Study of the Impact of Wear of Movable Interfaces on Failures of an Immersible Electrically Operated Vane Pump for Oil Extraction

Abstract

This article considers the conditions for wear-induced operating and parametric failure of electrically operated vane pump installations for oil extraction. It is shown that the wear of radial interfaces intensifies the vibration of the installation body by 10 to 15 times. It is found that the amount of leakage through radial seals of different radial stages hardly depends on the capacity of these stages. It is recommended to use wearproof bearings and reduce axial interface gaps.
