چکیده

Based on the theoretical analysis and experimental study of pneumatic damping behaviour for the valves in the reciprocating compressor, this paper presents a simple mathematical model of pneumatic damping valves, in which the non-viscous damping force is introduced. The non-viscous damping coefficient is obtained by the experimental determination. The simulation results of this simple model for pneumatic damping valves are in good agreement with the experimental results.

Improved Dynamic Valve Analysis for Mass Damping and Moving Frame of Reference

This paper presents investigations of two special cases of dynamic valve analysis. These special cases arose in the development of a new type of gas field reciprocating compressor. These special cases were for a moving frame of reference (since the discharge valves were integral with the piston) , and for independent mass damping {sealing/damping elements are modelled separately instead of as "...

Parametric Study of Hermetic Reciprocating Compressor

A numerical simulation of the thermal and fluid-dynamic behaviour of hermetic reciprocating compressors has been developed by solving the one-dimensional and transient governing equations of the flow (continuity, momentum and energy) in the whole compressor domain. The governing equations are discretized using an implicit control-volume formulation. A SIMPLE-like algorithm, extended to compress...

Fuzzy gain scheduling of PID controller for stiction compensation in pneumatic control valve

Inherent nonlinearities like, deadband, stiction and hysteresis in control valves degenerate plant performance. Valve stiction standouts as a more widely recognized reason for poor execution in control loops. Measurement of valve stiction is essential to maintain scheduling. For industrial scenarios, loss of execution due to nonlinearity in control valves is an imperative issue that should be t...

Control of a pneumatic drive using electronic pressure valves

The primary task of the electronic pressure (E/P) valves is to control the pressure continuously in different industrial automation processes. Their use in pneumatic drives allows regulating pressures in both cylinder chambers and so it is possible to achieve a direct force controlled actuator. Additionally to the force control, position control of the pneumatic actuator using E/P valves has be...
