摘要
通过对活塞杆疲劳断裂原因的理论分析和计算,提出了提高活塞杆预紧段弹性的观点,介绍了防止活塞杆断裂的历次改造过程。
This article analyzes and calculates the fatigue breaking theory of piston pole, presents the viewpoint of improving the pre-tightening part's elasticity of piston pole, introduces all previous alteration course to prevent piston pole from breaking.
