Abstract

The invention discloses an air compressor energy saving control method, device and system. The method comprises the steps that after an air compressor loads, air storage pressure of a forecast volume air storage tank and current air consumption of an air pipe network are acquired in real time, wherein an air inlet of the forecast volume air storage tank is connected with an air output port of the air compressor, and an air outlet of the forecast volume air storage tank is connected to an air using place through the air pipe network; the sum of the unloading time and the stop time which are needed after the air compressor unloads is determined according to the volume of the forecast volume air storage tank, a preset loading and unloading pressure difference and the current air consumption, wherein the preset loading and unloading pressure difference is a difference between preset unloading pressure and preset loading pressure; the unloading time and the stop time which are needed after the air compressor unloads are set according to the sum of the unloading time and the stop time, wherein the stop time is longer than 0. Accordingly, the energy saving effect of the fixed-frequency air compressor is improved at low cost.

Description

technical field [0001] The invention relates to the technical field of air compressor control, in particular to an air compressor energy-saving control method, device and system. Background technique [0002] Among the many energy sources used, compressed air is one of the most popular energy sources after electricity. Industry, mining, engineering, medical and even agriculture have increasingly wide applications, especially in industry, where the amount of use is extremely considerable. In view of the fact that compressed air has been widely used in all walks of life, under the premise of large-scale and automatic factories, the use of compressed air is increasing day by day. While the air compressor is compressing air, it also consumes a lot of electric energy. In the current industry, there are many factories using air compressors with thousands of horsepower or even tens of thousands of horsepower. How to use compressed air and air compressors reasonably? How to improv...
