Description

technical field [0001] The invention relates to a monitoring system for an industrial air compressor station, in particular to an on-site monitoring and evaluation system for the energy efficiency of an industrial air compressor station. Background technique [0002] Industrial air compressor stations have important and extensive applications in the industrial field. At present, most industrial air compressor stations are composed of multiple box-mounted oil-injected screw air compressors. The operating energy consumption of screw air compressors accounts for about 5% of the total electricity consumption in the country. The operating efficiency of screw air compressors is generally low. The correct evaluation of the energy efficiency of air compressors and efficient operation are urgent tasks. [0003] At present, industrial air compressor station is one of the main energy-consuming equipment of the enterprise, and its energy efficiency monitoring has attracted extensive att...

AI Technical Summary

Problems solved by technology

The heat generated by the motor, oil and gas barrel and other heat dissipation equipment in the box-mounted air compressor box will increase the intake temperature of the compressor; Throttling loss will occur. After the air enters the box, it is basically in a disorganized flow state, and the intake flow loss further increases; the increase in intake temperature and the decrease in intake pressure will directly lead to a decrease in intake air volume and an increase in compression work

[0012] According to statistics, the leakage of industrial compressed air systems often accounts for 20%-30% of the system's gas production. While causing energy waste, the pressure drop of the compression system caused by leakage will make pneumatic tools work and drive inefficiently. The more frequent operation of the equipment will inevitably lead to an increase in the running time of the compressor and a shortening of the service life of the compressor

The common leakage phenomenon of compressed air system is mainly caused by the lack of effective monitoring
