Abstract
The utility model relates to a metal honeycomb seal which is composed of a sealed body and a honeycomb belt. The honeycomb belt and the sealed body are combined. A magnetic column is also arranged on the sealed body. The sealed belt and the sealed body are assembled into floating equipment. A sealed tooth is also arranged at one side of the assembling of the sealed body and the honeycomb belt. The sealed tooth and the sealed belt are staggered equipped. A cylinder is directly connected with the outer side of the sealed body. An adjusting block is arranged in the cylinder. The main function of the metal honeycomb seal is that it stops inside and outside leakage of the working medium, the lubricating medium or the cooling medium of the fluid machinery high speed rotating shaft system such as the steam turbine, the compressor, the turbine, the blowing machine and the internal combustion engine to enhance the efficiency of the fluid machinery and save energy and protect the environment and realize safe and stable operation.
Description
Technical field
The utility model relates to a kind of metal beehive sealing.
Background technique
The tradition axle that runs up is that the Comb Labyrinth Seals structure is adopted in the sealing of working medium, lubricant medium or cooling medium more, rely on fluid by the labyrinth sealing gap of broach and axle system the effect that the joint inhibition effect reaches sealing to take place successively, but since the defective of Comb Labyrinth Seals self and seal clearance cannot say for sure the property demonstrate,proved, cause a large amount of leakages of medium, and influence the safe operation of fluid machinery.In a word, the major defect of traditional Comb Labyrinth Seals has:
1. sealing effect is not good, and dielectric leakage is serious.
2. the axle shake phenomenon that causes fluid machinery easily produces.
3. the destruction that mill causes axle system is bumped on broach and axle system surface.
4. the pollution and the non-safety operation that leak outside and cause environment of medium.
The model utility content
Shortcoming at above conventional seals technology; the purpose of this utility model is to provide a kind of novel metal honeycomb seal, in order to reduce the leakage of fluid machinery working medium, lubricant medium or cooling medium, raises the efficiency; energy saving, protection environment and safe operation.
In order to guarantee to realize above-mentioned purpose, the utility model by the following technical solutions: a kind of metal beehive sealing, it is made of seal and cellular band, wherein, cellular band and seal combination.
Also be provided with the magnetic post on described seal, sealing strip and seal are combined as the float type setting.
One side of seal and cellular band combination also is provided with the sealing tooth, and sealing tooth and sealing strip stagger arrangement are provided with, and directly connects cylinder body in the seal outside, is provided with the adjustment piece in the cylinder body.
Seal is divided into inside and outside seal, and inside and outside seal connects or welding by bolt.
Cellular band is the ladder-type setting.
Above-mentioned cellular band directly with seal soldering be in the same place.
The cellular band material adopts nickel base superalloy.
The material of sealing tooth is a ferrite.
Above-mentioned seal is formed for the segmental arc of whole circle garden ring or two, polylith.
The sealing of the utility model metal beehive has solved the shortcoming of traditional labyrinth seal technology, has reached the purpose of appeal creation request.
The utlity model has following advantage:
1. effectively improve the efficient of fluid machinery.
2. effectively prevent the leakage of medium, reach good sealing effect.
3. the not injury injury of axle system of convection cell machinery.
Energy saving, protection environment, security of operation.
