Abstract: Methods and apparatus are provided for lubricating a piston-to-shoe interface in a hydraulic motor or pump. Piston assemblies are installed in a housing that are each adapted to receive a reciprocating drive force and are each configured, in response thereto, to cyclically move between an intake direction and a discharge direction. Each piston assembly includes a piston and a piston shoe, and the piston, the piston shoe, or both have a plurality of pockets formed in a surface that defines a piston-to-shoe interface. When the pistons cyclically move, liquid is supplied to each piston-to-shoe interface to form a hydrostatic bearing at each piston-to-shoe interface. A portion of the liquid that is supplied to each piston-to-shoe interface is selectively supplied to and from one or more of the plurality of pockets.

Abstract: Power and control logic configurations for gas well dewatering systems are provided. In one example, a reservoir is configured to contain hydraulic, lubricating fluid. An electric motor is configured to receive fluid from the reservoir for lubrication and a hydraulic pump powered by the electric motor is configured to receive fluid from the reservoir and pump the fluid into a hydraulic circuit. A positive displacement oscillating pump is powered by the hydraulic pump and configured to pump fluid from the reservoir to an outlet from the well. The electric motor and hydraulic pump receive the same fluid from the reservoir for lubrication and to create pressure in the hydraulic circuit, respectively. A switching device is connected to the hydraulic circuit and is switchable between a first position wherein fluid pressure from the hydraulic pump causes the piston pump to move in a first direction and a second position wherein fluid pressure from the hydraulic pump causes the piston pump to move in a second direction.

Abstract: The invention relates to a high-pressure cleaning appliance with a motor-pump unit, comprising a pump head on which is positioned a piston subassembly, which carries a drive motor with the interposition of a planetary gearing, and has a plurality of pistons which can be moved back and forth in the longitudinal direction of the motor-pump unit and each penetrate into a pumping chamber of the pump head, and also comprising a swash-plate unit which interacts with the pistons, the planetary gearing having a sun gear which is connected in a rotationally fixed manner to the motor shaft of the drive motor and is coupled to a ring gear via planet gears rotatably mounted on a planet gear carrier, the planet gear carrier being connected in a rotationally fixed manner to the swash-plate unit. In order for it to be possible for the planetary gearing to be lubricated to good effect even when the motor-pump unit is oriented substantially vertically, it is proposed for the piston subassembly to have an oil sump into which penetrates an oil-delivery tube which is aligned coaxially with the motor shaft and is connected in a rotationally fixed manner to the planet gear carrier, it being possible for oil to be fed to the planetary gearing from the oil sump via the oil-delivery tube.

Abstract: A circulating lubrication system for a centrifugal pump, or other rotating equipment utilizing an oil sump, is disclosed. The lubrication system includes an external reservoir located distant from the main lubrication chamber, so that lubricating fluid from the main misting chamber is forced out of the main chamber, cooled and cleaned (i.e. filtered) in the external reservoir, and thereafter fed back into the main lubricating chamber. In such a manner, the lubrication system maintains substantially clean, cool, and moisture free lubricating fluid in the main misting chamber and reduces the required downtime of the device. Thus, the life span of the device is lengthened while at the same time production is increased.
