Definitions

  • This invention relates generally to the class of centrifugal pumps and pertains more particularly to pumps of this type, of heavy construction, such as are used in pumping sand loaded liquids and chemical solutions.
  • Centrifugal sand pumps of the large and heavy type with which the present invention deals embody a circular case portion which is fitted across its diameter to a follower plate and intake chamber.
  • the case is set or rested through feet on the bottom thereof upon a supporting base.
  • the cases have in some instances been fitted to or on a back plate and held in place by case bolts. Due to the heavy weight of the case, however, the preferred, and what is thought to be the best, mounting is through the case feet.
  • the pump case must at times be detached from the follower plate and intake chamber either for complete removal and replacement or for the inspection of the wear parts and the presently employed manner of mounting the case presents certain disadvantages and problems particularly with respect to the replacement of the case, as it is difficult to realign the parts of the case, follower plate and intake chamber.
  • different methods are employed to obtain the proper positioning of the case upon the base with respect to the other parts of the pump with which it must be joined or connected.
  • the handling of the case is effected by means of a suitable crane or by the employment of a lift truck and in order that the case will be accurately set, one practice is to machine the bottom of the case feet.
  • the bottom of the case feet are machined and also the supporting base and the individual shims.
  • the individual shims such as manganese steel, alloy steel or even white iron, the machining of these metals is slow and costly.
  • a particular object of the present invention in view of the foregoing, is to solve the problems and overcome the present difficulties associated with the proper placement and alignment of such a case'by providing the case with a foot construction or formation whereby the case is of exactly the correct height from the bottom of the feet to the center line thereof Without having to machine the feet or employ shims or similar devices to accomplish the proper alignment of the case when it is set up on the base with the follower plate and intake chamber.
  • Another object of the invention is to provide a case in on pumps in use in the field, thereby making itpossible 3,622,74h Patented Feb. 27, 1%2
  • Still another object of the invention is to provide an improved case placement and alignment means embodying shim bars associated with'the pump supporting base together with a new and novel case foot construction by means of which the pump case may be readily moved from operative position with respect to the other parts of the pump and replaced in such position without requiring the services of a crane or lift truck.
  • Still another object of the invention is to provide in association with a centrifugal pump structure of the character stated a new and novel case placement and alignment means employing in a cooperative relationship an improved form of supporting feet for the case with supporting shim bars upon which such supporting feet are adapted to slide, together with means forming a part of the base between the shim bars for facilitating the shifting of the case on the shim bars into and out of operative relationship with the other parts of the pump with which it is aligned by the novel foot construction by which it is supported.
  • the invention broadly contemplates the provision of shim bar extensions for the portions of the base upon which the feet of the case rest.
  • the feet of the case are formed or cast a prescribed amount short of the usual height.
  • the feet are then filled out on the underside with a cast metal sole the thickness of which is accurately controlled so that each case having the feet so extended will be exactly the same height from the bottom of the feet to the center line of the case.
  • the cast metal sole for each foot rests upon the top of the extended shim bar and in addition to supporting the case in proper alignment with the follower plate, such soles facilitate the movement of the case with respect to the follower plate by acting as runners for sliding movement along the surfaces of the shim bars.
  • the case is guided on the shim bars and held against lateral movement by lateral guards forming portions of the inner sides of the supporting feet.
  • the base between the shim bars is formed with a longitudinal line of short transversely extending spaced cleats by means of which and the use of a pry bar in engagement therewith, movement of the case along the shim bars is readily effected so that separation of the case from the follower plate is readily accomplished without the necessity of using a crane or lift truck.
