Abstract
The utility model discloses an electric drive fixed blade adjusting mechanism of an axial-flow compressor, which includes a casing of the axial-flow compressor. An adjusting cylinder, a half loop, a sliding block, guiding rings of all levels, a crank and a fixed blade are arranged in the casing of the axial-flow compressor. The electric drive fixed blade adjusting mechanism is characterized in that an electric actuator is further arranged on the casing of the axial-flow compressor and mounted on one side of the casing of the axial-flow compressor through a pedestal; the torque output by the electric actuator is transformed into axial thrust through an output shaft, the half loop and the sliding block, so as to drive the adjusting cylinder to do axial reciprocating motion; the adjusting cylinder drives the guiding rings of all levels and the sliding block inserted in the guiding rings to move together; the fixed blade is driven by the sliding block through the crank, and the angle change of the fixed blade can adjust the flux and the pressure. The electric drive fixed blade adjusting mechanism of the axial-flow compressor is used for adjusting the flux and the pressure of the axial-flow compressor, and meeting the demand of the technological process; the structure thereof is simple; and the maintenance is convenient.
Description
Technical field
The utility model relates to a kind of axial flow compressor stator blade controlling mechanism, particularly a kind of motorized motions stator blade controlling mechanism of axial flow compressor, and this motorized motions stator blade controlling mechanism can be regulated the stator blade of axial flow compressor.
Background technique
Axial flow compressor is a kind of turbomachinery equipment that pressurized gas is provided, and is the important motivity equipment of large-scale air feeds such as smelting, oil, chemical industry, pharmacy, environmental protection, gas compression.Equipment in use, except condition for import can change (atmosphere environment etc.), because the requirement of technological process, parameters such as the pressure of pressurized gas and flow also need to change.Like this, compressor will adapt to the variation of this working condition, must change the operating mode (being variable parameter operation) of operation.Axial flow compressor will be regulated working conditions change, must could satisfy parameters such as pressure and flow and change requirement by changing the angle of stator blade.Conventional stator blade controlling mechanism has: gear and rack drives stator blade controlling mechanism and hydraulic driving stator blade controlling mechanism.Gear and rack drives stator blade controlling mechanism, it is lower that it regulates remolding sensitivity, and degree of regulation is poor; Hydraulic driving stator blade controlling mechanism, its governing speed is fast, but the system architecture complexity, stator blade is regulated and is easy to generate drift.
Summary of the invention
