Drilling Process Guidelines

Measurement: Regularly measure drilling depth (every 10m or when changing drill bits) and check gearbox components for overheating or abnormal sounds.

Water Supply: When using clean water drilling, ensure proper water flow before commencing operation and maintain adequate volume to prolong pump service life.

The pneumatic drilling machine utilizes high-pressure air as its power source, making it particularly effective for water intake projects in mountainous rock strata and various industrial drilling applications.