  • Flihl is a view in perspective of a centrifugal sand pump of the type with which the present invention is concerned, showing in association therewith features of the present invention
  • FIG. 2 is a view in perspective and on a smaller scale of the pump structure shown in FIG. 1 as viewed from the opposite side or that side where the power is delivered to the pump and showing the jack screws employed for breaking the case away from the follower plate;
  • FIG. 3 is a view in top plan of the: pump showing the extended shim bars and the pry bar cleats;
  • FIG. 4 is a view in side elevation ofthe pump structure and illustrates the action of the jack screws in breaking the case from the follower plate;
  • FIG. 5 is a sectional view on an enlarged scale taken in a vertical plane approximately on the line 55 of FIG. 1 and illustrating the metal sole for the foot which rests upon the shim bar;
  • FIG. 6 is a sectional view on an enlarged scale taken in a vertical plane transversely of the foot approximately upon the line 6-6 of FIG. 1;
  • FIG. 7 is a sectional view corresponding to FIG. 5 and illustrating a modification of the metal sole plate for a foot of the case.
  • the numeral 14 generally designates a centrifugal sand pump of a heavy construction and in connection with which the present invention is used, While the numeral 12 generally designates the base upon which the pump is mounted.
  • the pump structure comprises broadly th pump case which is generally designated 14, the intake chamber to which the case is secured and which is generally designated 16 and which has located or positioned between it and the case 14 the follower plate 18.
  • the intake chamber comprises the conventional housing 20 to the rear side of which is secured in the usual or a known manner the bearing housing 22 through which extends the shaft, not shown, which is connected to a drive motor for operating the pump.
  • the numeral 2 2 designates the intake connections at opposite sides of the intake chamber with which are connected the pipelines through which material is delivered to the pump for discharge by Way of the case 14 through the case discharge outlet 26.
  • the case discharge 26 is here illustrated as extending vertically and has coupled therewith the adjustable discharge sleeve which is generally designated 28 and by means of which connection is made with a delivery pipe, not shown.
  • the case 14 is fitted to the intake chamber housing 20 by means of the follower plate 18 and it is drawn tightly into operative position by means of the stud bolt 30 which are fixed to lugs carried by and positioned around the periphery of the intake chamber housing as most clearly shown in FIG. 2.
  • a pair of upwardly extending lugs 31 to which the uppermost stud bolts are fixed and which are here shown as being relatively short but which may be extended, or made longer, if necessary.
  • lugs 32 extend outwardly as illustrated and each of which carries a stud bolt 30.
  • the pump case 14 has cast integral therewith and around the periphery or outer circular portion thereof the apertured lugs 33 and 34. These lugs are positioned so that when the case is moved into position. against the intake chamber housing the threaded ends of the stud bolts will extend therethrough to receive the nuts 35.
  • the numeral 36 designates an additional lug on the top of the pump case 14 for connection with the case of a suitable crane or hoisting mechanism when it becomes fiecessaryto lift the case entirely elf of the supporting ase.
  • the pump case stands upon feet which rest upon the pump supporting base 12.
  • This base in presently known pump structures or conventional structures, extends only sufiiciently far beyond the intake chamber housing to provide the proper surface upon which the case feet may rest.
  • These case feet which are cast integral with the pump case are here designated 37 and 38 and as has been previously set forth, the presentpractice for aligning the case with the intake chamber and follower-plate consists either in machining the bottom faces of the supporting feet as may be necessary, or by placing shims between the case feet and the underlying portion of the base upon which the feet rest.
  • the intake chamber casing in also is cast with sup porting feet 39, shown in FIG. 2, and these feet rest upon flat tops of upstanding portions of the base 12 lying beneath the case 2%, one only of such portions being shown in FIG. 2 and designated 40, such upstanding portions being cast with the base 12.
  • the frame base 12 is extended from the portions 40 forwardly beyond the pump case 14, as is clearly illustrated in FIGS. 1 and 2.
  • This extended portion of the base comprises the upstanding side rails 41 and 42. which constitute continuations of the portions 46.
  • the bottom or floor of the base between these rails 41 and 42 is designated 43 and this floor portion of the base between the rails carries in a longitudinal array upon its top surface the series of short transversely directed lugs 44 which are designed to be used in association with a suitable pry bar, as hereinafter described.
