摘要： A disc pump system includes a pump body having a substantially cylindrical shape defining a cavity for containing a fluid. The cavity having a resonant cavity frequency is formed by an internal sidewall and substantially closed at both ends by a first end wall and a driven end wall. The disc pump system includes an actuator that is driven a frequency (f) that corresponds to the fundamental resonant frequency of the actuator. The internal sidewall is configured to expand and contract in response to changes in temperature, thereby causing the actuator and cavity to have approximately the same resonant frequencies over a range of operating temperatures.

摘要： A two-cavity pump having a single valve in one cavity and a bidirectional valve in another cavity is disclosed. The pump has a side wall closed by two end walls for containing a fluid. An actuator is disposed between the two end walls and functions as a portion of a common end wall of the two cavities. The actuator causes an oscillatory motion of the common end walls to generate radial pressure oscillations of the fluid within both cavities. An isolator flexibly supports the actuator. The first cavity includes the single valve disposed in one of a first and second aperture in the end wall to enable fluid flow in one direction. The second cavity includes the bidirectional valve disposed in one of a third and fourth aperture in the end wall to enable fluid flow in both directions.

摘要： A method of unloading liquid from a reservoir includes deploying a pumping system into a wellbore to a location proximate the reservoir using a cable. The pumping system includes a motor, an isolation device, and a pump. The method further includes setting the isolation device, thereby rotationally fixing the pumping system to a tubular string disposed in the wellbore and isolating an inlet of the pump from an outlet of the pump; supplying a power signal from the surface to the motor via the cable, thereby operating the pump and lowering a liquid level in the tubular string to a level proximate the reservoir; unsetting the isolation device; and removing the pump assembly from the wellbore using the cable.

摘要： An apparatus and method are disclosed for inducing fluid flow. A fluid flow apparatus includes a directional membrane, a directional flow mechanism, and an oscillation module. The directional membrane allows a fluid to pass through the directional membrane in a first direction and resists fluid passing through the directional membrane in a second direction, the first direction substantially opposite the second direction. The directional flow mechanism allows a fluid to flow in a third direction and resists fluid flow in a fourth direction, the third direction substantially opposite the fourth direction. The oscillation module induces an oscillation in the directional membrane, wherein the oscillation of the directional membrane induces a flow of the fluid through the directional membrane in the first direction.
