This study aims to investigate wax deposition in progressive cavity pumps (PCP), which are
widely used in the oil industry. Wax buildup on the walls during extraction can significantly …

We present in this paper a comprehensive and universal tool/model for the mud motor
power section. The model includes performance, fatigue, and hysteresis heating simulation …

As the metallic stator progressing cavity pump (PCP) operates with the stator and rotor in
clearance fit, the slippage between cavities has a significant influence on the pump …

Computational fluid dynamics (CFD) simulations of multi-lobe progressive cavity (PC)
pumps are limited in the literature due to the geometric complexity of the pump, which places …

As a submersible pump, the progressive cavity pump is used to pump fluids from oil wells,
and plays a crucial role in determining the oil production. In order to improve the fluid …

A progressing cavity pump (PCP) is a positive displacement pump with an eccentric screw
movement, which is used as an artificial lift method in oil wells. Downhole PCP systems …

Existing multiphase pumps face challenges in transporting more than two phases, including
high costs and energy consumption. To address the challenges of multiphase transportation …

A Progressing Cavity Pump (PCP) works by forming a progressive seal cavity through the
eccentric rotation of rotor. PCP parameters, such as eccentricity ratio e/D, can influence its …

The stator and rotor of an all-metal screw pump are made of metal; so the matching method
of the all-metal screw pump cannot be like that of the traditional rubber screw pump, and a …

Traditional rubber screw pumps use an interference method to engage. When the pressure
is less than the breakdown pressure of the pump, there is no leakage in the pump. The all …
