Do you know the inverter air compressor, how to realize the air compressor frequency conversion, and how to realize the energy saving of the inverter air compressor? Next, Youteng will take you to explore the knowledge of the inverter air compressor.

The Meaning of Air Compressor Frequency Conversion

Frequency conversion is to change the power supply frequency of the motor. Frequency conversion is abbreviated as VSD (Variable Speed Drive), which means variable speed drive. Air compressor frequency conversion can bring many benefits, it can reduce the starting current of the motor, reduce the impact on the user's power grid, automatically adjust the load to reduce power consumption, reduce losses, and prolong the service life of the equipment.

How to Realize Air Compressor Frequency Conversion

The frequency conversion technology is to rectify and filter the power frequency alternating current through the rectifier circuit into a stable direct current, and then convert it into an alternating current with adjustable frequency (generally up to 400Hz) through the inverter circuit, and finally output it to the variable frequency motor. The output frequency of the inverter (VSD) is proportional to the motor speed. Taking a 4-pole motor as an example, when the output frequency is 20Hz, the motor speed is 600rpm, the output frequency is 50Hz, and the motor speed is 1500rpm. Combined with the air compressor, when the gas consumption is large in normal working conditions, the motor input frequency is high and the rotation speed is high, and the gas production is high; when the gas consumption is small at noon, the motor input frequency is low and the rotation speed is low, and the gas production is small.

How to Realize Energy Saving of Inverter Air Compressor

Usually users will consider the maximum production conditions when choosing the installed capacity of the air compressor. However, the actual operating conditions only reach 60%-80% of the maximum gas consumption, or even lower. The traditional fixed-speed air compressor adopts the loading and unloading control technology. In order to not stop when the gas consumption is not large, the number of starts and stops of the motor is reduced by unloading operation. In the unloading state, the motor idling does not generate compressed air, and the power consumed at this time is called. Unloading power is actually a waste of energy. However, it is different after the air compressor adopts frequency conversion control. The frequency conversion air compressor will automatically adjust the motor speed according to the actual air demand of production to realize the air volume adjustment. When the air consumption decreases, the air compressor will automatically reduce the speed to reduce the Power consumption; it is a major advantage of frequency conversion to realize the constant matching between the air compressor gas production and the customer's gas consumption demand, and no unloading loss.

It is worth noting that inverter air compressor is not energy efficient under all operating conditions. When running at full load or close to full load, the energy-saving effect of the inverter is not so obvious. If the user's air consumption is very stable and has almost no change, it is more appropriate to choose a high-efficiency fixed-speed air compressor. It can be seen that only the appropriate selection can save energy.
