Piston rod runout issue
Thread Content
The horizontal deviation of the piston rod in a reciprocating compressor is too large (0.07 mm); from which aspects should the issue be addressed?
A variation of 0.07mm isn’t that large. If you really want to make adjustments, you can try adjusting the level of the cylinder
The horizontal runout tolerance of 0.07 mm is not considered large.
For piston rod vibration, the coaxiality of the cylinder block and the crosshead slideway can be adjusted, which helps to reduce such vibration
Large horizontal movement of the piston rod indicates that the coaxiality between the slide and the cylinder is not up to standard
If the horizontal deviation of the piston rod is out of tolerance, 1) the coaxiality between the cylinder body and the crosshead slideway can be adjusted; 2) it is necessary to check whether the perpendicularity of the joint surface between the cylinder body and the intermediate piece meets the requirements
