China Two-Stage Screw Air Compressor - Energy-Efficient Solutions from Leading Suppliers and Factory
Air-end
Two-stage compression compared to single-stage compression, the two compression tends to the most provincial power of the isothermal compression,from the principle, the single-stage compression of the two compression energy saving 5~8%.
Won the award of Level 1 energy Efficiency Grade Certification. Compared with Level 2 Energy Efficiency GradeSave 10%-15% energy. Compared with Level 3 Energy Efficiency GradeSave 20%-30% energy.
- Adopt two-stage independent compression ;
- The pressure ratio is equal over both stages as well as having a lower compression speed, which helps improve volumetric efficiency;
- Oil mist spray cooling is used between the stages to make the entire compression process close to isothermal compression and improve the compression insulation efficiency；
- The two-stage rotors are directly driven by the bevel gear respectively, and the compression transmission efficiency is high；
- The large diameter and low speed of the rotors reduce stress on the bearings, thus lengthening their life span as well as any other components.
Controller
LCD HD touch monitor, PLC control ,Human menu interface design.
Can display multi line operation parameters, historical records.
Simple operation,inquiry, convenient maintenance.
Inverter
The inverter is the brain of the air compressor, and all operations of the air compressor are processed and regulated through the inverter, ensuring the safe and reliable operation of the air compressor system in all aspects. We typically use inverters from Megmeet, Inovance, and Zoncn, which are internationally renowned brands with stable and reliable quality and guaranteed after-sales service, providing customers with the best possible air compressor user experience.
Motor
The main motor is an IP55 high-efficiency energy-saving permanent magnet motor carefully selected according to the application of the air compressor. （other IP level available)
All meet the national energy efficiency standards, F-class insulation, B-class temperature rise, effectively prevent the entry of dust，SKF heavy-duty bearings ensure continuous trouble-free operation for a long time.
