This paper proposes a solution to the problem of improving the reliability of the operation of
progressive cavity pump units in deviated and directional wells. High dogleg severity …

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 …

The wear of the all-metal progressive cavity pump (AMPCP) has become one of the main
concerns from various field applications of oil production. This work systematically reveals …

Abstract Progressive Cavity Pump (PCP) is a common artificial lift method for high viscosity
liquid production. In elastomeric stator PCP, the clearance between the metal rotor and …

This contribution studies the impact of the rotor-stator interaction in a single-stage
progressing cavity pump on the flow rate and pressure. Specifically, we investigate the effect …

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 …

Functionally graded concrete (FGC) is a novel technology in the building industry, allowing
for savings of up to 50% mass in standard concrete elements like slabs and beams. This is …

Concrete pumping is a widespread technology used in on site construction around the
world. It also is a viable technology for the automized fabrication of concrete elements. This …

During the rice‐threshing process, straws always attached to a threshing cylinder and
induced vibration and modal variation. In this paper, the constraint and threshing modals of …

Automated fabrication of concrete elements requires precise control of outgoing volume
flow. Since measurements of the volume flow or the total extruded volume are challenging …
