Modeling of the reed valves in reciprocating compressors and investigation of their dynamics characteristics

Abstract EN

In order to study the dynamics characteristics of the reed valve in reciprocating compressor, a new model based on energy conservation and Newton’s second law of motion was developed in this study.

In this new model, the structural parameters of the reed valve and the gas damping force are considered.

Moreover, an experimental system of reciprocating compressor was established to measure the actual movements of the reed valve and evaluate the validity of the model.

The simulation was implemented in a MATLAB environment for an efficient numerical solution and result presentation.

The experimental results are consistent with the numerical simulation results, which show that the theoretical model proposed is effective and accurate.

Furthermore, this study also used such model to analyze the effect of the structural parameters on dynamic characteristics.

In practice, this paper can provide a beneficial reference for the optimization design of the reed valve.
