Description
Technical field
The utility model relates to technical field of electricity, and in particular to a kind of air compressor machine constant pressure air feeding control system.
Background technique
Air compressor motor power is larger, and Starting mode mostly uses one triangle start of unloaded (unloading) star, load and unloading side
Formula is all instantaneous.This has air compressor machine on startup biggish starting current (4-7 times), to equipment when loading and unloading
Mechanical shock is larger；Not only cause mains fluctuations, compressed gas source can also be made to generate biggish fluctuation；This operation side simultaneously
Formula can also acceleration equipment abrasion, reduce the service life of equipment.Since the dragging motor of general air compressor itself cannot
Speed regulation, therefore directly cannot realize that reduction of speed adjusts the matching of output power using the variation of pressure or flow, motor is not permitted
Perhaps frequent starting causes motor when gas consumption is few still to want idle running, and waste of energy is huge.
Summary of the invention
Aiming at the shortcomings of the prior art, the utility model provides a kind of air compressor machine constant pressure air feeding control system.
The utility model is achieved through the following technical solutions.
A kind of air compressor machine constant pressure air feeding control system, including air compressor machine, which is characterized in that the system also includes pressure biographies
Sensor, PID controller, frequency converter；The air accumulator of the pressure sensor and air compressor machine connection, for detecting air compressor air storage tank
Interior pressure, and pressure value is fed back into PID controller；The PID controller is used to receive the pressure value of pressure sensor feedback,
And by the difference of calculated setup pressure value and the pressure value of feedback, control Signal Regulation output frequency is exported to frequency converter
Rate；The frequency converter is used to control the revolving speed of the motor of air compressor machine.
The advantageous effects of the utility model, the utility model provide a kind of air compressor machine constant pressure air feeding control system,
In the existing original control circuit of air compressor machine, is bypassed using frequency conversion, facilitate transformation；Can make air compressor motor realize soft it is soft
Stop, reduces starting impact, extend duration of service；Since air compressor motor running frequency is variable, realize air compressor machine according to
The size of gas consumption automatically adjusts motor speed, reduces air compressor motor and frequently loads and unload, to subtract by a relatively large margin
The operation power of small size motor, enables air compressor machine constant pressure air feeding, realizes energy-efficient purpose.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
As shown in Figure 1, a kind of air compressor machine constant pressure air feeding control system, including air compressor machine 1, pressure sensor 2, PID control
Device 3, frequency converter 4；Pressure sensor 2 is connect with the air accumulator 5 of air compressor machine, the signal output end and PID control of pressure sensor 2
The signal input part of device 3 connects, and pressure value is changed into mark for detecting pressure in air compressor air storage tank 5 by pressure sensor 2
Quasi- electric signal feeds back to PID controller 3；The output end of PID controller 3 connects the motor 6 of air compressor machine, PID control by frequency converter 4
Device 3 processed is used to receive the pressure value of the feedback of pressure sensor 2, and passes through the pressure value of calculated setup pressure value and feedback
Difference exports control Signal Regulation frequency converter output frequency to frequency converter 4；Frequency converter 4 is used to control turning for the motor 6 of air compressor machine
Speed makes the pressure value of feedback and setup pressure value difference be decreased to zero, reaches the requirement of air compressor machine constant pressure air feeding.
The utility model is to be bypassed between power supply MCCB and air compressor motor using frequency conversion, and frequency conversion bypass is equipped with starting
Button KM2.In use, powering on MCCB, press start button KM2, air compressor machine brings into operation from underloading, compressed air into
Enter air accumulator 5, the pressure value P of air accumulator 5 is changed into standard electric signal and sends PID controller 3 to by pressure sensor 2, with pressure
Power setting value P0 makes comparisons, and carries out operation by set PID control mode according to the size of difference, generates control signal and is sent to
Frequency converter 4 controls the working frequency and revolving speed of the motor 6 of air compressor machine by frequency converter 4, so that actual pressure P be made to approach always
Set pressure P0.After the utility model, air compressor motor can be started from static to rotary work by frequency converter, be realized
Soft start, avoids inrush current and air compressor machine bring mechanical shock is given in starting.In addition, the utility model can also protect
Staying original control and protection circuit, (i.e. power supply MCCB is connect with air compressor motor, and the circuit of connection is equipped with start button KM1
And electrothermal relay FR presses start button KM1 when carrying out power frequency startup), realize power frequency and frequency conversion handoff functionality.
Above-described is only the preferred embodiment of the utility model, does not limit to the utility model.It should be understood that for
For those skilled in the art, under technical inspiration provided by the utility model, it can also make and other equally change
Into the purpose of this utility model may be implemented, be regarded as the protection scope of the utility model.
