如果超过设计压力的话,肯定会出问题,连续频繁出问题,先确定下材质是否有问题,再看看工艺操作参数是不是偏离设计太多了。

多台同时出问题应该不是设备问题!工艺找原因!

全面检查工艺操作参数是否在设计范围之内。

要是经常发生这样问题,你可以联系我,把活塞杆给你改进一下

如果工艺运行时,系统压力正常,波动峰值不超的话,严重怀疑设备设计偏离过大导致设备质量不合格所引起的断裂。 如果拉杆没有明显弯曲,说明是强度不够。

由于活塞杆承受的是交变应力,因此对于活塞杆上的螺纹的加工要求很高,一般采用辊压出来,这样可以避免在螺纹根部产生微裂纹,从而引起应力集中,造成螺杆断裂,刚才看图片,怀疑你们的活塞杆螺纹是直接车削出来的,这样的螺纹容易出现断裂的问题。
