Abstract
The utility model discloses a draught fan with a vibration-reduction system. The draught fan with the vibration-reduction system comprises a water cooling fan, a PLC, a vibration transmitter and a frequency converter, wherein the vibration transmitter is respectively connected with the water cooling fan and the PLC, and the frequency converter is respectively connected with the water cooling fan and the PLC. The rotation speed of the draught fan can be lowered when the draught fan vibrates, so that the rotation centrifugal force of an impeller of the draught fan is reduced, the deformation amount of the impeller of the draught fan is reduced, and the purpose of achieving dynamic balance when the draught fan operates is achieved.
Description
Technical field
The utility model relates to a kind of glass-fiber industry blower fan used, relates in particular to a kind of blower fan that subtracts the system of quivering that has.
Background technique
The air-blower control prior art adopting on glass smoldering furnace only adds the break-make that a frequency variator is manually adjusted rotating speed or directly manually controlled blower fan with air-break switch mostly, allows blower fan be operated in the full load condition of 50 hertz; And monitoring to blower fan temperature and cyclic hydrostatic pressure relies on artificial timed patrol inspection mostly, has increased staff's labor intensity and administration cost.Impossible in the confidential object that reaches steady and continuous running of this technical specifications leeward.
Existing draught fan impeller works long hours under glass smoldering furnace 500 celsius temperatures inevitably can there is deformation and intensity decline, the centrifugal force producing because of rotation in the time running up will make dynamic balancing meeting that unsettled variation occurs, smoldering furnace is considered air output in the time of design, the gap of smoldering furnace wall and draught fan impeller is less, once impeller generation dynamic balancing changes, will there is the accident of being rebuffed, easily cause the damage of body of heater damage and draught fan impeller, thereby blowing out accident occurs, and this is that glass smoldering technique is unallowed.
When prior art scheme changes blower fan generation dynamic balancing; equipment does not have the malfunction alarms such as cooling water interruption and automatic reduction of speed to dispose the ability that dynamic balancing changes; can cause damage to impeller and furnace wall; blower fan self also may be because recirculated cooling water interrupts burning, the economic loss that causes equipment downtime accident and produce.
Separately there is China Patent No. to be: CN201120016581.X discloses the model utility that denomination of invention is fan special for complete type grate cooling machine, and this model utility fan special for complete type grate cooling machine comprises centrifugal blower 1, variable-frequency motor 2, integral shock-absorbing base 3, frequency-changing control system 4, sound insulation noise elimination filter 5, operation display panel 6.It is not to control the rotating speed of blower fan dynamically.
Model utility content
In order to overcome the defect of above-mentioned existing technology, the utility model provides a kind of blower fan that subtracts the system of quivering that has, when trembling, can reduce by this blower fan the rotating speed of blower fan, thereby reduce the centrifugal force of draught fan impeller rotation, thereby reduce the deformation quantity of draught fan impeller, reached dynamically balanced object while stablizing blower fan running.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of have a blower fan that subtracts the system of quivering, it is characterized in that: comprise water-cooling fan, PLC controller, vibration transmitters and frequency variator, described vibration transmitters is connected with water-cooling fan and PLC controller respectively, and described frequency variator is connected with water-cooling fan and PLC controller respectively.
Described vibration transmitters is connected with the end cap of the rear end of water-cooling fan.
Also involving vibrations warning light, described vibration alarming lamp is connected with PLC controller.
The utlity model has following advantage:
1, the utility model comprises water-cooling fan, PLC controller, vibration transmitters and frequency variator, described vibration transmitters is connected with water-cooling fan and PLC controller respectively, described frequency variator is connected with water-cooling fan and PLC controller respectively, when water-cooling fan work, vibration transmitters constantly gathers blower fan displacement data input PLC controller, PLC controller is established existing test data model, in the time that the displacement data (or vibration data) of water-cooling fan exceeds in PLC controller data with existing, PLC controller sends instruction to frequency variator, reduce the rotating speed of water-cooling fan impeller, reduce the centrifugal force of vane rotary, thereby reduce the deformation quantity of water-cooling fan impeller, reach dynamically balanced object while stablizing blower fan running.
2, in the utility model, vibration transmitters is connected with the rear end cover of water-cooling fan, and because water-cooling fan is in running, its rear end Oscillation Amplitude is larger, is convenient to vibration transmitters image data, effectively controls trembling of blower fan.
3, in the utility model, go back involving vibrations warning light, described vibration alarming lamp is connected with PLC controller, in the time that the vibration of water-cooling fan exceedes the existing test data model of PLC controller, PLC controller can be indicated vibration alarming lamp, to remind operator, the now vibration of blower fan, in abnormal state, need enforce vigilance.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Mark in figure: 1, water-cooling fan, 2, PLC controller, 3, vibration transmitters, 4, frequency variator, 5, vibration alarming lamp.
Embodiment
Further illustrate mode of execution of the present utility model below in conjunction with accompanying drawing:
Embodiment 1
As shown in Figure 1, a kind of have a blower fan that subtracts the system of quivering, it comprises water-cooling fan 1, PLC controller 2, vibration transmitters 3 and frequency variator 4, vibration transmitters 3 is connected with water-cooling fan 1 and PLC controller 2 respectively, and described frequency variator 4 is connected with water-cooling fan 1 and PLC controller 2 respectively.When this water-cooling fan work, vibration transmitters 3 constantly gathers blower fan displacement (or vibration) data input PLC controller 2, and PLC controller 2 is established and is preset with test data model, in the time that the displacement data (or vibration data) of water-cooling fan 1 exceeds PLC controller 2 interior data with existing, PLC controller 2 sends instruction to frequency variator 4, reduce the rotating speed of the impeller of water-cooling fan 1, reduce the centrifugal force of vane rotary, thereby reduce the deformation quantity of the impeller of water-cooling fan 1, reached dynamically balanced object while stablizing water-cooling fan running.
Further, for ease of vibration transmitters image data, effectively control trembling of cold water blower fan, because the general amplitude of end cap of cold water blower fan rear end is larger, vibration transmitters 3 is connected with the end cap of the rear end of water-cooling fan 1.
Further, also involving vibrations warning light 5, described vibration alarming lamp 5 is connected with PLC controller 2, in the time that the vibration of water-cooling fan 1 exceedes the existing test data model of PLC controller 2, PLC controller 2 can be indicated vibration alarming lamp, to remind operator, the now vibration of blower fan, in abnormal state, need enforce vigilance.
