蒸汽、空气两用模锻锤,通常用盘根进行密封。在填料盒里装几圈 YS4507棉盘根,然后压紧压盖。为了取得较好的密封效果,往往把压盖压得过紧,(?)至使工作部分运动不灵活,盘根寿命很短,只能用十几个班。为延长盘根寿命,我们采取一副 V 型热性塑料盘根,其余仍用 YS450石棉盘根,每班往锤杆上注5～6次中质润滑油,这样既保证了设备的运动特 Steam, air dual-use forging hammer, usually sealed with packing. Install a few turns of YS4507 cotton packing in the stuffing box and squeeze the gland. In order to obtain a better sealing effect, the gland is often pressed too tight (?) To make the work part of the movement is not flexible, packing life is very short, can only use a dozen classes. To extend the life of the packing, we take a V-type thermosetting plastic packing, the rest are still using YS450 asbestos packing, each class to the hammer on the injection of 5 to 6 times the quality of lubricants, so that not only ensure the equipment movement
