摘要： The object of the invention is to improve delivery of the multi-phase mixture, in particular hydrocarbons from a well, and to limit the free gas volume. According to the invention, this object is attained in that a partial liquid flow (13) is split off on the pressure side from the main delivery flow and guided to the high-pressure side of at least one ejector pump (2) arranged on the suction side as an auxiliary delivery device. The pump installation provides a feed line (7) connecting the pressure chamber of the displacement pump (1) with the high-pressure side of at least one ejector pump (2), whereby the ejector pump (2) is arranged on the suction side in the delivery direction of the displacement pump (1).

摘要： A recirculation system is disclosed for driving reactor coolant water contained in an annular downcomer defined between a reactor vessel and a reactor core spaced radially inwardly therefrom. The system includes a plurality of circumferentially spaced pumps disposed in the downcomer, each pump including an inlet for receiving coolant water from the downcomer as pump inlet flow, and an outlet for discharging the pressurized water. The recirculation system firstly increases the pressure of the pump inlet flow at the pump inlet before being sucked into the pump for being further pressurized by the pump.

摘要： A hydraulic fluid pump for aircraft turbine engine fuel delivery systems comprises a housing having a pump drive shaft mounted for rotation therewithin. A centrifugal pump stage includes an impeller coupled to the drive shaft and having a circumferential array of radially extending passages with inlet ends adjacent to the shaft and outlet ends at the periphery of the impeller. An inducer stage includes a spiral inducer coupled to the shaft to rotate coaxially with the impeller and having an outlet end adjacent to the inlet end of the impeller passages. An injector stage includes a passage in the housing for feeding fluid to the inlet end of the inducer, and a circumferential array of nozzle orifices in the housing aligned with the injector passage and receiving fluid from a collection cavity that surrounds the periphery of the impeller. The pump inlet is fed to the injector passage, with the injector nozzles cooperating with the passage to boost fluid pressure and flow through the passage to the inducer inlet, which in turn boosts fluid pressure and flow to the impeller.

摘要： A wellpoint system for removing fluid from the earth is disclosed comprising a motor driven centrifugal pump having a pump chamber divided into a suction chamber and a discharge chamber by a bulkhead. A discharge pipe extends from the discharge side of the pump through the suction chamber and into the discharge chamber. A venturi is provided in the discharge pipe in communication with the suction chamber so that a suction is created in the suction chamber as fluid passes through the discharge pipe into the discharge chamber. A plug valve is mounted in the bulkhead and is controlled by a float positioned in the suction chamber so that the lowering of the float will open the plug valve. A suction line extends from the wellpoint header system and is in communication with the suction chamber. A normally closed flap valve is provided on the suction line within the suction chamber to permit the pump chamber to be initially filled.
