Definitions

  • PATENTEDmszs m2 PRIOR ART GUIDING DEVICE FOR PUMPS LOWERABLE IN SHAFTS
  • the invention relates to a guiding device for pumps submersible in shafts and, via a guide block or the like, steered by means of downward directed structural members or the like.
  • the object of the present invention is to eliminate or at least greatly reduce these disamenities at such pump stations with two or more pumps.
  • the guiding device is torsioned, inclined, bent or otherwise shaped in such a way that the pump, when raised and lowered, is caused to move also sideways, the paths of motion of the various pumps diverging in the lowering operation and converging in the raising operation.
  • FIG. 1 shows a shaft opening for a single-pump station, viewed from above
  • FIG. 2 the shaft opening of a conventional doublepump station, viewed from above
  • FIG. 3 the shaft opening of a double-pump station according to the invention, viewed from above,
  • FIG. 4 a vertical section through a double-pump station according to the invention
  • FIG. 5 the shaft opening of FIG. 4, viewed from above
  • FIG. 6 an alternative embodiment, viewed from the side
  • FIG. 7 is a schematic of helical guide means.
  • FIG. 1 shows the shaft opening 1 of a single-pump station.
  • the pump 2 can be raised and lowered and is guided by means of a guide block, not illustrated, running on two tubular guides 6 and 7.
  • the guides 6 and 7 are secured at the top by means of an upper attachment 4.
  • FIG. 2 The shaft opening of a conventional double-pump station is shown in FIG. 2, in which two pumps 2 and 3, in the same way as in the embodiment in FIG. 1, are vertically steered by straight tubular guides 6 and 7 and, respectively, 8 and 9, secured to the upper attachments 4 and 5. It is clearly seen that the shaft opening 1 in FIG. 2 is roughly twice as large as in FIG. 1. Either the cover of the shaft, therefore must be considerably more robust owing to its size or an extra loadbearing structure 20 must be arranged.
  • FIG. 3 shows the shaft opening of a doublepump station, but in this case, through application of the invention, the size of the opening is practically the same as for the single-pump station in FIG. 1.
  • the upper attachments 4 and 5 of the essentially straight tubular guides are placed in the corners of the opening and set at an angle in relation to the lower guide attachments, so that the pumps 2, 3, when raised or lowered, slide in a helical path round a vertical axis between a lower, swung-out position 10 and an upper position 11 swung-in towards the center, so that the smaller shaft opening 1 will be sufficiently large.
  • one tube 7, 9 may be straight and the other 6, 8 run in a helix round the former.
  • FIG. 4 A vertical section through a double-pump station according to the invention is shown in FIG. 4, its horizontal section in FIG. 5.
  • the shaft 13 of the pump station has a cover 18.
  • the upper attachments 4 and 5 Immediately under the cover 18 in two corners of the shaft opening 1 are the upper attachments 4 and 5 to which are secured the slightly flexible tubular guides 6, 7, 8, 9.
  • the attachments 4 and 5 are again set at an angle with respect to the associated fittings 14 and 15 for, respectively, the outlet flanges l6 and 17 of pumps 2 and 3.
  • FIGS. 4 and 5 One pump 3 is shown in FIGS. 4 and 5, partially by dotted lines in the lower, swung-out position 10, corresponding to its working position.
  • the outlet flange 17' 'of the pump 3 bears against the pipe line flange 19 of the fitting 15.
  • the pump 3 When the pump 3 is raised, it slides with the guide block 12 along the tubular guides 8 and 9, is turned towards the center of the shaft opening and finally assumes the upper position 11, shown by fully drawn lines, swung-in towards the center, where the outlet flange 17 of the pump forms a given angle with flange 19 of the fitting 15.
  • FIG. 6, finally, shows an alternative embodiment in which the guides 6, 8 are set at an incline, approaching one another towards the top.
  • Each guide may consist, for example, of two tubes or an I-beam, T-beam or the like, and here runs straight along its entire length.
  • the guide may be formed with a bend or in a gradual arc, in which case the two guides 6, 8 can run parallel to one another at their top end while running apart at the bottom end.
  • the guide blocks 12 and fittings of the pumps 2, 3 may be of optional form and are not covered by the invention, for which reason no details in these respects are shown in the figures. The same applies to the actual hoisting and lowering device, which may be of known type and is not shown in the drawing.
  • the invention permits a reduction of the shaft opening, and the elimination of the otherwise necessary extra load-bearing structure or reinforcement of the cover, compared with corresponding single-pump stations.
  • the invention is not limited to doublepump stations but is also applicable to pump stations with arbitrary number of raisable and lowerable pumps.
  • the form of the guide device according to the invention limited to the use of tubular guides, but any guide device whatsoever can be used which permits a lateral movement in conjunction with hoisting or lowering.
  • the lateral movement necessarily consist of a swinging motion as indicated in the embodiments in FIGS. 3-5, or in a lateral displacement as in FIG. 6, but may also take place by other means.
  • the lateral movement need not take place successively during the entire vertical movement but can, of course, take place along a limited portion of it, and also in one or more steps.
  • the guide device of only one pump may be constructed according to the invention and the other by conventional means.
  • FIG. 7 discloses guide means consisting of a straight tube 16 and a second tube 17 extending helically about the straight tube 16.
  • a guiding device for pumps lowerable in a shaft to an operative position comprising:
  • each respective pump for horizontally rotating each pump from its initial position at the entrance of the shaft to its operative position, the paths of the pumps along the guide means diverging during their lowering and converging during their raising relative to each other;
  • each pump for connection to its respective guide means.
  • a guiding device according to claim 1 where the guide means includes members that are slanted relative to the vertical axis of the shaft.
  • a guiding device according to claim 1 where the guide means includes two rod members that are twisted relative to each other about their common mid line.
  • a guiding device according to claim 1 where the guide means includes a pair of rods, one straight and the other extending helically about the axis of the straight rod.
