Definitions

  • the invention relates to a pump according to the preamble of the claim 1.
  • the housing of centrifugal pumps usually consist of a or more housing parts that make up the work space or work spaces enclose on the circumference, as well as a lid, through the pump shaft is guided sealed in the housing. Because there are different types of gaskets, the different ones Requirements for the shape of the housing cover it is customary for any one related to one Pump type for sealing type to use a special housing cover provided.
  • the invention is based on the object, a pump of the above constructively simplify this type.
  • the invention provides for this purpose that the lid and the seal housing to be operated with a locking medium Seal contain aligned holes for the barrier medium supply, in the opposite circumferential surfaces the passage opening and the sealing housing therein lead.
  • the aforementioned peripheral surfaces are as mating surfaces engineered and located within the static seal.
  • the invention has recognized on the one hand that due to the aligned Holes in the lid and the seal housing one with Barrier medium to be operated seal the hole in the lid regardless of whether the barrier medium-needy Seal type is used or not.
  • the cover hole is aligned with the corresponding Bore of the seal housing; in the other case, the Dekkelbohrung through the closed executed seal housing blocked.
  • the housing of the pump comprises on the one hand a main housing part 1, the foot 2, the suction nozzle 3 and the discharge nozzle 4 forms, and on the other hand, a housing cover 5, the Main body part 1 on the drive side closes.
  • a bearing housing 6 the two Includes bearing 7 for the shaft 8, which through the lid 5 in the housing is guided and there carries the impeller 9.
  • the housing cover 5 includes a Passage opening 10 which is closed by the seal housing 11 is that in turn holds the seal 12.
  • the Seal housing 11 is in the area of the end faces 13 with bolted to the housing cover 5 and by a suitable sealed static seal.
  • the seal 12 as Mechanical seal 12a formed.
  • FIG. 2 is a Stuffing box packing 12b, which in a chamber of the corresponding Seal housing 11 b axially compressed by means of glasses 14 becomes. It is intended for operation with barrier fluid, through a bore 15 the pump chamber near the pressure side is removed and via a bore 16 in the seal housing 11b, which is aligned with the bore 15, in the packing area arrives. The transition from the bore 15 to the bore 16 takes place in the region of the gap 17 between each other Peripheral surfaces of the seal housing 11b and the housing cover 5 instead, by choosing appropriate dimensional tolerances so close is the loss that takes place Barrier fluid is negligible.
  • the seal is also a with Bulk liquid operated packing seal 12c.
  • the barrier liquid supplied from the outside.
  • the supply channel generally provided exclusively in the seal housing In the example of Fig. 3, the supply via a Bore 18 in the corresponding seal housing 11c.
  • the in the housing cover 5 located hole 15, in the execution as shown in FIG. 2 for the supply of sealing fluid from within The pump is shut off in this case by on the closed circumference of the seal housing 11c opens.
  • matching housing cover 5 used. Only the seals and seal housing are formed differently.
