Energy-Saving Frequency Conversion Control System for Air Compressors - China Suppliers & Factory Solutions
Product Description
Energy-saving control cabinet is connected with multiple air compressors for energy-saving control.
Frequency Conversion Linkage
The interlocking cabinet is a frequency conversion linkage device designed for air compressors. According to the pressure of the pipe network, the unit frequency conversion, constant pressure and linkage control can be realized. The interlocking cabinet can realize any and only one frequency conversion of the unit, and can freely switch the frequency conversion after the equipment stops.
Dual Control Modes
The cabinet has local and remote control functions, and each unit operates independently in local mode.
Remote Operation Logic
In the case of remote mode and remote mode operation, the pipe network pressure is lower than the set value of the interlocking cabinet, and the frequency conversion control unit accelerates operation. When the operation reaches the highest frequency and does not reach the set value, the interlocking cabinet delays the start of the next unit. On the contrary, the pipe network pressure is higher than the set value of the interlocking cabinet, and the frequency conversion control unit decelerates operation. Cabinet delay to stop the next unit.
Critical Operational Requirement
Due to the characteristics of the factory, the equipment can not be shut down. If the equipment can not be turned on and normal gas supply is caused by a major failure of the interconnect cabinet itself, the consequences are very serious.
Disaster Recovery Casting Function
To avoid this major problem at the beginning of the design of the interconnect cabinet, the disaster recovery casting function of the interconnect cabinet was added in the design. When the interconnect cabinet fails and the power frequency conversion cannot be selected and the machine cannot be started, the disaster recovery casting function of the interconnect cabinet can be started manually on the side of the machine when ensuring that all the display devices of the machine have stopped. Eliminate the worries of the failure of the joint control cabinet.
Frequently Asked Questions
What is the primary function of the energy-saving control cabinet?
The energy-saving control cabinet connects with multiple air compressors to perform unified energy-saving control, optimizing overall system operation.
How does the interlocking cabinet maintain constant pressure in the system?
It monitors the pressure of the pipe network to realize unit frequency conversion, constant pressure, and linkage control. It can run any single unit in frequency conversion mode and switch settings freely once the equipment is stopped.
What control modes are available for the interlocking cabinet?
The cabinet features both local and remote control modes. When switched to local mode, each compressor unit operates completely independently.
How does the remote mode control the startup and shutdown of units?
When network pressure falls below the set value, the frequency conversion unit accelerates; if it reaches max frequency without meeting target pressure, the system delays and starts the next unit. If pressure is higher than the set value, it decelerates and delays stopping the next unit.
What is the disaster recovery casting function?
It is a safety feature designed to prevent total system shutdown. If the interconnect cabinet fails and units cannot start normally, this function can be manually activated on the side of the machine (after ensuring all display devices have stopped) to restore the gas supply.
