摘要： An electric motor pump for corrosive, electric conductive, cryogenic and/or hazardous liquids which is submerged in the liquid, comprising a centrifugal pump in a pump housing and an electric motor in a separate motor housing, transmitting the power through a magnetic coupling, whereby a thrust equalizing device is mounted on the rotating pump shaft. The motor housing is connected to a tubular device and the power cable is inside the tubular device and on one end connected to the electric motor stator and on the other end to the electric power grid. The motor housing and the tubular device contain an inert fluid under higher pressure than the surrounding liquid. The electric motor pump is able to operate as a reverse running pump in the turbine mode, whereby the electric motor is an induction motor operating as an induction generator.

摘要： A safety pumping system including a pump (19) and an electric motor (15) is adapted to be immersed in a fluid (11) contained in a tank (10). The electric motor and the pump are interconnected by a driving shaft (23). The electric motor is enclosed in a motor housing, which defines an inner space (18). The motor housing is surrounded by an outer shell or jacket (14), which defines an outer space (17) between the outer shell and the motor housing. In order to reduce the risk of explosions when the pumping system is immersed in an inflammable liquid, protective gas, such as nitrogen, at a superatmospheric pressure is supplied to the inner space (18) of the motor housing (15). Protective gas is also supplied to the outer space (17) defined by the outer shell of jacket (14). The gas pressure within the inner space (18) preferably exceeds the gas pressure within the outer space (17), which preferably exceeds the atmospheric pressure. The two separate zones of protective gas substantially reduce the risk of explosions due to overheating or generation of electrical sparks.

摘要： Fluid transfer apparatus comprising a fluid reservoir and a pump connected to the reservoir by a supply line, wherein the apparatus is configured so that vapor generated in the pump during periods of inoperation may escape from the pump cavity through the pump inlet, rather than being trapped in the pump cavity, and liquid may flow into the pump cavity from the supply line through the pump inlet to replace escaping vapor, thereby providing reliable pump start-up during intermittent operation. The apparatus may be employed to pump LNG for fueling of vehicles. Where LNG or another cryogenic fluid is being pumped, the pump is preferably driven by a motor located above the pump and connected thereto by an elongated shaft. Shaft seals may be provided to prevent the fluid being pumped from contacting the motor or the bearings supporting the motor shaft. A vapor trap may be provided beneath the shaft seals to prevent contact between liquid being pumped and the shaft seals.

摘要： A method and means for providing a protective environment for submerged pumps are described. For a submerged water pump a shell or casing is installed to enclose at least a lower portion of the pump, and a protective fluid medium, typically compressed air, is introduced in the shell to exclude water from contacting the pump operating components or lines when the pump is not in use. Means are provided for quickly removing the protective medium and permitting water to enter the pump when it is desired to put the pump into operation.

摘要： A protection column is employed about a sump pump to exclude liquid and foreign matter in the sump from entering the pump interior until a time just prior to priming and activation of the pump. The column has a closed bottom portion serving as a vessel and permitting the column to float as the liquid level rises in the sump. The upper part of the column fits about the pump to act as a guide and has a series of vertical slots. The column floats until the bottom of the column strikes the bottom of the sump pump, which prevents the column from rising further. As the water level continues to rise in the sump, water enters the column through the slots, causing the column to sink to the bottom of the sump and permitting the liquid to rise to a level in the pump commensurate with the level elsewhere in the sump, thereby priming the pump.

摘要： A submersible pumping unit having a reversible pump driven directly by a rotary hydraulic motor. Bearings for the pump shaft are lubricated by hydraulic liquid from this motor and are capable of taking up end thrusts in either direction. A hose on the outside of the casing for the pump and motor is inflated by hydraulic liquid from the motor to expand radially outward into sealing engagement with a well casing. This pumping unit may be suspended underground to pump water either vertically or horizontally.
