... conditions is still not available. In order to study the deformation of PCP’s elastomer, a numerical simulation method, finite element analysis (FEA), has been successfully applied. In order to improve PCP’s working efficiency and life, a novel structure, in which the elastomer is covered over the rotor...

....) this program was unique in that it also assessed the performance of the same metallic PCP stator using two different PCP rotors, to mimic a rotor-swapping operation. Some of the challenges encountered during this test program including issues with the downhole completion, high levels of downhole vibration...

... Abstract A three-dimensional finite element model for Progressive Cavity Pump (PCP) is constructed. The steel stator is simplified as a rigid body and the deformation of the rubber rotor is considered in the model according to the characteristic of the stator and rotor materials. The laden...

... of the elastomer. It is known that a proper magnitude of interference of the contact pair between rotor and stator is necessary to ensure a proper contact status. An oversize of interference will induce too severe strain as well as too much resistance of torque moment. Nevertheless a deficient interference can...

... Abstract This paper presents the results of a field trial conducted in Saskatchewan, Canada to investigate drive string dynamics between conventional and continuous rod and the impact of interference fit between rotor and stator in progressing cavity pumps (PCP). In August 2009, a well...
