Definitions

  • the invention relates to a tubular housing pump, the running and guiding device of which is connected to a riser pipe, a shaft arranged inside the riser pipe driving the running device being connected to a drive arranged above the riser pipe, a multi-part lantern transmitting the weight of the drive into a foundation, an outer bearing element known per se is provided on the riser pipe and / or on the manifold and the riser pipe opens into a pressure-tight manifold housing.
  • tubular casing pumps are known, for example, from the KSB centrifugal pump lexicon, page 262, 3rd edition, July 1989. They are usually designed in one stage and serve to convey large quantities of liquid, an axial or semi-axial wheel often being used as the impeller.
  • a guide device is arranged downstream of the impeller, which opens into one or more risers, with the aid of which a conveyed fluid is removed.
  • a shaft driving the impeller is arranged within the risers.
  • a multi-part lantern arranged on an upper first foundation level absorbs the forces of the drive. The weight of manifolds,
  • the riser pipe, riser pipe parts, the shaft and the weight of a suspension pipe enveloping the shaft and carrying the running and guiding device are received on a lower second foundation level.
  • a manifold inlet flange with a larger diameter and resting on a crossbeam is formed in the transition area between the riser pipe and the manifold.
  • supports for the guide bearings of the shaft are arranged therein.
  • the tubular casing pump is designed with a pull-out running gear.
  • the lantern and possibly a device for an adjustable impeller the entire running gear is lifted out of the riser pipe. This saves opening pipes that are attached to the pump connection on the pressure side.
  • Page 222 of the KSB centrifugal pump lexicon shows an embodiment of a tubular casing pump in which an inlet nozzle is used instead of a suction line.
  • the tubular casing pump is suspended swinging freely in an inlet chamber or in an inlet basin.
  • their vibration behavior can sometimes lead to unfavorable resonance vibrations, which adversely affect the running behavior of the tubular casing pump.
  • the pump components are designed as cast structures that have good internal damping with regard to vibrations.
  • JP 62-107299 Another measure to solve such vibration problems is shown in JP 62-107299.
  • a so-called borehole pump with several stages is disclosed therein.
  • Such borehole pumps are very long and thin. In comparison to tubular casing pumps, they can only deliver small amounts to very high delivery heights. 4 and 5, known solutions are shown which provide support in the region of the pump stages with the aid of crossbeams or intermediate decks.
  • the invention is based on the problem of improving the vibration behavior of tubular housing pumps with the simplest of means and with reduced manufacturing expenditure.
  • the solution to this problem provides that a force-transmitting receptacle, guide and seal for the outer bearing element is provided in a base plate of a pressure-tight manifold housing. With this solution, the entire weight of the riser pipe is introduced via the bearing element in the shortest possible way into the bottom plate of the manifold housing, which creates the possibility of pulling out the pump part together with the riser pipes through the manifold housing. If the tubular casing pump is installed on only one foundation level, this is also the level that also absorbs the forces of the drive.
  • the length of the pump part to the outer bearing element and the length of the structure above the outer bearing element are only taken into account for the vibration calculation of the tubular housing pump, starting from the bearing level of the bearing element in the base plate.
  • the non-rotating pump part including the connected riser pipe and elbow parts form a pendulum system from a vibration point of view
  • the rotating part consisting of impeller with shaft
  • these two pendulum systems are primarily to be evaluated mathematically.
  • the base plate is a component of the multi-part lantern or that the base plate is a component of a pressure-tight manifold housing integrated in the lantern.
  • the vibration length of the stationary pump part can be defined in a simple manner.
  • the pendulum length is assumed to be the length up to the bearing for the absorption of the axial forces.
  • the drive is removed from the lantern in a manner known per se and then, after opening a pressure cover arranged on the manifold housing, the entire pump part including the manifold, riser pipe, shaft, impeller and all other internals are lifted out of the manifold housing.
  • a further embodiment provides that the shaft, which is connected to the running gear to transmit forces, is mounted in the lantern and above the pressure opening of the pump part. This results in a length to be taken into account when calculating the vibration behavior of the rotating parts, which is greater than the length of the riser pipe with the connected pump part.
  • Fig. 1 shows a tubular casing pump in section
  • Fig. 2 + 3 is an enlarged view of the storage of the pump part and the Fig. 4 shows an embodiment in a multi-stage design.
  • the multi-part lantern 2 consists of a motor lantern 2.1, which surrounds an axial bearing 5 of a shaft 6 and its shaft coupling 7.
  • the motor lantern 2.1 is supported by an intermediate lantern 2.2 on a manifold housing 2.3 that is pressure-tight in the lantern 2.
  • the weight forces of the motor 1 are guided into the foundation 3 from its base plate 2.4.
  • the motor lantern 2.1 can also be designed as a so-called slip-on lantern, which is placed over the intermediate lantern 2.2 and the manifold housing 2.3 and surrounds it with a larger diameter.
  • slip-on lantern also transfers the forces of the motor 1 directly into the foundation 3 in the plane of the base plate 2.4.
  • the pressure-tight manifold housing 2.3 and the intermediate lantern 2.2 are relieved of the weight of the engine.
  • the liquid-carrying pump part 4 consists of two interconnected riser pipes 9, in which the bearings 11 of the shaft 6 are held by means of guide elements 10.
