Abstract

The utility model discloses an intelligent energy-conservation control system for an air compressor. The intelligent energy-conservation control system for the air compressor comprises operating equipment, an air compressor set, a frequency converter and a center control server, wherein the frequency converter and the center control server control the air compressor set to work. The operating equipment is communicated with an air channel of the air compressor set. The air compressor set is electrically communicated with the frequency converter. A pressure sensor used for detecting pressure values is electrically connected to the operating equipment. The pressure sensor is electrically connected with a programmable logic controller. The programmable logic controller is electrically communicated with the frequency converter. The center control server monitors the operating equipment, the air compressor set and the frequency converter in real time in an industrial communication mode. The pressure sensor is used for detecting the pressure values of the equipment, and the frequency converter gives orders according to the pressure values and determines the number of air compressors needed for work, so that the rate of equipment utilization is higher, and electric energy is saved; meanwhile, real-time monitoring can be conducted on the equipment through the center control server, and therefore the labor intensity is reduced for workers; the equipment does not need to be started or stopped frequently, so that the service cycle of the equipment is longer.

Description

The air compressor set intelligent energy-saving control system

Technical field

The utility model belongs to the equipment control field, particularly a kind of air compressor set control system of more intelligent power saving.

Background technique

Fast development along with industrial technology; the power source of equipment is very extensive; comprise hydraulic transmission; pneumatic etc.; but pneumatic to have a cost compared to other power modes low; pollution-free; advantages such as easy care and being widely used; and air compressor is the power resources of pneumatic control; how to use and to control air compressor just extremely important; the most air compressor all is by the star delta reduced-voltage starting; the total head operation; control whether export source of the gas according to pressure; will certainly cause like this equipment energy consumption large; Utilization ratio is low, and waste of energy is serious, for saving power; need artificial start and stop equipment; increased like this workman's labor intensity, not foot phenomenon of air pressure may appear in the equipment frequent start-stop, and frequent start-stop can affect the working life of equipment simultaneously.

The technical problems to be solved in the utility model provides the long intelligent control system of a kind of energy-conservation, life cycle.

The model utility content

For solving the problems such as above-mentioned prior art equipment power consumption is large, labor intensity is high, the utility model adopts following technological scheme:

The utility model provides a kind of air compressor set intelligent energy-saving control system, comprise operational outfit, the pneumatics unit, frequency variator and the middle control server of the work of control pneumatics unit, described operational outfit is communicated with pneumatics unit gas circuit, described pneumatics unit and described frequency variator electrical communication, be electrically connected with the pressure transducer of detected pressures value on the described operational outfit, described pressure transducer be electrically connected with the programmable controller of PID computing function, described programmable controller and frequency variator electrical communication, be provided with the JAVA programmable device in the described middle control server, described middle control server passes through the industrial communication mode to operational outfit, the pneumatics unit, the frequency variator Real Time Monitoring.

As to improvement of the present utility model, described middle control server is with fault alarm function.

As to further improvement of the utility model, described middle control server is also with the data form printing function.

The beneficial effects of the utility model are: detect the equipment force value by pressure transducer, frequency variator sends instruction and determines several air compressor work of needs according to force value, Utilization ratio is higher, save electric energy, reduced cost, by middle control server equipment etc. has been carried out Real Time Monitoring simultaneously, reduce the manual detection cost, reduced workman's labor intensity, equipment is without the estovers frequent start-stop, and life of equipment is longer.

Description of drawings

Fig. 1 is a kind of embodiment's of the utility model frame structure schematic representation.

Embodiment

Describe preferred embodiment of the present utility model in detail below in conjunction with accompanying drawing.

See also Fig. 1; a kind of air compressor set intelligent energy-saving control system; comprise operational outfit 1; pneumatics unit 2; frequency variator 3 and the middle control server 4 of 2 work of control pneumatics unit; described operational outfit 1 is communicated with pneumatics unit 2 gas circuits; described pneumatics unit 2 and described frequency variator 3 electrical communication; be electrically connected with the pressure transducer 5 of detected pressures value on the described operational outfit 1; described pressure transducer 5 is electrically connected with programmable controller 6 with the PID computing function; described programmable controller 6 and frequency variator 3 electrical communication; pressure transducer 5 detects and records the force value of operational outfit 1; pressure transducer 5 is transferred to the force value that detects in the programmable controller 6; 6 pairs of force value data of programmable controller are carried out PID and are calculated; and a numerical value that calculates is transferred in the frequency variator 3; frequency variator 3 decides several air compressor work of needs according to this numerical value; so just can guarantee the equipment effective rate of utilization of air compressor; do not need whole operations can satisfy usage requirement; saved electric energy; be provided with JAVA programmable device 41 in the described middle control server 4; described middle control server 4 passes through the industrial communication mode to operational outfit 1; pneumatics unit 2; frequency variator 3 Real Time Monitorings; JAVA programmable device specifically; the certain JAVA program of 41 inputs; these JAVA programs can find the above-mentioned operational outfit of mentioning 1 by the industrial communication mode; pneumatics unit 2 and frequency variator 3; and then control this three equipment; realize the intellectuality of control; automation; long-range; need not manual detection; the efficient and the accuracy that detect have been improved; and traditional air compressor is to adopt the star triangle start; the total head operation; so just certainly will cause the air compressor utilization ratio low; energy consumption is large; the waste electric energy; increase user cost; and traditional air compressor is by the manual control start and stop; so just increased labor strength; the equipment frequent start-stop can reduce the working life of equipment; virtually increase user cost, adopted the soft control of frequency variator to address this problem.

In the utility model, described middle control server 4 is also with fault alarm function, and central control server 5 monitors certain device parameter and occurs when unusual, can send malfunction alarm, service worker will be keeped in repair accordingly according to malfunction alarm, improves maintenance efficiency, reduces the troubleshooting program.

In the utility model, described middle control server 4, just can print by telecontrol when needs file to detected data also with the data form printing function, and is more convenient efficient.

The utility model is simple in structure, can too much not increase equipment cost and drop into, and business burden is little, but the effect highly significant, the control service is to device real-time monitoring in the employing, and the automation and intelligentification degree of equipment is higher, reduce labor strength, improved working efficiency; Moreover to the soft control of equipment, the air compressor utilization ratio is higher, has saved electric energy by frequency variator, and equipment need not frequent start-stop, and life of equipment is longer.
