Definitions

  • the invention relates to a magnetic coupling pump.
  • Magnetic clutch pumps use the attraction and repulsion forces between permanent magnets in both coupling halves for non-contact and slip-free torque transmission.
  • the drive power is transmitted by an electric motor via a drive shaft, which is connected to an outer rotor, on a pump-side magnets bearing rotor (inner rotor) non-contact and slipping.
  • the rotor drives an impeller via a pump shaft.
  • the pump shaft is supported by a lubricated by the fluid flow storage in the housing of the pump. Between the two rotors a split pot is arranged. The split pot separates the conveying fluid from the environment.
  • magnetic coupling pumps In the case of magnetic coupling pumps, the delivery fluid is therefore separated from the environment exclusively by means of static seals, so that leakage of the delivery fluid into the environment is prevented particularly reliably. Therefore, magnetic coupling pumps are often used in the field of chemistry and petrochemistry.
  • the storage is lubricated in the case of magnetic coupling pumps by the pumping fluid of the pump, wherein a partial flow of the conveying fluid required for this purpose is taken from the impeller chamber at a point of high pressure, which increases undergoes lubricating storage and passes through the bearing in the impeller chamber and in the enclosed by the split pot clutch chamber. Through a drainage hole, which connects the clutch chamber with a low pressure point in the impeller chamber, the delivery fluid is returned to the impeller chamber.
  • the conveying fluid emerging into the clutch chamber via the bearing simultaneously cools the containment shell and dissipates the heat generated there by eddy currents.
  • a magnetic coupling pump according to the invention comprises:
  • the clutch chamber is (almost) closed fluid-tight with respect to the impeller chamber.
  • the magnetic coupling pump according to the invention has the advantage that sufficient lubrication of the bearing is ensured even over a relatively long period of time when the pump is operating in dry running and no further conveying fluid can be conveyed through the channel for storage.
  • the clutch chamber is closed fluid-tight with respect to the impeller chamber, i. at most, a low return of the Forderfluids from the clutch chamber is carried out directly into the impeller, the fluid flows from the storage area much slower.
  • the storage remains sufficiently lubricated over a much longer period, even if no delivery fluid is replenished via the channel.
  • the delivery fluid passes through the storage not only in the clutch chamber, but also in the impeller chamber.
  • the delivery fluid also passes back into the impeller chamber without the usual emptying of the clutch chamber from emptying, so that a circulation of the Forderfluid serving as a lubricant during normal operation of the invention Pump is guaranteed.
  • the conveying fluid exiting via the bearing in the impeller chamber is replenished from the coupling chamber.
  • the delivery fluid present in the clutch chamber is sufficient to maintain lubrication for an extended period of time (up to an hour or more) until the pump runs dry and the pump is turned off.
  • the containment shell consists of a non-metallic material.
  • the reduced by the inventive closure of the clutch chamber with respect to the impeller circulation of the Forderfluids is thus unproblematic in terms of cooling in combination with the non-metallic material of the split pot.
  • the containment shell of technical ceramics or plastic, such as PEEK.
  • Plastic cans are characterized by their low weight and low sensitivity to breakage and easy handling.
  • Canned ceramic cans e.g., SiC
  • At least one throttle element is provided which throttles the flow of the Forderfluids through the channel.
  • the throttle element can, for example, cover or close the inlet-side opening of the channel to the impeller chamber.
  • the throttle element may, for example, be disc-shaped and attached to the ring, so that it partially covers the opening of the channel.
  • an annular disk fastened to the ring can form the throttle element, which at the same time closes an emptying bore formed in the ring, which is originally provided for connecting the coupling chamber to the impeller chamber.
  • the parts of a conventional magnetic coupling pump with little effort for a pump designed according to the invention are used. Only the attachment of the additional annular disc is required, preferably in combination with the use of a non-metallic containment shell.
  • the annular disc partially closes the channel to reduce the cross section for throttling the fluid flow, and the drain hole completely.
  • the throttling element is disposed in the upstream so that the flow of the conveying fluid through the channel is throttled.
  • the throttle element is for this purpose designed such that particles must move radially inwardly against the centrifugal force in the channel to get into the clutch chamber.
  • the partial flow of the delivery fluid, which passes from the impeller chamber to the bearing for lubrication of the bearing in the clutch chamber, is significantly reduced by the throttle element, whereby the entry of particles is reduced in solids loading of the fluid flow into the containment shell.
  • the pump shaft has no fluid connection between the impeller chamber and the clutch chamber.
  • the pump shaft has an axial through hole to ensure sufficient circulation of the conveying fluid from the pressure side of the impeller chamber via the bearing in the coupling chamber and through the pump shaft back to the suction side of the impeller chamber for the purpose of sufficient cooling of the split pot. Due to the lack of fluid connection via the pump shaft, the circulation is inventively reduced and thereby achieved that the clutch chamber remains filled with conveying fluid in the dry run for as long as possible in order to maintain the lubrication.
  • the pump shaft may be formed as a solid body. But it is also possible that the pump shaft is designed as a hollow shaft which is closed at least one end.
  • a preferred embodiment provides that a return of the delivery fluid from the clutch chamber into the impeller chamber via the storage.
  • the return of the delivery fluid from the Coupling chamber in the impeller can be carried out exclusively on the storage. As a result, adequate lubrication of the storage over a longer period is ensured, even if the pump operates in dry running and no further fluid can be conveyed through the channel for storage.
  • the return of the delivery fluid from the clutch chamber in the impeller chamber is in the storage area, so that the storage is sufficiently lubricated over a much longer period of time, even if no delivery fluid is replenished via the channel.
  • the delivery fluid thus returns to the impeller chamber, so that a circulation of the delivery fluid serving as a lubricant during normal operation of the pump according to the invention is ensured.
  • dry running the conveying fluid exiting via the bearing in the impeller chamber is replenished from the coupling chamber.
  • the delivery fluid present in the clutch chamber is sufficient for a longer period of time (up to an hour or more) to maintain lubrication.
  • the pump can be switched off without damage, as soon as the dry running of the pump is noticed.
  • the return of the conveying fluid from the clutch chamber into the impeller chamber via a radial bearing gap in the storage takes place.
  • the radial bearing gap is preferably located between the bearing elements of the bearing so that lubrication is ensured even when the pump is running dry.
  • the radial bearing gap is arranged impeller side in the storage.
  • the radial bearing gap throttles the return of the conveying fluid from the clutch chamber into the impeller chamber.
  • the radial bearing gap in the impeller-side radial bearing of the bearing preferably has no lubricating groove in order to further restrict the return of the conveying fluid. Since rinsing of the bearing does not occur when the feed fluid is loaded with solids, the entry of particles into the Clutch chamber can be reduced by the throttle element described above and below.
  • lubrication are arranged on the coupling side in the storage.
  • the coupling-side radial bearing of the bearing may have lubrication grooves, by which a flushing between the bearing elements is ensured. This is especially important in the case of solids loading of the delivery fluid in order to nevertheless ensure a high durability of the storage.
