Dynamic performance of suction valve in stepless capacity regulation system for large-scale reciprocating compressor

- A mathematical model coupled with compressor, actuator and hydraulic system is built.
- The dynamic performance of suction valve influenced by structural and operating parameters is detailed and analyzed.
- The p-V diagram and power consumption in the regulation condition are tested.
- The power consumption decreases 21% when the capacity is 70% of the full load based on the experiment.
