As the title suggests, how is excessive piston rod vibration usually adjusted?
If the piston rod vibration is beyond the acceptable limits, first check the inner diameter of the cylinder to see if there is any wear. Level the cylinder. For cylinders, the middle section of the body, and the fuselage, check the installation accuracy to ensure they are all on the same center line. Damage to the packing or stuffing box can also cause vibration. Let’s take a look at the installation clearance of the crosshead, etc.
It’s quite comprehensive; it can be checked item by item
Replace the support ring, add shims to the crosshead slip, adjust the top flange...............
Generally, the levelness of the cylinder is adjusted; the API standard specifies this value as \"0.07 MM\".
