Description
Technical field
This utility model provides a kind of for the sealing device in rotating shaft or gear-box, belongs to technical field of sealing technology.
Background technology
Labyrinth seal is to set several belt sealing teeth being arranged in order rotating around axle, is formed and a series of dam gap and expand cavity between tooth and tooth, sealed medium when passing through the gap in tortuous labyrinth generation throttle effect and reach the device of the purpose of Drain Resistance.Owing to there is gap between the rotor of labyrinth seal and casing, without solid contact, and allowed thermal expansion, and therefore adapting to the occasion of high temperature, high pressure, high speed-frequency, this seal form is widely used in the sealing of steam turbine, gas turbine, compressor, the axle head of aerator and each inter-stage.
In the occasion that some instructions for uses are stricter, sealing device not only to reach the zero leakage of lubricating oil in annular seal space in use, but also to reach to prevent the pollutant in the external world from entering the purpose within annular seal space, in addition, also there is higher requirement in service life for sealing member, therefore it provides a kind of sealing property is very excellent, and the sealing device of long perfomance life, becomes this area problem demanding prompt solution.
Summary of the invention
This utility model provides a kind of Labyrinth seal device, and this is independently arranged fat seal separating device and solves deficiency of the prior art, and it can independently arrange fat, long service life.
Realizing the technical scheme that this utility model above-mentioned purpose adopts is:
A kind of Labyrinth seal device, at least include rotating ring and stationary ring, described stationary ring is fixed on equipment end lid, described rotating ring is fixed on rotation axle and rotates with rotating axle, described rotating ring includes main ring A and seals ring gear A, main ring A overlaps on the rotating shaft vertically, seals ring gear A and is arranged radially on the periphery of main ring A, and sealing ring gear A is provided with more than three；Described stationary ring includes main ring B and seals ring gear B, main ring B is enclosed within rotating ring vertically, seal ring gear B and be installed on the inner headed face of main ring B, seal ring gear B and be provided with two or more, sealing ring gear A intermeshes to intert with sealing ring gear B and is collectively forming tortuous oil storage tank, and arbitrary sealing ring gear B is between two adjacent sealing ring gear A；The bottom sealing ring gear B of annular seal space is provided with backflow hole slot, and the oils and fats in oil storage tank returns annular seal space from return port concentrated flow.
Being provided with annular recess on the periphery of described main ring B, be provided with O-ring seals in groove, described O-ring seals contacts with equipment end cap.
Being provided with positioning step on the periphery of described main ring B, positioning step is positioned at two ends, left and right or the middle part of main ring B, and stationary ring is connected to a fixed by positioning step and equipment end cap.
The Labyrinth seal device that this utility model provides is in use, lubricant grease in annular seal space is by entering oil storage tank between rotating ring and stationary ring, sealing ring gear A set in oil storage tank and sealing ring gear B can stop oils and fats to leak from oil storage tank, also is able to stop extraneous dirt to be entered annular seal space by oil storage tank simultaneously.Additionally, be provided with backflow hole slot near the bottom sealing ring gear B of annular seal space, the oils and fats in oil storage tank returns annular seal space from return port concentrated flow.
