Noise Control for Water Well Drilling Rig Cooling Systems

News 148 Views
A water well drilling rig cooling system—fans and pumps—makes 85-95 dB noise. Controlling it improves work conditions and meets environmental protection standards.

 

  1. Low-noise fan designs: Use axial fans (10 dB quieter than centrifugal types). Curved blades cut air turbulence. A rig’s low-noise fan runs at 75 dB, 15 dB less than traditional ones.
  2. Fan speed management: Adjust speed via temperature to avoid constant high speed. Below 85℃, a rig’s fan runs at 1000r/min (70 dB); high temps hit 2000r/min (80 dB). This cuts noise by 20-30% at low loads.
  3. Sound insulation and water path tweaks: Add sound shields (sound-absorbing cotton + sound insulation plates) around radiators. Vibration pads between fans and rigs reduce noise. One rig dropped from 90 to 78 dB, fitting residential rules. Water pump mufflers and flexible pipes cut flow noise by 10 dB.

These techs let water well drilling rig work near cities and homes, expanding their use.
