Abstract
An adjusting control device comprises a guide vane device, one end of the guide vane device is provided with a blower fan, the other end is provided with an air inlet pipe, the upper end of the guide vane device is provided with an adjusting electric performer; and the adjusting electric performer is connected with a PLC controller. The disclosed adjusting control device can control the adjusting electric performer according to air amount change, make vanes of the guide vane device rotate, and make pre-rotation be completed before air enters into the blower fan, to establish a required speed filed.
Description
Technical field
The utility model relates to a kind of Fan Equipment, particularly a kind of control set for adjusting.
Background technique
Existing guide vane device is connected with the blower one, during use, whatsoever the situation guide vane device turns round always, pressure condition and gas density have a significant impact the blower wind supply quantity, and especially blower easily produces surge, air density change under the off-design operating mode, pressure causes variation, need to regulate, and consume the meaningless energy, increased cost.
The model utility content
Goal of the invention: for the deficiencies in the prior art, the utility model discloses a kind of control set for adjusting that can effectively regulate guide vane device operation and rotating speed.
Technological scheme: the utility model discloses a kind of control set for adjusting, comprise guide vane device, an end of guide vane device is provided with blower, and the other end is provided with suction tude, and the upper end of guide vane device is provided with regulating motor-driven actuator; Described regulating motor-driven actuator is connected with the PLC controller.
Described guide vane device guide vane device is made of valve body, bearing, blade, driving actuating device, shaft coupling flange five parts, drive actuating device and drive blade rotary, the adjusting vane angle, so that air is finished pre-rotation before entering blower, set up needed velocity field, make blower fan in broader range of flow, keep high design efficiency, particularly under the off-design operating mode, reach peak efficiency during operation.
Described regulating motor-driven actuator converts the electrical signal to the angular displacement of rotating shaft or a kind of servo-electric final controlling element of angular velocity, but have high efficiency, stable, controllability good, the response quick, highly sensitive high precision positioning control.
Described PLC controller can be controlled regulating motor-driven actuator along with blower air quantity changes.
Beneficial effect: the disclosed control set for adjusting of the utility model can be controlled regulating motor-driven actuator along with air quantity changes, and makes the guide vane device blade rotary, so that air is finished pre-rotation before entering blower, sets up needed velocity field.
Description of drawings
Accompanying drawing 1 is the structural representation of control set for adjusting.
