Abstract

The utility model provides a stationary blade adjusting system for an axial flow compressor. The stationary blade adjusting system comprises an adjusting cylinder, guide rings, a first servo oil cylinder and a second servo oil cylinder, wherein the guide rings are connected with a stationary blade crank; the guide rings are as much as stationary blades; each guide ring is respectively arranged on the adjusting cylinder and is arranged in one-to-one correspondence with the stationary blades; two servo oil cylinders are arranged on two sides of the axial flow compressor in an axial symmetry way based on the symmetry axis of a center line of the adjusting cylinder; and piston rods of the two servo oil cylinders are respectively connected with two side surfaces of the adjusting cylinder through a first connecting plate and a second connecting plate.

Description

A kind of stator blade regulating system of Axial Flow Compressor
Technical field
The utility model relates to Axial Flow Compressor, particularly a kind of stator blade regulating system of full stator blade adjustable axial-flow formula compressor.
Background technique
Axial Flow Compressor is a kind of turbomachinery equipment that pressurized gas is provided, and it utilizes the interaction of blade and gas, improves pressure and the kinetic energy of gas, and utilizes flow passage component in succession that air-flow is slowed down, and kinetic energy is changed into the raising of pressure.The important motivity equipment of the large-scale air feeds such as oil, chemical industry, metallurgy, environmental protection, pharmacy, ammonia processed, gas compression.The operation stability of axial flow compressor and operating mode using scope will directly determine production capacity and the quality of product of these industries that involve the interests of the state and the people.The complete adjustable axial flow compressor of stator blade is by the adjustment to static blade angle, the adjusting of realization to operating mode, make it have that efficient is high, flow is large, the advantage such as flow, pressure regulation range broadness, even flow field, surge margin are large, thereby whether the structure of stator blade regulating system is rationally most important, but the problem such as existing stator blade regulating system exists that governing speed is slow, poor accuracy, life-span are low.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of stator blade regulating system of regulating quick, stable, accurate, safe Axial Flow Compressor is provided.
The stator blade regulating system of Axial Flow Compressor described in the utility model, comprise and regulate cylinder, be used for the guide ring, the first servo-cylinder and the second servo-cylinder that are connected with the stator blade crank, the quantity of described guide ring is identical with the quantity of stator blade, each guide ring is arranged on respectively to be regulated on cylinder, and with stator blade corresponding installation one by one, two servo-cylinders are take the center line of regulating cylinder as symmetry axis, be arranged on axisymmetricly Axial Flow Compressor both sides, the piston rod of two servo-cylinders is connected with the bi-side of adjusting cylinder by the first joining plate, the second joining plate respectively.
the working principle of the stator blade regulating system of Axial Flow Compressor described in the utility model: after the control system of Axial Flow Compressor is sent static blade angle change signal, its hydraulic oil system provides satisfactory pressure oil to the first servo-cylinder and the second servo-cylinder, drive the piston synchronous motion of two servo-cylinders, the piston of two servo-cylinders is respectively by the first joining plate, the second joining plate drives the adjusting cylinder and moves along its axis, can drive each stator blade crank that is connected with each guide ring respectively in the process that the adjusting cylinder moves rotates, thereby each stator blade is rotated, change angle.
The utlity model has following beneficial effect:
1, the stator blade regulating system of Axial Flow Compressor described in the utility model adopts two servo-cylinders that axisymmetric is installed to drive the adjusting cylinders to move, thus can be fast, stable, accurate, the safe adjusting that realizes static blade angle.
2, the stator blade regulating system of Axial Flow Compressor described in the utility model is simple and reasonable for structure, is convenient to maintaining, is conducive to improve working life.
