Reciprocating compressors are commonly used machinery for industrial applications. Unscheduled downtime and maintenance activity on the compressors causes considerable loss in throughput and efficiency of a plant. Of all the failures that cause unscheduled downtime in reciprocating compressors, valve related causes are predominant. The objective of this paper is to research detection and prediction of valve failures by Multi-layer perceptron neural network, MLPANN, Radial basis function, RBFANN, and Group Method of Data Handling, GMDH analysis of pressure, temperature and vibration signals, which are the most common measurements on a reciprocating compressor system. These parameters are measured on a continuous basis and baselines are established for normal (or acceptable) behavior and failure (or fault) condition. In each model, the optimized structure is obtained through a Genetic algorithm, GA, technique. The results indicated no statistically significant differences among the three models. However, the MLPANN neural network demonstrated superior performance in fault diagnosis.
