Which components can be damaged if the piston rod vibration exceeds the limit (set at 0.08 mm)?
Is the piston rod runout exceeding the limit? What are the standards? What is this piston compressor suitable for? What is the pressure? What’s the speed? I haven’t heard of a heartbeat value either? ? Thank you!
Excessive piston rod vibration can damage the piston rod seals, piston rings, and so on.
Large piston rod vibration is caused by misalignment between the cylinder and the crosshead slideway, and it may lead to wear of components such as the cylinder block or piston ring supports
Those in direct contact with the compressor shaft, such as packing, support rings, etc
When the piston rod has a large amount of play, it can affect the packing seal, as well as the piston sealing ring or support ring.
Piston rings and support rings should have a fixed schedule for inspection and replacement
Large piston rod play has a significant impact on the wear of the crosshead shoes and guides, as well as on the packing, piston rings, and support rings.
