PUMP DYNAMIC TEST STAND Russian patent published in 1999 - IPC

FIELD: testing facilities. SUBSTANCE: proposed test stand is designed for testing hydraulic machines such as submersible centrifugal multistage pumps with electric drive. In proposed stand pumping unit with electric motor are arranged by their lower part (electric motor and submersible pump intake strainer) inside cylindrical casing with blind bottom and sealing arrangement in upper part of casing, and pumping part of unit is connected through flexible hose with pressure pipeline of hydraulic system. Cylindrical casing is installed for movement in eyes of upper platform of vertical frame-stand providing required angles of inclination of pumping unit under test. EFFECT: enlarged functional capabilities of test equipment, especially when testing for influence of angle of tilting of submersible unit being operated in inclined wells, up to horizontal ones. 1 dwg
