Intelligent group control energy-saving system for air compressors

Abstract

The invention discloses an intelligent group control energy-saving system for air compressors, which performs multi-stage, multi-link, and combined air utilization of air compressors, and is aimed at the air supply network management, air pumping system, air storage system, and air utilization system of multiple air compressors. The four links adopt the intelligent group control method to optimize the centralized and unified group efficiency, and the power saving rate can reach 20%-60%. The advanced flow control technology is used to detect the network management pressure and automatically adjust the air supply flow to reduce the consumption of the pipe network. ARM (32-bit) + DSP (16-bit) dual-CPU intelligent control system is adopted to realize vector flow control and greatly reduce the starting current of the compressor motor, avoiding the impact of the starting current on the motor and the motor when the air compressor motor is started for the second time. In case of damage to the contactor, the mutual air consumption of each air compressor can be automatically adjusted according to different air consumption conditions, and high and low pressure mixed air use, combined air use, balanced air use, and stable air use can be performed to maximize reasonable air supply save energy.

Description

technical field [0001] The invention relates to an air compressor intelligent control technology, in particular to an air compressor intelligent group control energy-saving system. Background technique [0002] At present, the usual operation mode of many air compressors is: generally adopt the pressure switch ON / OFF type fully open and fully closed control, use the upper and lower limit pressure detection of the cylinder to start and stop the motor, or install a clutch to achieve the desired constant pressure control, when the air pressure When the air compressor is at the lower limit of pressure, the motor runs at full load to achieve the purpose of air supply. When the air compressor reaches the upper pressure limit set by unloading, the motor enters unloading operation, and the excess air volume is discharged through the overflow valve. In addition, in order to meet the maximum production demand , when choosing the air compressor configuration, always choose the highest ...

[0002] At present, the usual operation mode of many air compressors is: generally adopt the pressure switch ON / OFF type full-open and full-close control, use the upper and lower limit pressure detection of the cylinder to start and stop the motor, or install a clutch to achieve the desired constant pressure control, when the air pressure When the air compressor is at the lower limit of pressure, the motor runs at full load to achieve the purpose of air supply. When the air compressor reaches the upper pressure limit set by unloading, the motor enters into unloading operation, and the excess air is discharged through the overflow valve. In addition, in order to meet the maximum production demand , when choosing the configuration of the air compressor, always choose the configuration with the highest air volume. The air consumption of the configuration is far greater than the actual air consumption. Not only is the air supply always fluctuating between the upper and lower limits, but most of the time it is not at full load It is operated under certain conditions, so the power consumption is huge, and there is obvious room for energy saving
