Abstract
The utility model relates to a gas-seal anti-oil mist overflowing structure of a hydraulic generator. A gas source port of a rotator fan high-pressure region is communicated with a total air inlet pipe through an interface flange; the outlet of the total air inlet pipe is divided into two ways, wherein one way enters an oil tank from the upper-layer cavity of an upper sealing cover of a labyrinth oil-tank cover through the pipeline and is exhausted from the lower cavity of the upper sealing cover, and the other way enters the oil tank from the lower cavity of a lower sealing cover of the labyrinth oil-tank cover through the pipeline and is exhausted from the upper cavity of the lower sealing cover. The benefits of the gas-seal anti-oil mist overflowing structure of the hydraulic generator are as follows: through leading the pressure gas source to the upper/lower sealing covers from the inner part of generator and balancing the internal/external pressure of the oil tank of a thrust bearing and recycling the oil mist, the running quality of the unit is greatly increased, the maintenance workload of the unit is reduced, and the safe, stable running of the unit is ensured; the structure has characteristics of reasonable structure, low cost, non-maintaining, convenient operation and improved work efficiency.
Description
[technical field]
The utility model belongs to the hydraulic turbine generator equipment technical field, relates to a kind of sealing gland pipeline and upper-lower seal lid of adopting and overflows structure for the anti-mist of oil of the hydraulic turbine generator sealing gland of double-layer seal.
[background technique]
The inner phenomenon of getting rid of oil, oil groove mist of oil that takes place of existing hydraulic generator set thrust bearing, existence is in various degree all arranged in a lot of high rotating speed units, in unit operation, thrust collar and runner plate outer wall can drive is stained with stagnant quiet oil motion, make pasta gush height, splash or stir to the oil groove outer wall because of action of centrifugal force, form mist of oil, and overflow, form the outer oil that gets rid of from oil groove cover plate slit.Therefore, along with the operation of unit, bearing temperature raises, and oil and volume of air in the oil groove is expanded, thereby produced interior pressure, and under the effect of interior pressure, the mist of oil in the oil groove can overflow from the cover plate slit with gas.The oil seal imprecision of thrust-bearing not only will consume lubricant oil more, and will pollute winding, damages insulation, influence unit safety operation, and at above-mentioned shortcoming, existing adopt installed contact seal oil catch structures more, but its cost height, needs maintenance.
[model utility content]
In order to overcome the above-mentioned shortcoming of prior art, the utility model provide a kind of simple and reasonable, cost is low, the anti-mist of oil of hydraulic turbine generator sealing gland of non-maintaining, easy-to-operat and raising work efficiency overflows structure.
The technological scheme that its technical problem that solves the utility model adopts is: the anti-mist of oil of a kind of hydraulic turbine generator sealing gland overflows structure, rotor fan zone of high pressure source of the gas mouth links by flange and total inlet pipe, the total inlet pipe outlet divides two the tunnel, and the top cover labyrinth upper chamber that the pipeline of wherein leading up to covers from the mazy type oil groove enters to the top cover labyrinth cavity of resorption and only discharges; The lower sealing cover cavity of resorption that another road is covered from the mazy type oil groove by pipeline enters to the lower sealing cover epicoele and only discharges.
The anti-mist of oil of described hydraulic turbine generator sealing gland overflows structure and is provided with oil trap, is provided with gas exhaust piping in the upper leading axle bearing of oil trap.
Uniform porose on described upper leading axle bearing wall.
The beneficial effects of the utility model are: by in motor internal pressure strength source, guide to the upper-lower seal lid, the external and internal pressure in the balance thrust-bearing oil groove, mist of oil is reclaimed, significantly improve the unit operation quality, reduced the maintenance workload of unit, guaranteed unit safety stable operation; Have simple and reasonable, cost is low, the characteristics of non-maintaining, easy-to-operat and raising work efficiency.
[description of drawings]
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1-flange, 2-total inlet pipe, 3-suction tude, 4-lower sealing cover, 5-top cover labyrinth, 6-outlet pipe, 7-oil tank vent, 8-rotor fan zone of high pressure, 9-upper leading axle bearing, 10-top guide bearing chamber, 11-mazy type oil groove lid, 12-oil trap, 13-hole.
[embodiment]
Below in conjunction with drawings and Examples the utility model is further specified.
Referring to Fig. 1, the anti-mist of oil of a kind of hydraulic turbine generator sealing gland overflows structure, the source of the gas mouth of rotor fan zone of high pressure 8 links by flange 1 and total inlet pipe 2, total inlet pipe 2 outlet divides two the tunnel, and the pipeline of wherein leading up to enters from top cover labyrinth 5 upper chambers of mazy type oil groove lid 11, forms certain static pressure in groove, thereby stop oil gas mixture outwards to be revealed, play the effect in balance top guide bearing chamber 10, discharge from top cover labyrinth 5 cavity of resorptions again, be connected to outside the factory building; Another road enters by lower sealing cover 4 cavity of resorptions of pipeline from mazy type oil groove lid 11, discharges from lower sealing cover 4 epicoeles.Simultaneously, the anti-mist of oil of described hydraulic turbine generator sealing gland overflows structure and is provided with oil trap 12, is provided with gas exhaust piping in the upper leading axle bearing 9 of oil trap 12, the mist of oil in the oil groove directly can be discharged outside the factory building.In addition, be negative pressuren zone at thrust collar and oil groove cover plate for sealing place, can increase the weight of oil atomization and mist of oil escapes, therefore in the hole 13 of the uniform brill of upper leading axle bearing 9 walls 8-Φ 8, in order to the air pressure in balance upper leading axle bearing chamber and the oil-collecting vallecular cavity.
