蒸汽—空气锤是用6～9个大气压的蒸汽或者5～7个大气压的压缩空气作动力的双作用锤。虽然从发明第一台蒸汽锤到现在已有140多年的历史,人们仍习惯于用蒸汽作为其传动动力。我厂自去年以来,先后对两台0.5t汽锤进行了改造,将其传动介质由蒸汽改为高压风,通过半年多的使用,工人反映良好。其主要优点是: ①消除了盘根漏汽漏油问题,改善了工人 Steam - air hammer is 6 ~ 9 atmospheric steam or 5-7 atm compressed air powered double acting hammer. Although it has been more than 140 years since the first steam hammer was invented, people are still accustomed to using steam as their transmission power. Since last year, our factory has successively reformed two 0.5t hammers and changed the transmission medium from high-pressure steam to high-pressure steam. After more than six months of operation, the workers reflected their good performance. Its main advantages are: ① eliminate the packing leak leakage problems, improve the workers
