Background technique
Axial flow compressor stator blade servo-system is that axial flow compressor is realized control automatically and the key and the core of regulating, particularly convert the electrical signal to the electrohydraulic control of hydraulic pressure signal and the servomotor of output mechanical force, its performance directly influences the working stability of compressor.
China is from introducing axial flow compressor, is applied in stator blade and regulates electrohydraulic control in the servo-system, and what the initial stage adopted is the servovalve of MOOG series or homemade YFW10 series, but this type of valve stops up easily, and resistance tocrocking is poor.Up to the mid-90 in last century, because the user is to the high request of electrohydraulic control resistance tocrocking, begin to use the BD series product of introducing the U.S., and progressively in the axial flow compressor product, obtain promoting, although the resistance tocrocking of BD series product is than the serial or homemade YFW10 series of servo of MOOG valve height, but its resistance tocrocking still has deficiency, and particularly the line between its controller and the servovalve is long, and signal degradation is serious.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, a kind of servo control set for adjusting of axial flow compressor variable stator vane angle is proposed, this device no longer needs independently controller, band PID regulatory function and servovalve are integrated, the level of integration height, the problem, the control loop that have solved signal degradation simultaneously are simple, and field adjustable is easy to operate, and have the high characteristics of resistance tocrocking.
The technical solution of the utility model is achieved in that a kind of control set for adjusting of axial flow compressor variable stator vane angle, comprise and be installed in an axial flow compressor lower housing left side, the angular displacement transmitter ZT of right servo-cylinder SM bottom, the angular displacement mechanical signal input end of angular displacement transmitter ZT and the mechanical displacement output terminal of servo-cylinder SM are connected by shift fork, the analog signal output of angular displacement transmitter ZT is connected with the input end of distributor ZY, the output terminal of distributor ZY is connected with the input end of PID controller, the integrated formation integral type of PID controller and electrohydraulic control electrohydraulic control SV, this integral type electrohydraulic control SV is connected with servo-cylinder SM by the oil circuit distributor.The PID controller directly drives the spool of electrohydraulic control SV by signal operation, comparison, amplification conversion, changes the valve position of spool, reaches control hydraulic oil and enters the oil mass of servo-cylinder SM, and enter the direction of the ante-chamber or the back cavity of oil cylinder.Thereby drive the piston motion of servo-cylinder SM, the piston rod of servo-cylinder SM is connected with the adjusting cylinder of variable stator vane angle, reaches the purpose of the adjusting control of stator blade.
Because the utility model has adopted present advanced person's integral type electrohydraulic control, PID regulator and servovalve are integrated, have solved the problem of signal degradation; Adopted new oil circuit distributor, the level of integration height, so this device has the resistance tocrocking height, the no signal decay, control loop is simple, and field adjustable is easy to operate simultaneously, has improved the reliability of system, the advantage of practicability.
