Direct Driven Double Screw Air CompressorConfiguration CharacteristicsA precisely-made central bracket is used to keep the motor aligned permanently with the air end. A highly resilient coupling is adopted to make the compressor operate smoothly, and the elastomer is long in useful life. The discharge pipe is double-wall corrugated pipe, and the oil way uses a special high-pressure hose which is resistant to temperature up to 125℃.For the extremely high temperature conditions in some districts, the large-area plast heat exchanger and high-efficiency water cooler are used. High-quality direct driven elastic body can buffer and compensate for the imbalanced moment of operation.The elastomer is designed into an involute cambered surface, which effectively avoids stress concentration and improve the buffering effect of the elastomer to increase its bearing capacity.In addation, the high-quality materials ensure excellent durability for the elastomer and can better absorb the vibration arising from the rotation to remove noise.ReliabilitySince no wearing parts are used for the double screw air end, it can operate up to 40,000-80,000 hours under the condition of well maintenance and no failure.Technical parametersModelYD-ERCYD -ERCYD -ERCYD -ERCYD -ERCYD -ERCYD -ERCYD -ERCYD -ERCYD -ERC10SA15SA20SA25SA30SA30SW40SA40SW50SA50SWType of coolingair-coolingair-coolingair-coolingair-coolingair-coolingwater-coolingair-coolingwater-coolingair-coolingwater-coolingAir delivery/1.1/71.8/72.4/73.1/73.8/73.8/75.3/75.3/76.6/76.6/7working pressure1.0/81.65/82.2/82.9/83.6/83.6/85.0/85.0/86.2/86.2/8(m³/ bar)0.85/101.5/102.1/102.7/103.2/103.2/104.3/104.3/105.7/105.7/10　0.7/12.51.3/12.51.8/12.52.3/12.52.5/12.52.5/12.53.6/12.53.6/12.54.6/12.54.6/12.5Power (kw)7.5111518.5222230303737Voltage/powerAC   380/50(V/HZ)Start Method Y-△Noise db(A)72±5 Measure according to the international standard: GB/T4980-2003Content of oil discharge<3ppm3ppm
