Description
Technical field
The utility model relates to the control gear of compressor operation, especially a kind of intelligent controlling device controlling multiple air compressors and run.
Background technique
Tradition compressor operation controls comparatively simple, air compressor is once startup optimization, its motor is just in power frequency operating condition, it runs and controls mainly to come controlled loading and unloading by air door, load or unload is frequently needed in real-world operation process, and unloading process in air compressor be do not produce compressed-air actuated, and unloading process in air compressor also need the electricity consuming its rated power about 60%.Therefore its power consumption is comparatively large, and wattless power accounting is comparatively large, and simultaneously because of load or unload frequently, can cause greater impact to air compressor itself and electrical network, and supply gas pressure is unstable, when particularly multiple air compressors runs air feed simultaneously, its delivery pressure stability is poorer.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of intelligent controlling device controlling multiple air compressors and run, and realizes the intelligent control run multiple air compressors, both energy-conservation, makes again supply gas pressure stablize.
For achieving the above object, the technical solution of the utility model is: a kind of intelligent controlling device controlling multiple air compressors and run, comprise PLC, frequency variator, the motor of every platform air compressor connects external power supply by first contactor, and the motor of every platform air compressor connects frequency variator by second contactor, all first contactors and the second contactor control closed by PLC or disconnect, producing, pressurized air is unified flows to a pressurized container to all air compressors, a pressure transducer this pressurized container is equipped with, pressure transducer is transferred to PLC pressure signal, PLC makes a wherein air compressor be connected frequency variator by controlling all first contactors with the closed of the second contactor or disconnection, then PLC exports control signal to frequency variator according to the pressure signal received compared with the force value preset, frequency variator exports corresponding frequencies according to the control signal of PLC and controls the running speed being attached thereto air compressor motor.
Further improvement, the circuit connecting external power supply is provided with main switch.
Further improvement, all air compressors flow to a cooling driers producing pressurized air first unification, and cooling driers gives pressurized container compressed air delivery again.Cooling driers utilizes refrigerant and pressurized air to carry out heat exchange, compressed air temperature is dropped to the dew point temperature of 2 ~ 10 DEG C of scopes, makes water content in pressurized air be tending towards super-saturated state, thus the moisture in removing pressurized air.Can quality of filling gas be improved like this, guarantee the accuracy of pressure transducer detected pressures in pressurized container further.
Further improvement, also comprises the 3rd contactor, and PLC controls the closed of the 3rd contactor or disconnect to make frequency variator connect external power supply or disconnect with external power supply.Frequency variator can be made to be in off working state by the disconnection of the 3rd contactor, both energy-conservation, can frequency variator be protected again.
The utility model controls the closed or disconnection of all first contactors and the second contactor by PLC, any air compressor just can be made at power frequency operation or converting operation or do not run three kinds of states and switch, realizing the intelligent control that multiple air compressors runs.Secondly, air compressor, without the need to load or unload frequently, reduces the impact caused air compressor itself and electrical network, and extend the working life of air compressor, effectively improve power factor, energy-saving effect is obvious.On the other hand, by making a wherein air compressor be in converting operation state, can better regulation output tolerance, guarantee the stable of pressure in pressurized container, supply gas pressure is stablized.
Accompanying drawing explanation
Fig. 1 is the utility model structure principle chart.
Embodiment
Below in conjunction with accompanying drawing and concrete mode of execution, the utility model is described in further detail.
Shown in Fig. 1, a kind of intelligent controlling device controlling multiple air compressors and run, comprise PLC 1, frequency variator 2, two air compressors 3, the motor of every platform air compressor 3 connects external power supply by first contactor 4, and every platform air compressor 3 motor connects frequency variator 2 by the second contactor 5; All first contactors 4 and the second contactor 5 control closed by PLC 1 or disconnect;
Producing, pressurized air is unified first flows to a cooling driers 6 to all air compressors 3, cooling driers 6 utilizes refrigerant and pressurized air to carry out heat exchange, compressed air temperature is dropped to the dew point temperature of 2 ~ 10 DEG C of scopes, water content in pressurized air is made to be tending towards super-saturated state, thus the moisture in removing pressurized air, cooling driers 6 gives a pressurized container 7 compressed air delivery again, and pressurized container 7 again air feed uses to production line;
Pressurized container 7 is equipped with a pressure transducer 8, pressure transducer 8 is transferred to PLC 1 pressure signal, PLC 1 makes a wherein air compressor 3 be connected frequency variator 2 by controlling all first contactors 4 with the closed of the second contactor 5 or disconnection, then PLC 1 exports control signal to frequency variator 2 according to the pressure signal received compared with the force value preset, and frequency variator 2 exports corresponding frequencies according to the control signal of PLC 1 and controls the running speed being attached thereto air compressor 3 motor; When the pressure signal that PLC 1 receives is greater than setup pressure value, frequency variator 2 output frequency reduces, and reduces the running speed being connected air compressor 3 motor with frequency variator 2, reduces the output tolerance of air compressor 3; When the pressure signal that PLC 1 receives is less than setup pressure value, frequency variator 2 output frequency increases, and increases the running speed being connected air compressor 3 motor with frequency variator 2, strengthens the output tolerance of air compressor 3; So just can guarantee the stable of compressed air pressure in pressurized container 7, supply gas pressure be stablized, and energy-conservation effect can be got.
The present embodiment is provided with main switch 9 on the circuit connecting external power supply.
