Safety Tips for DTH Hammers in Water Well Drilling Rigs

ニュース 56 Views
The water well drilling rig DTH hammer requires these safety steps:

 

  1. Air pressure safety: Compressor pressure must not exceed the hammer’s rating (usually ≤2.0MPa) to prevent part bursts.
  2. Operation protection: Operators wear earplugs (110dB noise) and goggles to stop flying rock chips.
  3. Shutdown checks: Turn off the compressor and release pipe pressure before repairs to avoid sudden air-operated movement.

A jobsite didn’t release residual pressure. When disassembling the hammer, the piston popped out, damaging the water well drilling rig—no injuries though.
