SUCCESS ENGINE Screw Air Compressor 15-90kW VSD Series

For the operation characteristics of air compressor and the actual situation of the user's manufacturing process, SUCCESS ENGINE has developed this high efficiency inverter which is dedicated for air compressor. The inverter was built into the compressor unit and fully compliant with the current electromagnetic compatibility standard (The voltage range: 380-500V, frequency range: 50-60Hz),the use of PID can adjust the speed accurately, tracking gas consumption changes automatically, that can ensure the power consumption of the compressor matches the actual power required by the compressed air, and achieve the best performance value without energy waste!

Energy saving overview of frequency conversion

Ⅰ.Stable Pressure
With inverter, the variable frequency screw air compressor can adjust speed regulation, and through the controller or the PID regulator it can start slowly. For occasions where air consumption fluctuates greatly, VSD air compressor can adjust quickly and transfer the compressed air with stable pressure, and dont waste energy.

Ⅱ.Control of variable air flow
Power frequency driven air compressor can only work at one exhaust, variable frequency air compressor can work in a relatively wide range of exhaust. The inverter is based on the actual air consumption to adjust the motor speed and to control the amount of exhaust, so that the power consumption of the air compressor can match the actual power required by the compressed air;
When the needs of air are low, the air compressor can be automatically dormant, so that the energy loss will greatly reduce.
Optimized control strategy can further improve energy saving efficiency.
 
Ⅲ.The voltage adaptability of AC power supply is better 
As the inverter adopts over modulation technology, it can output enough torque when the AC power supply voltage is slightly lower, and drive the motor work only according to the actual torque required; when the voltage is slightly higher, it will not lead to the output voltage to the motor is high;
For self-generating occasions, variable frequency drive will show its advantages more powerful;
According to the characteristics of the motor VF (VSD air compressor in the energy-saving state are working below 50HZ), for the grid of low voltage, the effect is obvious.
 
Ⅳ.Start without shock
As the frequency converter itself covers the function of soft start, the starting current is within 1.2 times of the rated current, compared with power frequency starting-generally 6 times more than the rated current, the starting shock is very small. Therefore, it will not be fined by the concerned authorities for the starting current is too large;

Ⅴ.Energy Saving Case
An ordinary air compressor of 55KW(According to the characteristics of the machine set work pressure, unloading pressure is 8bar,loading pressure is 6bar), the average air production is only 70% of the rated exhaust capacity, run 5,000 hours a year, industrial electricity costs 1.1 yuan / kwh. Compared with VSD air compressor, the ordinary compressor will produce two losses:1, no-load loss; 2, differential pressure loss.
1.   No load loss = 30% of the unloading time × no-load current loss (45% × 55 kW / h) × 5000 hours / year × 1.1 yuan / kWh = 40837 yuan / year;
Formula:0.3 ×0.45×55×5000) ×1.1= 40837.
2.  Differential pressure loss 70% of the loading time x the loss due to the pressure difference is higher than 2bar(kg) (14%×55 kW / h×5000 hours / year×1.1 yuan / degrees) = 29645 yuan / year;
Formula:0.7×(0.14×55×5000) × 1.1= 29645.

Case description:
When the air consumption varies greatly, compared with ordinary frequency units unit can be energy-saving 40837+29645=70482 yuan / year.
When the air consumption changes in the case of large, VSD air compressor can save 40837 +29645 = 70,482 yuan / year than ordinary compressor.
