Review on stator rubber of progressive cavity pump for oil extraction
Progressive cavity pumps for oil extraction exhibit outstanding advantages in the extraction of high viscosity,high sand content crude oil.The working principle and environment of pumps determine the service life of the rubber stator,which is the core component and pivotal to this equipment.Enhancing the wearing and swelling resistance of stator rubber material of the progressive cavity pump is of great significance.This paper first introduces the core components and the oil extraction principle of progressive cavity pumps.Secondly,focusing on the practical requirements for the stator rubber in progressive cavity pumps,the primary research findings of domestic and international scholars regarding key properties like aging,swelling and friction of stator rubber materials are reviewed.Furthermore,with reference to the emerging multiscale methods for material research in recent years,this paper provides an overview of concepts,principles,methodologies and their applications in mechanics and tribological properties of stator rubber.Finally,the prospects of future methods and research approaches aimed at continuously enhancing the wearing and swelling resistance of stator rubber in progressive cavity pumps for the extraction of crude oil are outlooked.
