Abstract
A reciprocating piston compressor (100) includes a crank casing (10). The reciprocating piston compressor (100) includes a crankshaft (11), a piston rod (12) and a crosshead (13). The crosshead (13) and the piston (23) are actively connected to one another by way of a connecting rod (24). The connecting rod (24) is fixedly restrained on the crosshead (13) and on the piston (23).
Claims20
A reciprocating piston compressor comprising:
- a crank casing;
- a crankshaft;
- at least one piston rod arranged on the crankshaft;
- a crosshead configured as a guide piston, the piston rod being actively connected to the crosshead;
- at least one cylinder;
- a piston movably arranged in the cylinder;
- a connecting rod, wherein the crosshead and the piston are actively connected to one another by way of the connecting rod, wherein the connecting rod is connected to the crosshead with a first fixed restraint and the connecting rod is connected to the piston with a second fixed restraint, the connecting rod being configured such the connecting rod permits alignment errors between the crosshead and the piston via one of deformation of the connecting rod and deflection of the connecting rod.
A retrofit kit for a reciprocating piston compressor comprising a piston rod, a crosshead, a piston and a connecting rod, wherein the crosshead and the piston can be brought into active connection with one another by way of the connecting rod, wherein the crosshead and the piston each comprise a receiver for a fixed restraining of the connecting rod, the connecting rod being configured such the connecting rod permits alignment errors between the crosshead and the piston via one of deformation of the connecting rod and deflection of the connecting rod.
A reciprocating piston compressor comprising:
- a crank casing;
- a crankshaft;
- at least one piston rod arranged on the crankshaft;
- a crosshead configured as a guide piston, the piston rod being actively connected to the crosshead;
- at least one cylinder;
- a piston movably arranged in the cylinder;
- a one-piece integrally formed connecting rod, wherein the crosshead and the piston are actively connected to one another via the one-piece integrally formed connecting rod, wherein the connecting rod is connected to the crosshead with a first fixed restraint and the connecting rod is connected to the piston with a second fixed restraint, the one-piece integrally formed connecting rod comprising a one-piece integrally formed connecting rod extent extending between an end of the piston and an end of the crosshead, wherein only a portion of the at least one cylinder surrounds the one-piece integrally formed connecting rod extent, wherein no other structure is provided radially between the one-piece integrally formed connecting rod extent and an inner surface of the at least one cylinder with respect to a longitudinal axis of the at least one cylinder.
