Definitions
- Centrifugal pump housings generally consist of one or several housing parts that make up the work space or work spaces enclose on the circumference, as well as a lid which the pump shaft is guided sealed into the housing. Because there are different types of seals, different ones Requirements for the shape of the housing cover it is common for anyone related to one Pump type to use a special housing cover to provide. This is expensive because different Lids would have to be kept in stock. They are too Lids, which are often shaped in a special way and are therefore cast or forgings are the more expensive, the more different Forms of it exist.
- the invention has for its object to this effort reduce, and achieves this by the specified in claim 1 Features and preferably by those of the subclaims.
- the housing cover has an assembly opening and predetermined for each seal from a group Seals related to this lid are to be used, an insertable into the assembly opening and with the cover a sealing housing enclosing a static seal is provided. It is therefore not necessary considering different seal types several Keep lid shapes in stock. In contrast to the housing cover the seal housings are inexpensive to manufacture Parts.
- the advantage is thus achieved that the effort for both the production as well as the storage of the lid is reduced becomes. Furthermore, the invention allows for a given Pump the seal against another one afterwards Type including seal housing to be replaced without the Pump cover is replaced. This usually takes not even being solved.
- any of the predetermined seals operate with barrier fluid it can, in particular, if this blocking medium should be removed from the pump, it should be appropriate that the cover and the seal housing with aligned holes be provided for the supply of the barrier medium.
- the hole in In this case, cover can be present regardless of this whether the seal type that requires the locking medium is used will or not.
- the cover hole is aligned the corresponding hole in the seal housing; in the other Case, the cover hole is carried out by the closed Seal housing blocked.
- the supply channel can generally only in the seal housing be provided.
- the aligned holes in the opposite one another Circumferential surfaces of the mounting opening and the seal housing open out these peripheral surfaces being designed as mating surfaces are.
- the execution as mating surfaces means that their dimensions each within a narrow tolerance range are approximated so that one may be between them remaining gap is so small that the Locking medium losses occurring are negligible. It it is understood that in this case the peripheral surfaces mentioned are located within the static seal that the Sealing housing seals against the housing cover, see above that any leakage remains in the pump and not get out.
- the housing of the pump comprises a main housing part 1, the foot 2, the suction port 3 and the pressure port 4 forms, and on the other hand a housing cover 5, which the Main housing part 1 on the drive side closes.
- a bearing housing 6 the two Bearing 7 for the shaft 8, which through the cover 5 in the housing is guided and carries the impeller 9 there.
- the housing cover 5 For the passage of the shaft 8 contains the housing cover 5 one Passage opening 10, which is closed by the seal housing 11 which in turn holds the seal 12.
- the Seal housing 11 is in the area of the end faces 13 screwed the housing cover 15 and by a suitable static seal sealed.
- the seal 12 is as Mechanical seal 12a formed.
- FIG. 2 is a Stuffing box 12b in a chamber of the seal housing 11 is axially compressed by means of glasses 14.
- she is intended for operation with sealing liquid, which is caused by a bore 15 taken from the pump chamber near the pressure side is and via a bore 16 in the seal housing 11, which with the bore 15 is aligned, enters the packing area.
- the Transition from hole 15 to hole 16 takes place in the area of the gap 17 between opposing peripheral surfaces the seal housing 11 and the housing cover 5 instead, which is so narrow by choosing suitable dimensional tolerances, that the loss of barrier liquid that occurs as a result is negligible.
- the seal is also one with Bulk liquid operated packing seal 12c.
- the difference 2 is the barrier liquid supplied from the outside, via a bore 18 in the seal housing 11.
- the hole in the housing cover 15 15, in the embodiment according to FIG. 2 for the supply of Bulking liquid from inside the pump is in it Trapped by clicking on the closed scope of the Seal housing 11 opens.
- housing covers are designed to match 5 used. Only the seals and seal housing are trained differently.