  • the rails 41 and 42 forming the forward extensions of the pump base have mounted longitudinally thereon the shim bars 45 and 46.
  • the top surfaces 47 and 48 re spectively are smooth to facilitate the sliding of the specially formed feet 37 and 38 thereon in the operation of shifting the pump case with respect to the intake chamber and follower plate.
  • the following procedure is carried out in connection with the cast feet.
  • the feet In the casting of the casing and the feet integral therewith the feet are cast approximately /2 inch short of the usual height.
  • the holes conventionally formed in the feet are as shown in FIGS. 5 and 6 enlarged at their upper ends.
  • the foot 38 which as shown in FIG. 1, is cast on the side of the pump case beneath the discharge 26, has the two bores 49 thereof upwardly flared as indicated at 50.
  • the under face 51 of the foot is formed with a shallow recess 52. This recess extends through the major portion or" the length of the foot and across the major portion ofthe width, as shown in FIG. 6.
  • each foot there is provided at the inner side of each foot the downwardly extending shoulder 53 and the space between these shoulders is approximately equal to the space between the inner sides of the top portions of the shim bars 46 and 4.7 so that when the case is located in position on the shim bars, these shoulders 53 will engage or be in close proximity to the inner surfaces or inner portions of the shim bars and will function to prevent any lateral movement or twisting or turning of the case as it is being moved into operative position.
  • the recesses 52 formed in the undersides of the case feet are filled with a suitable low melting metal, metal alloy, plastic or cement and this filling forms a sole portion on the bottom of the foot which is of a thickness to project-beyond the lower face 51 of the foot as is clearly shown in FIGS. 5 and 6, and these sole portions which are designated 54 rest and are adapted to slide upon the smooth top surfaces 47 and 48 of the shim bars.
  • bah-bit metal is one material which has been found to be entirely satisfactory for use.
  • FIG. 7 illustrates the slightly modified form or construction for the bearing sole for the case feet.
  • a low friction metal plate 55 is provided which forms the sole plate and which sole plate rests and slides upon the smoothed top surfaces 47 and 48 of the shim bars 45 and 46.
  • This plate has secured to the top surface thereof in a suitable manner as by welding, the wire mesh 56 and a low melting point metal or other suitable bonding material is introduced through the bore 49 of the foot body while the sole plate and wire mesh are in the position illustrated in FIG. 7 to establish a secure bond between the plate and the bottom of the case foot.
  • the bonding material between the bottom of the case foot and the sole plate 55 is designated 57.
  • the low melting point metal may be lead, babbit or tin or, if desired, the bonding material may comprise a plastic, resin, or any suitable type of cement.
  • the wire mesh which is preliminarily bonded by Welding or other means to the top of the soleplate, a good bond is obtained between the sole plate and the material 57 which is cast onto the top of the plate through the bore 49'.
  • the sole plate 55 may be cold rolled steel, brass or aluminum.
  • the case When the case is set in position the flat bottom faces of the soles, or sole plates 54 or 55, of the feet will rest upon the smooth top surfaces of the shim bars and due to the manner of casting or shaping the soles so that the cases will be of the required height from the bottom of the feet to the center line, the case can be accurately aligned with the follower plate and slid into position.
  • the rails 41 and 42 together with the shim bars 47 and 48 mounted thereon will be of standard height and this, together with the standardization of the case supporting feet, will facilitate the accurate alignment of the case, as stated.
  • the sliding of the case on the shim bars can be easily effected by using a pry bar such as is illustrated in FIG. 4 and designated 58, by engaging the lower end of the bar between two of the base cleats 44 and prizing the case forwardly.
  • a pry bar such as is illustrated in FIG. 4 and designated 58
  • the case stud bolts will pass through the apertured lugs 33 and 34 and the securing nuts can then be placed on the bolts and the case drawn tightly in position.
