D31 Energy-saving Renovation Plan For Air Compressors

An air compressor is a device that uses a motor to compress gas in a compression chamber and make the compressed gas have a certain pressure. It has a wide range of uses and can be used in various industries such as metallurgy, machinery manufacturing, mining, electric power, textile, petrochemical and so on. Air compressors account for 15% of the power consumption of large industrial equipment (fans, pumps, boilers, air compressors, etc.). After investigation, most air compressors have the following shortcomings: (1) When the output pressure is greater than a certain value, the load relief valve is automatically opened to make the asynchronous motor idle, which is a serious waste of energy. (2) The asynchronous motor is easy to start and stop frequently, which affects the service life of the motor...
