Technical field
The utility model belongs to the maintenance of coalmine ventilation electronic device, calibration field, specifically a kind of mining electronic wind table, air velocity transducer pick-up unit.
Background technology
Electronic device, the air velocity transducer that the sub-wind table of Coal Electricity is monitoring mining personnel indispensability is that the colliery must be equipped with the necessary component of " coal mine safety monitoring system ".Consumption is large, regularly or irregularly needs repairing, and this is with regard to the corresponding workload that increases the maintainer, simultaneously maintenance personal's technical merit also proposed higher requirement, traditional above two kinds of instruments detect, calibration, need wind-tunnel, multiple instrument, instrument, frock integrate carries out work, comprises multimeter, D.C. regulated power supply, frequency meter, reometer, wire etc., the use of multiple instrument and conversion, make maintenance become one and both took up space the work of losing time again.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of multi-functional wind table air velocity transducer failure diagnostic apparatus, and multiple maintenance tool or frock are become one, and has made things convenient for use, and the step that simplifies the operation has simultaneously reduced operation easier.
The utility model is achieved by the following technical solution: mining electronic wind table, air velocity transducer pick-up unit comprise the 220V input interface, connect the 220V alternating current by the 220V input interface, one road alternating current becomes direct current through the conversion of AC-DC power module, give transducer control circuit, operating voltage/electric current display module and the power supply of output frequency display module, transducer control circuit connecting fan output air speed value display module; Operating voltage/electric current display module connects the power supply output module; The power supply output module is given air velocity transducer power supply outside to be measured; Another road 220V alternating current is to inverter supply, and frequency converter is exported the coupling shaft flow fan; Transducer control circuit is connected with frequency converter, and axial flow blower connects the micro wind-tunnel.
The beneficial effects of the utility model are: large-scale standard construction of wind tunnel is carried out micro, whole small product size is dwindled greatly, control and measuring ability are accurate simultaneously, multiple Common Instrument, instrument, frock are rolled into one, realized that mining wind table, air velocity transducer detect, the convenience of calibration work, handled easily.
Description of drawings
The below further specifies the utility model with embodiment with reference to the accompanying drawings.
Fig. 1 is the utility model structural representation.
Among the figure: 1,220V input interface, 2, AC-DC power module, 3, frequency converter, 4, transducer control circuit, 5, operating voltage/electric current display module, 6, axial flow blower, 7, blower fan output air speed value display module, 8, power supply output module, 9, the micro wind-tunnel, 10, the output frequency display module.
Embodiment
As shown in Figure 1, mining electronic wind table, air velocity transducer pick-up unit, connect the 220V alternating current by 220V input interface 1, one road alternating current becomes direct current through the conversion of AC-DC power module 2, give transducer control circuit 4, operating voltage/working current display module 5 and 10 power supplies of output frequency display module, operating voltage/electric current display module 5 connects power supply output module 8; Power supply output module 8 is given air velocity transducer power supply outside to be measured; Output frequency display module 10 receives and detects the frequency signal of air velocity transducer output.Another road 220V alternating current is to frequency converter 3 power supplies, and frequency converter 3 is connected with axial flow blower 6, and blower fan is played the electricity supply and control effect; Simultaneously transducer control circuit 4 is controlled frequency converter 3 according to operating personnel's input value, and then Control Shaft flow fan 6 is according to different speed rotations, and axial flow blower closely is connected with micro wind-tunnel 9, then produces big or small distinguished and admirable of difference in the micro wind-tunnel.Blower fan output air speed value display module 7 shows current distinguished and admirable standard speed, wind table to be measured is put on the test fixture of micro wind-tunnel, the value of wind table displayed value and blower fan output air speed value display module 7 is compared, see whether wind table displayed value is correct, take blower fan output air speed value display module 7 as standard the wind table is carried out adjustment as variant; Also the connecting line of air velocity transducer can be connected with diagnostic equipment, then air velocity transducer is put on the test fixture of micro wind-tunnel, after it is working properly, by operating voltage/electric current display module 5, and output frequency display module 10, judge whether the basic parameter of air velocity transducer is normal, by transducer control circuit 4, export different wind speed, whether normal show with the parameters of the indicating value of observing air velocity transducer and front, export the air speed value display module such as wind speed indicating value and blower fan
7 is variant, as standard, the air velocity transducer indicating value carried out adjustment with blower fan output air speed value display module 7 displayed values.Micro wind-tunnel 9 normative reference large tunnel structural designs, rational in infrastructure, but volume only is 1/5 of large tunnel.Wind-tunnel is manually to produce and to control air-flow, with flowing of simulated flight device or object ambient gas, and can measure air-flow to a kind of pipe-like experimental facilities of the effect of object and observation physical phenomenon, it is to carry out the most frequently used, the most effective instrument of aerodynamic experiment.Producing distinguished and admirable blower fan is axial flow blower 6, by the accurate control of frequency converter 3 and transducer control circuit 4, can produce several wind tables, air velocity transducer calibration wind speed commonly used, the wind table of applicable multiple producer, the detection of air velocity transducer, calibration.
This device can be realized the measuring wind speed displayed value of wind table, air velocity transducer being carried out calibration, the detection of air velocity transducer frequency output signal; The detection of air velocity transducer operating voltage, working current; The survey of output frequency signal etc.
