Claims (1)

Способ восстановления соединений типа “плоская золотниковая пара”, включающий упрочнение охватывающей поверхности методом электроискровой наплавки, отличающийся тем, что охватывающие поверхности после выведения следов износа шлифованием упрочняют графитовым электродом на режимах с энергией разряда 0,13-0,28 Дж, удельным временем упрочнения 1,5-3 мин/см2, при частоте вибрации электрода 200-250 Гц, при износах золотников до 60 мкм на сторону восстановление золотника осуществляют алюминиевыми или алюминиево-марганцевыми бронзами на режимах с энергией импульса 0,81-1,66 Дж, удельным временем наплавки 2-2,5 мин/см2, при частоте вибрации электрода 200-250 Гц с их последующей шлифовкой и доводкой.A method of reconditioning compounds of the “flat spool pair” type, including hardening of the enclosing surface by the method of electrospark welding, characterized in that the enclosing surfaces after removing traces of wear by grinding are hardened with a graphite electrode in modes with a discharge energy of 0.13-0.28 J, specific hardening time 1 5-3 min / cm 2 at a frequency of 200-250 Hz vibration electrode, when worn spools to 60 microns to the side of recovery of the spool carried by aluminum or aluminum-manganese bronzes on modes with nergiey pulse 0,81-1,66 J surfacing specific time 2-2.5 min / cm 2 at a frequency of 200-250 Hz vibration electrode with subsequent grinding and lapping.
