8.4~11.7m³/min Two Stage Screw Air Compressor 65KW 8.4~11.7m³/min Air Cooling
◆ The relationship between the three power, work pressure and
volume flow rate
When the power is unchanged, the volume flow rate and working
pressure will change correspondingly when the rotational speed
changes. For example, a 22KW air compressor is manufactured with a
working pressure of 7bar, and the rotational speed is calculated
according to the technical curve of the main engine of the air
compressor. The exhaust volume is 3.8 m3/min. When the working
pressure is 8bar, the rotational speed must be determined. It must
be reduced (otherwise the drive motor will be overloaded), at this
time, the exhaust volume is 3.6 m3/min; because the speed is
reduced, the exhaust is reduced accordingly, and so on.
The selection of power is based on the condition that the working
pressure and volume flow are satisfied, and the power supply
capacity can meet the use power of the matched driving motor.
Therefore, the selection of air compressor steps are: first
determine the working pressure, then determine the corresponding
volume flow, and finally the power supply capacity.
| Air intake status | ≤Ambient temperature intake pressure 1.013bar(A) | Voltage(V) Frequency(Hz) | 380V50Hz |
| Start-ups | Y-△ | Noise dB(A) | 72±5dB |
| Oil Content | 1~3ppm | Outlet Air Temperature | ambient temperature+8℃ |
◆ Consider the combination of gas fields and conditions.
If the use of air space is narrow (marine, automotive), it should
be vertical; if there is a long-distance change in the use of air
(more than 500 meters), it should consider mobile; if the use of
electricity can’t be used, it should choose diesel engine driving;
if there is no running water in the use of occasions, it must
choose air-cooled.
Users often have a wrong idea about air-cooled and water-cooled
cooling modes. They think that water-cooled is good. Air-cooled
modes account for more than 90% of small air compressors at home
and abroad. This is because air-cooled is simple in design and no
water source is needed in use.
There are four fatal shortcomings of water-cooled air compressor:
it must have complete upper and lower water system with large
investment; water-cooled cooler has short life; it is easy to
freeze the cylinder in winter in the north; it will waste a lot of
water in normal operation.

⊙ description
1. Asymmetric profile with 5-lobe male rotors and 6 flute female rotors.
2. Reduced differential pressure between flutes helps decrease backflow, thus, increases adiabatic efficiency by 10~12% and energy saving by 25% as compared with the 4 to 6 profile design.
3. Casing and bearing seats are integral parts and machined in the same sequence to achieve high precision and to minimize clearances.
4. A bearing design life of 50,000 hours can beassured by the specially designed short rotors with minimum vibration and bending stress.
5. Rotors revolve at low speed; thus, low noise level can be guaranteed.
6. A wide pressure range from 4 to 15kg/cm2G to suit various needs.
