  • Patent number: 10107274
    Abstract: An electrical submersible pump assembly for use in a well, including a well having a high gas-to-liquid ratio has a motor, a hollow, tubular drive shaft which drives the pump, and a liquid-gas separator assembly upstream of the pump intake. The liquid-gas separator has a hollow tubular portion, which communicates with the open, lower end of the drive shaft, openings through its sidewall, and a closed lower end. The sidewall also includes at least one outwardly extending projection shaped for urging liquid contained in a liquid/gas mixture flowing towards the pump outwardly, away from the sidewall openings. Preferably, the outwardly extending projection comprises a helical blade which, using either the well casing or a separate sheath, defines a helical channel through which the oil-gas mixture flows prior to reaching the pump intake.

  • Patent number: 10072654
    Abstract: An electroproportional pressure control valve of cartridge-type construction is screwed into a housing bore of a hydrostatic pump. The cartridge includes an adjusting pressure port, a pump port, and a tank port. The adjusting pressure port is relieved to the tank port in a normal position of a spring-biased valve plunger of the pressure control valve. A connection from the pump port to the adjusting pressure port is opened counter to the force of the spring by increasing a current of an electromagnet and increasing the pump pressure at the pump port. The spring, the electromagnet, and the resultant force of the pump pressure act along a common axis of movement of the valve plunger. A first nozzle connects the adjusting pressure port to an adjusting pressure chamber. A second nozzle connects the adjusting pressure port to the tank port.

  • Patent number: 10054124
    Abstract: A submersible, water circulation system for enclosed tanks such as used by municipalities, fire districts, and industries. The system includes a driving unit having a shell extending along an axis with a pump supported within the shell. The shell has at least one inlet and at least one outlet and is positionable on the floor of the tank with the outlet facing upwardly. The upwardly facing outlet is preferably a thin, upwardly facing, elongated slot and creates a thin, substantially planar discharge of water therethrough that is directed upwardly toward the surface of the body of water. The substantially planar discharge presents a very large surface area for its volume and induces water adjacent the outside of the shell of the driving unit to move upwardly with it toward the surface of the body of water.

  • Patent number: 10012218
    Abstract: A variable displacement compressor having means for regulating the minimum inclination angle of a swash plate, a spring urging the swash plate in the inclination angle-increasing direction, and a spring urging the swash plate in the inclination angle-decreasing direction. The swash plate inclination angle is ?a as the sum of the urging forces of both springs is zero, when the drive shaft is not rotated; and, when the drive shaft is rotated, its inclination angle is ?b at which the sum of moments MS, MF is zero. Moment MS of rotational motion is based on selling the product of inertia in the variable-angle direction of the swash plate to decrease the inclination angle of the swash plate from ?a. Moment MF is based on the combined urging force of both springs set so that the inclination angle ?b is positioned at a minimum angle at maximum rotational speed.
