Pressure oil is transported to by the oil head (pressure oil converter) of chain-drive section by oil pipe is mounted on the intracorporal servomotor of runner, relay
Device passes through web operating mechanism again and adjusts blade angle.Servomotor the problem of there is oil leaks, but because in web and
It is each filled with the oil for playing lubrication and driving in the big axis of unit, so servomotor is in oil-overflow web, servomotor oil leak
Hydraulic turbine work is not influenced.
But operation and oil-overflow feathering vane runner in water in actual operation, are impregnated, oil leak is more or less had.
Oil leak can be discharged to downstream with tail water, have very big pollution to destroy the DRINKING WATER in downstream, irrigation and ecology.With China's ring
The reinforcement of border protective awareness, because the regulation of environmental pollution caused by the oil leak of power station turbine-generator units is also being reinforced.
This just forces many power stations to carry out technical renewal transformation to Kaplan turbine, and oil-free Kaplan turbine has very big application
Prospect.
205330865 U of Chinese patent application publication number CN, application date of declaration are 2016.06.22, entitled " a kind of
Oil-free lubrication Kaplan turbine runner " discloses a kind of oil-free lubrication Kaplan turbine runner.This utility model is related to
To being injected into rotary wheel of water turbine body water or with environmental-friendly liquid, instead of before full of inside web
Oil solves the problems, such as oil leak.But be not easily found with environmental-friendly liquid, it only makes and lubricates of water, effect is done not as good as oil
Lubricant, and to the heavy workload of web injection liquid, it is inconvenient for operation.The program is also without solving servomotor leakage simultaneously
The problem of oil.

Disk, cyclic annular splash pan can be lifted down from bracket, then recycle oil.
Scheme as a preference of the above scheme, the vane regulator operating mechanism is all using inserted from profit
Sliding composite bearing.Because vane regulator operating mechanism is located in rotary wheel of water turbine body.Web always works under water, no
Facilitate maintenance.It is because the composite material that this bearing uses is one that this operating mechanism, which selects mosaic self-lubricating composite bearing,
The anti-extreme pressure solid lubricant of kind, than general steel back axle sleeve, the service life is longer, and anti-pressure ability is stronger.
The beneficial effects of the utility model are:
Since rotating vane servomotor is moved the motor head for being equipped with turbine oil receptor, oil head can will be pressed
Power oil quickly passes to rotating vane servomotor, and the oil leaked at servomotor will not directly enter water, facilitate recycling；
Due to being oil-free environment in rotary wheel of water turbine body, impregnating the hydraulic turbine run in water can just be leaked into without oil
In water, environmental pollution is avoided；
Due to there is a series of devices for collecting oil leak such as draw-off tray at rotating vane servomotor, it can prevent servomotor from leaking
Oil enter in rotary wheel of water turbine body, and leak oil can also recycling and reusing, energy conservation but it is environmentally friendly；
Since the intracorporal operating mechanism of runner has used mosaic self-lubricating composite bearing, the service life is longer long, reduces
Maintenance cost.
