    Abstract: A control system for maintaining the product of the lifting pressure and lifting volume times flow constant in an adjustable pump having a regulating member acted upon by two pressure-controlled pistons. The device includes a control valve which is operatively connected with a spring with a linear characteristic, which spring is through the control valve operatively connected to an adjusting lever having an arm which is varied proportionally to the working pressure of the pump. The moment is produced by the force of that spring and that variable lever arm. A counter moment is generated by a force of a second spring and a second arm of the adjusting lever. Upon creating the force equilibrium on the adjusting lever the control valve is so controlled that the product of the pumping pressure and pumping volume times flow remains constant. The control valve controls one of the two pressure-controlled pistons which adjusts the stroke of the regulating member.

    Abstract: An adjustable main pump whose output volume is controlled by a servomotor operated by an auxilliary pump controlled by control valves, is provided with pressure regulating cylinder and piston means receiving fluid from the auxilliary pump and supplying fluid to the servomotor through the control valves. A pressure responsive piston is controlled by high pressure fluid from the outlet of the adjustable main pump, and acts on the regulating piston, forming a variable throttle therewith for controlling the flow from the regulating cylinder to a low pressure discharge conduit, or to the servomotor, depending on the pressure exerted by the pressure responsive piston on the regulating piston, so that the product of pump pressure and pumped volume, representing the power output of the main pump, remains constant during regulating movement of the pressure responsive piston.

In an embodiment, a method of operating a fleet 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 all 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 units at Maximum Intermittent Power (MIP) level to meet the demand HHP signal.

    Abstract: To provide a hybrid type or battery type working machine which hardly gives a feeling of strangeness on an operation to an operator and in which electric power stored in a storage battery can be used effectively within an operation scheduled time set in advance.An amount of reduction in the amount of electricity stored in an electric storage device 60 in a predetermined time t1 after an working machine starts up is obtained, and an operation possible time t2 is obtained from the obtained amount of reduction and a residual amount of the electricity stored in the electric storage device 60. Further, determination is made as to whether the obtained operation possible time t2 reaches a remaining time of an operation scheduled time obtained by subtracting a currently spent real operation time from the operation schedule time set in advance. When determination is made that the operation possible time t2 does not reach the remaining time of the operation schedule time, a pump absorption horsepower maximum value is reduced to such a value that the operation possible time can reach the remaining time of the operation scheduled time.

    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: The invention relates to a total power regulation device for two pumps (2, 42), each of which is connected to a working conduit (5, 45). The delivery volume of the pumps (2, 42) can be set separately by a respective adjusting device (6, 46), whereby a control pressure that is active in each adjusting device (6, 46) can be set by a total power regulation valve (18, 58). The latter (18, 58) has a measuring surface (24, 64) of the total power regulation valve (18, 58) of one pump (2, 42) can be directly exposed to the working pressure of the other pump (42, 2).
