Definitions

  • This invention relates to an arrangement of the kind (herein called -the kind defined) including an electric motor-pump assembly which is submersible in a waste water sump orother liquid-container and which is guided during lowering into position by guide elements co-operating with guide means and of which the delivery connection piece in its lowered position is connectable with the inlet of a delivery conduit.
  • the known pump assembly arrange-- ments of the kind defined there is, for example, secured to the bottom of the liquid-container a pipe bend provided with a foot.
  • this pipe bend provided with a foot serves for the connection of the delivery conduit, and on the other hand it serves as an abutment for the delivery outlet piece of the pump to be connected therewith, which pump in a lowered position, for example under the influence of its own weight,
  • connection pedestal which can be secured in position in the liquid-container and which is provided with a passage opening for the liquid being pumped, which pedestal serves as a foot for the guide means and also serves as an abutment for the delivery outlet piece of the pump, and to which connection pedestal moreover the inlet part of the delivery conduit can be connected securely at the side lying opposite to the delivery outlet piece of the pump.
  • the pipe bend may, for example, be a commercially conventional article.
  • connection plate to which on one side the pipe bend of the delivery conduit may be attached by flanges, while the opposite side can be connected to the delivery outlet piece of the pump.
  • this connection plate may carry at its upper edge boss-like means for receiving the lower ends of the tubes which may be pushed without noticeable free play over those bosses and then, for example, may be secured by a fastening pin.
  • the invention further provides in a submersible pump assembly arrangement of the kind defined that, especially in connection with the above-described connection plate, the delivery outlet piece of the pump is provided with a flange-like intermediate connection piece which carries the guiding elements by which the pump assembly is guided upon the guide means.
  • This intermediate connection piece of the pump which serves as a counter flange for the connection plate can at the same time be extended in order to achieve a secure sealing between the pump and the delivery conduit, in that it is constructed as a holder for a seal.
  • annular seal which has a U-shaped profile in cross-section and which grips the inner margin of the intermediate connection piece attached to the pump, whereby one limb of the ring of U-shaped cross-section formed as a sealing ring lies between the intermediate connection piece and the pump delivery outlet piece, and the oppositely lying annular part of the seal effects the sealing between the intermediate connection piece and the connection plate.
  • the invention permits manifold possibilities of construction.
  • FIG. 1 shows in vertical section the lower end of a guide tube with the adjoining connection parts of a pump and delivery conduit
  • FIG. 2 shows a view towards the connection side thereof with the pipe bend removed.
  • a foot 11 which is secured by means of the screws with nuts 12 indicated in FIG. 2.
  • This foot 11 carries an upright standing connection plate 13 which is braced against the foot 11 by means of strengthening webs 14, 15 and 16.
  • the connection plate 13 is provided with a passage opening 131 which is surrounded on both sides by protuberant annular surfaces 132 and 133.
  • a connecting flange 181 is secured against the annular surface 132, the flange 181 being on a pipe bend 18 of which the second flange 182 can be connected with a delivery conduit (not shown) loading upwardly.
  • a delivery conduit (not shown) loading upwardly.
  • the delivery outlet piece 19 of the pump assembly presses with its seal 21 held by an intermediate connection piece 20.
  • the intermediate connection piece is secured to the flange 191 of the delivery outlet piece 19 of the pump assembly by means of screws (not shown) and has at its inner periphery an opening which accommodates the seal 21.
  • the seal 21 has a U-shaped crosssection and grips around the inner periphery of the intermediate connection piece 20, a washer-shaped part 211 of this seal 21 being clamped between the delivery outlet flange 191 and the intermediate connection piece 20.
  • the further washer-shaped part 212 of the seal 21 lies against the free side of the intermediate connection 20 and upon pressing of the pumpagainst the connection plate 13 lies against the annular surface 133 thereof so that there also there is achieved a good sealing.
  • connection plate 13 at its upper edge carries a locating boss 22 for the lower end of a guide tube 23 which serves for the guiding of the pump assembly during lowering and raising.
  • the end of the guide tube can be secured upon the locating boss 22 by a fastening pin (not shown).
  • a guide collar 24 Around this guide tube 23 as a guide element there engages a guide collar 24 which rests upon the intermediate connection piece 20 and has an aligning slit 241 which widens conically downwards.
  • a submersible electrical motor-pump assembly having a drive motor, a pump with a delivery outlet connected therewith, and a conventional tubular guide element, the assembly being lowerable into a body of fluid with the outlet of the pump being guided by the tubular guide element into a complementary position for fluid flow connection'with an inlet opening ofa discharge pipe; the assembly comprising in addition: a connection pedestal disposed between said pump delivery outlet and said inlet opening of said discharge pipe, a flange-like connection plate, on the pedestal, connected to the delivery outlet and to the inlet opening, thus providing a passage opening for the fluid to be pumped; a boss-like locating means, attached to the upper edge of the connection plate, for aligning and setting thereupon the lower end of said tubular guide element; means securing said guide element to said locating means; a flange-like intermediate connection element, on the delivery outlet, comprising a guide sleeve adapted to be in sliding engagement with said guide element; said connection pedestal serving as a foot for the guide element and as an
