Description
Technical field
A kind of umbrella-type generator group top guide bearing oil throwing device is the utility model is related to, belongs to umbrella-type hydraulic generator
Unit top guide bearing protection technology field.
Background technology
Umbrella-type generator group top guide bearing in operation due to rotary shaft rotary blasting act on, axle journal inner underside with
Local decompression can be formed between oil blocking barrel, upper oil guide groove oil level, which is inhaled height, to be caused to get rid of oil, or unit bias causes big axle to rotate
When periodic pressure oscillation is formed in oil groove, promote turbine oil outwards to escape.In addition in the case where oil level is higher, oily meeting
Climbed upwards along oil blocking barrel, cross at the top of oil blocking barrel, flowed down along big axle, formed in top guide bearing and get rid of oil.
The oil stream part thrown away, which is fallen in oil-containing groove, to flow away, and rotor top is partly flowed out at oil-containing groove seal, together
When, the oil that top guide bearing is thrown away enters rotor and stator interior from upper shaft toward flowing down, mist of oil can with unit rotation not
Break and circulated in wind turbine apparatus, oil stream can not only influence rotor insulation, and can pollute rectification unit along rotor toward flowing down
Running environment, and a large amount of turbine oils can be caused to lose, it would be highly desirable to handled.As shown in Figure 1.
Mainly use stop method at present（By taking compulsory measure to be isolated to the oil stream of effusion, stopped, prevent by force
The method that oil stream, mist of oil escape）Oil is got rid of in processing guide bearing, typically installs gear oil additional by keeping off cylinder upper end in top guide bearing
Ring.But should in this way handle and oil is got rid of in top guide bearing, good effect may not necessarily be reached.Because although oil scraper ring can be with
The oil stream of the upward play of stop portions, but due to mist of oil and splash oil droplet can bypass oil scraper ring and through oil scraper ring with it is upper
Gap between guide bearing, so getting rid of oil in top guide bearing by installing oil scraper ring additional to handle, its effect has certain limitation.
Utility model content
The technical problems to be solved in the utility model is：A kind of umbrella-type generator group top guide bearing oil throwing dress is provided
Put, have easy for installation, simple to operate, the features such as oil throwing effect is good, the shortcomings of the prior art can be overcome.
The technical solution of the utility model is：A kind of umbrella-type generator group top guide bearing oil throwing device, including it is upper
Oil blocking barrel and upper oil guide groove in guide bearing, oil blocking barrel upper end is provided with when unit operation rotates in top guide bearing, can shape
Into downward air-flow, the flow deflector caused mist of oil in running and the oil droplet of splashing being pressed back into upper oil guide groove.
The flow deflector is uniformly arranged on oil blocking barrel upper end circumferencial direction in top guide bearing.
The radial direction of the flow deflector and top guide bearing has angle of inclination.
The angle of inclination is 120 degree~160 degree.
The beneficial effects of the utility model are：The utility model passes through the oil blocking barrel upper end circumferencial direction in top guide bearing
Design flow deflector, the structure of overall similar fan, so in unit running process, due to blasting action caused by rotation,
In the presence of flow deflector, downward air-flow is formed, caused mist of oil in running and the oil droplet of splashing are pressed back into oil groove,
Oil mass is got rid of in top guide bearing so as to eliminate or greatly reduce.The utility model has easy for installation, simple to operate, oil throwing effect
The features such as fruit is good, suitable for being led in umbrella-type generator group, thrust, under lead, oil processing got rid of in water pilot bearing, for other
The turbine-generator units bearing of type gets rid of oil processing, equally with extraordinary reference.
Brief description of the drawings
Fig. 1 is to get rid of oily schematic diagram in top guide bearing；
Fig. 2 is structural representation of the present utility model；
In figure：1st, oil blocking barrel in top guide bearing, 2, upper oil guide groove, 3, flow deflector.
Embodiment
Below in conjunction with the accompanying drawings and utility model is described further specific embodiment：
With reference to figure 2, a kind of umbrella-type generator group top guide bearing oil throwing device of the utility model, to existing upper leading axle
Hold interior oil blocking barrel to be transformed, the upper end circumferencial direction of oil blocking barrel 1 is evenly arranged with when unit operation rotates in top guide bearing
When, downward air-flow can be formed, caused mist of oil in running and the oil droplet of splashing are pressed back into leading in upper oil guide groove 2
The radial direction of flow 3, flow deflector 3 and top guide bearing has angle of inclination, and angle of inclination, which selects 120 degree~160 degree, to be advisable.
Applicant in actual transformation process, processed surface smoothness be Ra be 6.3, a width of 200mm*20mm of long * iron
Piece, i.e. 16 pieces of flow deflector, it is after unit carries out large repairs and decomposes top guide bearing dismounting, process 16 pieces of flow deflectors 3 are uniform
The upper end of oil blocking barrel 1 in top guide bearing, flow deflector 3 and horizontal +X direction are welded on into 155 ° of angles.After the welding fabrication of flow deflector 3,
Structure of the overall composition similar to fan.Unit in the process of running, due to blasting action caused by rotation, in flow deflector 3
Under effect, downward air-flow is formed, caused mist of oil in running and the oil droplet of splashing are pressed back into oil groove, so as to eliminate
Or greatly reduce the interior of top guide bearing and get rid of oil mass.
Above content is to combine specific preferred embodiment further detailed description of the utility model, it is impossible to
Assert that specific implementation of the present utility model is confined to these explanations.For the ordinary skill of the utility model art
For personnel, without departing from the concept of the premise utility, some simple deduction or replace can also be made, should all be regarded
To belong to the scope of protection of the utility model.
