Definitions
- the invention relates to an element to be arranged on the shaft of a turbomachine, defining a gap for the limited passage of a flow medium, with a socket-like part to be arranged on the shaft of the turbomachine, which has a recess for a ring on its outer circumference, the one on its end faces ring partially enclosed by annular walls of the recess during the operation of the turbomachine a) forms an axial gap with the annular walls of the recess and forms a radial gap with the base of the recess, b) is held by a rigid wall surrounding the ring by friction.
- a recess is formed in the rigid wall surrounding the ring, which encloses the free end faces of the ring from the walls of the bush-like part, one of the lateral boundaries of the recess being releasably connected to the rigid wall tubular part is formed.
- the ring is enclosed on all sides, so that there is no gap into which the ring could escape.
- a limiting ring which is detachably connected to this part is arranged in the wall of the recess of the piston or the bushing opposite the tubular part.
- an elastic ring that is separated by a longitudinal gap can also be installed in this way. However, this can also be widened and pushed over one of the side walls of the bush-like part, with less effort for the bush-like part on the shaft side.
- a particular advantage of the invention is that the entire element, including the surrounding wall, which in this case is also formed by a bushing, can be combined from separately manufactured parts outside the turbomachine to form a cartridge which is ready for assembly.
- the invention can be used with advantage above all for an axial thrust compensation device or a shaft seal.
- FIG. 1 is a sectional view of a cartridge designed to be assembled
- Fig. 2 is a sectional view of a largely corresponding to Fig. 1 cartridge with a closed ring.
- FIGS. 1 and 2 serve as relief pistons in axial thrust compensation devices. Both versions have in common a - in a - not shown - centrifugal pump housing rotatably and immovably to be arranged socket 1. The remaining parts of the elements are inserted into socket 1, respectively. On the - not shown - shaft of the centrifugal pump, another bush-like element, a piston 2 or 3 is to be arranged.
- the piston 2 in the embodiment of FIG. 1 has a recess 4 into which a piston ring 5 is inserted.
- the piston ring 5 is made of elastic material and is separated by an axially extending slot (not shown). The elasticity and the separation make it possible to push the piston ring 5 over the side wall 6 of the piston and to snap it into the recess 4.
- a tubular retaining ring 7 is provided on the side of the cartridge opposite the side wall 6, which is inserted into the bushing 1 after the piston 2 and the piston ring 5 have been inserted and is fastened to the bushing 1 by screws 8.
- the retaining ring 7 has two effects: First, it holds the cartridge together. Secondly, it prevents the piston ring 5 from expanding into the area between the piston 1 and the bush 2, as a result of which gradual wear in the area of a gap which is present in the previously known embodiment is avoided.
- the piston 3 in the embodiment of FIG. 2 has a shoulder 9, on which a closed piston ring 10 is pushed.
- a limiting ring 12 fastened to the piston 3 by means of screws 11 is attached to the open side of the piston 3, ie opposite the retaining ring 7.
- the retaining ring 7 and the screws 8 correspond to the embodiment in FIG. 1.
- a modification results if, instead of a ready-to-install cartridge, a bushing is used which is fastened in the housing of the turbomachine and which is only connected in the housing to the other parts of the element.
- the invention is nevertheless also used in such an embodiment, which appears to be less advantageous.
