Definitions
- the invention relates to a submersible pump with a pump chamber, one within the same arranged conveyor and at least one Intake opening with one of the pump chamber in the flow direction upstream collection room in the form of a tub communicates.
- Submersible pumps of this type are known from US Pat. No. 5,205,725.
- the inlet openings to the tub provided there are in Distance to a footprint of the pump and approximately at the height of a Levels in which the intake opening is also located.
- This design is intended to prevent that is usually at the bottom of a container to be pumped out lying dirt is sucked out of the container sump and then too blockage or damage to the pump impeller, which the liquid to be pumped is sucked in centrally and radially outwards emits a pressure chamber which is provided with an outlet port.
- centrifugal pumps such as those in the form of a centrifugal pump from DE U 82 10 587 are known, see a filter below an intake opening in front, which is provided with inlet openings on its circumference.
- Centrifugal pumps can be used as flat suction submersible or drainage pumps be provided.
- the filters tend to clog, if they are placed in the area of a container sump because the Inlets are located in the area of the stand and thus in the tank bottom area are located.
- a submersible pump mentioned type to create, in particular for suction very low liquid level is suitable. Accidental suction of air and pollution should be additional if possible be prevented.
- a submersible pump is the provided at the outset, in which the tub has a circumferential Has side wall with an upper edge which is at a higher level than the suction opening is located and that at least one flow channel is provided is at least one outside the side wall and at a distance leads below the upper edge of the inlet opening.
- the tub surrounds the pump chamber Bottom-closing base plate with the suction opening complete and with a full tub, there is a guarantee that the Suction opening protrudes completely into the liquid. A suction of air is prevented. Nevertheless, the inlet openings of the pump lie in the immediate area of the bottom of a tank or the like, so that the pump according to the invention even at a very low liquid level can be used effectively.
- the new submersible pump can also be used in this way design that the inlet openings for the liquid are also clear are below the level at which the suction opening is located. You can also run at the bottom of the tub, which is parallel to the rest of the Level of the pump, i.e. parallel to the installation area on the tank bottom is.
- the size of the inlet openings of the pump is adjustable. Then it will achieved an embodiment between a flat suction and a conventional mode of operation as a submersible pump.
- the Flat suction function can be the side inlet openings for the suction Liquid can be kept very low, for example only a few millimeters or less than a millimeter above the installation level protrude. Due to the then small cross section with a correspondingly higher one Flow resistance can be lower than in the conventional mode of operation with a larger inflow cross section and lower flow resistance. Nevertheless, there is a suction possible at extremely low water levels.
- the cross-sectional adjustment of the inlet openings can an adjustable and / or removable component is provided be, for example, as a parallel to a vertical pump center axis movable component, preferably as a housing ring can be trained. It is also possible, the size of the inflow openings by feet, the outside of the pump housing are adjustable in their position.
- the design according to the invention also enables suction very flat water levels with high suction after a start-up phase.
- the start-up phase can advantageously be shortened or avoided, if, for example, the tub provided according to the invention from the outside against the pump flow direction before commissioning is filled through the pump chamber.
- the submersible pump 11 has a Pump housing 12.
- This pump housing 12 consists essentially from an upper housing part 13, a lower housing part 14 and a Outlet port 15.
- the pump housing 12 can be made of plastic, however also be made of other materials.
- the upper housing part 13 is provided with a handle 16, the one Handling of the submersible pump 11 is facilitated. It is also possible that Pump with a float (not shown) to the Pump in the usual way at high water levels, which is the height exceed the pump.
- the upper housing part 13 is with the lower housing part 14 via screws 17 connected. However, it is also possible to connect to others Way to manufacture. Between upper housing part 13 and lower housing part 14, a sealing ring 18 is provided. This is a little wider than the upper part of the case 13 designed lower housing part 14 is adjacent to one Provided upper outlet part 15, which is also about another seal 18a is connected to the lower housing part.
- the pump chamber 20 is down to a footprint 21 of the submersible pump 11 completed by a base plate 22.
- the conveyor 24 is in the embodiment a wheel driven by an electric motor 25 Centrifugal pump or a turbine. That shown in the embodiment The centrifugal pump wheel is at the transition from the upper part of the housing 13 driven to the lower housing part 14 arranged motor 25.
- the energy supply the motor 25, which is expediently an electric motor, can be done from the outside via cable connections, which is schematic in Fig. 1 are indicated next to the handle 16.
- the motor 25 has one on its side facing the base plate 22 short drive shaft 26 to which the impeller 27 of the pump is attached. How 3 shows, this impeller 27 has a plurality of arcuate curves Guide vanes 56 through which the liquid in a known manner in an Cross-section finger-shaped pressure chamber protruding from the pump chamber 20 28 is promoted. From there, the liquid gets into the outlet nozzle 15 and is removed from there.
- suction opening 29 There is an essentially circular suction opening in the base plate 22 29.
- the central axis of this suction opening coincides with the pump axis 39 together.
- the suction opening 29 opens into a below the base plate 22 arranged tub.
- a filter 35 Located in front of the suction opening 29 a filter 35 in the exemplary embodiment, which is used for filtering Mud, dirt particles or the like that is used in the suction Liquid.
- the tub 30 encloses the part of the Base plate 22 which receives the impeller 27 substantially.
- the tub 30 consists of a trough bottom 32 and one essentially up to to an upper edge 34 extending vertically upwards Side wall 31.
- the upper edge 34 is preferably on a higher Level as the impeller 27.
- the tub volume that down from the Trough bottom 32 and is delimited from the outside by the side wall 31, is provided with the reference number 33.
- the upper edge 34 of the side wall 31 lies higher than the base plate 22 and higher than its suction opening 29. When the tub 30 is full, this prevents air from the impeller 27 can be sucked in, which affects the suction power could lead.
