Energy-Saving Frequency Conversion Control Cabinet for Air Compressors - China Suppliers & Factory
Product Description
Interlocking & Frequency Control
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. The cabinet has local and remote control functions, and each unit operates independently in local mode.
Remote Mode Operation
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.
The cabinet connects to multiple air compressors to enable frequency conversion linkage control. It adjusts unit frequency and maintains constant pressure based on the real-time pressure of the pipe network.
It supports both local and remote control modes. In local mode, each compressor unit operates independently. In remote mode, the system coordinates multiple units automatically.
Under remote mode, the frequency conversion control unit accelerates operation. If it reaches the highest frequency and still does not meet the set pressure, the cabinet will start the next compressor unit after a set delay.
If the pressure is higher than the set value, the frequency conversion unit decelerates. If the pressure remains high, the cabinet will trigger a delayed shutdown of the next active compressor unit.
This function prevents total gas supply failure if the interlocking cabinet itself malfunctions. It allows operators to manually start the machine on-site once all display devices have fully stopped, ensuring uninterrupted factory operations.
