The water well drilling rig DTH hammer requires these safety steps:
-
Air pressure safety:
Compressor pressure must not exceed the hammer’s rating (
usually ≤2.0MPa)
to prevent part bursts.
-
Operation protection: Operators wear earplugs (110dB noise) and goggles to stop flying rock chips.
-
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.
