蒸--空两用模锻锤的铜套与锤杆处通常是藉助盘根来密封的,如我厂使用的M211模锻锤就是在填料盒里装上4圈YS450石棉盘根达到密封的。但当工厂采用的是饱和蒸汽作为传动介质时,由于含水量较大,加上锤杆润滑不够,这样盘根使用寿命极短,甚至只能用10～12个班就需更换,否则,漏汽、漏水,妨碍生产工人的操作。 Steamer - air dual-use forging hammer copper sleeve and hammer rod is usually sealed by the packing, as I used M211 forging hammer is filled in the packing box with 4 YS450 asbestos packing to achieve sealed. But when the factory is saturated steam as the transmission medium, due to the larger water content, coupled with the hammer lubrication is not enough, so packing life is very short, or even only use 10 to 12 classes need to be replaced, otherwise, the leak Steam, water leakage, hinder the production of workers.