  • an impeller 12 is arranged in the riser pipe 9 at the beginning of the pump part 4 seen in the flow direction.
  • the riser pipe 9 also partially takes on the function of a pump housing 8, since the flow-carrying internals 13 of the pump part 4 are also arranged therein.
  • Impeller 12, shown here in a semi-axial design, and flow-carrying internals 13 can also be part of a separate pump housing, which is connected to a riser pipe 9.
  • the shaft 6 As a result of the formation of the shaft 6 as a force-transmitting component for the illustrated impeller 12, its weight is also held by the shaft 6.
  • the pump part 4 is fastened to a pressure cover 14 of the manifold housing 2.3 and to the base plate 2.4.
  • a fluid conveyed by the impeller 12 through the riser pipes 9 flows through a manifold 15 connected to the riser pipes 9, which is removably arranged in the manifold housing 2.3.
  • the elbow 15 directs the fluid into a pipeline to be connected to the elbow - not shown here.
  • Such a pipeline is fastened in a liquid-tight manner to a flange arranged on the right-hand side of the manifold housing 2.4 in the drawing.
  • the manifold 15 is arranged free-standing in the manifold housing 2.4. There is a gap between an outlet opening of the manifold 15 and the inside diameter of the manifold housing 2.4. This decouples the manifold 15 from the manifold housing 2.4 and facilitates assembly or disassembly work by simply lifting out the pump part 4. No seal is required at the outlet of the manifold 15, since the interior of the manifold housing 2.3 is designed to be pressure-tight and filled with fluid.
  • An outer bearing element 17 is attached to the manifold 15, by means of which the weight of the non-rotating or stationary pump parts is transferred into the base plate 2.4.
  • the bearing element 17 can also be fastened to the riser pipe 9 when it protrudes into the manifold housing 2.3.
  • the location of the attachment depends on the selected size of the manifold 15, the manifold housing 2.4 or an adjacent riser pipe 9.
  • the manifold housing 2.3 is closed in a pressure-tight manner by the pressure cover 14.
  • a short support element 18 connects the manifold 15 to the pressure cover 14 in a force-transmitting manner the pressure cover 14.
  • a shaft seal known per se is arranged for the passage of the shaft 6.
  • the pump part 4 is designed as a welded construction. This even represents an advantage over a vibration-damping cast construction, since the formation of a defined vibration node in the area of the bearing element 17 resting on the base plate 2.4 results in a more controllable vibration behavior.
  • the motor 1 is lifted off the motor lantern 2.1 when the shaft coupling 7 is open. Then the pressure cover 14 is released from the liquid-tight manifold housing 2.3. Due to the support element 18 fastened to the elbow 15, which can also be designed as a tubular element, the weight of the pump part 4 bears on the pressure cover 14 during assembly or disassembly Bearing element 17 passed directly into the base plate 2.4. As a result of the storage, guidance and sealing on the bearing element 17, a decoupling takes place at this force-absorbing point of the base plate 2.4 from a static point of view, as a result of which a vibration node is simultaneously formed for the pipe housing pump.
  • this solution eliminates vibratable components, thereby reducing the number of natural frequencies to be taken into account and thus simplifying the calculation of the natural frequencies. Because the storage of the non-rotating pump parts in the base plate and the omission of an additional suspension tube surrounding the shaft, which was previously necessary, reduces the number of vibratable system parts and improves the vibration behavior of the tubular casing pump. This type of pump suspension thus also forms a defined vibration node for the overall system of the tubular casing pump.
  • the tubular casing pump is designed as a welded construction.
  • This allows a standardized design in which a size of a lantern 2 can be used for different riser pipe diameters.
  • the respective lantern 2 is designed for a maximum diameter of the pump part 4.
  • the width of the opening, in the area of which the outer bearing element 17 rests, is chosen to be so large that it is possible to pull out the components to be passed through, that is to say the largest complete pump part 4 for this manifold housing, including the riser pipes 9.
  • the installation of another bearing element 17 is then necessary.
  • FIG. 2 shown as a half-section, the bearing element 17 is shown in an enlarged representation, which transmits the forces in the base plate 2.4 and the foundation 3 in the shortest possible way.
  • the base plate 2.4 has an opening which is designed to receive the bearing element 17.
  • the illustration in FIG. 2 shows in the base plate 2.4 a conical or conical opening in which the bearing element 17 rests with a corresponding contour in a self-centering and force-transmitting manner.
  • additional sealing elements 19 for example sealing rings, are arranged.
  • liquid escape from the manifold housing 2.3 in the area of the base plate 2.4 is prevented.
  • Fig. 3 shows a modified embodiment of the bearing element 17, which is designed in the manner of an angle ring.
  • the transmission of forces is carried out here by an annular surface 20 which extends in the radial direction, while the centering takes place by means of an adjacent, low-tolerance fitting section 21.
  • the multi-stage pump part 4 is shown in two stages and, in contrast to FIG. 1, has separate pump housings 22, 23 which are interconnected by a riser pipe 9 or riser pipe parts 9.1.
  • the pump housing 8.1 of the second pump stage is connected to the elbow 15 by a shorter riser pipe section 9.1. In this design too, all diameters are selected so that the entire pump part 4 can be passed as a part through the base plate 2.4 without any problems.
