Description
Technical field
The utility model belongs to turbine equipment technical field, is related to a kind of axis and stretches tubular-Francis turbine runner oil-free tune paddle behaviour
Make mechanism.
Background technology
Existing rotary propeller type axis stretches tubular turbine, and blade operation format mainly has two kinds of piston type and cylinder moving type, this
Two kinds of structures are required for oil head to transfer pressure oil.For oil head because its is complicated, sealing is difficult, oil leak usually occurs, alters
The problem of oily, while traditional axis stretches through-flow Kaplan turbine since structure limits, oil and the bearing lubrication system of governing system
The oil of system mixes, make governing system require high oil often pollution and cause governor card resistance, reduce unit can
By property.And since the pump start in governor oil pressure device is frequent, power consumption is also big while causing oil pump serious wear.
And both structures operationally have pressure oil in hub body, and cylinder moving type structure is low pressure oil, and piston cylinder operator is high pressure
Oil.Pressure oil adds the difficulty of blade sealing, even if employing effective seal form, the service life of blade sealing also can be significantly
Shorten.Blade oil leak after blade seal failure, can pollute river and environment.
Utility model content
In order to overcome the disadvantages mentioned above of the prior art, the utility model provides a kind of axis and stretches tubular-Francis turbine runner oil-free tune paddle
Formula operating mechanism, it realizes oil free type blade operation structure in hub body, has effectively achieved the optimization of structure and performance.
Technical solution is used by the utility model solves its technical problem：A kind of axis stretches tubular-Francis turbine runner oil-free tune
Paddle operating mechanism, including servomotor bar, the high pressure blade electro-hydraulic actuator of one end small shaft end of the connection hydraulic turbine of servomotor bar,
The other end connects the in vivo crosshead of wheel hub, and crosshead is then linked by connecting plate and pivoted arm, and pivoted arm is sleeved on sharf, passes through pin
Torque is transferred, snap ring is stuck in the card slot of sharf and fixes pivoted arm, by the reciprocating motion of servomotor bar, drives crosshead, connects
Plate, pivoted arm operation blade rotate；It is set between crosshead and hub body guide groove there are three feather key, can prevent crosshead from rotating.
The servomotor bar is fixedly linked by nut and crosshead.
The hub body one side is provided with draft cone.
The axle sleeve installed in the hub body is self-lubricating steel back axle sleeve.
It is sealed in the blade outboard equipped with blade.
The servomotor bar is connected by small axis with high pressure blade electro-hydraulic actuator power.
The beneficial effects of the utility model are：The problems such as efficiently solving complicated oil receiver structure, oil leak and altering oil；Tune
The oil of speed system and bearing lubrication system is separated；Blade operation oil pressure is increased to 16.0Mpa；And it is no oil ring in hub body
Border solve thes problems, such as blade oil leak, while has prevented pollution of the oil leak to environment.

6 one side of hub body is provided with draft cone 3.
The axle sleeve of installation is self-lubricating steel back axle sleeve 9 in the hub body 6.
Blade, which is equipped with, in 11 outside of blade seals 12.
The servomotor bar 8 is connected by small axis 7 with high pressure blade electro-hydraulic actuator power.
The problems such as the utility model efficiently solves complicated oil receiver structure, oil leak and alters oil；Governing system and bearing
The oil of lubricating system is separated；Blade operation oil pressure is increased to 16.0Mpa；And be no oil environment in hub body 6, effectively solve
Blade seal 12 oil leaks the problem of, while prevented pollution of the oil leak to environment.
