1Claim.
This invention relates to deep well pumps and more particularly to a drive means therefor and has for the primary object the provision of a hydraulic pump jack element driven by any suitable power and which will actuate the pump with a.
minimum loss of power and also will permit the power cylinder and piston thereof to be remotely located with respect to the well while the driven piston and cylinder thereof will be located in the well and in close proximity to the pump cylinder and the piston thereof -permitting a direct connection to be had between the piston of the pump y and the driven piston, the latter being valved -to permit equalization of the liquid on each side thereof during the operation of the device.
With these and other objects in view, this invention consists in certain novel features of construction, combination andarrangement of parts to be hereinafter more fully described and claimed. For a'complete understanding of our invention, reference is to be had to the following description and accompanying drawing, in which Figure 1l is a fragmentary vertical sectional view showing our invention associated with a well.
Figure 2 is a fragmentary vertical sectional view illustrating the valves of the driven piston.
, Referring in detail to the drawing, the numeral I indicates a pump cylinder adapted to be` located in a well adjacent Vthe Abottomthereoif and has reciprocally mounted therein a piston 2, the stem 3- of which extendsthrough a packing v gland I carried by a head 5 of the pump cylinder. a 'I'he pump cylinder also is provided with a head 3o 6. Connected to the heads 5 and 5 are standpipes 'I and 3 each including a combined stand valve and 'strainer- 9. The standpipes 1 and 8 being .connected to theopposite 'ends of the pump cylinder permits the latter to be double acting during the reciprocation of the piston 2.v Connectedl outletpipes I0 are connected with the heads I5l and 5 and lead out -of the Well, as shown in Figure l, and each has a vcheck valve II therein.
5 'I'he piston 2 is oi' the double cup type with a spacer therebetween, the-cups being reversely arranged. V-
The head 5 is oi' the double type for the purpose of connecting to the cylinder I a cylinder I2 and 5 y"permitting the piston stem 3 to enter said cylinder I2. Apiston I3 operates in'the'cylinder I2 and is connected to the pistonY stem 3. The cylinder 'I2 is locateddirectly above the `pump cylinder I and. the upper end is equipped with a 55 head. I 4. A fluid pipe I5 is connected to the head (ci. 10s-44) I4 and a iiuid pipe I6 is connected to thedouble head 5 and in communication with the lower end of the cylinder I2. The pipes I5 and I6 are connected to opposite ends of a powercylinder I1 remotely located with respect to the well and in which operates a power piston I8 constructed similar to the piston 2, the stem of which is indicated vby the character I9 and is extended outwardly of the power cylinder and adapted for connection with any suitable power source for imparting reciprocation to the piston I8. Th'e .cylinders I2, Il, and pipes Il i and I5 are completely i'llled with liquid which is non-compressible so that when the piston I8 is reciprocated by the power source (not shown) the piston I3 will be caused to reciprocate correspondingly. The reciprocation of the piston I3 drives the piston 2 in the pump cylinder causing the fluid of the well to be taken in said pump cylinderand expelled therefrom by way of the connected outlet pipes I0 to some receiving medium (not shown). Connected to the iluid pipes I5 and I6 are uid supply pipes 20 each having a control valve 2I and one having a bleed valve 22 and a A similar bleed valve 23 is connected to the 'pipe I5. The purpose of the bleed valves is to`permit air trapped in the system to be vbled when necessary for th'esuccessful operation of this invention. The heads on the cylinder I2 have abutments 24 and the piston I3 has passages therethrough controlled by oppostely arranged valves 25 normally held closed by springs 26. When the ,piston I9 reaches substantially the end of its stroke in-one direction one of the abutments unseats the valves, allowing liquid to pass through said piston I3 and when-the latter substantially completes its stroke in an opposite direction the. other valve is unseated by the other abutment, permitting liquid to pass through the piston I3. The valves act to maintain equal liquid pressure upon the opposite sides of the piston I3 Aand to compensatevfor variance in the distance traveled between the pistons I8 and I3, for instance, the piston I8 may have a longer vstroke than the piston I3, and if so the piston I3 will reach the end of its stroke prior to the piston I8 reaching the end of its stroke, there- 1 fore, one of the valves of the piston I3 will be opened by one of the abutmentsand allow liquid to pass through the piston I3 ywhile the piston I8 lis completing its stroke.
A device -of the character described will successfully operate a pump piston by a minimum amount of power and with a minimum loss ,of 'power due to friction. and will permit the power cylinder and piston as well as the power source .2` to be located remotely to the well and further will permit the pump cylinder and its piston to be successfully operated in wells of' various depths and also permits the driven piston to be connected directly to the pump piston with the cylinder' er piston operating in the power cylindenffluid pipes connecting the opposite ends of the power cylinder with opposite ends of the second named cylinder whereby movement of uid by the reciprocation ofthe power piston imparts reciprocation to the second named piston and the latter in turn reciprocates the pump piston, valved uid supplypipes connected to the pipes connecting said power cylinder with the second named cylinder, said piston of the second-named cylinder having passages therethrough, spring seated valves for controlling said passages, and abut- 'ments in` the second named cylinder to unseat said valves on the second named piston substantially reaching the ends of its strokes.