  • the adjustable discharge sleeve 28 will then be properly located to have the lower section thereof moved down into coupling relation with the top end of the case outlet 26.
  • the adjustable discharge sleeve comprises, as is set forth in the copending application hereinbefore referred to, the upper and lower portions 28a and 28b.
  • the lower portion 28b is slidably engaged in the lower end of the larger upper portion 28a and when it is moved downwardly, after the placement of the pump case in position, it may be joined to the flanged top end of the pump case discharge 26 by the coupling bolts 59.
  • the upper end of the upper section 28:: of the discharge sleeve is'flanged' as indicated at 60 for connection with a standpipe.
  • jack screws are suitablyheaded on the ends thereof remote from the case 14 to facilitate the connection of a wrench therewith while the opposite ends of the jack screws engage against the adjacent wall of the case 14 so that when the jack screws are rotated in the proper direction they will impose pressure or thrust against the case and break the same away from the follower plate 48 in the manner illustrated in FIG. 4.
  • the case has thus been loosened, it can be readily slid on the shim bars away from the follower plate without the necessity of using a hoist or crane and after the necessary inspection has been madeor the case has been replaced, if required, it can be readily slid back into connection with the follower plate in perfect alignment therewith due to the manner in which the case feet have been fitted with the proper thickness of elevating sole.
  • the shim bars upon which the feet slide may be made of any suitable length. In some installations there bars may be extended to a length which would permit the case to be moved or slid far enough away from the follower plate so that a worn runner and follower plate might be replaced if necessary. Such an extension of the shim bar would, however, only be necessary in situations where there may not be an overhead crane or a lift truck could not get to the pump to engage the apertured lift lug 36. Even in this case it is, of course, obvious that the case must be slid out sufficiently far to clear the stud bolts and the pump runner before it could be lifted from the base.
  • the present invention provides a novel base structure which facilitates the movement of the case back and forth with respect to the follower plate while maintaining it in proper alignment with the follower plate at all times and the invention also pro-'- vides novel means by which the case can be easily broken away from the follower plate so as to permit it to be shifted away therefrom with a minimum of effort.
  • the case In addition to providing a means for the smooth movement of the case on'the shim bars, by the sliding of the soles for the cast feet on the top surfaces of the bars, the case will be held effectively against any lateral movement or twisting movement on the shim bars through the sliding engagement of the shoulder portions 53 at the inner sides of the feet with the adjacent inner sides of the shim bars.
  • the case may be cast with the feet 37 and 38 in different locations so that the case discharge can be set in as many as six different discharge positions.
  • the volute of the case increases in size from the part where the apertured lug 36 is located to the discharge. Since the feet 37 and 38 must always be on the bottom of the case, they will vary in height as the case is turned. Because of this volute slope, one foot is higher than the other and thus shim bars of difierent heights are required.
  • an intake housing a case detachably secured thereto, a base for supporting the housing and case, the case having supporting feet andthe base including spaced portions supporting the feet and extending in a direction paralleling the axis of the pump, means for aligning the center of the case with the center of the said housing comprising sole forming bodies covering the major portions of the undersides of the feet and adapted to bear upon said spaced portions of the base and said sole forming bodies being so joined to the feet that the bottoms of the bodies are at the correct vertical distance from the centerline of the case whereby the case will be exactly aligned with the said housing when the sole forming bodies are resting on said portions of the base and the case may be shifted on the base for separation from the housing and the alignment of the centers of the case and housing maintained to facilitate accurate reverse shifting and rejoining of the case and housing.
  • an intake housing a case removably joined thereto, a base for supporting the housing and case, said base having a substantial length and extending from beneath the case to a substantial distance beyond the side of the case remote from the housing, spaced parallel bars extending lengthwise of the base in a direction paralleling the axis of the pump, and feetcarried by the case and supported upon said bars and adapted for sliding movement on and longitudinally of the bars in the operation of separating the case from the housing whereby axial alignment of the housing and case is maintained to facilitate rejoining the same.
