Description
Technical Field
The utility model relates to a fan technical field especially relates to a stator governing system.
Background
With the rapid development of recent industry, fans are more and more widely used in the fields of petroleum, chemical industry and the like, and meanwhile, the requirements for the fans are higher and higher, the existing fans can mostly guarantee high efficiency on the design working condition points, but because the working conditions are complex in the actual use process, the fans are difficult to keep on the design working condition points for a long time, when the fans deviate relative to the working conditions, if the fans are not adjusted, the use efficiency of the fans can be rapidly reduced, and the reliable operation of the fans is difficult to guarantee.
Under the normal operating condition of the fan, because of the production process requirements, the resistance of the system is changed, and the change of the resistance of the system causes that the fan can not run under the optimal working condition, and part of energy is wasted, so the angle of the guide vane needs to be adjusted during processing, but the guide vane has a complex structure when being adjusted, and the adjustment angle is limited, so the improvement is needed.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a stator governing system for overcoming the stator structure complicacy when adjusting, the limited not enough of angle regulation.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a stator governing system, includes the casing, be equipped with a core section of thick bamboo in the casing, equidistant rotation is connected with a plurality of stator on the core section of thick bamboo, the one end of stator runs through the lateral wall of casing and extends to one side of casing, the one end of stator is connected with transmission portion, the last regulating wheel that has cup jointed that rotates of transmission portion, connect through the cable wire between two adjacent regulating wheels, is equipped with adjusting device on one of them regulating wheel.
Preferably, the adjusting device comprises a belt wound on one of the adjusting wheels, a speed reducer is arranged on one side of the shell, and one end of the belt is connected to an output shaft of the speed reducer.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses this system changes the angle and the direction of advance soon of advancing, giving vent to anger through the stator rotation, makes the fan work in the best operating mode region all the time, reduces the system resistance transform, makes the availability factor of fan higher, to some special regional carbon dioxide, inert gas in sending out the district more, can rotate stator to 180, to this regional fresh air of carrying, guarantees the normal transport of air.

In the figure: the device comprises a shell 1, guide vanes 2, a transmission part 3, an adjusting wheel 4, a steel cable 5, a core cylinder 6 and a speed reducer 7.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples, which are provided for the purpose of illustration only and are not intended to limit the scope of the invention.
Referring to fig. 1-3, a guide vane adjusting system comprises a housing 1, a core barrel 6 is arranged in the housing 1, a plurality of guide vanes 2 are connected to the core barrel 6 in an equidistant rotating manner, the guide vanes 2 rotate left and right on the core barrel 6, one end of each guide vane 2 penetrates through the side wall of the housing 1 and extends to one side of the housing 1, one end of each guide vane 2 is connected with a transmission part 3, an adjusting wheel 4 is sleeved on the transmission part 3 in a rotating manner, the transmission part 3 is driven to rotate when the adjusting wheels 4 rotate so as to drive the guide vanes 2 to rotate, the guide vanes 2 can rotate by 0-90 degrees, two adjacent adjusting wheels 4 are connected through a steel cable 5, one adjusting wheel 4 is provided with an adjusting device, when the adjusting wheels 4 are connected through the steel cable, the rotation of one adjusting wheel 4 can drive the other adjusting wheels 4 to rotate, all the guide vanes 2 rotate simultaneously, the adjusting directions are, the pre-rotation angle and direction of air inlet and outlet are changed by the rotation of the guide vane 2, so that the fan always works in the optimal working condition area.
Referring to fig. 2, the adjusting device includes a belt wound around one of the adjusting wheels 4, a speed reducer 7 is disposed on one side of the housing 1, one end of the belt is connected to an output shaft of the speed reducer 7, one side of the speed reducer 7 is connected to a motor, and the speed reducer 7 drives the adjusting wheel 4 to rotate with a small amplitude, so as to prevent the rotation amplitude from being too large and to accurately control the rotation angle of the fan.
The utility model discloses in, at the fan during operation, when needing to rotate stator 2, speed reducer 7 begins work, speed reducer 7 drives the belt and rotates, the belt drives one of them regulating wheel 4 and rotates, because a plurality of regulating wheels 4 pass through cable wire 5 and connect, thereby can drive cable wire 5's rotation when regulating wheel 4 rotates and drive all the other regulating wheel 4 and rotate, regulating wheel 4 drives transmission portion 3 and rotates, transmission portion 3 drives stator 2 and rotates, thereby adjust stator 2's rotation, can adjust according to the energy-saving regulation of resistance, make the resistance of system reduce.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
