Definitions

  • the invention relates to a centrifugal pump impeller with a non-metallic impeller part and a metallic hub part connected to the impeller part, which is arranged on a shaft, with a releasable connection between the impeller part and the hub part, the impeller part and the hub part being releasably connected to one another via driver elements.
  • Centrifugal pump impellers which are made entirely of metal, are usually attached to a shaft by pushing their hub bore onto a shaft end and pressing them against a collar of the shaft using a nut. Such a fastening method is disadvantageous in the case of centrifugal pump impellers according to the preamble of the invention, since they comprise a non-metallic impeller part. Many non-metallic materials, such as polymer casting or plastic, tend to flow under pressure.
  • centrifugal pump impeller which comprises a non-metallic impeller part and a metallic hub part.
  • Hub parts are components that are arranged on and surround the drive shaft.
  • the hub part is provided with a central receiving opening.
  • the receiving opening has a thread into which the shaft end can be screwed.
  • the impeller part made of plastic is molded onto the hub part.
  • the hub part has a ring which is perforated and is extrusion-coated with the plastic material of the impeller part.
  • This centrifugal pump impeller has a non-detachable connection between the hub part and the impeller part.
  • DD 18 758 describes a completely different way of attaching impellers made of a ceramic material.
  • this method does not use a hub part.
  • An intermediate flange is used instead of a hub part.
  • This intermediate flange is arranged between the shaft end and the impeller.
  • the impeller and the intermediate flange are drilled.
  • a screw bolt is arranged in the bore and has a head at one end and a thread at the other end, onto which a nut is screwed.
  • the impeller and the intermediate flange are clamped against each other by screwing a nut onto the thread.
  • the intermediate flange is in turn connected to the shaft by means of a screw connection.
  • the shaft is formed at one end with a flange ring, in which the bores for the screw connections between the flange and the shaft are arranged.
  • This construction of the attachment using an intermediate flange is very complex and bulky, since, in contrast to a hub part, the intermediate flange is not arranged on the shaft, but rather is located at the shaft end between the shaft and the impeller.
  • the DE 2 319 463 describes a rotor for a pump for cooling internal combustion engines.
  • the rotor consists of a metallic hub part that is pushed onto the shaft in a press fit.
  • the impeller part is poured onto this metallic hub part.
  • the impeller part consists of a thermosetting resin mixture. With this construction, too, a permanent, non-detachable bond is produced between the hub part and the impeller part.
  • the DE 76 10 913 describes a centrifugal pump with a plastic impeller.
  • a circular disk made of a metal is arranged in the hub area of the impeller.
  • the impeller has a metal bush for storage, to which the circular disc is attached.
  • the circular disc is completely embedded in the plastic of the impeller. There is therefore an inseparable unit between the plastic impeller and the metallic circular disc.
  • a centrifugal pump impeller is known with a non-metallic impeller part and an associated metallic hub part, wherein between Impeller part and hub part is a detachable connection.
  • the impeller part is fixed to the hub part by means of a plastically deformable part.
  • the WO 2013/000032 A1 discloses a ceramic impeller with a conveying part, an inner back vane part and an outer back vane part, the conveying part comprising the main blades for conveying the medium.
  • a metallic hub is arranged between the conveying part and the inner back vane part.
  • liquid polyurethane resin is poured between the hub and the conveying part, which, after cooling, is used to connect the conveying part to the hub and to dampen impacts.
  • the inner back vane part is screwed onto the conveying part by means of screws.
  • the DE 895 250 C. describes a ceramic impeller on the back of which a hub is formed, onto which a metallic sleeve is applied, which serves to connect the impeller to its drive shaft.
  • the object of the invention is to provide a centrifugal pump impeller which can be inexpensively repaired when wear and tear occurs. In addition, the repair work should be carried out quickly and inexpensively.
  • the centrifugal pump impeller should be able to be manufactured at a low cost and be of high quality.
  • driver elements each have a sleeve and a connecting element and the sleeves are arranged in recesses on an end face of the impeller part.
  • the non-metallic impeller part is therefore not cast around the metallic hub part. Instead, the impeller part and the hub part are detachably connected to one another via driver elements.
  • the hub part is preferably a one-piece metallic component.
  • the driver elements are designed in several parts. It is preferably a two-part design. According to the invention, the driver elements each have a sleeve and a connecting element with which a reliable screw connection can be produced.
  • the sleeves are arranged in depressions on one end face, in particular the shaft end face, of the impeller part.
  • the depressions are preferably bores which are made in the non-metallic impeller part, round bores being particularly suitable.
  • a plurality of bores can be made on the end face, for example in the region of the carrier plate, of the impeller part along a circular arrangement. It proves to be advantageous if the number of bores corresponds to the number of blades of the impeller part.
  • the depressions are preferably introduced at positions of the carrier plate at which the blades engage.
  • the sleeves of the driver elements are placed in the indentations and fastened there.
  • the sleeves can, for example, be pressed and / or glued into the depressions. The sleeves sit in the recesses of the impeller part without play.
  • the sleeves are cast on one end face of the impeller part. This eliminates the need for drilling.
  • the sleeves have a suitable anti-rotation device.
