220kw Rotary Energy Saving Two Stage Lubricated Air Compressor (KF220-7II)
The effective and reliable airend system of High Efficiency Air Compressors is achieved by integrative designing that use two separated compression elements with compact structure.
The reasonable linear velocity of first and second compression rotors of Two Stage AC Compressor is achieved by built-in master-slave gear unit inside the airend assembly.
The high reliability and stability for compressor achieved by using high precision "SKF" heavy-duty conical bearings that face-to-face arrangement and design life over 100000 hours, which were paired mounting in airend discharge end. 15 "SKF" heavy-duty bearings were used in each airend unit, which were importedfrom Sweden, for Industry Application Compressor.
Features of Adekom Two Stage Air Compressor
1.Low energy consumption
To ensure air is compressed with isobaric ratio in first stage and second stage compression and to reduce compression work and suction temperature for secondary stage compression, air discharged from first stage is cooled drastically by oil spread cooling in the coupling cavity between stages. Two Stage Rotary Compressor use two stage compression instead of one stage compression to achieve required pressure can achieve 10%~15% adiabatic efficiency and energy saving.
Two stage screw compression technology uses isobaric ratio principle to set the inter-stage pressure for the first and second stage compression, which not only reduces compression ratio for each stage of compression and air leakage, but also greatly improves volumetric efficiency and adiabatic efficiency. Use two stage compression to achieve required pressure can achieve 93%volumetric efficiency,improves compressor delivery capacity. While one stage compressionachievesmaximum 90%volumetric efficiency (90%).
Prevention of pressure loss and high energy consumption are achieved by adopting oil mist-spraying cooling method on inter-stage, this is specially designed for reducing unnecessary parts such as intercooler and associated piping.
2.Low maintenance costs
The compression ratio of each stage is reduced by using two stage compression technology, axial and radial forces exerted on rotors are greatly relieved, which improve the service life of the rotors and bearings dramatically. Special designed oil mist-spraying cooling method on inter-stage avoids unnecessary parts (e.g. intercooler and piping), and reduces associated maintenance cost, such as for the Pharmaceutical Industry Compressor.
