Enterprises tend to consider air compressors when selecting super pipelines, which are slightly larger than the actual demand, between 25% and 30%. This will make the air compressor always in low load state in actual operation, close the air inlet, and reduce the operation efficiency.

The super pipeline ordinary screw air compressor is in constant speed operation state, and the actual gas demand is constantly changing. When the enterprise reduces the gas consumption, the air compressor unit can only be adjusted by completely or partially closing the air intake. In this case, the air compressor is often in the air transport state, and part of the load is running, and the full load is running alternately, resulting in a large amount of power waste. Therefore, How to solve the energy-saving problem of screw air compressor has become the research direction of many air compressor manufacturers.

When the installation flow rate of the air compressor pipeline is large, the pipe diameter is small, but the pressure drop value increases. Therefore, when the flow rate is large, the pipeline infrastructure investment can be saved, but the operation energy consumption cost of power equipment such as pumps and compressors increases. In addition, if the flow rate is too large, there may be some other unfavorable factors. Therefore, the pipe diameter shall be determined based on comprehensive consideration of construction investment, operation cost and other technical factors.

The variable frequency screw air compressor changes the running speed of the main machine of the air compressor by changing the power frequency, and then changes the exhaust volume of the air compressor. The super pipeline variable-frequency screw air compressor changes the screw air compressor by adjusting the operating frequency of the main motor of the air compressor.
