Description
Technical field
The utility model relates to a kind of improved equipment of air compressor, particularly can make the energy-conserving and environment-protective of air compressor, is used to control the VFC Energy Saving Control cabinet system of air compressor.
Background technique
Along with the development of global automatic technology, air compressor becomes the second largest power equipment of industrial enterprise, and air compressor is the power consumption rich and influential family, and energy-saving potential is very big, and occupancy volume is maximum on present conventional air compressor (non-frequency) market, is approximately more than 90%.It is operated in, and the time carries out in non-full load situation greatly; Frequent add unloading; Exhaust pressure fluctuates very big up and down, so, will produce power waste through traditional control mode; Thereby cause inefficiency, so how reducing the running energy consumption becomes the air compressor industry and chases after the problem at the eyebrows and eyelashes.
Traditional air compressor variable frequency energy saving reforming: on traditional air compressor, add frequency variator, change the circuit of original air compressor, can not well combine the air compressor performance characteristic, under the frequency converter timing pattern, work.Though this kind air compressor can play certain energy-conservation, its work is not very stable, and to site operation personnel's technical requirements than higher, the market popularization degree is not high; Changed original circuit,, had influence on the normal operation of air compressor just in case frequency variator goes wrong.Still this system below department releases through permanent research and development spy, it can the above institute of good treatment problem.
Air compressor energy-saving and frequency-variable control cabinet system: on common air compressor, increase the energy-saving and frequency-variable control cabinet and form the air compressor energy saving control system of frequency conversion in use.We have incorporated all control functions of air compressor on VFC, not only can control air compressor separately and realize converting operation, and PID control is more accurate, more energy-conservation like this.Adopt programmable logic controller (PLC) (PLC) control mode to act on frequency variator, make the control air compressor running of frequency variator safety and precise.Thereby accomplish air compressor smooth starting, constant voltage work, free parking.Reach safety, stable, energy-conservation to greatest extent.And having simplified wiring, general personnel just can realize operation according to operation instruction, very easily to marketing.
Summary of the invention
To above-mentioned technical problem, the utility model provides a kind of air compressor VFC energy-conservation cabinet system, and it can control all functions on the air compressor, can cross the point-to-point fixed-point operation of PID.For accomplishing the foregoing invention purpose; The utility model is achieved in that the energy-conservation cabinet system of a kind of air compressor VFC; It is to be made up of power supply, frequency variator, control cabinet, motor, air compressor; Described power supply is used for to frequency variator, control cabinet, motor, air compressor power supply, and described frequency variator, motor and air compressor unification are controlled by control cabinet, it is characterized in that: described control cabinet has incorporated all control functions of air compressor; Adopt the control of PID controller.
When technique scheme is further changed, in control cabinet, be provided with programmable logic controller (PLC) (PLC), described PLC controls is used to control frequency variator.In control cabinet, be provided with thermal module; Thermal module is used to show the temperature in the control cabinet.Between frequency variator and motor, also be provided with reactor, between power supply and frequency variator, be provided with eliminator.
Technique scheme is done further to improve, and it also comprises a can display device, and this can display device connects through datawire.
We have solved combining of control system of air compressor and converter technique; We have incorporated the control system of air compressor in frequency conversion tank, can independent fully control compressor operations, need not change the control system of original air compressor; Just can use, reduce the transformation risk; And it is more energy-conservation, more reliable.
We simplify control wiring, do not need the professional workforce just can realize reducing energy consumption, greatly reduce reforming cost, are easy to popularize market; Be suitable for the air compressor transformation of all brands.
