Inspection of the anti-rotation pin for the small crosshead in reciprocating compressors
Thread Content
According to the maintenance procedures for piston compressors, it is necessary to inspect and tighten the crosshead anti-rotation pin during each minor repair. Which specific pin is meant by this crosshead anti-rotation pin, and where in the crosshead is it located?
I also don’t understand which specific component the original poster is referring to. In the piston assembly, there is a positioning pin between the piston and the piston rod; there is also a positioning key connecting the piston rod to the crosshead. Additionally, the bolts used to secure the crosshead come with lock washers to prevent them from loosening
