Centralized control mode of air compressor
Adopting frequency conversion speed regulation method to reduce the shaft power output of the air compressor motor. Before the renovation, when the pressure of the air compressor reaches the set pressure, it will automatically unload; After the renovation, the air compressor does not unload, but reduces the gas production during the compressor by reducing the speed to maintain the pressure required by the gas network. There are two places where energy can be saved:
Reduce the electrical energy consumption caused by the sudden change process of the compressor from unloading state to loading state.
The operating frequency of the motor is reduced to below the power frequency, resulting in a decrease in the output power of the motor shaft. Both of the above methods have reduced the energy consumption of the air compressor to varying degrees during operation. However, the fact that the air compressor generates such a large amount of heat during operation that it dissipates into the air in vain has not received widespread attention from users for a long time. This cannot be said to be a great regret.
Centralized control method
Adopt centralized control mode for multiple air compressors. Automatically control the number of air compressors based on gas usage. Prior to the renovation, the number of air compressors opened was fixed.
(1) If the air consumption is further reduced, the high-performance air compressor will automatically shut down. In the case of (1), the air compressor still consumes electrical energy even during unloading. After the renovation, the corresponding number of air compressors can be stopped, reducing the number of operating units and undoubtedly saving electricity.
(2) When the gas consumption is reduced to a certain amount, the air compressor reduces the gas production by reducing the loading time.
Based on the gas consumption situation, the number of air compressors can be reasonably controlled to balance the running time of the air compressor. The system has self-learning ability, continuously optimizes the operating mode, and real-time detects the exhaust pressure, temperature, and operating status of the air compressor. It can manually control the air compressor, alarm for abnormal operation of the air compressor, record, store, and query the operating situation of the air compressor, and generate daily, monthly, and annual reports.
The auxiliary control function of the air compressor stabilizes the overall pressure of the compressed air system by adjusting the operation of a single air compressor, while recording relevant data and generating reports.
