• Begin with "low speed, light pressure" drilling (≤1/3 rated value) until 10-20cm depth is achieved
• Monitor pressure gauges and drilling rig vibration continuously during operation
• Immediately stop operation for any pressure drops, severe shaking, or abnormal noises
• Never touch rotating components, stand directly below the rig, or modify equipment during operation
• Always stop machine, cut gas supply, and clean threads before adding drill rods

Scope of application (covering all scenarios)

1.Civil and agricultural: drinking water wells, farmland irrigation wells, ground source heat pump wells, suitable for soft soil, sand layers, and clay layers.
2.Engineering applications: construction site dewatering wells, foundation pit support holes, large-diameter pile holes, and reverse circulation for dealing with 3.quicksand and and pebble layers.
4.Geological exploration: hydrogeological survey, environmental monitoring wells, capable of drilling deep holes of 100-200 meters
5.Special working conditions: construction in urban areas (without damaging the road surface), hard rock fragmentation in hilly and mountainous areas (pneumatic drilling).

Key selection points (quickly matching customer needs)

1. According to depth and diameter: choose small positive and negative circulation for shallow wells (<50m); Select hydraulic power head+high flow mud pump/air compressor for deep wells (100-200m).
2. According to the stratum: normal circulation is used for soft soil/sand layers; Reverse circulation is used for clay/pebble layers; Pneumatic impact drilling is used for hard rock.
3. According to working conditions: low-noise rubber tracks are selected for urban construction; Choose diesel electric dual power for field operations to cope with inconvenient power supply scenarios.
4. Supporting requirements: Large diameter wells are equipped with pipe twisting machines; Deep water wells are equipped with high-pressure mud pumps to ensure slag discharge efficiency.
