Abstract
The utility model relates to a compressed air sealing device for an oil seal, which is applied to a steam turbine for an electric power plant for protecting the oil seals on a front bearing seat and a rear bearing seat of the steam turbine. The compressed air sealing device for the oil seal is characterized in that an air compressor, a main pipe, a front blowing pipe, a rear blowing pipe, a front valve and a rear valve are included, wherein the air compressor is connected with the main pipe, the front blowing pipe and the rear blowing pipe are arranged on the main pipe, the front valve and the rear valve are arranged on the front blowing pipe and the rear blowing pipe respectively, an opening of the front blowing pipe is positioned between the rear bearing seat and the steam turbine, and an opening of the rear blowing pipe is positioned between the front bearing seat and the steam turbine. The compressed air sealing device has the advantages of reasonable structural design, simplicity, reliability and can be used for protecting the oil seals well.
Description
Technical field
The utility model relates to a kind of oil sealing compressed air sealing device, is applied in the power plant steam turbine device oil sealing on the antero posterior axis bearing of protection steam turbine.
Background technique
Existing steam turbine is in operation because of the packing wearing and tearing, and the gap increases, and causes that this position steam leaks outside, and directly scurries in the adjacent bearing support.Cause oil mixed with water, it is normally lubricated to influence bearing, brings potential safety hazard to unit.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of reasonable in design, simple and reliable, the oil sealing compressed air sealing device that can well protect oil sealing.
It is this oil sealing compressed air sealing device that the utility model solves the problems of the technologies described above the technological scheme that is adopted, be characterized in: form by air compressor, house steward, preceding blowpipe, back blowpipe, early gate, late gate, described air compressor links to each other with house steward, blowpipe and back blowpipe before house steward is provided with, be respectively arranged with early gate, late gate on preceding blowpipe, the back blowpipe, the fore blow tube opening is between rear bearing block and steam turbine, and the after-blow tube opening is between front-end bearing pedestal and steam turbine.
House steward described in the utility model is provided with house steward's valve.
The utility model is compared with prior art and is had the following advantages and effect: by installing compressed air plant of the present utility model additional, winding-up intercepts the turbine steam seal steam that leaks outside and scurries in the bearing support, the oil mixed with water problem is effectively controlled, and safety in operation is protected.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with embodiment the utility model is described in further detail, following examples are to explanation of the present utility model and the utility model is not limited to following examples.
Embodiment 1: as shown in Figure 1, present embodiment is made up of air compressor 1, house steward 2, preceding blowpipe 3, back blowpipe 4, early gate 5, late gate 6, house steward's valve 11, described air compressor 1 links to each other with preceding blowpipe 3, back blowpipe 4 by house steward 2, the opening end of preceding blowpipe 3 is arranged between steam turbine 9 and the front-end bearing pedestal 8, and the opening end of back blowpipe 4 is arranged between rear bearing block 10 and the steam turbine 9.House steward 2 is provided with house steward's valve 11, is respectively arranged with early gate 5, late gate 6 on preceding blowpipe 3, back blowpipe 4.
During work, start air compressor 1, control pressurized air and protect oil sealing by control early gate 5, late gate 6, house steward's valve 11.
In addition, need to prove, the specific embodiment described in this specification, its zero, the shape of parts, institute's title of being named etc. can be different.Allly conceive equivalence or the simple change that described structure, feature and principle are done, be included in the protection domain of the utility model patent according to the utility model patent.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment; only otherwise depart from structure of the present utility model or surmount the defined scope of these claims, all should belong to protection domain of the present utility model.
