1. Frequency conversion speed regulation technology
Frequency conversion speed regulation technology is an effective energy saving method for air compressor. By installing the frequency converter, the running speed and output pressure of the air compressor can be flexibly adjusted according to the actual gas demand, thus realizing effective energy conservation. When the gas consumption is small, the air compressor can run at low speed to reduce energy consumption; When the gas consumption increases, the air compressor can quickly increase the rotating speed to meet the production demand. Practice shows that adopting frequency conversion speed regulation technology can significantly reduce the energy consumption of air compressor and improve economic benefits.
2. Application of high efficiency motor
Motor is the main energy consumption component of air compressor, and its efficiency directly affects the overall energy consumption of air compressor. Therefore, choosing high efficiency motor is one of the key measures to reduce the energy consumption of air compressor. High efficiency motor has higher operating efficiency and lower energy consumption, which can significantly reduce unnecessary energy waste while meeting production requirements. For example, the power consumption efficiency of Y-type step motor is 0 lower than that of General JO-type motor. 5%, while the average efficiency of YX motor is as high as 10%, which is 3% higher than JO motor [1].
3. Optimize the gas circuit system
Gas circuit system is an important part of air compressor, and its performance directly affects the energy consumption and efficiency of air compressor. By optimizing the gas circuit system, such as selecting air filter and oil & gas separator with less pressure loss, regularly cleaning the cooler and pipeline, selecting large diameter low pressure loss water pump power saving system intake valve and other components, it can significantly reduce the energy consumption of air compressor and improve the operation efficiency.
4. Manage leaks
Leakage is one of the important reasons for the high energy consumption of air compressor. By controlling leakage, such as checking and repairing leakage points of pneumatic tools, hoses, joints, valves and other components, the energy consumption and cost of air compressor can be significantly reduced. According to statistics, the average leakage of compressed air in the factory is as high as 20% ~ 30%, controlling leakage is one of the effective ways to reduce the energy consumption of air compressor.
