GL120YG-A High Pressure Drill Rig
GL120YG-A High Air Pressure Drill Rig powered by diesel engine or electric motor to drive hydraulic system, which providing power for hydraulic motor walking, rotation, pushing and lifting, cylinder angle positioning, hydraulic winch etc.. It is multi-angle drilling, strong gradeability, floating adjustable parallel, fast drilling speed and flexible. It can save more than 30% energy compared with pneumatic drill. The drilling speed can be 20-35 m per hour with the rock rigidity f=6-18, especially suit for large gradient, frequent movement, Multi-angle work. It is mainly used for surface mining, stone works projects, conservancy and hydropower, road construction and solar panel working.
The fuel consumption at different drilling diameter and different air pressure:
| Medium Pressure Drilling（1.2~1.4Mpa) | High Pressure Drilling（2.0~2.5Mpa) | |||||||
| Drilling dia.(mm) | 115 | 140 | 165 | 300 (Solar pole) | 115 | 140 | 165 | 300 (Solar Pole) |
| Air consumption (m3/min) | 11 | 11 | 16 | 24 | 16 | 16 | 24 | 24 |
| Air compressor fuel consumption (L/h) | 25 | 25 | 28 | 35 | 28 | 28 | 35 | 35 |
| Drilling depth (m) | 30 | 30 | 30 | 10 | 30 | 30 | 30 | 10 |
| Drilling efficiency per hour (m/min) | 15~20 | 13~18 | 11~16 | 5 | 20~30 | 18~27 | 16~24 | 5 |
Different configurations to choose on the basis of actual working conditions:
| optional configuration | classify | watt level | performance feature | relative dominance | comparison |
| power | diesel engine | YC4D95Z-T21 | power margin, power flow strong | working and transitions easy, wide subject range | intolerant high or low temperature, wide noise, transitions high cost |
| electrical machine | 45KW | energy conservation | the most ability, low temperature resistant, low noise, low operation cost | working and transitions not easy, not widely subject range | |
| dusting method | dry dust removal | import high speed motor | rotary stream and filter element, without obvious dust | suit for all kinds of working condition and season, without affecting life of drill tool and drilling efficiency | higher cost, complex construction. |
| wet dust removal | no power consumption | the dust fall effect is adjustable according to working condition | low cost, simple construction, less failure | Unfit for all kinds of working condition and season, reduce affecting life of drill tool and drilling |
