How is the piston rod length of a reciprocating compressor determined?
Thread Content
I can’t find any relevant standards or calculation methods. Personally, I think it should be the stroke distance + the length of the stuffing box + the length of the overlapping part between the piston rod and the piston + the clearance between the crosshead and the cylinder during the movement of the cover. I’m not sure if this is correct; those who know more on this topic are welcome to offer their guidance
Reply to 1# hunands: It is a complex calculation process for closed dimension chains. Simplified, it is: the distance from the crankshaft’s centerline to the inner end surfaces where the cylinder block and cylinder head meet (that is, the distance from the crankshaft center to the top dead center position) – the crankradius – the distance between the crankpins – the distance from the crosshead center to the top surface + the depth to which the piston rod is screwed into the crosshead + the total thickness of the piston nut – the clearance between the upper and lower dead centers of the piston (usually 5–6 mm). I hope this helps you
This should be related to the stroke of the cylinder; I’ve learned about it
