First, after completing the inspection of each air compressor in the compressed air supply system, you can start to analyze and optimize the working conditions of the air compressor station and the application of compressed air. Through analysis, you can know the energy-saving potential of the existing system and formulate measures for energy-saving optimization of the compressed air supply system.
The most important thing in this stage is whether the formulated measures are consistent with the actual requirements.
Only when the load operation time of the air compressor in the system is the longest, or the no-load operation time is as short as possible, can the energy-saving optimization of the system be achieved. In addition, it is necessary to reduce the leakage of compressed air as much as possible and reduce the working pressure of compressed air.
Because reducing the pressure by 0.1MPa is equivalent to energy saving of 6% to 8%. By taking measures, the load operation time can be as long as possible, the no-load operation time can be as short as possible, and the pressure can be constant at the lowest pressure level, that is, a better configuration of the air compressor station can be achieved.
The second is to use air compressors with adjustable speed and combine them with air compressors with load-no-load operation mode.
The advantage of this air compressor configuration method is that the compressors with basic load in the air compressor station cover the range of basic pressure requirements and will not make the air compressor station work in an uneconomical working range. If the required compressed air volume exceeds the basic load demand and there is a peak in the compressed air demand, the compressor with adjustable speed can cover some areas.
With this solution, the compressed air volume provided by the compressed air system can accurately meet the current actual needs, avoiding high-energy no-load operation, expensive unloading time and loss of compressed air during unloading, thereby achieving high energy saving, eliminating the peak load when the compressed air system starts, optimizing the pressure range, and achieving a constant working pressure.
The third is to adopt the compressor energy consumption control configuration method controlled by the upper level and related to energy consumption.
In this configuration, large-volume compressed air is generated by multiple load-no-load regulated compressors. At this time, the intelligent energy consumption control system controls the air compressor to start and stop according to the amount of compressed air required, and adjusts the pressure range of all air compressors according to the principle of energy saving.
