной разверткой до выведения следов износа по наиболее изношенному пояску, нанесение на рабочие пояски золотников слоя из низко- или среднеуглеродистой стали методом электроискровой обработки в механизированном режиме, последующую укатку и притирку рабочих поясков золотников, нанесение на них методом финишной антифрикционной безабразивной обработки пленки из латуни, шлифовку гнезда клапана до образования острой кромки отверстия, выведение механообработкой следов износа уплотняющей конусной поверхности клапана, притирку клапана к гнезду до образования блеска на притираемых поверхностях, отличающийся тем, что уплотняющую конусную поверхность клапана после удаления следов износа упрочняют электродом из твердого сплава методом электроискровой обработки на установке с энергией разряда 0,13-1,66 Дж.A method of repairing control valves, including processing spool holes with a diamond sweep to remove traces of wear on the most worn out belt, applying a layer of low- or medium-carbon steel to the working spools of the spools by electrospark machining, subsequent rolling and grinding of the spools of the spools, applying them to the method finishing anti-friction non-abrasive processing of a film of brass, grinding the valve seat to form a sharp edge of the hole, removing mechanical processing traces of wear of the sealing conical surface of the valve, grinding the valve to the socket until a luster is formed on the grinding surfaces, characterized in that the sealing conical surface of the valve after removing traces of wear is strengthened by a carbide electrode by spark treatment in a plant with a discharge energy of 0.13-1, 66 J.
