    Abstract: The invention relates to a method for controlling a hydrostatic drive having at least one first hydraulic consumer and one second hydraulic consumer. The two hydraulic consumers are driven by a common drive machine. First of all, a first power requirement of the first hydraulic consumer is determined (20). Proceeding from the determined first power requirement, the free power which is available as a result of the common drive machine is determined (21). This available free power of the common drive machine is scaled onto a possible actuating path of a control transmitter for the working hydraulics (22). A position of the control transmitter for actuating the second hydraulic consumer is determined (23) and a power requirement is assigned on the basis of the scaled available free power. An operating point of the common drive machine is fixed from the first power requirement and the second power requirement (24).

    Abstract: The invention relates to a method and to a device for operating an electric peristaltic hose pump, in particular a hose pump for transporting fluids in medical-technical devices, in particular extracorporeal blood treatment devices. In order to monitor the regular operation of a hose pump, the power consumption of the pump or a physical variable in correlation with the power consumption, in particular the pump flow, is monitored. The pump flow includes a periodically non-altering direct component which is superimposed on a periodically altering alternating component. In order to monitor the regular operation of the hose pump, the alternating component of the power consumption in relation to the direct component of the power consumption is monitored as whether it increases and/or decreases during blood treatment.

    Abstract: A method of controlling a hydraulic system having a variable displacement pump operatively coupled to an engine. The method includes detecting a speed of the engine, and determining a desired power value of the pump. The method also includes identifying an allowable power value that may be expended by the pump at the detected speed. The method also includes selecting a pump power value. The selected pump power value is the lower of the allowable power value and the desired power value. The method further includes adjusting the pump to deliver the selected pump power value.

    Abstract: A method of controlling a compressor in a transport temperature control unit having a prime mover providing power to the compressor. The compressor has a power requirement that varies depending on loading conditions. The method includes determining the maximum power available from the prime mover, determining the power requirement of the compressor, and adjusting the loading conditions of the compressor so that the power requirement of the compressor substantially equals the maximum power available from the prime mover. Preferably, the method includes starting the compressor at a low speed, varying the suction pressure as permitted by the maximum amount of power available until the suction pressure reaches a maximum suction pressure setting, and after the suction pressure reaches a maximum suction pressure setting, increasing the speed of the compressor as permitted by the maximum-amount of power available.

    Abstract: A control device for an axial piston machine in which the rocker controlling the angular orientation of the cylinder drum is shifted by a differential-action setting piston having a pin which engages in the rocker. The opposite end of this pin bears via a pressure body on one arm of a bell crank lever which can have a curved camming surface, the pressure body including a roller and being urged by a first spring against the bell crank lever. The other arm of the bell crank lever is engaged on one side by a control piston subjected to the pump pressure while the valve member which controls the pressure to the large-diameter side of the setting piston engages the opposite side of the bell crank lever and is urged against this opposite side by a second spring.

    Abstract: Embodiments of a system, controller, and method for operating a plurality of pumps for a turbine driven fracturing pump system used in hydraulic fracturing are disclosed. In an embodiment, a method of operating a plurality of pumps associated with a hydraulic fracturing system includes receiving a demand Hydraulic Horse Power (HHP) signal. The demand HHP signal may include the Horse Power (HP) required for the hydraulic fracturing system to operate and may include consideration for frictional and other losses. The method further includes operating available pump units at a percentage of rating below Maximum Continuous Power (MCP) level, based at least in part on the demand HHP signal. Furthermore, the method may include receiving a signal for loss of power from one or more pump units. The method further includes operating one or more units at MCP level and operating one or more pump units at Maximum Intermittent Power (MIP) level to meet the demand HHP signal.

    Abstract: A method for controlling a drive unit mechanically connected to a reciprocating linear-motion double-acting pump includes the use of speed-regulating control during the phase in which the piston is moving in just one direction, ascent (109) or descent (102), and the use of torque-regulating control immediately after the reversal (107, 114) of the direction of travel. The method is applicable to a control device and to a drive unit mechanically connected to a reciprocating linear-motion double-acting pump.
