Numerical Simulation and Comparison on the Inner-Flow Field in Hydraulic Feedback Pump

Article Preview

Abstract:

Existing hydraulic feedback pump from the structure type can be divided into three kinds, big on the small,small on the big,big up and down. This paper focuses on the inner-flow field of three structural pumps about oil import and export of analyzing and comparing the velocity field and pressure field, chooses more suitable for hollow sucker rod oil production of hydraulic feedback pump.
