The invention discloses a compressed air control system and a compressed air control method based on an air demand. The compressed air control system comprises one or more air compressors, a system controller, a front end pressure sensor, a compressed air outlet pressure sensor, a flowmeter and a proportioning valve. The air compressors are provided with external communication interfaces or external digital quantity input-output interfaces for feedback and control of data communication or dry contact state of the controller. From the aspect of demand of an air terminal, the air supply pressureof a compressed air general pipe is controlled dynamically through the proportioning valve as the lowest guarantee pressure needed by the air terminal, and the operating quantity of the air compressors is controlled according to the actual flow of the compressed air, so that air consumption and generation of the compressed air system are balanced dynamically, and therefore, the operating efficiency of the compressed air system is improved and the energy waste is reduced.
Description
technical field [0001] The invention relates to an air compressor system control technology, in particular to a compressed air control system and method based on air demand. Background technique [0002] At present, factories generally have a supporting compressed air system to provide compressed air as one of the equipment power for the production workshop. The production process of compressed air is generally that the air is compressed by the air compressor, then passes through the post-processing equipment (dryer, cold dryer, filter, etc.) to remove water and oil, and then passes through the compressed air pipeline to the gas terminal. [0003] In order to reduce the number of starts of the motor and prolong the service life of the motor, the power frequency air compressor uses a pressure belt to control the loading and unloading of the unit, which causes a certain fluctuation in the pressure of the compressed air, and the pressure fluctuation higher than the minimum guar...
