The Electrical Submersible Pumping (ESP) system is one of the most commonly used artificial lift methods in petroleum industry and recent breakthrough this enclosed a capsule positioned on seabed skid. As it technology, with only small amount equipment currently operation, there clear need for greater understanding flow within geometry objective perfecting design promising submarine boosting sy...

Water is an essential element of life. The government of Ethiopia in collaboration with development allies’ attempts to increase pure water supply. Even though the coverage boosted dramatically still there is critical challenges in maximizing equipment’s reliability, improving service quality, maximizing capacity utilization, minimizing life cycle costs of water production mach...

This paper studies a superconducting maglev submersible cryogenic liquid pump (CLP) using magnetic bearing (SMB). A new structure is proposed for the self-stability of high-temperature levitation, and compact disk motor-pump. The rotor axial-flux motor connected with centrifugal impeller to form an impeller-rotor CLP. Supported by SMB system, rotates frictionlessly self-stabilisation as suspens...

In order to study the transient characteristics of submersible tubular pump in process power failure, 6DOF model was used carry out three unsteady numerical values for whole flow channel pump. The results show that calculation based on fourth-order multi-point Adams–Moulton formula are better agreement with experimental than first-order format predict impeller motion. When unit is powered off, ...
