Abstract
The utility model provides an automatic running air compressor group assorted according to working conditions and relates to the field of controlling multiple air compressor groups. The multiple air compressors are connected with a PLC system via anticorrosion shielding prevention paired cables, and a pressure sensor is disposed on an air buffer tank to obtain feedback signals, thereby realizing automatic loading increase or standby of the air compressors according to working conditions, saving electric energy, lowering service time of the air compressors, prolonging service life of the air compressors, increasing reliability of the system, and reducing problems caused by insufficiency of process air, instrument air and nitrogen in the whole process. The air compressor group is simple in equipment, low in investment and fast in effect.
Description
Technical field
The utility model relates to the field that the multiple air compressors group is controlled, particularly a kind of pneumatics unit according to the operating mode automatic matching running.
Background technique
Our factory's air compressor delivery pressure operating range is between 0.65MPa-0.8MPa, when air cushioning jar outlet pressure is lower than 0.65MPa, air compressor is adjusted into the increment of load state system is pressurizeed, the air cushioning pressure tank is risen, system pressure increases thereupon, and when the knock out drum outlet pressure reached 0.8MPa, air compressor was adjusted into unloaded state, the corresponding meeting of the pressure of knock out drum decreases, air compressor periodic duty like this.Because whole system using gases amount is different, therefore the air cushioning pressure tank also can change from the period of waves of 0.65MPa-0.8MPa, if system's gas consumption is big, then the air cushioning pressure tank is just short period of waves, and the little then air cushioning of system's gas consumption pressure tank is just long period of waves.Under the little situation of whole system gas consumption, it is bigger that multiple air compressors moves waste simultaneously.
The model utility content
Technical problem to be solved in the utility model provides a kind of pneumatics unit according to the operating mode automatic matching running, can save electric energy, prolong air compressor working life, increases the reliability of system.
For solving the problems of the technologies described above, the technological scheme that the utility model adopted is: a kind of pneumatics unit according to the operating mode automatic matching running, comprise the air cushioning jar, the control section of at least three air compressors is connected with the output terminal of PLC by anticorrosion anti-shielded twisted pair, every air compressor is connected with the air cushioning jar, the air cushioning jar is provided with pressure transducer, and pressure transducer is connected with the input end of PLC.
Described pressure transducer has a plurality of.
A kind of pneumatics unit that the utility model provides according to the operating mode automatic matching running, by anticorrosion anti-shielded twisted pair multiple air compressors is connected with the PLC system, and pressure transducer is set on the air cushioning jar obtains feedback signal, automatic increment of load of multiple air compressors according to working conditions or standby have been realized, thereby saved electric energy, reduced air compressor service time, prolong air compressor working life, the reliability of increase system, make whole production because of process air, instrument supply gas, the possibility that the quantity not sufficient of nitrogen and causing goes wrong reduces, equipment is simple, invest little, instant effect.
Description of drawings
Fig. 1 is a flow chart of the present utility model.
Embodiment
In Fig. 1, a kind of pneumatics unit according to the operating mode automatic matching running, comprise the air cushioning jar, the control section of at least three air compressors is connected with the output terminal of PLC by anticorrosion anti-shielded twisted pair, every air compressor is connected with the air cushioning jar, the air cushioning jar is provided with pressure transducer, and pressure transducer is connected with the input end of PLC.
Described pressure transducer has a plurality of.
Embodiment:
Air compressor operating range in this example is at 0.65MPa-0.8MPa, when air cushioning jar outlet pressure is lower than 0.65MPa, air compressor is adjusted into the increment of load state system is pressurizeed, the air cushioning pressure tank is risen, system pressure increases thereupon, and when air cushioning jar outlet pressure reached 0.8MPa, air compressor was adjusted into unloaded state, the corresponding meeting of the pressure of knock out drum decreases, air compressor periodic duty like this.Because whole system using gases amount is different, therefore the air cushioning pressure tank also can change from the period of waves of 0.65MPa-0.8MPa, if system's gas consumption is big, then the air cushioning pressure tank is just short period of waves, and the little then air cushioning of system's gas consumption pressure tank is just long period of waves.
According to these characteristics, native system increases a PLC programming controller on the original basis, and by 485 communication modes and the original control system networking of pneumatics unit, control divides independent manually start and stop control and concentrates control automatically.Adopt wall-hanging instrument box, PLC is fixed on the interior guide rail of case.Pressure transducer adopts redundant fashion, two same model pressure transmitter pressures on the air cushioning jar, thus improved the reliability of system.485 connections adopt anticorrosion shielded twisted pair directly to link to each other with three generator set controllers, and PLC is by output control relay contact control unit operation.
Pressure transducer is transferred to the pressure surge situation on the PLC, be made as main frame by one in selected three air compressors of PLC system, selected main frame is in running order always, and two air compressors are in the unlatching holding state as subsidiary engine in addition, is reduced to the first threshold pression value a under knock out drum pressure continues
1During for 0.62MPa, PLC sends instruction, increases a subsidiary engine operation, still descends as pressure, drops to the second threshold pression value a
2During for 0.60MPa, then main frame sends instruction and will remain a unit unlatching operation.
When system's gas consumption changes, when for example gas consumption reduces, the cycle of air compressor increment of load operation and the unloading operation cycle stretch-out that will change, thereby making the air cushioning pressure tank be 0.8MPa to lower limit a from the upper limit b that sets is to change the period of waves of 0.65MPa, when the time lengthening of air cushioning pressure tank period of waves when setting value T is 1 minute and 30 seconds, the PLC system sends instruction, stop a subsidiary engine operation, after two subsidiary engines stop a job, when time period of waves of air cushioning pressure tank still reaches setting value T and is 1 minute and 30 seconds, main frame sends instruction and stops an other random job, and makes random be in holding state.When selected main frame need overhaul, PLC was set at main frame with a subsidiary engine wherein automatically.
When PLC normally moves; the priority of the logical address of distributing according to three air compressors is carried out main auxiliary machine and is distributed; the pressure that the PLC program is gathered according to pressure transducer comes automatic start and stop group; error protection is set; when any unit fault or maintenance; system directly cuts the control of this unit, incorporates system automatically into up to the state rear that resets.When PLC breaks down, directly switch to manual mode by " manual " diverter switch, this moment, 3 air compressors can independent operating.
Present embodiment has only been described the networking situation of three air compressors, but adopts this method also can control more air compressor, only needs to set up more low pressure limit value, and the pneumatics unit of therefore controlling more ought to be also within the protection domain of this patent.
