PUMPING SYSTEM.
Application filed April 16, 1924. Serial No. 706,798..
This invention relates essentially to improvements in pump mechanism 1n which hydraulic pressure is employed.
lnoadly and generally my invention contemplates the provision of pump mechanism adapted to propel fluids that is `operated by means of a reciprocating column of a rela- 4tively inelastic or non-con1pressible fluid, such as Water, and in practicing the invention a reciprocating element or other fluidimpelling means is provided with actuating mechanism that iS operated by means of a moving column of liquid.
'Ihe invention is particularly adapted for carrying on pumping operations wherein the pump or fluid-impelling element is located at a distance from the prime mover. The invention thus has a special field of usefulness in the pumping of deep wells, such for example as oil and gas wells. In deep well pumping considerablel ditliculty is occasioned by the wear of the usual sucker rod equ1pment employed. Moreover, pneumatic pressure or air lift systems cannot be employed to the best advantage, especially in the deeper wells, on account of the distance between the liquid to be raised and the pump or compressor at the surface of the ground, since there is considerable loss in eilieiency due tothe elasticity or compressibility of the air or other gas employed. In accordance with my invention these difficulties are suc- `cessully overcome.
In the preferred embodiment of the invention a pump piston mounted in a suitable chamber and arranged to impel the fluid to be raised or pumped is in operative connection with another piston which is actuated by the reciprocatin movement of a column or columns of liquid, which 1i uid is impelled by a third piston operated y any suitable prime mover.
A special feature of the invention consists -in so disposing the pump piston and its co-related elements that this piston will operate on 'both the forward and backward stroke in impelling the fluid to be pumped.
The invention has particular reference to certain novel features of construction and arrangement of parts an example of which is given in this specification and illustrated in the accompanying-drawing which shows a diagrammatic sectional elevation of an aplable communication therewith is a paratus constructed .in accordance with the invention and constituting an embodiment thereof.
In the specific example of the invention thus illustrated the invention is shown as applied to the pumping of an oil well. Thus the conduit 10, through which the oil is brought to the surface, may comprise one oi" the regular well casings employed in oil Wells and is shown as extending down into an oil bearing strata indicated at 11. Positloned interiorly of the casing 10 or in suit- Pump chamber or cylinder 12 within which works a plunger or piston 13. In the arrangement illustrated the pump cylinder 12 is provided with a pair of inlet pipes 14 and 15 having check valves 16 and 17. The intake lines pass through Ithe closed bottom of the casing 10 and communicate with an inlet chamber which may be provided with a strainer 19 through which the oil enters. The pump cylinder is also provided with outlet lines 2O and 21 having therein check valves 22 and 23. It will be observed thatl there is an outlet and inlet on each side of the piston 13 and that the piston operates to propel fluid on both the upward and vdownward stroke.
The piston 13 is arranged to be actuated by suitable hydraulic pressure-o rated means. Thus the piston 13 is place in operative connection with a piston 24 by mounted on a piston rod 25 which is common to both pistons. The piston 21 operates in a cylinder or chamber 26 which is provided with suitable lpipes 27 and 28 for supplying the actuating liquid, the pipes as illustrated being connected to the opposite sides of the chamber. Various modifications of the means of actuating the piston 13 by hydraulic pressure exerted outside of the cylmder 12 may be employed. Thus, for example, the piston 13 may be mounted on a piston rod common to two other plungers positioned in separate cylinders, a hydraulic pressure line extending to each of these cylinders. It is preferable, however, to rovide a single cylinder as 26 andto a mit the hydraulic pressure fluid through two pipes terminating at opposite ends of the cylinder. The actuating cylinder 26 may well have a smaller piston displacement thanl that of the pump cylinder 12 since in operbeing 36 extend to pipes operated by ation thehydraulic pressure inl this cylinder is 'ir excess of the pressure in the pump cylinder. I
The pipes 27 and 28-which are adapted to sustain a column of. liquid for operating thepiston 24 extend upwardly to the surface and terminate in a cylinder 29, the pipes lcommunicating with opposite ends of the cylinder. Within the cylinder 1s a piston 30 mounted on a piston rod 31 which is connected by means of a connecting rod or crank shaft 32 to a suitable prime mover indicated at 33. l
34 represents a tank or reservoir for the water or other liquid that is employed in the pumping operation. Supply pipes 35 and 37 and 38, respectively, which communicate, respectively, with pipes 27 and 28. In starting the pumping operation, if pipes 27 and 28 are not filled with liquid, the piston 30 may be operated and thus the liquid is drawn into these pipes from the reservoir 34. After the ump is thus primed the liquid is admitted rom the reservoir 34 as may be required duel to any losses in the volume of liquid in the pipes 27' and 28. Check valves 39 and 40 are provided to prevent the backlow of liquid into the reservoir 34. Itis apparent that when the piston 30 in cylinder 29 is operated the double column of liquid in the pipes 28 and 27 operates to reci rocate the piston 24 and thus actuate the piston 13` in the pump cylinder 12.
It is desirable to have cushioning means to reduce or absorb the force vexerted by .the reciprocating column of liquid at the end of the strokes thereof. Thus air chambers 41 and 42 are provided and are adapted to be placed in communication with the pipes 28 and 27, respectively, (or with their branch lines 38 and 37) by means of valves l43 and 44, respectively. Suitable means Jfor timing the valves in synchronism with the movement of the liquid column is provided, such for example as dogs 45 and 46 adjustable trips 47 and '48 mounted on the piston rod 31. The trips 47 and 48 are so adjusted that the valves will be opened shortly before the piston 30 reaches the end o its stroke thereby permit- `to the pump ranged to conduct iiuid from the pump cylting the liquid under pressure to be released agalnst the air cushions in the chambers 41 and 42. Pressure relief valves 49 and 50 may be provided. V
' The ipes 37 and 38 are shown equipped with valves 51 and 52 for the purpose of admitting additional airv to the system. It should be noted that in practice the pipes 37 and 38 should enter the c linder 29 at the upper portion thereof and the valves 43 and 44 should preferably above that of the cylinder 295 the lines 27 and 28 have been shown entering the lower part of the cylinder 29 and the valves shown below the cylinder, because for pur oses of illustration it was convenient to in icate the complete assembly in this manner.
The conduit or casing 10 is provided with an outlet pipe 53 and it is apparent that when the pump piston 13 is operated liquid will be drawn 1n from the reservoir 18, raised through the conduit or casing 10 and thus discharged through the outlet 53.
Apparatus of preferred form andconstruction has been illustrated and described for the purpose of showing a way in which this invention may be used, but the'inventive thought upon which the application is based vis broader than theillustrative embodiment thereof, and I therefore intend'no limitations other than those imposed by the appended claim.
What I claim is:
An apparatus for raising Huid in wells,
i a conduit extending into the well, a pump cylinder disposed in said conduit, an inlet pipe adapted to conduct the fluid to be raised cylinder, an outlet pipe arinder to said conduit, an actuating cylinder disposed in said conduit, pistons in said cylinders and a piston rod connecting said pistons, a pair 'of pipes extending within saidv conduit and terminating at opposite ends of the actuating cylinder to thereby deliver the actuating fluid thereto, and means for reciprocating the fluid in said pipes.
In witness whereof I have hereunto set my hand this 14th dayof March 1924.
