G1100201 Reaction force and sealing characteristics of reciprocating compressor piston-cylinder system

Abstract

In order to improve vibration characteristics of reciprocating compressor with labyrinth piston, we investigate reaction force and sealing characteristics of piston-cylinder system using modeled experimental equipment. As supply pressure increases, stiffness, damping and flow rate increase in all case. As clearance between the piston and the cylinder decreases, stiffness and damping increase and flow rate decreases in all case. The stiffness and the damping of system with labyrinth piston is smaller than those with plane piston which has no labyrinth. On the other hand, leakage of labyrinth piston system is smaller than that of plane piston system.
