Optimisation de la conception de soupape à lamelles multiples d’un compresseur basée sur la conception axiomatique.

The reed-type valve is a key component of reciprocating compressors affecting the efficiency and reliability of compressors. The convention design of such valve components focused on the study of the individual elements of the system, which loses the opportunity of reaching the global optima. This paper proposes a scientific guide for the system design, based on which the reed valve system was optimized, in which the reed, the plate, the orifice and valve stop were analyzed systematically, design conflict of valve lift and valve life were indentified in the early design stage. In order to decouple the conflict, the valve lift was formulated into standard parameters. Finally, the design process was simplified. All the design parameters gear to each other. An industrial case is introduced to demonstrate the feasibility of the proposed design approach.
