PUlVlP FOR DEEP WELLS.
SPECIFICATION forming part of Letters PatentNo. 711,804, dated October 21, 1902.
Application led September 30, 1901. Serial No. 77,094. (No model.)
To all whom it may concern.-
where a sandy or heavy oil is to be raised. A
commercially successfulor practical pump for this purpose must be simple in construction, durable, comprised of parts easily assembled and readily replaceable, and be efflcient in operation. The pump herein presented embodies a structure fulfilling these requirements, and, in addition, it includes other features adding to its general efficiency.
It is well known that the diameter of a deep Well is comparatively small, and the valve mechanism and other operating parts of the pump herein presented have been arranged and fitted with special reference to this fact. It is also well recognized that the closer-the discharge -valve approaches the receiving- Valve on the downward stroke of the piston the greater the amount of fluid pumped, and the pump herein presented has been constructed with special reference to utilizing this principle to a maximum degree.
A further object sought to be obtained is to provide a pump which will remain at the bottom of the well during the working thereof; and another object is to provide meanslfor the oil circulation to prevent sand settling around the bottom of the pump and to provide a vent outside of the fluid-chamber for the escape of gas.
The invention further includes the details of construction to be hereinafter set forth, and particularly pointed out in the claims.
The invention is illustrated in the accompanying drawings, in which- Figure lis aside elevation of the lower portion of the pump. Fig. 2 is a longitudinal sectional view of the same. Fig. 3 is a detail of the cage of the inlet-valve. Fig. 4 is a detail of the discharge-valve and contiguous parts.
As the invention relates only to that part of the pump inserted in the well, the accompanying drawings only illustrate that part of the apparatus.
The ordinary deep well is provided with a tubular casing, and the apparatus here shown is designed to be fitted or inserted therein. This part of the pump comprises an upper tubular cast head a, a lower head b, and a tubular coupling-barrel c,providing an oil-chamber, in which the plunger works. The heads are of a diameter to snugly iit the well casing or lining and are each provided with threaded nipples e e', upon which the barrel c screws. Each head is further provided with passages d, extending longitudinally through the same outside of their axial chambers, which provides means for the circulation of oil to prevent sand settling at the lower end of the head b and, in addition, vents for the escape of gas. The head b is,in addition,provided with a plu rality of radial passes leading through the wall thereof for the passage of the oil as it is sucked in during the upstroke of the plunger, as will be hereinafter described. The axial passage or bore through the head b, which opens into the chamber formed by barrel c, is controlled by a gravity-valve, which inthe present instance is confined by a suitable cage. y The valve shown is a metallic ball f, which finds a seat on the edge of aring washer g, located in an annular recess in the inner periphery of the nipple e'. This washer is retained in place by the valve-cage c2, which is threaded into said nipple and which finds a bearing upon a peripheral Range thereon. The valve is drawn 0E its seatby the suction created by the plunger-head during the upstroke thereof, which is reciprocated in the usual manner.
The upper head a is provided with a sleeve h, forming a lining therefor, which guides the tubular plunger-rod 't'. This sleeve is made readily removable, so that it may be'replaced when worn, and to effect this end it is retained in place by lock-nuts h', threaded on each end thereof and screwed tightly against the adjacent ends of the head. The plungerhead is valved to provide for the passage of the fluid upward through the tubular rod. The valve is designed to be removed from its seat during the downward stroke of the plunger and to resume its seat as soon as the plunger commences its return stroke. As before stated, the plunger-head works entirely within the barrel c. In the structure of the head herein shown, which is the best embodiment of this part of our invention of which we are now aware, the valve mis carried by an axial stem n, depending axially from a yoke o, secured to the lower end of the plunger-rod z'. As shown, the stem n is secured at one end in the valve m and extends at its opposite end through an enlarged central portion of a bar o', connecting the ends of the yoke. The yoke is connected, by means of an internally-threaded integral ring 02, to the rod t', said ring being screwed upon the lower end of said rod. Screwed upon the exterior of this ring o2 and depending therefrom is a cylinder r, in which a tubular member or sleeve s is guided, said sleeve being provided with a flanged lower edge providing a seat for the valve fm. The cylinder ralso confines and guides a spiral spring t2, which finds a bearing at one end upon the ring o2 and presses at its opposite end upon the sleeve s to exert a tension to hold the valve-seat upon the valve m. The iiange t', in addition to providing a seat for the valve, also provides an enlarged pressure-surface to be acted upon by the iiuid in barrel c to unseat the valve, as will be described hereinafter. The outer edge of the liange t does not lit snugly against the inner periphery of the barrel c, but a suiiicient clearance is provided to prevent the formation of a vacuum during the upstroke of the plunger.
In assembling the parts of the pump the inlet-valve and coacting parts are fitted to the lower head and the latter screwed into the barrel c. The lining-sleeve h of the upper head a is then inserted in the latter and locked in place by nuts 72.. The plunger-rod is then passed therethrough, the plunger-head being passed into the barrel c. The apparatus is then inserted in the well, the heads ab, as before stated, snugly fitting the same. Then the proper length or section of tubing is coupled to the rodi to properly connect it with its reciprocating medium.
In operation during the upstroke of the plunger the lower valvefwill be drawn from its seat, and the oil flowing in through head b will enter chamber c. During this stroke the valve m is held tightly against its seat by the spring t2 pressing against the sleeve s. Ou the downstroke of the plunger the valve m will be forced from its seat, as the resistance oered by the fluid in the chamber c to the downward movement of the plunger-head pressing against the Iiange t' of the sleeve will be suiiicient to overcome the force exerted by the spring t2, and the sleeve will consequen tly be pressed upwardly within the cylinder r, thus removing the valve-seat froml the valve.
It is important that the lower head of the pump be maintained inl the bottom of the well, and for this purpose the upper and lower heads are made of heavy castings. The compression of the iiuid beneath the plungerhead in the downward movement of the plunger also serves to press the pump to the bottom of the well.
All the parts of the apparatus which are subjected to wear are made of steel tubing, and as these parts may be readily removed and replaced when worn the entire pump is practically indestructible.
Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is
l. A pump substantially as described, including a tubular plunger-rod and a plungerhead comprising a yoke secured to the end of said rod, a stem depending therefrom, a valve carried by said stem, a cylinder also depending from said rod, and a movable valve-seat guided therein, substantially as described.
