Estimation and Prediction of the Parametric Reliability of Electro-Pneumatic Automation Products

Estimation and prediction of the parametric reliability of electro-pneumatic valves for complex gas industry automation systems on the basis of degradation failure are considered. The proposed technique is based on computational determination of the technical characteristics of electro-pneumatic valves and may be used to estimate and predict the parametric reliability of these devices in the case where it is not possible to establish the real values of the technical characteristics. Stages in the development of the technique are considered and problems involved in the estimation and prediction of the reliability of electro-pneumatic valves at different stages of their life cycle are presented.
