密封垫料在往复运动的部件中往往起着十分重要的作用。近年来由于密封新材料的不断涌现,给我们设备维修带来了许多方便。我厂3.15吨蒸空两用模锻锤(沈重厂产品),由于锅炉房远离车间,配汽小缸内活塞杆漏汽漏水十分严重。针对这个情况,我们对该设备性能和结构的合理性进行了探讨。一般锻锤都采用两种方法来密封小缸活塞杆:(1)填料压盖密封如图1,这种密封效 Gaskets often play a very important role in reciprocating parts. In recent years due to the continuous emergence of new sealing materials, to our equipment maintenance has brought a lot of convenience. I plant 3.15 tons of dual-use vacuum forging hammer (heavy plant products), as the boiler room away from the workshop, with steam cylinder piston rod leakage leakage is very serious. In response to this situation, we discussed the rationality of the device performance and structure. General forging hammer adopts two methods to seal the small cylinder piston rod: (1) packing gland seal shown in Figure 1, this sealing effect
