Do all variable-frequency air compressors need to be equipped with an inverter?

Do all variable-frequency air compressors need to be equipped with an inverter?

  The frequency conversion air compressor, as the name suggests, is based on an ordinary power frequency air compressor, equipped with a frequency converter, and uses frequency converter vector control. In other words, during the operation of the screw air compressor, if the air consumption fluctuates, and the terminal uses more air from time to time, sometimes less, then the inverter of the variable frequency air compressor will play a role to adjust the motor speed , To adjust the motor current, so as to achieve the purpose of saving electricity, and finally realize how much compressed air is used to produce as much compressed air.


    The country advocates energy saving and emission reduction, which has led to air compressor sales staff to hype up the many benefits of variable frequency air compressors, making factories and enterprises that need to buy screw air compressors believe that in order to respond to the call of the country, it seems that they must buy variable frequency air compressors. Ah, so no matter what, regardless of the company's specific production gas situation, if you think that the frequency conversion air compressor is good, you must buy a frequency conversion air compressor. In fact, sometimes this is not necessary.


    For example, if the production air consumption fluctuates little and is very stable, then you can calculate the air consumption as a little bit. If you buy an ordinary power frequency air compressor, the load time can reach more than 80% of the total running time, so you don’t need to buy it at all. The frequency conversion air compressor is used. Because of this air consumption, even the frequency conversion air compressor basically has no effect.


    Of course, if the production air fluctuates greatly, then it is recommended to buy frequency conversion, after all, the frequency conversion air compressor can still save electricity at this time. Whether to buy a variable frequency air compressor or not depends on the actual situation of air consumption. There is no need to follow the trend. There are two sides to everything. The simpler the thing, the more reliable it is. One more component means one more. The failure rate, whether to buy or not, you have to choose by yourself. Having said so much, let's use it as a reference.
