螺栓中间有孔的话,说明需要电加热 或者液压扳手 3 最后不行的话,只能割断,

两把焊炬加热,用专用扳手加钢管,再用铁锤敲击

加松动剂、烤、加长扳手使劲搞

说一下,首先我是干设备的,厂里装机容量有40MW,不大,共8台机子,除非气缸螺栓损坏(金相、强度、硬度检验),否则是不动它的,要是真的拆,估计就是进行破坏了,但是可以考虑把气缸翻过来,垫平后,下摇臂钻。但是气缸螺丝的硬度,你应该知道的。至于用火焊,能操刀的焊工可遇不可求。

松动剂热处理,最后霸王硬上弓

没有液压扳手吗, 另外,试过将铜棒垫在螺帽上,用大锤垂直向下砸吗,使劲砸可以使其变松,然后用敲击扳手加加力杆,或者用大锤砸敲击扳子,没有拆不下的螺丝,除非里面的丝咬了或者螺丝是液压螺母

汽轮机温度高,大盖螺栓温度降下来之后再去拆卸很容易滑方,最好用气焊烤一下,热涨以后用敲击扳手套上长杆拆卸

有汽轮机螺丝专用加热器
Reply #132017-03-22
推荐松动剂,其次热处理

直接用气割枪割开螺帽,拆下后换新的。用bao li拆除法!:lol
