Abstract
The utility model discloses a highly-efficient energy-saving centrifugal fan. The highly-efficient energy-saving centrifugal fan includes a casing, an air inlet, an impeller, a transmission shaft, a bearing pedestal, a transmission shaft belt pulley, a motor, a motor belt pulley and an integrated type bracket. The highly-efficient energy-saving centrifugal fan is characterized in that the transmission shaft is mounted on the bearing pedestal, the impeller is mounted at one end of the transmission shaft, the transmission shaft belt pulley is mounted at the other end of the transmission shaft, the air inlet is fixedly mounted on the casing, the bearing pedestal, the casing and the motor are mounted on the integrated type bracket in an assembled manner, and the transmission shaft belt pulley is connected with the motor belt pulley through a belt. The highly-efficient energy-saving centrifugal fan has the advantages that the impeller is made of aluminum alloy with low mass, and the transmission shaft belt pulley at one end of the transmission shaft has the inertia effect during rotation, so that the self-load of the highly-efficient energy-saving centrifugal fan is reduced during rotation; the motor is a variable-frequency motor, so that the air pressure and volume can be adjusted through the speed regulation function of the variable-frequency motor to further achieve the purposes of high efficiency and energy conservation.
Description
Technical field
The utility model belongs to centrifugal blower equipment technical field, particularly relates to a kind of energy-efficient centrifugal blower.
Background technique
The design of tradition centrifugal blower flow all designs with maximum quantity of wind demand, its adjustment mode adopts the modes such as barge board or air door air-valve current-carrying to control, and cannot form closed loop and control, and does not also more consider the idea of power saving, the problems such as ubiquity power consumption is large, and overall efficiency is low.
Summary of the invention
Not enough in order to overcome above-mentioned prior art, the problem such as the utility model provides a kind of energy-efficient centrifugal blower, solves existing centrifugal blower power consumption large, and overall efficiency is low, thus reach energy-efficient object.
The utility model solves the technological scheme that its technical problem adopts: a kind of energy-efficient centrifugal blower comprises casing, intake grill, impeller, transmission shaft, bearing support, transmission shaft belt pulley, motor, motor pulley, integrated support, belt.It is characterized in that: transmission shaft is arranged on bearing support, one end of transmission shaft is provided with impeller; The other end is provided with transmission shaft belt pulley.Intake grill is fixedly mounted on casing.Bearing support and casing and motor combination are arranged on unit frame, and sectional flywheel skin wheel is connected by belt with motor pulley.
The beneficial effects of the utility model are:
1, impeller is selected the aluminum alloy that quality is light, has alleviated the load of blower fan self while rotating, thus can not reduce reduction motor power (output) suitable under the prerequisite of blast and air quantity, thus reached energy-saving and cost-reducing object.
2, transmission shaft belt pulley adopts flywheel assembly belt pulley, and having transmission agency has increased again the inertia while moving, thereby has increased efficiency, has reduced energy consumption.
3, the motor in the utility model adopts adjustable frequency motor as power source, has realized on the one hand the variation of automatic adaptation load behavior, and the speed-regulating function by adjustable frequency motor regulates blast and air quantity on the other hand, has saved power supply.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Fig. 1 is overall structure plan view of the present utility model;
Fig. 2 is overall structure side view of the present utility model;
1. casings in figure, 2. intake grill, 3. impeller, 4. transmission shaft, 5. bearing support, 6. flywheel assembly belt pulley, 7. motor, 8. motor pulley, 9. integrated support, 10. belt.
Embodiment
As Fig. 1,2, as shown in: a kind of energy-efficient centrifugal blower comprises casing, intake grill, impeller, transmission shaft, bearing support, transmission shaft belt pulley, motor, motor pulley, integrated support, belt.It is characterized in that: transmission shaft is arranged on bearing support, one end of transmission shaft is provided with impeller; The other end is provided with transmission shaft belt pulley.Intake grill is fixedly mounted on casing.Bearing support and casing and motor combination are arranged on unit frame, and sectional flywheel skin wheel is connected by belt with motor pulley.
During this real Novel work, the motor pulley that install motor one end drives the transmission shaft belt pulley that is arranged on transmission shaft one end to rotate by belt, thereby makes the impeller of the transmission shaft the other end realize interlock.Because the utility model impeller has been selected the aluminum alloy that quality is light; And the effect of inertia of the transmission shaft belt pulley of transmission shaft one end during due to rotation, the load of self while making the energy-efficient centrifugal blower of the utility model alleviate rotation; When motor adopts adjustable frequency motor to make the energy-efficient centrifugal blower of the utility model reach the required air pressure air flow of operating mode as power source, motor is adjusted power consumption automatically, speed-regulating function by adjustable frequency motor regulates blast and air quantity on the other hand, thereby reaches its energy-efficient object.
