The cooling system of screw air compressors serves as the “temperature control core” for stable equipment operation. Its function is to promptly dissipate heat generated during compression, ensuring oil temperature and discharge temperature remain within safe limits (typically oil temperature ≤85°C, discharge temperature ≤100°C). Cooling system failure can lead to increased energy consumption and degraded lubrication at best, while at worst causing high-temperature shutdowns and shortening the host unit's lifespan. Therefore, scientific maintenance is essential for users:
