Analysis of potential control technology of air compressor system

Potential analysis of air compressor system centralized control technology Lin Song (Hongta Liaoning Tobacco Co., Ltd. Yingkou Cigarette Factory, Yingkou 115002, Liaoning Province) air compressor system; centralized control technology; control scheme 1 air compressor control system ignorance control system is The automatic control system designed for the production and use requirements of Atlas compressors is intelligently controlled by centralized control system, and the operation and maintenance are convenient. The centralized control system realizes online control and monitoring optimization of compressor parameters, disturbance display and equipment such as dryers and filters to ensure long-term safe, economical, reasonable and efficient operation of the entire compressed air system. The control system can be fully integrated. Send it to the factory centralized control center to achieve unified management across the plant.

The four air compressors are connected to the ESBOX 8000 system by the centralized control system through the COMBOX-S/P module, and the Md-bus/P "O-us protocol" is transmitted to the ESC8000 system for display. Each device that enters the centralized control system includes, but is not limited to, the following information: run/stop; alarm; shutdown; start/stop; load/unload; time; pressure;

MDP and H wipe dry a few 2 sets: Cognac several devices can be connected to the centralized control system through the current * field line: run "Tiosk; fault; start" kiosk control.

Refrigeration unit (2 units in total): The refrigeration unit equipment can be connected to the centralized control system through field hard wiring: run/stop; fault; start/stop control.

Control: run/stop; fault; Qiting control and air compressor linkage control start and stop. :, the valve (a total of 2 sets): the valve can be connected to the centralized control system through the on-site magnetic coil line: run/stop; fault; Qiting control. According to the air compressor start-stop and linkage with this valve, the air compressor centralized control system randomly includes a pressure transmitter with a range of 01.6MPal, which is required to be installed on the air tank or air mother tube to monitor the system. The change of pressure can be set on the touch screen and the upper computer of the air compressor control cabinet. The user can set the target pressure range and the pressure of the air pressure gimmick system is within the set range. Once the system detects that the system pressure is lower than the set target pressure lower limit, it will automatically load the corresponding air compressor according to the set air compressor operating sequence; when the system pressure is higher than the set target pressure upper limit, the control system will automatically The corresponding air compressors are unloaded according to the set air compressor operating sequence. After the air compressor is unloaded for a long time, it will automatically stop to save energy consumption. The air compressor that is suitable for centralized control must ensure that it has the automatic restart function, that is, the air compressor will automatically stop after long-time unloading operation, and it will automatically start and force when the load signal is received, :, 4 control system sequential control (main Standby control J) The user presets the operating sequence for the air compressor on the centralized control system (up to 4 operating sequences, number 14), and the control system will operate according to the predetermined sequence switching conditions (time or event). 1 scoop switching, if the operator's intervention force is lower than the set target pressure lower limit, if the current order is 1, the system will load the corresponding air compressor in the order of 1, 2, 3, 4, 0 scoop; when the system pressure When the upper limit is set, the opposite order 4, 3, 2, 1 is unloaded or stopped, so that the pressure of the system will be controlled within the set range. If the order is 2, the system will unload the New Machines Page Order Switch (equivalent to the main and standby machine) in the reverse order according to the 2, 3, 1, 4 | port load in the reverse order. Switch, or manually switch.

Automatic fault switching function: When a machine fails, the next machine can be started in the pre-selection order.

Dryer control: When the air compressor centralized control system controls the dryer equipment, the dryer must have a remote start-stop operation disturbance state, and the fault disturbance state dry contact signal air compressor centralized control system can realize the remote manual start and stop control of the dryer. .

The air compressor centralized control system has two linkage control methods for the four dryers on site: 1) “Quantity of I alcohol control, 桉 set operation number and operation I crime sequence control fault handling: the control system detects The air compressor's fault trip will automatically retrieve the current white wolf line sequence. The comprehensive alarm and fault status of the nearest alternate air compressor air compressor will be reflected in real time to the local telecontrol interface and the upper view of the centralized control cabinet. On the interface.

Important parameters 篦 (such as target pressure, running sm; system township pressure tube display; air compressor operation / fault status display; air compressor main w visibility, exhaust pressure display,: D equipment unattended, Reduce operating and operating costs; 3 Apply air compressor centralized control system, air compressor station can realize automatic operation, no need to configure operators on site, which is about manpower running cost; system pressure is stable, save energy, can create economy for user warehouse U Benefits: When the centralized control system is not used, the loading and unloading sequence of the four air compressors is realized by setting a gradient on the loading/unloading pressure belt on the air compressor, so that the system pressure fluctuates greatly (large bandwidth) ), after using the centralized control system, the centralized control system centrally controls the loading and unloading of three air compressors according to the real-time pressure of the system mother pipe, which is a single-point pressure control, which can stabilize the system force in a relatively small pressure zone. Provide users with stable pressure and save energy: Introduction to music: Lin Song, born in the year, male, Yingkou, Liaoning, clothing science calendar, the current title is assistant engineer, the main research direction is equipment management,
