Steam-Air Hammer

The contents of the paper include:the comparison of the electrohydraulic hammer and the steam—air hammer;

其中包括：电液锤与蒸汽-空气锤工作状况的比较；

The loose tooling forging of half shaft bushing on the steam-air forging hammer is numerically simulated using FEM software DEFORM3D.

采用商用有限元软件DEFORM3D对半轴套管胎模锻成形过程进行了计算机模拟。

The solution of problems such as water hammer, hard to dispose the noncondensables, air lock and selection of steam trap were discussed to save energy, protect environment and lower the cost.

指出蒸气凝结水回收的重要性的同时对炼油厂蒸气凝结水回收系统中存在的诸如水击、非凝结性气体不能排除、气阻及疏水阀的选型安装等问题的解决办法进行了探讨。
