Abstract

PURPOSE: To enable a keeping of normal pumping operation irrespective of a volume of incoming liquid in a combined jet pump and electric pump.
CONSTITUTION: Discharge port 2 and intake port 3 of the electric pump 1 are connected in a loop by the circulation passages 4 and 5, and a jet pump 6 of an ejector construction is arranged in the circulation passages 4 and 5. An incoming passage 7 is arranged to communicate with a suction chamber between a nozzle of the jet pump 6 and the throat, and a pumping passage 8 is brached from the circulation passage 4, A valve 9 is arranged in the pumping passage 8 and the valve may be opened or closed by the driving means 10. Pressure detector means 11 and 12 are arranged of before the intake port of the circulation passage 5 and the flow-in passage 7, said driving means 10 is controlled by a valve control means 13 in reference to an electrical signal, said valve 9 is operated such that a pressure at the intake port 3 of the electric pump 1 is higher by a desired valve than that found in the incoming parrage 7.
