Description

High efficiency and energy saving double stage air end

First stage compression unit and the second stage compression unit are integrated in one air end driven directly by the helical gear, the optimal linear speed for each stage.

After the first stage compression, constant pressure compression by intensify spread oil cooling, reduce the second stage compression suction temperature, ensure that the second stage compression unit is close to isothermal compression.

Compression ratio reasonable distribution, optimized bearing design, second stage compression reduces the compression ratio of each stage, reduces internal leakage, improves the volume efficiency, reduces the bearing load, and improves the life of the air end.

In the same power, double stage compression energy saving is 15% more than the single stage compression.

                                 

The latest generation of efficient XA series rotor type line

Latest generation of XA series bilateral asymmetric optimization of rotor type line, male and female rotor 6/5 tooth number ratio.

“XA” series rotor type line, using SKF Cylinder and Angle contact ball high efficient bearings, bearing lifetime more than 100,000 hours.

big rotor, low speed, high precision, high efficiency, low noise, low vibration, high reliability, long lifetime design , adhering to the “high efficiency, energy saving, reliable, durable” manufacturing philosophy

Finite element assisted optimization design

Deeply analyze the reasons for the double stage compression energy saving

According to the working principle of screw compressor, isothermal compression process is the most economical.

The figure below shows the indicator diagram of the overall compression process. The curve 1-2′-3′ is the isothermal compression process, and the area of 6-1-3′-4 is the indicator work of isothermal compression.

Curve 1-2-3 “is the normal single stage compression process, and the area 6-1-3”-4 is the indicator work of normal single stage compression.

The curve 1-2-2′-3′ is the AUGUST double stage compression process, and the area of 6-1-2-2 ‘-3-4 the indicator work of AUGUST double stage compression.

From here you can see that the isothermal compression process ‘6-1-3-4 area is smallest (minimum indicated work), but in actual can’t achieve isothermal compression,while AUGUST double stage compression more energy saving than normal single stage commission .

High precision filtration separation system

1μm precision air filter, 10 μm precision oil filter,

large capacity design standard to ensure the compressor Long-term efficient and safe operation.

oil content≤3ppm,which provides you with a cleaner air source.

High safety control valve system

high quality inlet control valve, Large caliber, small resistance, precision casting

Reliable check valve, low fluid resistance, good sealing, quick closure

High quality minimum pressure valve, low pressure loss, open and close safety and reliability

temperature control valve prompt response, to avoid the condensed water

The fluoro rubber with O ring , the invisible place gives you the visible safety

Reliable cooling system

Large heat dissipation area design, avoid to high temperature stop.

Axial flow cooling fan, large air volume, Suction structure, heat evenly.

2 fan design, determine the number of starting fans according to the discharge temperature.

Unique cooling flow field with low noise.

Mixed flow system temperature control valve

Between first and second air end Inject cooling oil, in order to ensure the interstage compressed air temperature is always above the dew point temperature, using patent design of mixed flow system temperature control valve ,achieves the good interstage cooling and prevent the formation of liquid water, avoid corrosion and system oil emulsion problems
