电液锤是一种新型的锻造设备,由于其节能显著,我车间先后将1t、2t、3t自由锻空气锤改造成为电液锤。但由于锤杆动作频繁(50～70min~(-1))且常承受偏心载荷,下封口经常漏油,密封寿命短,每月更换一次,维修费用高,并影响安全生产。对此,我们将其结构进行了改进。 Electro-hydraulic hammer is a new type of forging equipment, due to its significant energy-saving, I have workshop 1t, 2t, 3t free forging air hammer transformed into electro-hydraulic hammer. However, due to the frequent hammer rod movement (50 ~ 70min ~ (-1)) and often subject to eccentric load, the lower seal often leak oil, short seal life, once a month, high maintenance costs and affect safety in production. In this regard, we have improved its structure.
