The Design of Compressor Valve to Consider the Flexibility and Reliability

This paper presents a qualitative introduction to the compressor valve design and development efforts by considered flexibility and reliability. Flexibility that is related to compressor efficiency and structural reliability are two main important factors in compressor valve design. In this study, we have designed the optimal CO2 compressor valve considered these factors. To obtain optimal valve flexibility we performed to system simulation of compressor. From this simulation, we could get some important data at valve design like the optimal natural frequency and the height of retainer. For each case bending stress, contact stress and natural frequency were obtained by finite element analysis. Also we studied the fatigue stability to obtain optimal valve shape that ensured to reliability.
