Abstract

The purpose of this paper was to evaluate the electromotor input power loss caused by oil viscosity between piston and cylinder in reciprocating systems such as compressors, presses and pumps with crank and slider driver without oil ring or ringless pistons. Using the numerical and analytical approaches respectively for nonlinear and linear oil velocity profiles assumed between piston and cylinder, dissipated power caused by oil viscosity was calculated and results of these two approaches were compared to validate finite difference results. Finally, the effect of vertical or horizontal position of piston and cylinder were compared in the case of nonlinear oil velocity profile for different applications.
