High-efficiency Intelligent Variable-frequency Screw Air Compressor
Description
SUCCESS ENGINE VSD series (inverter driven compressor) and YC series (permanent magnetic variable frequency compressor) is a new-conception energy-saving product. By varying the speed of the drive motor in accordance to the change of the air capacity required, it regulates the actual power accordingly and thus saves the energy effectively. By adopting the electronic inverter system and the technology of supplying the exact air capacity required and precise pressure controlling, VSD air compressor not only directly reduces energy consumption by 30% but also brings many other benefits, such as stabilizing the network pressure, eliminating the peak current on starting, etc. VSD compressor serves as the best choice for the modern industrial and mining enterprises to save energy.
Variable Speed Drive Air Compressor (SEVSD7.5KW-315KW Series)
1. Power: 10-425HP, pressure: 0.7-1.3MPa.
2. Top compressor air end, variable frequency motor, and ABB/SUCCESS ENGINE frequency converter are adopted; Air consumption change is automatically tracked and the motor speed is adjusted correspondingly; Energy consumption is reduced by 30%.
3. Variable frequency motor: Protection class of IP55, insulation class of F, service factor SF=1.2.
4. The variable frequency starting greatly reduces the impact caused by instantaneous current on the grid, this effectively extending the service life of machine.
5. The adopted PLC intelligent control system supports control mode selection, operation status display, parameter presetting and fault history query.
6. There is a MODBUS485 interface reserved for remote monitoring.
7. Type of cooling: Air cooling or water cooling.
8. Product of different working voltage and frequency can be customized, 120V, 220V, 240V, 400V, 415V, 440V, 460V, 575V, 50Hz and 60Hz.
Performance features
1.Stable Pressure
The variable speed air compressor adopts PID for precision speed adjustment.Changes in the air amount of the system will be automatically tracked.The compressor will supply air at a constant pressure,which is the preset desired pressure plus or minus 0.1bar,to reduce power consumption.
2.Variable Flow Control
The ABB frequency converter adopted is able to adjust the rotation speed of the motor in real time according to the actual air compression.In case of high air consumption,the pressure remains unchanged,but the speed compensates automatically to meet the supply needs.When the air consumption is low,pressure is maintained constant and speed is automatically reduced to supply compressed air which is just enough.
3.No Current Impact during Starting
The air compressor is started via frequency converter.The maximum starting current is 1.2 times the rated current for power frequency start.Hence,our variable speed air compressor exerts little impact on the grid during starting.It enjoys reduced stress and consequently prolonged service life.
4.High Economical Efficiency
Throughout the operating life of the air compressor,energy costs account for most of all costs.However,by using s VSD,energy consumption is reduced by 30%.Therefore,the energy cost saved by a variable speed air compressor for three years is roughly equivalent to purchase price of the unit.
Main Components
Evaluation and Assessment of the saved energy
While electricity consumed by industrial air compressors accounts for a great part of a manufacturing facility’s total electricity bill, VSD air compressors can provide valuable energy saving for manufactures. However, an accurate assessment of the varying air capacity required before settling on the investment program is indispensable to getting a good return for the investment.
Stable Supply of Pressure
With the adoption of PID (proportional gain, international gain and differential gain), VSD air compressors can modulate the speed of the drive motor precisely. VSD series can also automatically track the change of the air volume, stabilize the pressure in the system and in turn reduce the electricity consumption.
Avoidance of Peak Current
Regards to VSD air compressor, peak current is avoided on starting the machine, so the damage to the power network and the whole mechanism is greatly reduced and the service life of the compressor is thus prolonged.
