摘要 |
<p>Exemplary embodiments provide a progressive cavity pump or motor including a stator having a longitudinal bore and a rotor rotatably disposed within the longitudinal bore of the stator. The rotor includes a rotor core and a resilient outer layer formed of a resilient material bonded onto the outer surface of the rotor core. The resilient outer layer sealably connects the helical configurations on the outer surfaces of the rotor and the stator as the rotor rotates within the longitudinal bore of the stator.</p> |
