The reciprocating machine’s piston rod cannot be separated from the pressure application unit
Thread Content
The piston rod of the reciprocating machine cannot be separated from the pressure chamber; there are scratches on the inside of the pressure chamber, which is suspected to be damage caused during initial installation. The crosshead and the pressing element have separated, but when trying to remove the pressing element downward from the piston rod, it won’t come off. Is there any solution? Can Ramallah be used?
When you can’t take it out gently, you have no choice but to wrap it up
If there is a spare pressure body, turning can be considered
Based on what you’ve described, it seems that the pressure element may be slightly skewed when under pressure, or there might be hard debris trapped in the gap between the pressure element and the piston rod, which causes the two components to stick together when trying to remove the pressure element. As a preliminary measure, you could try shaking the pressure element axially inward, then use steam to heat it up and attempt to remove it to see if that helps. You can’t force it; if you delve too deep, it will only be destroyed.
Our company also encountered a similar situation; in the end, we had no choice but to obtain a level 1 fire permit and cut the piston rod, as it couldn’t be removed and thus couldn’t be turned
Is it the previous picture? Let me show it to you – here’s a version with both text and images
