What is the reason for the high power consumption of air compressors?
According to research, the power consumption of the air compressor system can account for 15%~35% of the total power consumption of gas-using enterprises, and the energy consumption cost will account for about three-quarters of the whole life cycle cost of the air compressor. Therefore, the energy efficiency improvement of air compressors is particularly important for enterprises to save energy and reduce carbon emissions, so what is the reason for the high power consumption of air compressors?
01
Improper selection of air compressor
The production needs of enterprises are different, and the requirements for air compressors are also different. However, when purchasing air compressors, some enterprises overemphasize the one-time investment, performance indicators and energy consumption indicators of air compressor equipment, and ignore the accurate evaluation of their own air consumption characteristics, resulting in improper equipment selection, such as excessive exhaust pressure and exhaust air volume, which is inconsistent with actual use, resulting in large margins, reducing equipment operation efficiency and waste of resources.
02
High energy consumption for unloading
When the air compressor equipment is running under load, the equipment begins to generate a large inrush current, which not only poses a threat to the safe and stable operation of the power grid, but also causes energy waste. When the air compressor equipment is no-load, the compressor motor is still running, and the equipment is running no-load. For the air compressor under the traditional adjustment mode, the energy consumption of the air compressor in the operating state is more than 20% of the energy consumption in the full load operation state of the equipment, and some air compressors can consume up to 40% of the energy consumption in no-load operation, and the energy consumption accounts for 9%~18% of the total energy consumption, which is a serious waste of electric energy resources.
03
Leaking pipes
Compressed gas leakage is a major hidden danger in air compressor stations. The working environment of air compressor station equipment is complex, and the equipment maintenance workload is large. The air compressor station pipe network has problems such as holes, aging or loose seals. If not fixed in time, problems will arise. Compressed gas leaks in the pipeline network have intensified, increasing the energy efficiency loss of air compressor stations. According to statistics, the leakage of compressed gas in air compressor stations accounts for about 20%~25% of the total output of compressed gas.
04
Waste heat is wasted
According to statistics, the electrical energy consumed by the compressed air of the air compressor is only 10% of the total electricity consumption, and the remaining 90% of the electrical energy consumption is converted into thermal energy. Due to the temperature requirements of the equipment, the mixed steam of oil and gas generated by the high heat generated by the compressed air will be discharged into the atmosphere as waste heat through the cooling system of the air compressor. It can be seen that the waste of waste heat of the air compressor is also one of the reasons for the high energy consumption of the air compressor station.
