FIGS. 1A through 1C show aPRIOR ART pump 10 having apower end 11 and afluid end 12. Thepower end 11 contains a crank shaft converting rotational forces (e.g., from a diesel engine or another power source) into reciprocating forces, and thefluid end 12 contains pistons and valves to pressurize various fluids to relatively high pressures. “Stay rods” or “tie rods” 15 lock thefluid end 12 to thepower end 11. Due to such factors as vibration, stresses, and stress cycling, theprior art pump 10 may experience problems with cracking and separation within each of the bodies, frames, and at or near thestay rods 15, leaving thefluid end 12 and thepower end 11 inadequately fixed relative to each other. In addition, installing thestay rods 15 typically requires special tools and training, and may be labor intensive and tedious. -
FIGS. 2 through 12 show apump 100 according to an embodiment of the current invention. As with theprior art pump 10 thepump 100 broadly includes apower end 110 and afluid end 120. But thepump 100 includesplates 130 to couple thefluid end 120 to thepower end 110. More particularly, thepump 100 has a plurality ofplates 130 extending from thepower end 110. Theplates 130 each have aproximal end 130 a and adistal end 130 b. Theproximal ends 130 a may be formed unitary with thepower end 110, or may be fixedly coupled to thepower end 110 in any appropriate manner (such as through welding or bolting). Thedistal ends 130 b have elongateengaging structure 132, with each of theengaging structure 132 extending generally parallel to each other of theengaging structure 132. It may be desirable for theengaging structure 132 to extend for a distance D (FIG. 3 ) that is at least fifty percent as long as a height H (FIG. 5 ) of thefluid end 120, more desirable for theengaging structure 132 to extend for distance D that is at least eighty percent as long as height H, and even further desirable for theengaging structure 132 to extend for distance D that is at least ninety percent as long as height H. Nevertheless, in some embodiments, it may be satisfactory for theengaging structure 132 to extend for distance D that is less than fifty percent as long as height H. - As best shown in
FIGS. 4 and 6 , thefluid end 120 has complementaryengaging structure 122 for interlocking with theengaging structure 132. The complementaryengaging structure 122 shown inFIGS. 4 and 6 is formed (i.e., cast, machined, et cetera) instructural block 121 of thefluid end 120. In other embodiments, the complementaryengaging structure 122 may be fixedly coupled to thestructural block 121. For example, the complementaryengaging structure 122 may include a plurality of tracks that are welded, bolted, or otherwise affixed to thestructural block 121. Moreover, while theengaging structure 132 in theembodiment 100 is male engaging structure and the complementaryengaging structure 122 in theembodiment 100 is female engaging structure, theengaging structure 132 may be female engaging structure and the complementaryengaging structure 122 may be male engaging structure in other embodiments. Still further, the complementary engaging structure may be constructed of multiple components which collectively allow engagement. For example, both theengaging structure 132 and the complementaryengaging structure 122 may include male engaging structure, and the complementaryengaging structure 122 may further include clamps, bolts, or other fasteners which bind the two together. And in some embodiments, the proximal ends 130 a of theplates 130 may be fixedly coupled to thefluid end 120 and the distal ends 130 b may interact with complementary engaging structure formed in or affixed to thepower end 110. - The engaging
structure 132 and the complementaryengaging structure 122 has a generally circular cross section, as shown inFIG. 6 . Yet other shapes may alternately be used, such as rectangular, hexagonal, octagonal, oval, and semi-circular shapes. And while each of theplates 130 is shown having an equivalent length such that the engagingstructure 132 is aligned in plane 133 (FIG. 6 ), the lengths of theplates 130 may vary so long as the complementaryengaging structure 122 aligns with the respectiveengaging structure 132. - Locking
