Abstract
The utility model relates to a sealing device of a steam turbine, which belongs to the field of the steam turbine accessories. The sealing device comprises a front sealing block, a back sealing block, seal teeth and sealing rings, wherein, the front and the back sealing blocks are arranged on a rotor, and the seal teeth and the sealing rings are processed on each sealing block and the rotor. The key point of the utility model is that at least three groups of seal teeth and sealing rings are processed on each sealing block and each rotor. After the prior art is improved, the original sealing structure of the sealing blocks and the rotor is improved. Therefore, the utility model has the advantages that the phenomenon of steam leakage in the steam turbine is solved, the sealing performance is good, and the regular production in enterprises can be ensured.
Description
Technical field
The utility model belongs to the steam turbine field of accessories, specifically is a kind of steam turbine seal arrangement.
Background technique
Steam turbine is one of Chemical Manufacture enterprise equipment commonly used; present steam turbine is in actual application; principal fault usually takes place; cause using the frequent shutdown of enterprise to be overhauled; waste time and energy; not only increase the user cost of equipment, reduced manufacturing efficiency, but also had a strong impact on the ordinary production operation of enterprise.
The model utility content
The purpose of this utility model is to solve above-mentioned deficiency of the prior art, and prior art is improved, and a kind of solution steam turbine gas leak phenomenon is provided, good seal performance, the steam turbine seal arrangement of guarantee enterprise ordinary production.
For achieving the above object, the utility model is achieved through the following technical solutions:
Be a kind of steam turbine seal arrangement, comprise being arranged on epitrochanterian forward and backward sealing block, and sealing tooth, the seal ring processed on each sealing block and the rotor that the present technique main points are sealing tooth, seal ring at least three groups of processing on each sealing block and the rotor.
In order to improve the sealability of steam turbine, the sealing tooth of processing on each sealing block and the rotor, seal ring are 3～9 groups, and its best preferred version is that sealing tooth, the seal ring processed on each sealing block and the rotor are 4～6 groups.
After the utility model improves prior art,, therefore has the steam turbine of solution gas leak phenomenon, good seal performance, the advantage of guarantee enterprise ordinary production owing to improved the sealing configuration of original sealing block and rotor.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1: the utility model example structure schematic representation.
Embodiment
As shown in Figure 1, this steam turbine seal arrangement, comprise being arranged on epitrochanterian forward and backward sealing block 1,5, and the seal ring 2 of processing on each sealing block 1,5 and the rotor 4, sealing tooth 3, the present technique main points are on each sealing block 1,5 and the rotor 4 seal ring 2, sealing tooth 3 at least three groups of processing.
In order to improve the sealability of steam turbine, the seal ring 2 of processing, sealing tooth 3 are 3～9 groups on each sealing block 1,5 and the rotor 4, and its best preferred version is that seal ring 2, the sealing tooth 3 of processing on each sealing block 1,5 and the rotor 4 is 4～6 groups.
After the utility model improves prior art, owing to improved the hermetically-sealed construction of original sealing block and rotor, so tool The steam turbine of solution gas leak phenomenon is arranged, good seal performance, the advantage of guarantee enterprise ordinary production.
