Description
Technical field
The utility model belongs to the hydroelectric facility technical field, is specifically related to circulation self oiling bearing in a kind of slow-speed of revolution.
Background technique
Bearing is one of vitals of hydraulic generator unit, directly influences the operation stability and the unit durability of unit.Divide circulation self oiling bearing and outer circulation bearing in being divided into by the oily circulation type of cooling.Interior circulation self oiling bearing is simple in structure, can save the complicated fuel feeding of a cover, and oil collecting system, Automation Elements also greatly reduce, thereby improve the reliability of unit operation.It is low that interior circulation self oiling bearing has a cost, the advantage that performance is good, but design difficulty is bigger, especially be lower than under the rotating speed of 250r/min, a lot of producers do not have mature technology, dare not design application, at present, the power station of high head is developed often in domestic, and the special low-head development below the 4m is less, and development potentiality is also arranged very much, these special low water head generating unit speeds are generally all lower, therefore, the experimental study to slow-speed of revolution self oiling bearing is significant
The model utility content
Be to solve the above-mentioned defective that prior art exists, the purpose of this utility model is to provide a kind of compact structure, and cost is low, the slow-speed of revolution, and reliable performance adapts to circulation self oiling bearing in the slow-speed of revolution of special low water head generating unit speed requirement.
For achieving the above object, the technical solution adopted in the utility model is: the circulation self oiling bearing has bearing housing in this slow-speed of revolution, be provided with the thrust bearing shoe valve of assembling and radially watt of matching with axle in the housing, has the lubrication oil circulation oil pocket in the housing, it is characterized in that: the fitting surface side of described thrust bearing shoe valve is provided with disc, have wiper groove on the disc, the downside of disc is provided with fuel sucking pipe, the outside of disc has oil box, the oil box side is provided with oil-deflecting cover, and oil-deflecting cover is provided with the oil scraping plate of control flow rate.
Be provided with the pipeline oil pump in the oil pocket of bearing housing bottom.
Adopt the beneficial effect of technique scheme to be: the circulation self oiling bearing is provided with disc in the fitting surface side of thrust bearing shoe valve in this slow-speed of revolution, and the downside of disc is provided with fuel sucking pipe, and the outside of disc has oil box, and the oil box side is provided with oil-deflecting cover.As interior circuit power, have wiper groove by the rotation of disc (thrust disc) on the disc, oil-deflecting cover is provided with the oil scraping plate of control flow rate, to avoid increasing the energy of flow loss owing to oil mass is excessive, causes the situation of oily temperature rise.Unit starting and when shutdown rotating speed less than the 80r/min scope in, exist the situation of not having oil and fuel delivery deficiency, owing to be provided with the pipeline oil pump in this self oiling bearing, when starting and shut down, adopt the pipeline oil pump to carry out the enforced lubricating of a few minutes, avoid influencing the bearing shell life-span or can cause the tile kilning accident owing under inadequate lubrication state, work, and the pipeline oil pump structure is simple, and is cheap, reliable.Compact overall structure, cost is low, the slow-speed of revolution, reliable performance adapts to the requirement of special low water head generating unit speed, and has simplified the factory building layout, brings great convenience for the operation management of unit.
Detect the runnability of circulation self oiling bearing in the slow-speed of revolution below by test: provide rotating power by boring machine during test, under different rotating speeds, test, with private volumn socket joint oil, manual time-keeping.Following test data records under the oil scraping plate full-gear.
Test data
The disc diameter is 660mm, and the wiper groove width is 84mm, and the degree of depth is 22mm, and oil suction highly is 255mm, and the graduated cylinder cross section is 0.0529mm
2. other parameters such as subordinate list are listed.
The subordinate list test parameters
| Rotating speed r/min | Connect oily second time | The gauging degree of depth/mm | Oil mass/L | Flow L/min |
| 60 | 600 | 87 | 4.60 | 0.46 |
| 75 | 171 | 330 | 17.46 | 6.13 |
| 96 | 90 | 330 | 17.46 | 11.64 |
| 128 | 56 | 330 | 17.46 | 18.71 |
| 160 | 54 | 330 | 17.46 | 19.40 |
| 205 | 46 | 330 | 17.46 | 22.77 |
| 250 | 46 | 330 | 17.46 | 22.77 |
Analyze and conclusion
By test data as can be seen, after rotating speed reached 96r/min, the oil mass increase slowed down, when rotating speed during greater than 205r/min oil mass basicly stable.Therefore, can design routinely, and be provided with the design bearing of pipeline oil pump, and conscientiously check fuel delivery less than the unit employing of 200r/min for the unit bearing of rotating speed greater than 200r/min.Should consider then that less than the bearing of 96r/min additionaling power circulates for rotating speed.At this moment, disc border line speed is Vcp, when n=96r/min, Vcp=0.66 π * 96/60 ≈ 3.36m/s. therefore, Vcp=3.36m/s can be used as the minimum parameter of self oiling bearing design.This self oiling bearing minimum speed can reach 100r/min, for the Application and Development of low water head tubular turbine has been created good condition.
