-
Less overheating downtime: A faulty system once caused 20-minute stops hourly—daily work <6 hours. Repaired, it ran 10 hours, lifting efficiency by 60%.
-
Stable power output: Cooling keeps engines at rated power. High temps drop power 2-3% per 10℃. Good cooling maintains 2m/h drilling; poor cooling slows to 1.5m/h.
-
Longer part life: Cooling reduces wear on bits and hydraulics. Cool systems extend seals to 6 月份; poor cooling cuts to 2 月份.
