The Comparison between Swing-constrain Reciprocating Piston oil-free Air Compressor and Traditional Compressor

摘要

This paper gives the comparison of structure and motion characteristics between the new swing-constrain reciprocating piston oil-free air compressor (new compressor) and traditional compressor through mechanism, kinematics and dynamics analysis. By comparison, the new compressor has more parts, more manufacturing and maintenance costs and less machine height that is benefit to reduce storage and transportation cost. Furthermore, reversing knocking strength between piston and cylinder is released, friction loss is decreased dramatically between seal ring and cylinder and so the service time of seal ring is prolonged.
