Air compressor centralized control system and control method thereof

Abstract

The invention discloses an air compressor centralized control system and a control method thereof. The air compressor centralized control system comprises an air compressor unit, a controller module, an air compression collecting and combining pipeline, a timing drainage assembly, a nitrogen generation control assembly, an adsorption dryer assembly and an air compressor monitoring module. According to the air compressor centralized control system and the control method thereof, real-time data, read by a flow meter, of the real-time compressed air usage amount are collected and judged through the controller module, when the real-time data numerical value is lower than the lower limit of the numerical value interval set in a PLC module, the PLC module unloads part of the running air compressors and the adsorption dryers, so that the output amount of compressed air is matched with the usage amount, centralized control is realized, the usage amount is balanced according to terminal requirements, the effect of saving energy is achieved, and when a real-time data numerical value is higher than the upper limit of a numerical value interval set in the PLC module, the PLC module starts part of standby air compressors and adsorption dryers. The output of the compressed air can meet the use requirement in time, the situations that a production line is interrupted and operation is affected are prevented, sequential control over the main machine and the standby machine is achieved, and production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of air compression, in particular to an air compressor centralized control system and a control method thereof. Background technique [0002] People's daily life is inseparable from air. The oxygen component in the air is one of the indispensable gases for human survival. In addition to being very important to human life, air is also widely used in industry. Due to the compressibility of air In nature, people use air compressors to compress air to form compressed air as an important power source. Compressed air as a power source has clear and transparent, convenient transportation, no special harmful properties, no fire danger, not afraid of overload, can be used in many Advantages of working in unfavorable environments. [0003] The manufacture of compressed air is a very tedious and rigorous work. In the process of compressed air manufacturing, a series of equipment such as air compressors, suction dryers...

AI Technical Summary

Problems solved by technology

[0004] 1. Manual opening and manual closing need to communicate with the tank farm, small packaging, and refining personnel, and match the number of equipment according to the number of production lines opened on site and the process sections to meet the actual needs. Management is very troublesome

[0005] 2. Unable to make an emergency. When the equipment suddenly encounters a failure, it is necessary to wait for the user to report that the air pressure is insufficient before knowing the failure, which will affect the production efficiency.

[0006] 3. It is necessary to arrange experienced personnel for real-time security management, which is a waste of manpower
