Multifunctional Two Stage Screw Compressor For Metallurgy And Mining Industry





  • Variable frequency
  • Variable frequency air compressors can start steadily in the soft start mode, which could reduce power consumption at the start of the compressor.
  • Variable frequency air compressors set the minimum pressure of production equipment as the standard pressure. Rotation speed of variable frequency air compressors can fluctuate according to pressures of pipes, so as to guarantee constant pressure of pipes and reduce power consumption caused by pressure loss.
  • Power consumption of ordinary air compressors in idle load is only 45% of that in full load. Variable frequency air compressors are free from loading and unloading, so permanent magnet variable frequency air compressors consume no power at these two stages.
  • Improve operation efficiency


1. High quality of airend


  • The rotor adopts advanced high-efficiency molded lines, which ensures stability and high-efficiency;
  • It adopts two-stage independent compression, same pressure ratio, low speed design, thus enhancing more than 15% of air volume under the same power;
  • Guarantee of low compression ratio at every state, smaller host engine leakage, higher volume efficiency;
  • It adopts oil mist spray cooling at stage intervals, so as to make the entire compression process close to isothermal compression, thus improving the compression adiabatic efficiency;
  • The two segment rotors are directly driven by bevel wheel, so that each rotor obtain the best line speed, and the compression transfer efficiency is the highest;
  • The rotor and bearing have small load, the constant operation of host engine ensures long life;

2. Highly efficiency and energy-saving screw airend


The air end is connected with big rotator and is designed with low rotat-ing speed, and it contains two independent compression units. It is featured by high efficiency, low noise, low vibration, high reliability, low compression ratio in each stage, smaller leakage and high volume efficiency. Under the same power, two heads bear load while bearings bear small load with longer service life.


3. Highly efficient and energy-saving permanent magnetic motor


The airend is highly efficient and energy-saving permanent magnetic motor with protection level of IP55 which is elaborately selected according to requirement of application of air compressor, it reaches national grade-1 energy efficiency standard, both torque and load can meet special design standard so as to achieve optimization of motor efficiency and power factors under loading conditions. This optimized coefficient has about 5%-8% advantages when compared with efficiency of other motors.


4. Highly efficient and energy-saving filter system


Highly efficient oil-gas separator with special simplified design, aggregated separator core and oil return device, its service life is 6,000h. Oil filter is of low-pressure design with service life reaching as long as 4,OOOh, and high filtering precision protects bearing and screw rotator.

Air filter doesn’ t need to change air flow direction when doing filtering, instead, it directly runs through filtering medium, this reducing pressure loss, it is more energy-saving than traditional air filter with large filtering area, higher compactness and longer service life.


5. Highly efficient cooling system


It adopts highly efficient fin-type cooler with large heat exchange area, surplus of heat exchange being 30% and more optimal cooling effect, and it can normally operate under environmental temperature 45°C.


6. Energy-saving air inlet control system


New-type integrated inlet valve of professional design with large range of air inlet adjustment . It has valve regulation with small pressure loss, stable movement and long service life. Key part of inlet valve—magnetic valve uses internationally famous brand, which guarantees absolute operating safety and


7. Intelligent microcomputer control system


This system is of simple operation, it can realize Chinese/English and complex font switching with air filter/oil filter/oil fine separator/lubricating oil, it uses intelligent time monitoring and management, it even has remote monitoring function to be chosen by the user.


8. IOT PLC infinite extension module


Permanent magnet frequency characteristics


1. 24-hour warning sending of the system


The warning systems of maintenance and breakdown are triggered as soon as maintenances are needed or breakdowns happen.then the equipment management members and the mainrenance members of the distributors will be informed at the soonest time through the way of message or email,through which,both the secondary loss and the major breakdowns of the machinery can be avoided.



protection Subversion tradition Lead the future

  • The extremely efficient and synchronic motors
  • Its efficient turnning frequency with a broad range makes gaining much more energy-saving operation space possible.
  • With the same power, in contrast with the air displacement produced by the single-stage compressors,an extra 15% of air displacement will be produced by the two-stage compressors.
