摘要： A hydraulic circuit arrangement includes a plurality of electronically-commutated pumps providing flow to a common hydraulic line, the plurality of electronically-commutated pumps including one or more quantized electronically-commutated pumps and one or more unquantized electronically-commutated pumps. A controller includes a pressure controller and a flow divider. The pressure controller is configured to receive a pressure signal corresponding to the pressure within the common hydraulic line, to compare the pressure signal to a demanded pressure, and to determine a target flow value required to produce the demanded pressure. The flow divider is configured to receive the target flow value and allocate the target flow value into a quantized target flow value for allocation among the one or more quantized electronically-commutated pumps and an unquantized target flow value for allocation among the one or more unquantized electronically-commutated pumps.

摘要： A system and method for pumping fluid. The system includes a sequence of two or more positive-displacement sub-systems each having a respective one-way inlet. A respective one-way flow path links each adjacent two of the sub-systems. A one-way outlet from a last of the sub-systems is provided. The system is capable of a mode of operation in which at least some of the sub-systems are substantially in phase with respect to each other to cause the system to draw fluid from more than one of the one-way inlets; and another other mode of operation in which at least some of the sub-systems are substantially in antiphase with respect to each other to increment a pressure of the fluid as the fluid moves along the sequence.

摘要： A high pressure pump including a linear actuator having a servo motor to axially rotate a hollow rotor shaft in alternating directions, the servo motor having a stator positioned co-axially around the hollow rotor shaft with an interior of the rotor shaft being co-axially coupled to a drive member to convert axial rotation into reciprocal displacement, the drive member being constrained against linear movement and supporting a shaft. At least one piston is coupled to the shaft and the piston is arranged within a cylinder to define a pumping chamber, whereby alternating rotation of the rotor shaft causes reciprocal linear displacement of the piston to pressurize fluid in the pumping chamber. A drive mechanism includes a controller coupled to a servomotor and an encoder to measure movement of the hollow rotor or output shaft and send a feedback signal proportional to the movement to the controller.

摘要： A thick-matter pump for producing a continuous thick-matter flow is described. The pump includes at least two pump units, which alternate in pumping and suction operation, a suction line with a charge-pressure device, which acts separately from the pump units for actively bringing about a thick-matter compression, a delivery line, and a switchover device for switching between the pump units. In a first operating state for conveying the thick matter, by way of the switchover device, at least one first pump unit is connected during pumping operation to the delivery line and at least one second pump unit is connected during suction operation to the suction line. In a second operating state, by way of the switchover device, at least one first pump unit is connected during suction operation to the delivery line and at least one second pump unit is connected during pumping operation to the suction line, and the charge-pressure device is switched to an inactive state.

摘要： High pressure pump systems for use with waterjet systems and other systems are described herein. A pump system configured in accordance with a particular embodiment includes a first multi-cylinder pump having a first crankshaft and a second multi-cylinder pump having a second crankshaft. The first and second crankshafts are operably coupled together (via, e.g., a common drive system) so that the reciprocation cycles of the corresponding pistons or plungers are spaced apart from each other in equal intervals of crankshaft rotation.

摘要： When the fluid flow output of a synthetically commutated hydraulic pump is adapted to a given fluid flow demand, pulsations in the fluid output flow of the synthetically commutated hydraulic pump can occur. To avoid such pressure pulsations, it is suggested, to use a set of pre-calculated actuation patterns for actuating the electrically commutated valves of the synthetically commutated hydraulic pump.
