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 one-way valve includes an upstream portion, a movable element, a downstream portion, a bias and flow paths. The upstream portion includes an inlet and a first engaging portion about the inlet. The movable element includes a second engaging portion (engageable with the first engaging portion to impede reverse flow), openings and first bias-contacting portions. The downstream portion includes an outlet and second bias-contacting portions. The bias acts between the first bias-contacting portions and the second bias-contacting portions to urge the movable element against the valve seat and surrounds an interior open to the outlet. The flow paths are via the openings and from outside of the first engaging portion and to the interior, and passing inboard of an upstream end of the bias.

摘要： A pump including one or more pumping chambers, one or more drive mechanisms for driving the one or more pumping chambers and a logic arrangement. The first pumping chamber of the one or more pumping chambers has a first inlet check valve, a first outlet check valve and a first temperature sensor. The logic arrangement is configured to identify a leak by applying logic to at least resistance-data indicative of a resistance of the first pumping chamber to the driving and temperature-data at least based on output from the first temperature sensor.

摘要： A sealing system for sealing an annulus. The annulus is defined by a cylindrical interior and a cylindrical exterior within, and axially movable relative to, the cylindrical interior. The sealing system includes an inner seal (to surround and sealingly engage the cylindrical exterior), a seal support (to surround, and axially support, the inner seal), an outer seal (to surround the seal support and sealingly engage the seal support and the cylindrical interior), a first support ring (to sit behind an outer periphery of the outer seal), and a back stop (to surround the cylindrical exterior and axially support the seal support and the first ring).
