Rod Reversal (Reciprocating Compressor)

A means of describing the changing compression and tension loads transmitted at the crosshead pin to the connecting rod bushing. Without proper reversing loads, the connecting rod bushing will not be adequately lubricated and will fail rapidly. The crosshead pin load reversal is defined by two components, degrees of reversal and percent loading, which represent the duration and magnitude of the load reversal. Both values must meet or exceed recommended manufacture’s minimum values. One manufacturer recommends minimum reversal parameters of 30 degrees of crank rotation and 25% magnitude.
