Specific embodiment
The gas turbine Pneumatic drive system involved by utility model is described in detail referring to the drawings.
As illustrated in fig. 1 and 2, the air source flange 1 that air source is connected on pipeline and bracket assembly provides work for whole system
Medium.Flexible conduit 4 is selectively connected between pressure-regulating valve 2 and lubricator package 6 on pipeline and bracket assembly
With elbow 5.The end of pipeline and bracket assembly is connected to air motor 8, the tooth of the output axis connection gas turbine of air motor 8
Roller box 10.
For the ease of installing and reducing influence of the steam turbine vibrations to compressed air source unit, can be set in pipeline and bracket assembly
Put one section of flexible conduit 4.
In order to accurately adjust outlet pressure, in pipeline and bracket assembly end setting pressure interface tube 7, pass through pressure balance
Pipeline is connected to inside pressure-regulating valve 2, to carry out comparison adjusting.
The utility model uses the air motor 8 of small volume as executive component, has light-weight, small, Neng Gouan
The advantages that mounted in narrow position, the space of spindle nose has been greatly saved it.As shown in figure 3, air motor 8 includes rotor 83, blade
82 and 81 three parts of stator.81 both ends of stator are closed by support plate, and rotor 83 is mounted on two ball bearings eccentric in stator 81
On and 81 gap of stator cooperation.Blade 82 moves freely in the radial direction slot of rotor 83, by air pressure and itself centrifugal force
To keep blade against stator 81 to ensure sealing and volumetric efficiency, the o-ring between case lid and bearing cap provides air sealing.
To reduce mechanical complexity, without especially lubricating between the blade 82 and stator 81 inside gas turbine air motor 8
Mode.Since 82 disassembling, assembling and replacing of blade is convenient, therefore by 82 material of blade less than 81 hardness of stator in the range of, improving stator 81 makes
It is low due to the use of frequency with the service life, so the blade 82 as consumables, replacement cycle are also very long.On this basis, it is driving
Lubricator package 6 is increased in system, makes containing a small amount of oil gas in dielectric gas, can be that rotor 83 is lubricated with blade 82.
Required rotating speed different requirement during in order to meet the purging of gas turbine and igniting, in gas turbine front-end of spindle
And end setting velocity sensor（See attached drawing 2）, the opening and closing of solenoid valve decision pressure-regulating valve 2 is controlled by the rotating speed of feedback,
It opens during purging, is closed after meeting purging, open when rotating speed meets igniting demand and closed after accelerating to self-sustain speed.
During work, air source is connected to pipeline and bracket assembly by air source flange 1, and pressure is adjusted by pressure-regulating valve 2,
It lubricates by lubricator package 6, enters from the inlet flange of the inlet end of air motor 8.Blade 82 is inserted in the radial direction of rotor 83
It is moved freely in slot, makes blade 82 against stator 81 by air pressure and centrifugal force to ensure sealing and volumetric efficiency, blade
The pressure energy of compressed air is converted into the mechanical energy of rotation by 82 drive rotors 83, is then discharged from air motor air outlet slit 9.
Key connection gas turbine drives on rotor
Torque is transmitted in the inside of freewheel clutch in gear-box 10 by freewheel clutch, drives the rotation of gas turbine main shaft
Go to self-sustain speed.It can achieve the effect that start driver disengages with main shaft when directly cut-out compressed air；
Solenoid valve can be controlled to determine the opening and closing of pressure-regulating valve by the rotating speed of feedback, when purging opens, closes, treat after meeting purging
It opens when rotating speed meets igniting demand and is closed after accelerating to self-sustain speed.
Air source is connected to pneumatic horse by the utility model gas turbine Pneumatic drive system by pipeline and bracket assembly
It reaches.By this structure combination, largely solves the compact spindle nose insufficient space brought of gas turbine structure
Problem, and air motor has higher starting torque, starts, stops, rapidly, convenient for control, but also with overload
Protective effect will not break down due to overload.During overload, motor is that rotating speed is reduced or stopped, and when overload releasing, immediately may be used
To run well again, the failures such as parts damage are not generated, can be fully loaded with that continuously run Wen Sheng smaller for a long time.System is whole
It is simple in structure, spark can not be generated at work, be can apply to explode, be radiated, the occasion of high temperature, more dirt, and can be used for sky
The environment of air exhaustion humidity, and the danger without electric leakage.System media is air, and the difficulty in unavailability, discharge is pollution-free.
