Frequency inverter for Air Compressor

Air Compressor is a kind of machine which compresses the air to increase the air pressure or to transport air. Since it's always possible that the compressor works for long time with full load, it's necessary to determine the motor capacity according to the largest demand. Thus the design margin usually too large. Besides, the wearing of the bearing is very large, which causes more maintenance. Although both are started by decompression, the current is still very large when the air-compressor is started, which will affect the steady of the power system and the safety of other equipment. Because the dragging machine of the common air-compressor can't raise speed by itself, it's impossible to decrease the speed to fit for the power directly through changing pressure or flow. The machine can't allow to be started too frequently, thus the machine still needs to work without load, which wastes a lot of power.
Offloading and loading frequently causes the whole air network pressure changes very often, which can't keep the constant pressure and prolong the compressor's life. In some of the regulating mode (i.e. regulating valve), when the demand flow is small and because the machine's speed doesn't change, the decrease range of the machine power is small. All in all, if using frequency-regulating technology, when the demand flow decreased, decreasing the speed of the machine can reduce the working power of the machine a lot, which can save a lot of energy.
The regulating range of the air-compressor's pressure is large and less steady. One compressor will idle when not at peak time, which waste energy a lot. Especially during evening, the using amount is small, this situation often happens. Energy-wasting is serious.

Using Gozuk advanced vector control frequency inverter can supply larger torque when the machine runs at low speed and automatically compensate speed change of high-load running. Excellent dynamic, as well as the excellent over-loaded capacity can meet various needs in many fields.
Gozuk frequency inverter need very little maintenance cost. Compared with the traditional V/F control, vector inverter has the improved low-speed-running feature and the ability of regulating the speed under changeable load situation is also improved, gains higher torque for starting as well. This has significant advantage in the starting of series friction and inertia load. Just because of this feature, this control technology becomes the first choice of the customers.
Benefits of the transformation for Air-Compressor

2) Saving energy, decreasing the cost
3) Increasing the precision of pressure controlling
4) Prolonging the life of compressor
5) Decrease the noise of air-compressor
