◆ 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.

◆ 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.
