Mostly existing entry guide vane regulator is to adopt connecting rod, by the pneumatic actuator driving of rectilinear path, the angle that the driving mechanism of forming by connecting rod and numerous transmission part comes adjusting vane.This entry guide vane regulator power consumpiton is big, complex structure, and transmission part is more, the low precision of angle adjustment, the assembling difficulty height is limited to the structure and the foozle problem of crank-bar linkage, is prone to the locked phenomenon of transmission.
The model utility content
In order to solve the problem that existing regulator exists, the purpose of this utility model is to provide a kind of stability high, the entry guide vane regulator of the single shaft cantilever compressor that can regulate under the condition of not stopping.
The purpose of this utility model is achieved through the following technical solutions:
The utility model comprises stator shell, regulator mounting disc and suction cone, regulator mounting disc and suction cone are installed in the both sides of stator shell respectively, be evenly equipped with a plurality of stator blades on the inwall of stator shell, all be connected with a bevel gear outside the stator shell, on the blade footstalk of each stator blade, wherein arbitrary bevel gear is provided with the transmission shaft that is connected with pneumatic actuator; Be provided with awl gear ring with the bevel gear engagement driving in the side of the outer surface of stator shell, each bevel gear.
Wherein: described stator blade is axially uniform regulator, and blade is a spindle-type, the axis coplane of each blade footstalk, and an end of blade points to the axis of regulator respectively; Described blade footstalk is placed through the stator shell by bearing, and traversing through end and bevel gear key connect; Described regulator mounting disc is affixed by an end of screw and stator shell; Described suction cone is a frustum type, and the end that its diameter is bigger is provided with adpting flange, and suction cone is affixed by the other end of adpting flange and stator shell.
Advantage of the present utility model and good effect are:
1. degree of regulation height, good stability.The utility model is regulated the established angle of stator blade by the bevel gear and the engagement driving of awl gear ring, and then regulates the gas flow of import, can regulate under the condition of not stopping, simple in structure, the adjusting process more accurately, balance, safety, component are few, and are easy for installation.
2. work flexibly.Stator sharf of the present utility model can rotate flexibly to being distributed in stator shell inwall.
3. cost is low, the life-span is long.The utility model has been cancelled the driving mechanism of existing regulator, has replaced the Pneumatic actuator of rectilinear path with the pneumatic actuator of angle stroke, greatly reduces the regulator cost, has prolonged working life, has reduced maintenance expenses.
