Technical field
This utility model relates to a kind of turbine parts, particularly relates to a kind of oil-free lubrication Kaplan turbine runner。
Background technology
Being fill with oil completely inside traditional feathering vane runner, the oil within runner ensures there is certain pressure。Filling oil in runner, is mainly lubricated the bearing of the parts such as blade pivot and linkage, it is prevented that water enters runner, can obtain the antirust effect with lubrication and seal part of metal parts simultaneously。Although runner is very low to the probability of runner leakage of oil, but As time goes on, component wear, sealing member are aging, burst accident, all can increase the risk of leakage of oil。When some parts generation problem of runner, such as blade seal failure, draft cone bolt fracture, substantial amounts of oil can be caused to leak in river, cause environmental pollution and cause social problem。If additionally, runner is internal immerses river water, by reducing the lubricating function of oil, causing the damage of runner parts。
Utility model content
This utility model is in order to solve defect and the deficiency existed in above-mentioned prior art, it is provided that a kind of without oil lubrication, reduces the runner risk to river leakage of oil, and the feature of environmental protection is good, the oil-free lubrication Kaplan turbine runner that but operating cost is low。
The technical solution of the utility model: a kind of oil-free lubrication Kaplan turbine runner, including hub body, blade, blade linkage, described hub body side is provided with water injection hole and enters wheel hub for filling clear water or other eco-friendly liquid before unit operation, draining when being provided with osculum for overhauling bottom hub body, described blade servomotor includes cylinder body, cylinder cap, chamber and piston rod, described cylinder body or piston rod are connected with blade by blade linkage, blade exterior and interior axle sleeves it is provided with between described blade and hub body, described blade exterior and interior axle sleeves, axle sleeve on blade servomotor and blade linkage is self-lubricating bearing。
Blade servomotor is to adopt hydraulic oil operate and be arranged in hub body center and be positioned at clear water or other eco-friendly liquid of hub body。
What be filled with in runner boss body is water, or other liquid environment amenable, or is air。
Other liquid environment amenable in this utility model can be: the mixture of water and Environment-friendlyantirust antirust agent。
Preferably, the axle sleeve between described cylinder body and piston rod arranges multiple tracks movable sealing, and multiple-sealed centre is provided with oil leaking hole。
When this kind of structure makes it run, when the movable sealing fault near cylinder body one end, sealing away from cylinder body is prevented from oil entrance wheel hub, and now leakage of oil can drain into the special leak oil tank being positioned at Power Plant by this oil leaking hole, leak oil tank arranges liquid level alarm device in order to detect leakage of oil。
Preferably, described blade servomotor is operated via operating oil line by the pressure oil from speed regulator, described cylinder cap or piston rod are provided with blade feedback rod to provide blade position data to middle control, and therefore this oil-free lubrication runner can with power station classical control system seamless connection。The side of described hub body is additionally provided with passage to monitor water quality in wheel hub。
Preferably, described blade is fixed in radial direction by paddle flange dish and hub body, and described paddle flange dish is provided with other contact site in movable sealing, runner and river and all adopts static seal。
The above seal approach can prevent wheel hub water from oozing out and polluted river on the one hand, river water also can be stoped on the other hand to enter wheel hub, damage runner parts。Movable sealing is V-seal or the sealing of other shapes。
Preferably, described hub body side is provided with draft cone, and described water injection hole is arranged on draft cone。
This utility model adopts the cylinder body (or piston rod) in blade servomotor to promote blade linkage, and blade linkage promotes blade action；Utilize pressure oil operation blade, it is not necessary to oil lubrication internal motion mechanism。
This utility model hub body sets filling opening, discharge outlet to fill clear water entrance wheel hub, draining during maintenance before unit operation。Also set up operation passage to monitor water quality in wheel hub, it is possible to monitor, by analyzing the oil content of water, the working condition that piston cylinder seals。
This utility model adopts water or other eco-friendly liquid to substitute the lubricating oil in conventional runner boss body, adopt the self-lubricating bearing bearing as runner kinematic pair and friction pair of a kind of applicable runner running environment, so that runner will not polluted river run smooth and easy, adopt leak-proof measure to reduce the runner risk to river leakage of oil simultaneously, can be widely used on axial-flow type and tubular Kaplan turbine。
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
1. hub body in figure, 2. blade, 3. blade exterior and interior axle sleeves, 4. draft cone, 5. blade servomotor, 6. piston rod, 7. blade feedback rod, 8. operating oil line, 9. blade linkage, 10. water injection hole, 11. osculums, 12. oil leaking holes, 13. passages。
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is made it is further believed that explanation, but be not the restriction to this utility model protection domain。
As it is shown in figure 1, this oil-free lubrication Kaplan turbine runner。Blade 2 is operated by blade servomotor 5 and blade linkage 9。AB two chamber in blade servomotor cylinder is operated by oil pipe 8 and power station speed regulator UNICOM, is directly joined offer hydraulic oil by speed regulator master。A certain amount of clear water is injected by the water injection hole 10 on draft cone 4 in C chamber in hub body 1 before unit starts first, and during unit maintenance, the osculum 11 that can pass through to be arranged on hub body 1 is discharged。Being additionally provided with the passage 13 of ventilation when running for runner on hub body 1, this passage 13 is by the corresponding aperture on main shaft and atmosphere。
Based on above structure, C intracavity is water and air。Being likely to contact cavity with river is C chamber。By being arranged on the movable sealing (such as V-type) on paddle flange dish and the static seal on draft cone 4, can prevent wheel hub water from oozing out on the one hand and polluted river, river water also can be stoped on the other hand to enter wheel hub。Because C intracavity hydraulic pressure is less than river hydraulic pressure, the probability that wheel hub water leaks into river is extremely low, and the requirement more conventional oil runner of the movable sealing on therefore paddle flange dish is low, and therefore this sealing can simplify design, saves runner cost of manufacture。
A, B two intracavity be oil, on 2 axle sleeves of blade servomotor 5, both sides respectively arrange some movable sealings (as O type seals), are used for isolating A, B chamber and C chamber。Two seal middle part and arrange again oil leaking hole 12, via piston rod 6, hub body 1 and main shaft, collect to the leak oil tank of Power Plant。This structure can monitor seal operation state, once there be leakage of oil to enter leak oil tank, being arranged at the monitoring element on leak oil tank and an alarm signal is controlled to power station, effectively preventing leakage of oil。
Axle sleeve on blade exterior and interior axle sleeves 2, blade servomotor 5 and blade linkage 9 adopts the self-lubricating bearing being suitable for runner running environment, it is ensured that each auxiliary connection is keep low-friction coefficient in the environment of oil-free。Meanwhile, contact surface with water in runner and take antirust treatment。
The beneficial effects of the utility model are, turn the available conventional governing system of oar blade type runner and are operated, but without oil lubrication in wheel hub, and possess multiple measure and prevent operation hydraulic oil pollution river。
