The present invention provides an air compressor compression work optimization control method, device, equipment and storage medium. The method includes: the controller according to the primary intake air temperature, the primary exhaust pressure, the The first-stage compression multi-process index, the cooling medium inflow temperature, the second-stage intake pressure and the preset total compression ratio determine the first-stage compression ratio corresponding to the first-stage frequency conversion compressor unit; the controller according to The primary compression ratio and the preset value of the secondary exhaust pressure determine the target value of the primary exhaust pressure; the controller optimizes the compression work of the primary variable frequency compressor unit according to the target value of the primary exhaust pressure and / or, the controller optimizes the compression work of the two-stage frequency conversion compressor unit according to the preset value of the two-stage exhaust pressure; through the present invention, the optimal primary compression ratio and secondary compression ratio can be allocated Ratio, realize the optimal control of the compression power of the two-stage frequency conversion screw air compressor.
Description
technical field [0001] The present application relates to the field of two-stage frequency conversion screw air compressors, in particular to an air compressor compression work optimization control method, device, equipment and storage medium. Background technique [0002] Most screw air compressors are twin-screw air compressors, which are divided into two series: single-stage compression and two-stage compression. Because the compression of each stage of the two-stage compressor is smaller than that of the single-stage compressor, the internal leakage of the compressed gas is low, and the gas production is generally larger than that of the single-stage compressor. [0003] At present, there is a trend in the domestic market that two-stage compression screw air compressors will gradually replace single-stage compressors. [0004] In the current two-stage compression screw head, the two-stage screw is driven by gears, so the speed ratio of the two-stage screw is fixed; in a...
