Reciprocating compressor structure
Thread Content
Hello everyone, does anyone know what the part marked in the red circle in this picture is used for? What’s the structure inside?
The cylinder head is used to seal the cylinder; inside the cylinder there are typically a cylinder liner, piston assembly (piston body, piston rings, guide rings, piston rod, piston rod nut), oil injection holes, and more. It can generally also be used to adjust the cylinder clearance (by appropriately adding or removing gaskets on the cylinder head); some cylinder heads are also equipped with cooling water to lower the temperature of the medium inside the cylinder (the cylinder may also have a water jacket).
It shouldn’t be all cylinder end caps; the one in the middle should be a cylinder end cap, while the two on top and bottom should be machining holes
The middle one is the cylinder head; the ones on top and bottom should be the covers for the water jackets
Middle cylinder head; the upper and lower ones are process hole covers for cleaning the water jacket
Thank you all. I’ve never seen the disassembly of a cylinder block of this type before; I didn’t know about its structure and couldn’t find any diagrams of it{:1_90:}
In the middle is the cylinder head, while the ones on top and bottom are process holes used for machining the intake and exhaust chambers; since it is a forged steel part, the air chamber in the middle is created by removing material from there； Waterways are usually on two sides; they’re not in this location ；
The cylinder head. Once it’s opened, the piston is inside.
