Abstract
The utility model relates to an actual air quantity regulator for a centrifugal fan of an air-conditioner, which is provided with a guide plate on the inner wall of the spiral casing of the fan. The opening angle of the guide plate can be adjusted by a reversible motor through a traction rope to change the area of the air outlet in order to adjust air quantity. The utility model has simple device, low cost and good adjusting performance, which is convenient to accomplish automatic control.
Description
Affiliated technical field
The utility model relates to the practical volume adjusting apparatus of a kind of air-conditioner centrifugal blower.
Background technology
Central air conditioner system often requires the air quantity of air-conditioner to regulate along with the variation of load, is achieved energy-saving run.At present, technique known is: the method that changes rotation speed of fan, fans entrance stator, blower fan outlet air-valve.It is obvious to change rotation speed of fan adjusting air quantity energy-saving effect, and control is convenient, but the cost height, the maintenance requirement height; Fans entrance stator method is to regulate air quantity by changing fans entrance leaf grating angle, and energy-saving effect is more remarkable, but complex structure is awkward; Blower fan outlet air-valve is in the blower fan outlet control valve to be installed to consume pressure and reduce air quantity by increasing duct resistance, and this method energy-saving effect is poor, and can cause system fluctuation.
Summary of the invention
In order to overcome the deficiencies in the prior art, it is a kind of functional that the utility model provides, and cost is low, simple and practical air-conditioner centrifugal blower volume adjusting apparatus.
The aerodynamic experiment result of centrifugal blower shows, when draught fan impeller, spiral case size, when motor speed is all constant, the exhaust air rate of centrifugal blower is long-pending along with air outlet reduces and reduces, motor is moving, and rate is corresponding thereupon reduces, and the variation of blast is very little, this is a technical foundation of the present utility model, is different from known technology.
Its solution is: wall a slice deflector slightly littler in the long limit of centrifugal blower volute than spiral case width, and deflector is made of elastic metallic that certain intensity is arranged or plastic plate, and looking stroke size deflector inner end, outer end can be hinged with spiral case or fixedly connected.Deflector outer end one side fixed tractive, the rope other end is fixed on the axle that can reverse the slow traction motor.The opening angle of the controlled system deflector of control motor changes the fan outlet area and then regulates air quantity.
In the spiral case side travel switch is installed,, can be realized that the level that has of air quantity is controlled automatically by the control of deflector adjustment process displacement.The setting angle transmitter can be realized stepless automatic control.
Further improvement of the utility model is: do dynamically sealing in the both sides of deflector and the inner end when hinged with flexible materials such as plastics, rubber, cottons, with turbulent flow and the aerodynamic noise that reduces the deflector back side.
On the pull rope rightabout of deflector outer end, adorn balance weight, to improve the stationarity of regulating.
Deflector is contained on the spiral case minor face inwall.
Be contained on the duplex blower fan, wideer adjustable range is arranged.
The beneficial effects of the utility model are, change the air outlet area by the control deflector and regulate air quantity, and device is simple, and the air quantity adjustable range is wide, obvious energy conservation, and blast changes little, is convenient to realize automatic control.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the side view of an embodiment.
Fig. 2 is that the A of Fig. 1 is to view.
1. blower fans among the figure, 2. reversible slow speed motor, 3. pull rope, 4. deflector, 5. dynamic seal (packing), 6. balance weight.
The specific embodiment
In Fig. 1,2, deflector (4) is made of metal or plastic plate, width is slightly smaller than the spiral case of blower fan (1), the inner end is hinged or fixedly connected with spiral case, the dynamic seal (packing) (5) that flexible material is made when being hinged, deflector both sides and inner end is housed, deflector outer end one side fixed tractive (3), the rope other end is fixed on the axle of reversible slow speed motor (2), and motor rotates the opening angle that then can change the deflector outer end.Balance weight (6) is contained on the opposite direction of deflector outer end pull rope, regulates stability to improve.
Claims (5)
1. the practical volume adjusting apparatus of an air-conditioner centrifugal blower, it is characterized in that: inwall is installed a deflector identical with shell mould on the long limit of centrifugal blower volute, deflector is made of elastic metallic that certain intensity is arranged or plastic plate, its width is slightly smaller than the spiral case width, the inner end of deflector is hinged with spiral case or fixedly connected, outer end one side fixed tractive, the other end of rope are fixed on the axle that can reverse the slow traction motor, in the spiral case side travel switch or angle are installed and hand device over to.
2. the practical volume adjusting apparatus of air-conditioner centrifugal blower according to claim 1 is characterized in that: do dynamically sealing in the both sides of deflector and the inner end when hinged with flexible material.
