Synergy Between Industrial Cooling and Hydraulic Systems in Water Well Drilling Rig

News 179 Views
In a water well drilling rig, the industrial cooling and hydraulic systems are closely linked. Their teamwork ensures stable operation and affects performance.

 

  1. Precise control of hydraulic oil cooling: Hydraulic oil needs stable temps of 30-50℃. Cooling systems use thermostatic valves to adjust cooling. Below 40℃, the valve shuts the radiator; above 45℃, it opens wider as temps rise. A rig with a proportional valve controls oil temp to ±2℃, avoiding element damage.
  2. Dynamic balance of heat load: Drilling load changes with geology, affecting heat output. Modern rigs use variable-speed fans. They run fast under heavy loads, slow or stop when light. This balances cooling and energy use. One smart rig’s fan saves 20% energy this way.
  3. Avoid over-cooling’s impact: In cold, over-cooling drops oil below 20℃, thickening it. Then cooling systems cut off heat dissipation —stop fans, bypass radiators. A rig bypasses cooling for 3 minutes in winter startup. It waits till oil hits 30℃, saving energy.

 

Good synergy needs precise controls. A water well drilling rig once had ±10℃ oil swings due to mismatch. Better matching reduced faults.
