Category Title
In the gas compression machinery business, reciprocating compressors are generally run with higher rotational speed compared to the API 618 market. This higher speed needs to be carefully introduced in the hydrodynamic design of the plain bearings. One thing is the higher frictional heat introduced in the bearing by the higher speed. The oil consumption must be checked for this heat in order to remove it by the oil flow. Another thing is the hydrodynamic load capacity increase by the higher speed. The paper will demonstrate this effect on the basis of the theory and example calculations. The crosshead pin bearing design is more critical than main and crank pin bearing design since this bearing must be checked for a minimum rod load reversal. The rod load reversal demand will be explained on the basis of a new design tool the author has developed. One of the critical design parameters concerning this effect is the rotational speed. Unfortunately, higher speeds need more absolute rod load reversal angle than lower speeds. This fact can be demonstrated with simple formulas and animated hydrodynamics.
