Performance Characteristics of a Liquid Helium Pump.
Abstract
Part A of this report presents performance data for a simple, preinduced, single stage, centrifugal liquid helium pump powered by a close-coupled submersible cryogenic induction motor. Data on pump efficiency and the motor efficiency are given, and the effects of decreasing the pump leakage loss and removing the preinducer were also investigated. Part B describes a study of the cavitation characteristics of the pump in liquid helium I. The net positive suction head at cavitation of the pump was extensively investigated, and found to be near zero; and effects of removing the inducer, changing the pump inlet geometry, and varying the hellium temperature were also determined.