- the tub can be used when the pump is used for suction should be used at very low liquid levels - what follows is explained in more detail - before commissioning from the outside through the outlet connection 15 via the pump chamber 20 with liquid be filled, so that from the start of operation the full suction power is available, regardless of how high the suction Is liquid level.
- the submersible pump 11 has inlet openings 36 through which the suctioned Liquid gets inside the pump.
- the inlet openings 36 are located depending on the embodiment at different points on the pump housing, as will be described with reference to the further FIGS. 4 to 7 becomes.
- the Inlet openings 36 formed by a gap between the lower edge of the lower housing part 13 - for reasons of assembly ability the impeller is provided in two parts with a bottom part attached at the bottom, which surrounds the tub 30 - and a bottom surface 43 is formed which the submersible pump 11 is attached.
- the pump is in the embodiment with three in height adjustable feet 54 provided for quick adjustability can also be arranged rotatably for predetermined gap heights and thereby with different peripheral areas on the bottom surface 43 can get up.
- the inlet openings 36 form the entrance for at least one flow channel 37, over which the sucked liquid flows into the tub 30.
- Liquid arrives initially in an ascending section 38 which extends outward from the Lower housing part and bounded inwardly by the side wall 31 of the tub is.
- the flow channel then continues in one in FIG. 1 to 3 not particularly recognizable section, which over the upper edge 34 the side wall 31 leads away and then the liquid in the sense of Arrow 41 between base plate 22 and side wall 31 in the tub volume 33 ends.
- the footprint 21 of the submersible pump 11 is covered by those previously mentioned Feet 54 formed. These are each from the pump housing independent component designed and height adjustable attached to it.
- the feet 54 themselves are asymmetrical and on one from the pump housing 12 projecting pin 50 rotatably mounted. By rotating the feet 54 can be due to their asymmetry Height of the underside of the submersible pump 11 set above the bottom surface 43 become. A gap 46 with different heights can therefore be set, depending on whether the pump in its "flat suction" function or in its Function "diving operation" is set.
- the submersible pump 11 essentially has a flattened pear-shaped cross section.
- Pump housing 12 At the extent of Pump housing 12 are several in approximately regular intervals essentially vertical channels 37, previously mentioned have been arranged, the outside in associated entry openings lead.
- the feet 54 are in the manner of a tripod on the pump housing arranged.
- FIGS. 4A and 4B and in the other figures Embodiments of the submersible pump 11 are the same for the same parts Reference numerals used. Have different configurations received additional reference numbers.
- the Submersible pump 11 has a circumferential housing foot 42, which over the The circumference distributes a plurality of contact surfaces and between them Has recesses as inlet openings for the liquid to be sucked.
- the contact surfaces define the level 21 of the submersible pump 11, with which this on a liquid-covered bottom surface 43 gets up.
- the submersible pump 11 can also be used with the tub floor 32 stand on the floor surface 43.
- the housing foot 42 forms the lower edge of the ascending section 38 of the flow channel 37 delimiting outer wall 44.
- a housing ring 45 is adjustable in height arranged, for example by rotation and guidance in a backdrop Groove, and is held on the outer wall 44.
- the housing ring 45 4A is in its lower position in the illustration according to FIG. 4A 45 (L) so that between its bottom edge and the bottom surface 43 only a narrow gap as an inlet opening 36 for liquid to be sucked in remains. Liquid can therefore reach the level of the top edge of the Gap are suctioned off.
- the gap can, as already mentioned at the beginning, a height of only a few millimeters or less if necessary to have.
- housing ring 45 for example by rotation, in the in Fig. 4B shown upper position 45 (H) shifted, so there is an opposite the gap of Fig. 4A much larger inlet opening that the Openings in the housing base 42 corresponds.
- the housing ring 45 is opposite the outer wall 44 sealed by a sealing ring 48, so that also in the flat suction position according to FIG. 4A there is no suction behavior impairing secondary air flow between outer wall 44 and Housing ring 45 can occur.
- This Foot insert 47 can be, for example, with a web or with projections snap into an annular groove in the outer wall 44.
- the foot insert 47 has the shape of its side facing the bottom surface 48 or by its relative vertical position to a housing foot on his outer circumference a small gap 46 as an inlet opening for suction Liquid on.
- the foot insert 47 is opposed by a sealing ring 49 a side air flow between the side wall of the foot insert 47 and Sealed outer wall 44.
- the foot insert 47 is removed, it is expanded the inlet opening opposite the gap 46 to the much larger ones Openings 50 in the housing foot 42.
- the submersible pump 11 stands with its trough bottom 32 on the bottom surface 43 and the gap 46 between the bottom surface 43 and the lower edge of the outer wall 44 now forms the inlet opening for a flat suction.
- the pump can also be used the lower edge of the outer wall 44 as a housing foot 42 on the bottom surface 43 stand up, with recesses or openings on the circumference form the inlet openings for the flat suction.
- Fig. 6A shows a housing ring 51 being pushed on from below, the openings 52 between the webs which stand on the bottom surface 53, has, which is much larger compared to the aforementioned gap are.
- an extension of the Inflow opening for example, by plugging or other fastening of individual spacing elements, by vertical displacement, in particular turning a ring running in an inclined guide or by adjusting, in particular swiveling, permanently with the Pump housing or its outer wall 44 connected spacers can be achieved, which is instead of the housing ring 51 on the Support the floor area.
- FIG. 7A and 7B is such an arrangement, which is otherwise the Fig. 6A and 6B.
- the spacers 53 are in FIG. 7B for the flat suction function upwards and in Fig. 7A for the usual submersible pump function pivoted down.
