Coping Strategies for Industrial Cooling Systems of Water Well Drilling Rigs in High Temperatures

In summer heat or tropical areas, water well drilling rig face tough cooling challenges. We need targeted measures to prevent overheating.

 

  1. Optimize cooling system parameters: Increase radiator area by 20-30% from standard. Use high-flow pumps and fast fans to boost cooling. Byvoorbeeld, a rig working at 40℃ enlarges radiators from 2㎡ to 2.5㎡. It raises fan speed by 10%, lifting cooling efficiency by 25%.
  2. Strengthen coolant management: Water-cooled systems use antifreeze (boiling point 108℃) to avoid high-temperature boiling. Hydraulic systems switch to high-temperature anti-wear oil (-20℃ to 100℃). This reduces viscosity loss. A rig in desert areas, after oil replacement, kept oil at 55℃, 10℃ lower than before.
  3. Add auxiliary cooling and adjust work rhythms: Install spray devices in front of radiators. Evaporation cuts inlet air temp by 5-8℃. Put heat shields on engines and hydraulics to reduce radiation. One site used sprays; the rig worked 6 hours non-stop without overheating alarms. Shorten work in midday heat (12-3 PM). Stop 10 minutes every 2 hours for cooling. Avoid direct sunlight with temporary shades.

 

These steps cut overheating faults in water well drilling rig by over 50%, ensuring work efficiency.
