Definitions

  • the invention relates to a submersible pump of the type specified in the preamble of the main claim.
  • the submersible pump When the submersible pump is on its side, it can no longer pump water out as soon as air is drawn into the inlet openings. The same occurs when the submersible pump has its outlet port on the top and it is placed in a wide container or wide pit for pumping out.
  • the weight of the line and the train it exerts, as well as the movements of the lines when pumping, then act in relation to the footprint with a relatively large lever arm, so that the submersible pump tends to tip over and this in turn sucks in air before the water is complete is pumped out.
  • a submersible pump for conveying viscous substances which has two outlet openings in its upper housing part, one of which is directed upwards and the other is directed to the side.
  • the openings can optionally be closed by a flap mounted in the upper part of the housing.
  • the pump has a vertically downward mandrel on the lower part of the housing, with which it is inserted into the viscous substances to be pumped for its own stability. It is not possible to stand on smooth ground to convey water with this pump.
  • the outlet opening which goes out laterally from the upper part of the housing, additionally reduces the stability due to the top heaviness with the hoses to be attached.
  • a specially encapsulated submersible pump is known from AU-B422521, which sucks in the water from the side and releases it via outputs in the upper housing part upwards or to the side. Due to the lateral suction surface of the entire pump height, this pump only pumps when the housing is completely below the water level. Due to the exits provided exclusively in the upper part of the housing, to which the discharge pipes or hoses are to be connected, the pump is top-heavy and does not offer a firm stand, which would be necessary for pumping out low-level ground water, whereby the suction opening should be directed towards the ground.
  • the invention has for its object to provide a submersible pump of the type mentioned, when using it, regardless of the external circumstances, an optimal stability is guaranteed on the stand, and which can also be used in extremely narrow containers, the inner diameter of which is only slightly larger is the outer diameter of the submersible pump.
  • the line for discharging the pumped water can be connected either laterally or at the top in accordance with the prevailing external conditions. This reduces the risk of the submersible pump tipping to a minimum, even on uneven or flexible ground.
  • the submersible pump designed according to the invention can be placed in extremely narrow containers, the clear inner width of which need only be slightly larger than the outside diameter of the submersible pump. This is achieved by routing the connecting cable at the top. It is also conceivable that a line is connected to both outlet connections, so that either two consumption points can be supplied or a correspondingly doubled throughput is achieved.
  • the two stacked outlet connections are located on one side of the housing, so that simplified flow guides result in the interior of the housing. Since the first outlet connection is relatively deep on the housing side, the weight, the dynamic forces and possibly tensile loads in the line act in relation to the base with a desirably small lever arm, thereby preventing the submersible pump from tipping over undesirably.
  • connection flanges can not only be used for tight connection of the outgoing line.
  • the measure recognizable from claim 6 is also expedient, since the outlet connection which is not required in each case can thus be opened in a simple manner and the other can be closed.
  • the flanges alternately fit on the flanges of the outlet connections, so that no special accessories are required, but the submersible pump can be converted to the respective type of use directly at the construction site.
  • the feature of claim 8 is also essential.
  • such a design can be easily implemented in terms of production technology, since the tube and the connections can be molded in from the outset.
  • the capsule housing of such a submersible pump is subjected to considerable external loads in the often rough operation on a construction site.
  • the capsule housing is therefore ribbed on the outside to improve the structural strength and also to increase the robustness.
  • the ribbing has the additional effect of heat dissipation to the outside. Since the tube integrated into the housing side represents an exposed zone as far as shocks or impacts are concerned, it is expedient if the tube is included in the ribbing according to claim 9 and is therefore protected against damage.
  • the capsule housing is made of plastic or a die-cast, the outlet connections can be integrated particularly easily.
  • a submersible pump 1 according to FIG. 1, which can be used for pumping or pumping clear and dirty water for the home and garden, yard and construction site, has a capsule housing 3 made of plastic or die-cast with horizontally extending reinforcing ribs 4, and a lower part 2 with suction part and on the top 5 a closure cover 6.
  • the closure cover 6 and the lower part 2 are screwed to the capsule housing 3, for example.
  • the top 5 is spanned by a handle 7, the two ends of the bracket are releasably attached to the capsule housing 3 with fastening screws 8.
  • the capsule housing 3 has an essentially flat housing side 3a and three curved housing sides 3b, the ones lying behind in FIG. 1 not being visible.
  • a tube 9 is structurally integrated into the housing side 3a, which runs behind the outside of the housing side 3a upwards and leads to a second outlet connection 10 which is designed in the form of a flange 10a which comprises an outlet opening.
  • the upper side of the flange 10a lies approximately at the height of the upper side of the housing 3.
  • a further flange 11 with fastening screws 12 is fixed on the flange 10a, which in extension of the outlet opening or the tube 9 has a connecting piece 13 with an internal thread 14 to connect a line.
  • a first outlet port 15 which is defined by a flange 15a integrated into the housing side 3a.
  • a further, flat flange 16 is fixed with fastening screws 12 on the flange 15a, which acts as a closure cover 17 for the opening of the outlet connection 15.
  • the lower part 2 which defines the standing surface 2a for the submersible pump 1 on the ground, has feet 18, 20 and inlet openings 19 for sucking in the water.
  • the switching line 22 of a float switch 21 is fastened with a clamp 23, with which the inner pump part, not shown, of the submersible pump 1 is started as soon as the water level around the submersible pump exceeds a certain height.
  • the float switch 21 and the actuation of the inner pump part by it are known and therefore need not be explained in more detail.
  • the flanges 11 and 16 can expediently be interchanged so that the first outlet connection 15 can then be used to connect a line, while the second outlet connection 10 is then closed. It is also conceivable that both outlet connections are opened so that two lines can be connected for two consumers or for a doubled throughput.
  • the standing arrangement of the submersible pump 1 in a well shaft 24 with a horizontal bottom 25 can be seen from FIG.
  • the handle 7 is attached here via a fuse 27 to a cross member 28 of the well shaft.
  • the first outlet connection 15 is closed here as in FIG. 1, while the second outlet connection 10 is closed with the flange 11 a line 26 for a consumer 30 is connected.
  • the submersible pump 1 with this arrangement of the line 26 can also be introduced into a narrow shaft which is only slightly larger than the external dimensions of the submersible pump 1 with this arrangement of the line 26.
  • the submersible pump 1 is inserted in a wide bottom recess 29 and is at the bottom with its lower part 2.
  • the second outlet connection 10 is closed with the flange 16, while the first outlet connection 15 with the flange 11 allows the line 26 to be connected.
  • the line 26 leads away very close to the lower part 2 and can therefore be supported on the bottom of the recess 29 or cannot exert any significant tipping moment on the submersible pump 1.
  • FIGS. 3 and 3 do not emphasize this, the submersible pump 1 can of course be equipped with the float switch 21 from FIG. 1 in order to switch on and off automatically when the water level reaches a certain height.
  • the flange 11 advantageously has a standardized internal thread connection, for. B. 1.25 inches for versatile connectivity. If the capsule housing 3 is made of plastic or printed material, the total weight of the submersible pump is expediently low.
  • the submersible pump 1 as a stationary pump, for. B. is used in a basement drainage system, which has only a limited height, it is advisable to omit the handle 7.
