1) calculated according to corresponding rated discharge amount when the specified power of air compressor machine, pressure between capacity and frequency
Corresponding relation, controller record frequency of the air compressor machine in stable situation and correspondingly go out a gas consumption；
2) controller monitors the capacity before the real-time ventilation amount of air compressor machine, particularly air compressor machine dormancy in real time；
3) controller record and monitoring air compressor machine dormancy time；
When 4a) dormancy time is long, illustrate that user's gas consumption is small, during wake-up, controller is sentenced according to record in step 2)
It is fixed, the upper limiting frequency of complete machine operation of air compressor machine is reduced to reasonable value, ensures to wake up voltage stabilizing when starting, while do not influence user
Use；
4b) dormancy time in short-term, illustrates that user's gas consumption is big, and during wake-up, controller is sentenced according to record in step 2)
It is fixed, the upper limiting frequency of complete machine operation of air compressor machine is improved to reasonable value, and it is frequent that increase capacity avoids dormancy from starting, and ensures simultaneously
User's uses gas；
5) air compressor machine is adjusted according to the gas consumption in step 1) into PID.
Wherein：
PID regulations refer to：
Pair between capacity and frequency is calculated according to corresponding rated discharge amount when the specified power of air compressor machine, pressure
It should be related to, frequency of the record air compressor machine in stable situation correspondingly goes out a gas consumption and carry out the compressor operation upper limit
Setting, make air compressor machine dormancy when user's gas consumption is smaller suddenly, adjust what is set with air compressor machine according to PID after air compressor machine wake-up
Upper limiting frequency is run；
In the present invention, controller is run according to the capacity (i.e. stable operation frequency) before air compressor machine dormancy and dormancy
Duration calculation goes out a rational frequency, and carrying out operation according to this rational frequency in air compressor machine dormancy awakening enters back into
PID is adjusted, and such air compressor machine is with regard to that can rapidly enter stable operation after dormancy awakening, and it can reach following purpose：
1) gas consumption of dormancy time length explanation user is small, can reduce upper limiting frequency when air compressor machine is restarted, so both
Steady pressure that can be quickly can also save the energy；
2) gas consumption of the short user of dormancy time is big, appropriate raising upper limiting frequency, reduces time for short time dormancy occur
Number, reduces the injury to air compressor machine.
Compared with prior art, a kind of air compressor machine dormancy control method of the invention, its using air compressors and
PID regulations coordinate the dormancy control for realizing air compressor machine, reduce dormancy and the wakeup frequency of air compressor machine, reduce the damage to air compressor machine
Wound, improve the service life of air compressor machine.
