Abstract
A method for impregnating a stator of a progressive cavity assembly with nanoparticles. The assembly comprising a stator having an inner core formed on its inner surface, the inner core defining a groove. A primary rotor is disposed within the groove. In operation, the primary rotor is removed from the stator, and a plurality of nanoparticles are distributed throughout the groove. A work rotor is installed within the groove and rotated at a high rate so as to press the nanoparticles into the inner core. The work rotor is removed from the stator and the primary rotor is re-installed into the stator.
Claims15
A method, comprising:
- providing a stator comprising an inner surface and an inner core formed on the inner surface and defining a groove;
- removing a primary rotor from the groove;
- after removing the primary rotor from the groove, distributing a plurality of nanoparticles within the groove;
- after distributing the plurality of nanoparticles within the groove, installing a work rotor into the stator;
- and
- rotating the work rotor within the stator such that it presses the nanoparticles into the inner core of the stator.
A method of treating a tubular stator having an internal elastomeric substrate within the stator and wherein at least one helical groove is formed in the elastomeric substrate wherein the stator is part of a progressive cavity assembly that includes a mating primary rotor, and further comprising:
- removing the primary rotor from the assembly before distributing nanoparticles within the at least one groove;
- after the nanoparticles have been distributed within the at least one groove, inserting a secondary rotor, differently sized than the primary rotor, into the stator;
- and rotating the secondary rotor within the stator until the distributed nanoparticles coat the groove;
- and removing the secondary rotor from the stator after the at least one groove has been coated.
