What are the main energy consumption of air compressors?

An air compressor is a machine that uses a motor to drive a host to compress air. It consumes a lot of energy during use. So do you know where the air compressor mainly consumes energy? Where can we start to save energy in air compressors?

1. Air compressor energy consumption

1. Control method: Since the air compressor will run for a long time at full load, it is best to determine the motor capacity according to the maximum demand when selecting the model. However, this will cause the air compressor system margin to be generally too large. Traditional air compressors use star-delta step-down starting, but when starting at power frequency, the current can still reach 2 to 3 times the rated current, causing a large impact and affecting the stability of the power grid. 2. Gas leakage: Only 10% of the electrical energy consumed by the air compressor is converted into compressed air, and the remaining 90% is converted into heat energy, but we often ignore this.

2. Air compressor energy saving

According to the operating characteristics of the air compressor, if the motor speed is reduced to a certain level, the air supply volume will decrease a little, but the energy consumption will be reduced a lot. This process is often realized through a permanent magnet frequency conversion controller. The frequency converter adjusts the gas flow by adjusting the speed of the motor, so that the output power of the motor is proportional to the flow demand, maintaining the high efficiency of the motor, high power factor, small reactive power loss, and obvious power saving effect.

3. Permanent magnet variable frequency air compressor

The Sollant permanent magnet variable frequency unit adopts a new design, and the high-efficiency permanent magnet motor and the high-efficiency host are perfectly matched. Through the advanced speed regulation and frequency conversion technology of the frequency converter, it can significantly reduce the customer’s cost of use and provide stable and reliable compressed air. The permanent magnet variable frequency model can adjust the operating speed of the air compressor according to the air consumption of the terminal, so that the power consumed by the air compressor is linearly proportional to the air volume generated, so as to achieve the purpose of stable pressure and energy saving, and can eliminate no-load operation Wasted power, stable terminal air pressure, smooth start, no impact.
