Servo Inverter Screw Air Compressor

Features of AirHorse Servo Variable Speed Drive Screw Air Compressor
To determine whether an air compressor energy-saving,usually check “Specific
power”(input power ÷ Displacement per minute),That is ,under the same
displacement. The lower input power,the better specific power. AirHorse
Servo-inverter compressor is saving users’valuable energy by a significant
reduction in the specific power. Start small impact
Smooth soft start,Maximum starting current is within 1.6 times the rated
current,Compare to Frequency start which is usually maximum startingCurrent is 6
times.AirHorse serve inverter compressor decreased much Starting inrush
current,Reducing the share of transformer.make sure motor safety.
Air supply pressure stable
Improve the output frequency to Improve working efficiency.
Energy
Variable speed,Greatly improved the speed accuracy.
Can adaptive grid voltage
Over –modulation technique of inverter,it Sufficient torque output When the AC
voltage is slightly lower,Driving motor working well;If the AC voltage is
higher,It will not lead to a high voltage output of the motor.
Low noise
The inverter running according to air flow,there is no energy loss,the lower
operation frequency of motor,the smaller noise of rotation.Because inverter to
adjust the motor speed mode,without repeatedly loading,unloading,Reduce the
noise generated by the frequent loading and unloading,Continued
loading,Reducing the noise produced by unstable Barometric pressure. A small
amount of equipment maintenance
A small inverter starting current,Less than 2 times of the rated
current,without repeated loading and unloading,Inverter compressor
automatically adjust motor speed according to air consumption,The lower
operating time,the longer life of equipment,the smaller maintenance work.
Its easy to control under internet,automatic the production control.
Compared to V/F inverter technology,its higher efficient of low-frequency
operation,ster dynamic response,(So that the air compressor less load
fluctuations)More accurate speed control(Greatly enhance the accuracy of the
air comsumption). Saving power by factor compensation
Reactive power not only Increased line loss,but also heating Equipment,the
more important is leads to lower power factory by reducing active power
grid.Large amount of reactive power consumed in the circuit,Low equipment
efficiency,Wasted Our AirHorse servo inverter machine,As the role of the
inverter internal filter capacitor,Thereby reducing the reactive power
loss,increasing the active grid.
Inler screw host

Large rotors ,low rpm,long life span,High efficiency,low noise,low
vibration,high reliability,Bearings life over 100,00 hours, Little leakage
triangle ,low power/airflow ratio,Less

Plate-fin Cooler
The radiator adopts the high efficiency plate fin structure,heat
exchange,lubricating oil adopt double flow,compressed air adopt single
process,heat balance margin is big,can adapt to worse running condition.

Air oil separator
Large margin design,multi-stage separation Long service life the oil content of
less than 3ppm Ensuring excellent air supply Made from imported glass fabric
Less pollution,Less maintenance.

Multifunctional touch screen
High resolution display,the panel is more clear,rational layout,air compressor
operation date checking more convenient.The ARM processor,mass storage,make the
Communication more efficient.

The unit separation design
Screw machine master for split design, convenient head seal replacement and
motor

The comparison between servo
inverter compressor , inverter
compressor and screw air
compressor without inverter.
A 90kw, Energy Efficiency (0.8Mpa international specific power is 7.3, ?0.7MPA
The motor energy efficiency remains unchanged, the specific power is 6.8) ( Max
pressure is 0.8Mpa, unloading pressure 0.7Mpa) air-cooled compressor Customer’s
actual air consumption: (Assumption) input power 90KW ÷7.3KW/M3×70%=8.63Nm3
AirHorse servo inverter screw air compressor: According to the actual
displacement demand, Constant pressure 0.70Mpa, Required power = displacement
8.63Nm3*specific power 6.8KW/M3=58.68KW Normal inverter compressor: The average
actual input power per minute: (Load power: 90KW*70%=63kw)+(unloading
power:90KW*30%*0.45=12.1KW)=75.1KW screw air compressor without inverter : The
average actual input Compare inverter compressor, the servo ?inverter compressor
saving more energy power: 75.1kw-58.68kw=16.4kw /hour The servo inverter
compressor is 20% higher effectiveness than Inverter compressor. Compare screw
air compressor without inverter, the servo ?inverter compressor saving more
energy power: 99KW -58.68KW = 40.3KW The servo inverter compressor is 40% higher
effectiveness than screw air compressor without inverter
If each machine is working 14 hours a day, working 240 days a year, energy power
cost USD 0.19 /degree Compare screw compressor without inverter, the servo
inverter compressor saving energy power cost: 40.3*14*240*USD 0.19= USD 25727.00
