Funcionamiento
During compression, lubrication water is injected into the compression chamber and bearings via the machine's own pressure differential. Water forms a water film between the rotor, star wheel, and casing, combining lubrication + sealing + heat absorption into one. Graphite bearings at both ends of the star wheel are directly water-lubricated. Every 200 hours the system automatically changes water. Main body operating temperature ≤50°C, with no scale accumulation risk.
