Résumé

The lubricating oil used in the reciprocating compressor is located in the lower shell and with the operation of the crankshaft, oil climbs to helical channels on the crank shaft by the centrifugal forces. Oil is distributed from crank outlet and this ensures that all parts in the compressor are lubricated. The lubricating oil, which reaches the crankshaft bearings and other parts of the compressor prevents wear on the bearings and it also cools other components. Oil pump system includes both helical and centrifugal pump characteristics.
The aim of this study is to determine the oil pump design that gives the maximum oil flow rate at the crank outlet. A parametric numerical fluid dynamics analyses are performed to evaluate the effect of crank-screw pump geometric parameters, i.e., the number of screw-helix, screw form and depth between crank and screw. Results of this study are used in deciding the amount of oil to be used. In addition, the vortex effects in oil reservoir and its effects on sound power level of the compressor are investigated.
