| Abstract: |
| Progressive cavity pump (PCP) is a kind of devices extensively used in oilfield production. However, PCP is embedded deeply underground and tightly sealed in the oil well, so experimental measurement for temperature distribution and inner cavity outline change caused by temperature distribution in the stator is unpractical. In present paper, the mechanism of temperature change in stator is studied with the finite element simulation in order to analyze the coupled thermo-mechanical effect on stator. A one direction decoupling solution strategy is proposed for determining temperature distribution and corresponding structural response in the stator of the PCP. The influences of interference between the stator and rotor as well as rotating speed of rotor on temperature distribution and the change of stator’s inner cavity outline are discussed. |
