The utility model relates to a simple structure, low in manufacturing cost, sealed effectual axle head sealing device for high-pressure nitrogen gas blower.
Description
Technical Field
The utility model relates to a fan gas delivery seals technical field.
Background
With the rapid development of national economy, the requirement of an air blower for conveying special media is greater, and the sealing effect is poor due to the adoption of conventional common sealing; the dry gas seal or the mechanical seal is adopted, the cost is too high, and the installation, the maintenance and the overhaul are extremely complex.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the technical problem and providing a simple structure, low in manufacturing cost, sealed effectual axle head sealing device for high-pressure nitrogen gas blower.
In order to achieve the above object, the utility model adopts the following technical scheme: a shaft end sealing device for a high-pressure nitrogen blower mainly comprises a graphite sealing group (4), a shaft end sealing flange (5), a shaft end high-low tooth seal (6), a machine shell (7) and a main shaft (8), and is characterized in that the shaft end high-low tooth seal (6) is arranged on the machine shell (7) through a positioning sub-opening, the main shaft (8) and the shaft end high-low tooth seal (6) are arranged on the machine shell (7) according to a corresponding groove and a corresponding sealing tooth, the shaft end sealing flange (5) and the graphite sealing group (4) are both of a middle split structure, the shaft end sealing flange (5) is locked on the machine shell (7) through a high-strength bolt (2), the graphite sealing group (4) is sleeved on the main shaft (8) and is adjusted and locked on the shaft end sealing flange (5) through an inner hexagonal bolt (3), nitrogen filling holes (9) are arranged on the shaft end high-low tooth seal (6) and the machine shell (7), the nitrogen charging pipe group (1) is communicated with a nitrogen charging hole (9), so that high-pressure sealing nitrogen enters a sealing cavity of a shaft end high-low tooth seal (6) and a main shaft (8).
By adopting the technical scheme, the shaft end sealing device for the high-pressure nitrogen blower is convenient to install, short in processing and manufacturing period and low in manufacturing cost, and is particularly suitable for sealing shaft ends of high-pressure nitrogen or other high-pressure gases.
Drawings
FIG. 1 is a schematic view of a shaft end sealing device for a high pressure nitrogen blower according to the present invention;
in the figure: 1. a nitrogen charging pipe group; 2. a high strength bolt; 3. a hexagon socket head cap screw; 4. a graphite seal group; 5. a shaft end sealing flange; 6. the high and low teeth of the shaft end are sealed; 7. a housing; 8. a main shaft; 9. and (4) filling nitrogen holes.
