摘要： A lift apparatus and method for driving a downhole reciprocating pump is disclosed. The apparatus includes a hydraulic cylinder having a piston and a hydraulic fluid port, the piston being coupled to a rod for driving the reciprocating pump, the piston being moveable between first and second ends of the cylinder in response to a flow of hydraulic fluid through the hydraulic fluid port. The apparatus also includes a variable displacement hydraulic pump coupled to receive a substantially constant rotational drive from a prime mover for operating the hydraulic pump, the hydraulic pump having an outlet and being responsive to a displacement control signal to draw hydraulic fluid from a reservoir and to produce a controlled flow of hydraulic fluid at the outlet. The apparatus also includes a hydraulic fluid line connected to deliver hydraulic fluid from the outlet of the hydraulic pump through the hydraulic fluid port to the cylinder for causing the piston to move through an upstroke away from the first end and toward the second end of the cylinder. The apparatus further includes a valve connected between the hydraulic fluid port and the reservoir, the valve being responsive to a valve control signal for controlling discharge of hydraulic fluid from the hydraulic fluid port of the cylinder back to the reservoir to facilitate movement of the piston through a downstroke away from the second end toward the first end of the cylinder. The valve is operable to prevent flow of hydraulic fluid through the valve during the upstroke and the hydraulic pump is operable to prevent flow of hydraulic fluid back into the outlet of the hydraulic pump during the downstroke.

摘要： A hydraulic piston pump includes a piston disposed in a blind housing bore of a piston housing and that reciprocates to generate a pumping action. To accommodate the piston, a piston cartridge is installed in each of the housing bores. The piston cartridge includes a piston sleeve having an inner sleeve periphery, a first outer sleeve periphery, and a second outer sleeve periphery. The inner sleeve periphery is configured to establish sliding contact with the piston. The first outer sleeve periphery has a first outer sleeve diameter that is larger than a second outer sleeve diameter associated with the second outer sleeve periphery. To seal against the blind housing bore, a liner cap having a cylindrical liner wall and an axial liner cover is disposed over the first outer sleeve periphery. The axial liner cover abuts a housing bore ceiling of the blind housing bore and can receive hydraulic fluid there through.

摘要： A pumping device may include a pump housing partially delimiting a working chamber, and a piston arranged therein, axially movable between first and second positions in which the working chamber has maximum and minimum volumes, respectively. The pumping device may include first and second fluid lines for introducing and discharging fluid to/from the working chamber, respectively. The first fluid line may be an annular fluid channel, fluidically connected to the working chamber via a breakthrough formed in the pump housing at an end face of the working chamber opposite the piston, running transversely to the axial direction at least in the area of the breakthrough. The second fluid line may open obliquely into the working chamber in an area of the second position, relative to the axial direction in an end face delimiting the working chamber towards the first fluid line. The pumping device may include first and second valves for fluid-tight closures of the first and second fluid lines, respectively, the second valve communicating fluidically with the working chamber directly.

摘要： The present invention provides a roundel structure for five-compressing-chamber diaphragm pump. The eccentric roundel structure is a cylindrical eccentric roundel in an eccentric roundel mount. The cylindrical eccentric roundel basically comprises an annular positioning dent, a vertical flank and a sloped top ring created from the annular positioning dent to the vertical flank. By means of the sloped top ring, the oblique pull and squeezing phenomena of high frequency incurred in a conventional tubular eccentric roundel are completely eliminated. Thus, not only the durability of the five-compressing-chamber diaphragm pump for sustaining the pumping action of high frequency from the cylindrical eccentric roundels is mainly enhanced but also the service lifespan of the five-compressing-chamber diaphragm pump is exceedingly prolonged.

摘要： A fluid pump assembly comprising a driven cam and a reciprocating member reciprocal within a bore provided in a pump housing as the cam is driven, in use, to cause pressurisation of fluid within a pump chamber. The pump assembly further comprises an interface between the cam and the reciprocating member, for example in the form of bevelled surfaces of the cam and the reciprocating member, which serve to drive the reciprocating member (i) to translate in a first, axial direction within the bore and (ii) to rotate within the bore in a second, rotational direction. An optional feature of the fluid pump assembly is that the pump housing defines a bearing for the cam which is provided with a recess to define a region of weakness to allow the bearing to deflect, in use, thereby to provide an increased lubrication volume between the cam and the bearing. The reciprocating member may take the form of a tappet which cooperates with a pumping plunger to pressurise fluid within the pump chamber.

摘要： Positive displacement vacuum pump is provided with a pump body, and a piston is positioned in the pump body with the piston being mounted for actuation by alternative linear movement. An elastic element biases the piston in a first direction, and a cam acts on a first end of the piston, with the cam being rotatably movable along an axis that is coaxial with the longitudinal axis of the piston to drive the piston in an alternating linear movement. A transverse bar is positioned between a first end of the piston and the cam, and the transverse bar is rotatably fixed but translationally guided in the direction of alternative linear movement of the piston. Additionally, the cam comprises a double surface to equally bias the transverse bar at two positions along the length of the bar.
