Embodiment:
The actuator of the adjustable guide-ring of oxygen compressor air inlet of the present invention, it comprises air intake stator driving mechanism and air intake stator lazy-tongs.
Fig. 1, shown in 2, described air inlet is adjustable guide-ring driving mechanism comprises that pneumatic piston actuating mechanism 1, drive link 2, connecting rod 3, crank 4, universal joint 5, position limit pin 6, snubber 7, adjustment pad 12 and driving mechanism frame 10 form.Wherein position limit pin 6 is installed on the oxygen compressor lower housing 8, and snubber 7 is installed on the active blade connecting rod 11, and initiatively guide vane link 11 and universal joint 4 are connected through bolt.When blade reached fully open position, position limit pin 6 contacted with snubber 7, stoped snubber 7 and active blade connecting rod 11 to rotate, and had realized preventing active blade backward rotation mechanical protection; In like manner, when carrying out the guide vane closing motion, when stator arrived the complete shut-down position, snubber 7 contacted with position limit pin 6, and having stoped initiatively, guide vane link 11 further moves.
Oxygen compressor import guide-ring is made up of inlet guide vane 24 and active inlet guide vane 25, must guarantee the synchronization motion of all blades of guide-ring.Oxygen compressor import guide-ring lazy-tongs are made up of deflector 13, composite bearing 14, adjustable connecting-rod 22, outer shroud joint shaft bearing 23, slip ring 18, connecting sleeve 26 and drive link 11.Slip ring 18 contacts with deflector 13 through rolling bearing 19, can freely rotate around the deflector longitudinal center line; Slip ring 18, adjustable connecting-rod 22, crank 17 and deflector 13 formation spatial four-bar mechanisms when guide-ring active guide vane 25 opens and closes, can drive crank 17 and rotate with slip ring 18, and then accomplish synchronous on-off action by slip ring 18 drive inlet guide vane.Owing to adopted rolling bearing 19, slip ring 18 slip resistance are very little; Adjustable connecting-rod 22 can be adjusted its length, has avoided the appearance of synchronous spatial four-bar mechanism dead center position.
The actuator of the adjustable guide-ring of oxygen compressor air inlet, its working principle is following: because crank 4 sense of rotation axis and guide-ring active blade connecting rod 11 axis sense of rotation do not overlap, adopt universal joint 5 to connect.When oxygen compressor driving or generation surge, pneumatic piston driving mechanism 1 is carried out action, drive cranks 4 through drive link 2, connecting rod 3 and turn over several angle, and then by universal joint 5, drive active guide vane link 11 rotates.When the active guide vane link rotates, drive guide-ring lazy-tongs crank 17, slip ring 18 rotations simultaneously, and then realize the synchronous on-off action of guide- ring stator 24,25.
Adopt technique scheme, utilize pneumatic piston driving mechanism 1,, realized the synchronous on-off action of oxygen compressor guide-ring guide vane 24 with active guide vane 25 through oxygen compressor guide-ring driving mechanism and guide-ring lazy-tongs as driving element.On the one hand, adopt snubber 7 and position limit pin 6, limited active blade connecting rod 11 and rotated, avoided the counter-rotating of guide-ring blade; On the other hand, adopted the slip ring 18 and adjustable connecting-rod 22 of band rolling bearing, surface friction drag is little and avoided the appearance of dead center position, can reliably realize the synchronization motion of guide-ring stator.
At first the air intake stator lazy-tongs are installed, adjustment adjustable connecting-rod 22 length L according to Fig. 4
2, guarantee that each stator of guide-ring can rotate synchronously flexibly.Secondly, initiatively stator drive link 11, connecting sleeve 26, snubber 7 are installed, and are manufactured position limit pin 6 at oxygen compressor lower housing 8 according to active stator complete shut-down, fully open position.In the 3rd step, air intake stator driving mechanism (like Fig. 1) is installed.
