Interference Recommendation for the Pump Sizing Process in Progressive Cavity Pumps using Graph Neural Networks

Abstract

Pump sizing is the process of dimensional matching an impeller and stator to provide a satisfactory performance test result and good service life during the operation of progressive cavity pumps. In this process, historical data analysis and dimensional monitoring are done manually, consuming a large number of man-hours and requiring a deep knowledge of progressive cavity pump behavior. This paper proposes the use of graph neural networks in the construction of a prototype to recommend interference during the pump sizing process in a progressive cavity pump. For this, data from different expert applications were used in addition to individual control excel spreadsheets to build the database used in the prototype. From the pre-processed data, complex network techniques and the betweenness centrality metric were used to calculate the degree of importance of each order confirmation, as well as to calculate the dimensionality of the rotors. Using the proposed model a mean squared error of 0.28 was obtained for the cases where there were recommendations for order confirmations. Based on the results obtained, it was realized that there is a similarity with the dimensional defined by design engineers during the pump sizing process and this approach can be used to validate the project definitions.
