Therefore, the screw rotor with six grooves compresses as many as 12 times per rotation.√ QuietnessWithout applying thrust load to the axis direction of the rotor, the force in the circumference direction rotates quietly with good balance. As a result, the load to the bearing is lightened, minimizing the generation of noise or vibration.√ DurabilityThe gate rotors are rotated following the rotation of the screw rotor along its gear. The water film formed on the screw rotor's gear and the free floating mechanism maintains the high efficiency for a long time (in case of water lubrication).√ High EfficiencySince the lubrication water is jetted in the compressing process, the compression is done smoothly under almost even temperature, realizing ideal, safe and highly efficient compression with slow rotation (in case of water lubrication).ComparisonWater Lubricated oil-free single screw air compressorDry oil-free double screw air compressorAir Discharge Tempabout 50ºCabout 180-200ºCClearance VolumeRotor has been used twice through one circulationNo clearance volume leftRotor has been used once through one circulationExisting clearance volumeAir DeliveryIdeal isothemal compression,air delivery volume5%-12% moreEnergy lost due to hot air dischargeEfficiencyNormally:59-6.4 kw/(m3/min)Normally:6.0-6.6 kw(m3/min)Air Quality100% oil-freeOil in the gear,high risk of air qualityAir PurityPurified by water,clean air after separationDirectly compressed then discharge,containing dust and oil stainStructure BalanceRadial and axial loads cancel each otherRadial load is not been balancedNoise and VibrationSimple structure,Low vibration and less noise,Normally:60-65 dB(A)High frequency noise due to screw grinding,Normally:64-78 dB(A)DurabilityRotation speed 3000r/min,theoretically zeao load,long lifetime of screw(30000h),star wheel(50000h)Rotation speed 18000r/min,high loads on crews,short lifetime of screw(8000-18000h)InstallationOnly a few spare parts,canbe installed and adjusted separatelyComplex construction,needs special technical support for installationMaintenanceOnly replaced air filter and water filter,easy maintenance and low costMany spare parts and less maintenance cycle,high costApplicationTechnical Solutions?Does the water corrode the air compressor system?Water lubricated compressor is desirable to use pure drinking water standards,parts and materials is conform to the international standard grades of 304 and 316 stainless steel,will never rust.?Does the water affect the service life of bearings?Uses a high-tech nanotechnology,customized silicon carbide bearing and ceramic bearing,lubrication with water directly,won't any problems?Will the efficiency of water lubrication oil free compressor go down?Technology is the only truly grasp the essence of a single screw manufacturing company in the world,inherited the Germany hundred processes and technologies,so the air end warranty for two years,the service life of up to ten years or more,a single screw air end efficiency does not decrease more than 5% after 6 years.?Does the water form scale?System uses pure water which is accord with driking water standards,water has been circulating in the system;and every 200hours total,the system will automatically change the water,make sure the water dows not increase the calcium content,and actively running a tempreature not higher than 50ºC,there is no risk of fouling.?Is the water content in water lubrication compressor air high?After air compression,the water content has reached saturation,the water content of the compressed air only related to the tempreature,there is no relationship with other,the temperature of the compressed air generated by water lubrication unit is not higher than 50ºC,so the water lubricated compressed air moisture than other types of compressors units.Sales ServiceProfessional online consultant to solve your question about compressor system.√ Free site design consultant, and energy saving solution to help you save operation cost.√ Negotiable technician available to service machinery overseas.√ online professional after-service until solve the problem.√ 1 year warranty after commissioning or 16 months against shipping date, it depends on which one come firstly for the wholemachine(except maintenance consumable).√ A sufficient number of spare parts are available, make sure the good after service.Certificateabout MikovsMikovs Compressor Founded in2011Main product:air compressors, air dryers and air filtersProfessional R&D team, acceptcustomizationorderStrong quality controlteam, quality is strictly controlledRFQQ1.