plates 140 couple thepower end 110 to thefluid end 120 and prevent disengagement of the engagingstructure 132 and the complementaryengaging structure 122. As shown, for example, inFIGS. 2, 3, and 7 , fasteners 141 (e.g., bolts, screws, welding, et cetera) may affix the lockingplates 140 to thepower end 110 and to thefluid end 120. It may be particularly desirable for thefasteners 141 to be axially offset angularly from a direction of sliding engagement between the engagingstructure 132 and the complementaryengaging structure 122, though some embodiments may not include such a configuration. In theembodiment 100, thefasteners 141 are axially offset generally perpendicularly from a direction of sliding engagement, though other angles may alternately be used. And in some embodiments, the lockingplates 140 may be formed unitary with either thepower end 110 or thefluid end 120. - To assemble the
fluid end 120 to thepower end 110, theplates 130 are coupled to thepower end 110 or formed unitary with thepower end 110. Thefluid end 120 is positioned (e.g., using a hoist) such that the complementaryengaging structure 122 is aligned with the engagingstructure 132, and thefluid end 120 is then lowered with the complementaryengaging structure 122 slidingly engaging the engagingstructure 132. As thefluid end 120 moves to the desired location relative to thepower end 110, thefluid end 120 may interact withsuction manifold 150 and pretension the suction gaskets of themanifold 150. The lockingplates 140 are then installed using thefasteners 141. Thefluid end 120 may include at least onestop 128 to prevent further sliding of thefluid end 120 relative to theplates 130, and to help indicate when thefluid end 120 is in the correct location for thefasteners 141 to be installed; this may be a redundant (though in some cases desirable) feature. Thestop 128 is shown inFIG. 8 as a layer of thestructural block 121 without the complementaryengaging structure 122, but thestop 128 may take other forms as well. Thefluid end 120 may subsequently be separated from the power end 110 (e.g., for maintenance) using a reverse sequence: thefasteners 141 and the lockingplates 140 are removed to allow sliding between the engagingstructure 132 and the complementaryengaging structure 122, thefluid end 120 is lifted (e.g., with a hoist) so that the complementaryengaging structure 122 slides relative to the engagingstructure 132 and thefluid end 120 separates from the slidingplates 130 and thesuction manifold 150. - The
power end 110 shown inembodiment 100 is hydraulically driven and foregoes the crankshaft in thetraditional power end 11. This may help reduce vibration and cracking, and the use of theplates 130 in conjunction with thehydraulic power end 110 may be synergistic and together offer even superior and unexpected results. Nevertheless, theplates 130 and the other disclosed structure may be used with traditional (rotating) power ends 11 and achieve results superior to theprior art system 10. And the hydraulic drivenpower end 110 may be used with the stay rods 15 (as shown, for example inFIG. 13 ) and achieve results superior to theprior art system 10. - In the
embodiment 100, thepower end 110 has double acting cylinders supporting opposing fluid ends 120, although those of skill in the art shall understand that such a pump configuration is not necessary, and that thepower end 110 may include only single acting cylinders supporting onefluid end 120. Nevertheless, inembodiment 100, the lockingplates 140 and slidingplates 130 are shown as separate plates (e.g.,FIG. 2 ) that extend in either direction between thepower end 110 and the respectivefluid end 120. -
FIG. 14 shows anotherembodiment 200 which is substantially similar toembodiment 100, except as is shown and described or as would be inherent. Here, theend plates 240 and the slidingplates 230 are single plates extending from onefluid end 220 to the other. Theend plates 240 are otherwise substantially similar toend plates 140. Similarly, the slidingplates 230 are substantially similar to slidingplates 130, and may include engaging structure for engaging with the respective fluid ends 220 as is described herein. - Many different arrangements of the various components depicted, as well as components not shown, are possible without departing from the spirit and scope of the present disclosure. Embodiments of the present disclosure have been described with the intent to be illustrative rather than restrictive. Alternative embodiments will become apparent to those skilled in the art that do not depart from its scope. A skilled artisan may develop alternative means of implementing the aforementioned improvements without departing from the scope of the present disclosure. It will be understood that certain features and subcombinations are of utility and may be employed without reference to other features and subcombinations and are contemplated within the scope of the claims. The specific configurations and contours set forth in the accompanying drawings are illustrative and not limiting.
