LG Electric-Driven Stationary Air Compressor
Product Features
Our air compressor is built with a high-efficiency screw air end that delivers outstanding energy-saving performance. It adopts two-stage compression with interstage cooling, allowing the compression process to be closer to isothermal compression for higher working efficiency. With reasonable compression ratio allocation and optimized bearing design, the compressor operates with low noise, low vibration, and high reliability. Two-stage compression reduces the compression ratio of each stage, reduces internal leakage, improves volumetric efficiency, lowers bearing load, and effectively extends the service life of the screw air end.
The professional screw air end uses an exclusive rotor profile that provides stable and excellent performance for every model. Heavy-duty axial and radial bearings ensure a long service life under continuous working conditions. Triple shaft seals are used in key positions to completely prevent leakage. The wear-resistant shaft sleeve is processed by precision hardening and grinding, equipped with an O-type sealing ring, making maintenance more convenient and efficient. Each unit achieves world-class performance and efficiency, producing a large air displacement with a lower motor power.
The compressor is equipped with a full set of customized air volume control systems. Proportional valves accurately feed pressure signals to the servo cylinder and intake control valve. The intake control valve realizes 0–100% stepless adjustment to match air supply with actual air consumption, achieving excellent energy-saving effects. The thermostatic valve automatically controls the temperature of lubricating oil to keep its viscosity in the best condition, ensures the discharge temperature is above the pressure dew point, and prolongs the replacement cycle of lubricating oil. The minimum pressure valve maintains stable injection pressure for lubrication, reduces air flow in the oil-gas separator to improve separation efficiency, and also provides the function of a check valve.
The high-efficiency cooling system adopts a low-power, low-noise axial cooling fan for stable and efficient heat dissipation. With intake and exhaust muffler design, the compressor runs more quietly and maintains high stability in long-term operation.
