Help: What connects the crosshead to the piston rod in a reciprocating compressor? What are the installation components? What should be taken into consideration during installation? Which components need to be installed inside the piston rod before connecting other components?
The connection between the crosshead and the piston rod is generally achieved through bolted connections; of course, some designs include components such as double-ring seals. With regard to installation requirements, the following points must be ensured: 1. Reliable connection; 2. The clearance at the end positions should be adjusted to an appropriate level; 3. The piston rod and the cylinder block must be highly concentric after installation

Install the stuffing box and piston rings as well as support rings; use a protective cover to safeguard the threads of the piston rod. Once it is in place, be careful to protect those threads while slowly rotating the piston. After reaching the desired position, measure the end-stop clearance, and tighten the nut once it meets the requirements. Measure the gap above and below the slide.
