1. Technological breakthrough: Two stage water spray screw technology
Zero pollution guarantee: using water lubrication instead of lubricating oil, compressed air oil content ≤ 0.01ppm, meeting FDA food grade standards (such as Zhengli Jinggong water lubrication models);
Energy Efficiency Disruption: Zhengli Precision's newly launched 200kW permanent magnet two-stage compression oil-free machine has a specific power of ≤ 5.2kW/(m ³/min), saving 35% energy compared to traditional models and meeting the national first level energy efficiency standard.
2. Analysis of key parameters
Pressure dew point: Precision manufacturing industry requires ≤ -70 ℃ (such as chip manufacturing), while conventional factories require ≥ -20 ℃;
• Volume flow error: The national standard allows for a ± 5% fluctuation, and a 10% margin should be reserved when selecting to cope with peak gas consumption;
Intelligent cloud control: ABB has deployed a cloud platform for Sinopec to adjust the gas production pressure in real time, avoiding 6% energy waste caused by 0.1MPa overpressure.
3. Application scenario upgrade
Medical aseptic workshop: using centrifugal oil-free machines (such as the 450kW maglev model of Yisheng Technology), with noise ≤ 65dB;
Distributed energy station: Kaishan's 7000Nm ³/h process machine is used for hydrogen compression, with exhaust pressure exceeding 25MPa
