P16452 Active Reciprocating Compressor Valve Assembly System Review

Problem Statement Background and Current State Compressors have valves that are passive devices that work with a spring. These valves experience high plate impact velocities which causes fatigue failures Therefore valves have short operating life that leads to frequent replacement Problem Statement Design, build, and test an active compressor valve assembly Goals and Benefits Goal of this project is to design and build an active reciprocating compressor valve assembly that controls when to release air from the compressor Significant gains on efficiency and wear are possible if valves are actively controlled Demonstration will require instrumentation to prove the design is meeting reciprocating compressor like specifications. Constraints End result must budget $5,000 Shop air will be needed to provide pressure to the cylinder Labview must be used to collect relevant data
