TEST METHOD OF SEALED MULTISTAGE CENTRIFUGAL ELECTRIC PUMP Russian patent published in 2025 - IPC F04B51/00 F04D13/06 F04D29/41 

FIELD: cosmonautics.

SUBSTANCE: invention relates to space engineering and is intended for use in designing thermal control systems (TCS), for example, telecommunication spacecraft (SC). Method of testing sealed multistage centrifugal electric pump of spacecraft thermal control system includes performance tests with control of operating parameters, wherein in process of tests the electric pump unit is installed on the test bench vertically during the same period of time of tests with the longitudinal axis of the electric motor rotor with centrifugal wheels installed on its shaft, providing the outlet from the electric pump from above, and the output to the electric pump from below, then it is installed vice versa.

EFFECT: high degree of reliability of proving the ability of EPU to operate without failure for not less than the required duration of operation in space conditions of weightlessness by tests for resource in ground conditions.
