Description
Technical field
The present invention relates to the Profile For Compressor Stator adjustable vane interlock regulation structure field at work of motor, combustion engine, specifically provide a kind of mandrel type multistage adjustable vane uniting and adjustment actuation mechanism.
Background technique
Current gas compressor ensures in the angle change of slow-revving surge margin by adjustable stator blade, and the progression of adjustable vane is different according to the specific design of the motor of different model.When adjustable vane progression is more, a pair pressurized strut of every grade of need provides power, inter-stage angle rule controls to be completed by the controller of respective passage, such design can provide maximum flexibility to be determined the optimum rule of inter-stage by test in development, but because pressurized strut is more, add supporting oil pipe and controller, be unfavorable for commercialization.
The independent regulation technology of existing stator at different levels, power resources are in pressurized strut at different levels, the control of angle rule is realized by control system, number of spare parts is many, supporting pipeline additionally takes up room, and control law needs software programming to realize, and during assembling, pressurized strut at different levels all needs whole bulge test, also need all again to demarcate to the angle of each grade blade and controling parameters before motor runs, work repetition and loaded down with trivial details.
Summary of the invention
The object of the invention is in order to simplified structure, realize interlock, spy provides a kind of mandrel type multistage adjustable vane uniting and adjustment actuation mechanism.
The invention provides a kind of mandrel type multistage adjustable vane uniting and adjustment actuation mechanism, it is characterized in that: described mandrel type multistage adjustable vane uniting and adjustment actuation mechanism, comprises one-level regulating arm 1, support 2, mandrel 3, secondary regulating arm 4, support 5, three grades of regulating arms 6, one-level pull bar 7, pressurized strut 8, secondary pull bar 9, three grades of pull bars 10;
Mandrel 3 is arranged on compressor casing by fitting seat, the interlock ring of one-level regulating arm 1, secondary regulating arm 4, three grades of regulating arms 6 and one-level pull bar 7, secondary pull bar 9, three grades of pull bar 10 connecting mandrels and adjustable stator blade at different levels;
Pressurized strut 8 action promotes mandrel 3 and rotates, drive the regulating arms at different levels be arranged on mandrel 3 to rotate simultaneously, drive the movement of pull bar at different levels, other one end of pull bar at different levels connects the interlock ring of stator blade, thus having driven the rotation of interlock ring, the angle of blade changes.
Described one-level regulating arm 1, secondary regulating arm 4 are consistent with the structure of three grades of regulating arms 6, are integral single piece structure.
Realize the interconnected of multistage adjustable vane by mandrel type uniting and adjustment actuation mechanism, only need a pair pressurized strut to provide adjustment power, reach the object simultaneously regulating multistage blade, and the angle rule between multistage blade meets optimum.Like this, have cured blade adjustments rule by mechanism on the one hand, decrease pressurized strut quantity on the one hand, reduce cost of production, decrease pressurized strut during assembling and suppress the step of demarcating with controller, reduce assembly cost, number of spare parts reduces the reliability also improving whole system in addition.
The key of uniting and adjustment mechanism is to make blade rotary angle at different levels simultaneously controlled, i.e. rule change on request.As when 1 grade of angle is α 1, the angle of 2 grades and 3 grades should be α 2 and α 3,1 grade of angle when being changed to α 1 ', and the angle of 2 grades and 3 grades should be α 2 ' and α 3 '.
Advantage of the present invention:
Mandrel type of the present invention multistage adjustable vane uniting and adjustment actuation mechanism, uniting and adjustment actuation mechanism regulates adjustable vane, blade adjustments rule is have cured on the one hand by mechanism, decrease pressurized strut quantity on the one hand, reduce cost of production, decrease pressurized strut during assembling and suppress the step of demarcating with controller, reduce assembly cost, number of spare parts reduces the reliability also improving whole system in addition.
