RECIPROCATING PUMP WITH INDIVIDUAL JOINTS BETWEEN PLUNGERS.
Application led February 13, 1924. i Serial No. 692,514.
Our present invention relates to reciproeating pumps especially suitable for use in deep wells, such as oil wells, and more particularly to pumps comprising separate short plungers or plunger sections, each provided with a valve and all cooperating with a common cylinder or barrel, or with replaceable or sectional liners retained in such a. cylinder or barrel; and itis an especial object of this invention to provide apump whose reciprocating plunger sections are connected by novel individual joints permitting both a pivotal and a. sliding movement therebetween in a manner favorable to easy and ctfcctive operation and to the avoidance of undue strain or wear.`
It is already recognized that an ordinary one-piece plunger, as heretoforey commonly used, is liable to become detective in operation by reason of failure to obtain or to maintain an all-around tit, or because of adverse conditionsy of temperature and pressure, during use, tending to produce distortions and to c-ause eccentric wear. In view of the conditions referred to,sectional liners have become popular and the Zublin pump has been introduced; and our present improvement is especially suitable for use in connection with multistage pumps of the Zublin type, or in connection with other reciprocating, heavy-duty pumps, whether using sectional or unitary liners.
. It is an object of this invention to increase the efficiency and prolong the lite of pumps comprising'two or more short plungers or plunger sections' by joining the mentioned short plungers or plunger sections in a. manner favorable to anl independent automatic centering of each section within a barrel or liner section, thereby minimizing side throw and eccentric wear ;v and our preterred means :for this purpose may comprise transverse pins or heads or other' connecting elements extending through slots or other openings suliciently4 large to permit of either a relative` pivotal movement or a lateral oifsetting movement, or any suitable combination of pivotal and offsetting movements, as may be required to enable the respective sections to adjust themselves independently, during their operation, into positions coaxial with the cylindrical element within which each may, at any given time, be moving.
Other objects of our invention will appear from the following description of an illus- ,or other liquid pumped;
trative embodiment thereof, taken in connection with the appended claims and the accompanying drawings, in which Fig., l is an elevational view of a` pump embodying our invention, with parts se@ tioned or broken away.
Fig. 2 is an enlarged detail sectional view showing one advantageous mode or means ot connecting a pair of short plungers or plunger sections. Y
Figs. 3 and 4 illustrate an alternative form in which threaded hinge elements, by which a pair of plungers'or plunger sections are connected, serve also as means for the retention of valve seats. Fig. 4 is taken in a plane at right angles to that represented in Fig. 3, and on a slightly larger scale.
Referring to the details or that specilic embodiment of our invention shown in Fig. 2, 1 may be a pump barrel, connected in the manner suggested in Fig. 1, or in any preferred manner, to a ,string otl pipe, and 2 may be a sectional or other linertherein, the respective shortplungers or plunger sections 3 `being provided with valves of any suitable character, not shown. Our invention' involves the use of novel coupling or connect- -ing means, such asthe loosely intertitting and complemental hinge elements el, 5, each of which may be provided with an exteriorly threaded head 6, adapted to engagea corresponding interior thread 7, in a plunger section, any suitable channels 8 being rprovided to permit of a tree relative movement oit' oil and the projecting portions ot' the respective hinge members l and 5 may be provided with transverse circular or non-circular apertures 9 and 10 adapted loosely to receive a transverse connecting member such as the Vpin 1l, shown as retained by means of cotters l2, extending through the opposite ends thereof. In order to permit of not only a pivotal movement between the hinge' elements l and 5, but also of a slidying movement therebetween, it is 4important that, as diagrammatically shown inV the drawing, ample clearance should be lett not only between the interfitting projections engaged by the pin ll, but also between the latter element and the walls surrounding the same.
Referring to the specific vembodiment of our invention shown in Figs. 3 and 4, an outer barrel being shown atl', and liner sections being shown at 2, the plungers or noy plunger sections V3 are shown as connected by hinge elements 4C', 5v of a slightly more complex structure adapting the same to serve not only as connecting means, but as means for the retention of valve seats 13, 13.
As before, the heads 6 may be exteriorly th readed to engage interior threads 7 within the respective plunger sections, and a pair of such threaded heads may be utilized, as is well illustrated in Fig. 1, in the retention of a valve sea-t, such as the reversible and replaceable valve seat 14, adapted to receive a ball 15; and one ot' the hinge sections 6 may then serve as a cage for the retention of such a ball.
In the forni of our invention shown in Figs. 3 and 4. we may employ a transverse pin 11 rigidly connected with one of the mentioned hinge elements, as by forming the said pin integral with a threaded body 16, shown as adjustable within a lower hinge element 5 and as retained against rotation therein by means of a rivet 17. When we employ such a construction as is here rcferred to, it will be obvious that the pin 11 may have. either a sliding or a pivotal engagement, or both a sliding and a pivotal engagement, upon shoulders 18 defining the passage 9 within which said pin is freely movable.
Although we have herein described two advantageous embodiments of our invention, it will be understood that important advantages of our invention might be obtained by any alternative type of loose pivotal connection between a pair or series of short plungers or plunger sections adapted for reciprocation within a barrel or liner or liner sections; and it will also be obvious that various features of our invention might be independently employed.
We claim as our invention:
1. A reciprocating pump comprising: a plurality of plungers disposed endwise to each other; and 4means for loosely connecting said plungers together, said means functioning additionally as a valve cage.
2. A reciprocating pump comprising: a plurality of comparatively short plungers disposed endwise to each other and close together; and means connecting said plungers and permitting movements of each plunger relative to the other plungers, said means functioning additionally as a valve cage.
3. A reciprocating pump comprising: a.
plurality of comparatively short hollow plungers disposed endwise to each other; a valve for cach plunger; and means loosely connecting said plungers together, said means functioning additionally as a valve cage.
4. A reciprocating pump comprising: a plurality of hollow plungers disposed endwise to each other and close together; a valve for each of said plungers; and means loosely connecting said plungers, said means functioning additionally as a. valve cage.
5. In a reciprocating pump, the combination of: a plurality of plungers hingedly connected by means permitting a lateral or offsetting movement between said plungers; and a valve seat, said valve seat being retained in place by said means. y
6. A reciprocating pump comprising: a plurality of plungers disposed endwiso to each other; means for loosely connecting said plungers together,said means functioning additionally as a valve cage; and a valve seat, said valve seat being retained in place by said means.
7. A reciprocating pump comprising: a plurality of comparatively short plungers disposed endvvise to each other and close together; means connecting said plungers and permitting movements of each plunger relative to the other plungers, said means functioning additionally as a valve cage; and a valve seat, said valve seat being retained in place by said means.
8. reciprocating pump comprising: a plurality of comparatively short hollow plungers disposed endwise to each other; a valve for each plunger; means loosely connecting said plungers together, said means functioning additionally as a valve cage; and a valve seat, said valve seat being retained in place by said means.
