五一小长假FESTO气缸*德国费斯托气缸 气缸常见问题及原因分析:
1．汽缸是铸造而成的，汽缸出厂后都要经过时效处理，使汽缸在住铸造过程中所产生的内应力*消除。如果时效时间短，那么加工好的汽缸在以后的运行中还会变形。 　　
2．汽缸在运行时受力的情况很复杂，除了受汽缸内外气体的压力差和装在其中的各零部件的重量等静载荷外，还要承受蒸汽流出静叶时对静止部分的反作用力，以及各种连接管道冷热状态下对汽缸的作用力，在这些力的相互作用下，汽缸易发生塑性变形造成泄漏。 　　
3．汽缸的负荷增减过快，特别是快速的启动、停机和工况变化时温度变化大、暖缸的方式不正确、停机检修时打开保温层过早等，在汽缸中和发兰上产生很大的热应力和热变形。 　　
4．汽缸在机械加工的过程中或经过补焊后产生了应力，但没有对汽缸进行回火处理加以消除，致使汽缸存在较大的残余应力，在运行中产生*的变形。 　　
5．在安装或检修的过程中，由于检修工艺和检修技术的原因，使内缸、汽缸隔板、隔板套及汽封套的膨胀间隙不合适，或是挂耳压板的膨胀间隙不合适，运行后产生巨大的膨胀力使汽缸变形。 　　
6．使用的汽缸密封剂质量不好、杂质过多或是型号不对；汽缸密封剂内若有坚硬的杂质颗粒就会使密封面难以紧密的结合。 　　
7．汽缸螺栓的紧力不足或是螺栓的材质不合格。汽缸结合面的严密性主要靠螺栓的紧力来实现的。机组的起停或是增减负荷时产生的热应力和高温会造成螺栓的应力松弛. 163447 DNC-80-25-PPV