  • the connecting elements are arranged on a ring of the hub part and at least partially engage in the sleeves.
  • the connecting elements are preferably screwed into the sleeves. This creates a reliable connection between the impeller part and the hub part.
  • the connecting elements are preferably screws.
  • the sleeves are provided with an internal thread, into which the external thread of the connecting elements designed as screws engages.
  • the screws preferably have a conical shoulder and are placed in bores on the ring of the hub part and then screwed into the sleeves.
  • the bores have countersinks which are designed to be complementary to the cone approaches. This creates a backlash-free or largely backlash-free construction in which the individual parts of the driver elements are detachably connected to one another.
  • Another advantage of the construction according to the invention is that no more stresses occur in the centrifugal pump impeller according to the invention, which occur in conventional centrifugal pump impellers made of polymer casting due to the different thermal expansion values of the impeller part and the hub part.
  • the hub part preferably has a projection which projects into the impeller part.
  • This projection is designed as a hollow cylinder and surrounds the shaft. This ring is connected to this hollow cylindrical projection of the hub part.
  • the ring of the hub part is aligned parallel to the shaft-side end face of the impeller part and lies against the end face of the impeller part.
  • this ring is adjoined by an extension which is also hollow-cylindrical and thus surrounds the shaft.
  • the metallic hub part preferably has on its inside at least one groove into which a feather key engages, which establishes a connection between the shaft and the hub part for torque transmission.
  • a disc is arranged on a shaft end for fixing the impeller part.
  • the non-metallic impeller part preferably has a circular recess on the flow side, into which the disk is positioned.
  • the disk has bores, for example along its circumference.
  • the disc is attached to the shaft end by means of suitable screws. As a result, the hub part and the impeller part are braced against each other.
  • centrifugal pump impeller When assembling the centrifugal pump impeller, proceed as follows: First, the metallic hub part and the non-metallic impeller part are connected. The pre-assembled two-part centrifugal pump impeller is pushed onto the shaft end. Then the impeller part and hub part are braced against each other by means of the disk which is attached to the shaft end.
  • a cap is preferably arranged on the flow side on the disk. Since the cap comes into contact with flow medium, it is usually made of a corrosion-resistant material.
  • the impeller part consists of a ceramic material.
  • a ceramic-plastic composite is preferably suitable for this. It proves to be particularly advantageous if this comprises silicon carbide particles which are arranged in a polymer matrix.
  • the metallic hub part is preferably made of a rustproof duplex cast steel.
  • Fig. 1 shows a centrifugal pump impeller 1, which is arranged in a housing 2 of a centrifugal pump.
  • the housing 2 comprises a suction opening 3, through the medium is sucked in and conveyed by means of the centrifugal pump impeller 1 in the direction of an outflow opening 4 and then leaves the centrifugal pump.
  • the centrifugal pump impeller 1 is arranged on a shaft 5.
  • the shaft 5 is set in rotation by a motor, not shown.
  • the torque is transmitted to the metallic hub part 8 via two feather keys 6 and to the non-metallic impeller part 7 of the centrifugal pump impeller 1 via the driver elements 12.
  • the centrifugal pump impeller 1 consists of a non-metallic impeller part 7 and a metallic hub part 8.
  • the non-metallic impeller part 7 is made of a ceramic-plastic composite material in which silicon carbide particles are embedded in a polymer matrix.
  • the hub part 8 is made of a rust-free duplex cast steel, which has a ferritic-austenitic structure.
  • the non-metallic impeller part 7 is made in one piece and is produced in the casting process. It has a carrier plate 9, on which blades 10 are molded. In the exemplary embodiment, it is a radial centrifugal pump impeller.
  • Fig. 2 shows a perspective exploded view of the centrifugal pump impeller 1 with the end of the shaft 5.
  • the non-metallic impeller part 7 has depressions 11.
  • the depressions 11 are bores which are introduced into the impeller part 7 after or before they have completely hardened or are then finished if they were already pre-cast during manufacture.
  • Fig. 3 shows that engaging elements 12 engage in the recesses 11 in the assembled state.
  • Each driver element 12 consists of a sleeve 13 and a connecting element 14.
  • the sleeve 13 is a hollow cylindrical body which is closed on one end face.
  • Each sleeve 13 has an internal thread.
  • the connecting element 14 is designed as a screw which has an external thread.
  • the sleeves 13 can be cast in on the shaft-side end face of the impeller part 7.
  • Fig. 2 shows that the hub part 8 has a ring 15 which is provided with a plurality of bores 16 along its circumference.
  • connecting elements 14 are inserted into the bores 16 and screwed into the sleeves 13, which are arranged in the recesses 11, and secured.
  • screws 20 can also be screwed into additional threaded sleeves or threaded bores 21 provided in the non-metallic material of the impeller part 7 and serve, for example, as a transport lock or assembly aid if the sleeves 13 are not pressed or glued into the recesses 11 are.
  • the pre-assembled centrifugal pump impeller is pushed onto the end of shaft 5.
  • the shaft 5 is connected in a rotationally fixed manner to the hub part 8 via the feather keys 6, the feather keys 6 engaging in grooves 17 of the hub part 8.
