摘要： A well point pumping system including a series of well points installed in an area of the ground which is to be dewatered or dried out. This system and its apparatus include an enclosed tank which can be located closely adjacent the well points which are often in a dirty, wet and/or remote area which often has difficult access. Also, the dewatering areas may be located at different levels below the ground surface. Usually the apparatus is subjected to severe abuse from handling, being moved about or from other machinery in the area. Furthermore, it may be difficult to install or remove the apparatus. The present system and apparatus include an enclosed tank which is capable of withstanding abuse and which can be located in the dirty working area and remotely from its power source. The tank encloses an impeller type water pump assembly, and also encloses a vacuum pump and its drive motor which create the required vacuum in the tank to cause water to be inducted into the tank from the well points. The pump assembly within tank is disposed with its axis in a vertical direction with the pump eye opening upwardly so that water can flow by gravity into the pump eye. The pump assembly includes an impeller, its shaft, a fluid motor attached to and for driving the shaft and impeller, and a mounting plate for enabling the entire pump assembly to be removed from the tank as a unit. The assembly does not require any close tolerances or adjustments for its installation. A control valve is provided for turning the vacuum pump on or off and for also regulating the speed of the pump, the valve being actuated by a water level float control in the tank. The power source for the system and apparatus can be located geographically remotely from the tank and away from the dirty working area where it is not subjected to abuse.

摘要： A submersible pump assembly having a volute casing in which a pump impeller is rotatably driven from a power source located outside the pump casing. The scroll-type casing has an axially directed inlet and tangential outlet. A drive shaft connects the power source with the radial flow impeller and a support bearing for the drive shaft is located at one side and centrally of the casing. The water inlet for the pump casing is located co-axially with the axis of the impeller at one side of the pump casing. The water flowing in an axial direction into the pump casing forms a vortex around the shaft bearing to create a minimum pressure zone around the bearing.

摘要： A hydraulic fan drive includes a hydraulic pump that has an adjustable swept volume. The hydraulic pump is assigned a pressure control valve arrangement that is configured to regulate a pump pressure by adjustment of the swept volume. The drive further includes a hydraulic motor configured to drive an impeller wheel and a pressure line, which is connected to a pressure input of the hydraulic motor and into which pressure medium is configured to be conveyed by the hydraulic pump. A hydraulic accumulator is connected to the pressure line and the displacement of the hydraulic motor is configured to be adjusted. Energy is buffer-stored by the hydraulic accumulator by feeding in pressure medium beyond the amount that is displaced by the hydraulic motor. This stored energy becomes free for other operations of a machine, for example, to which the drive is attached.
