- When the borehole is expanded 5 meters before the expansion, the ventilation department shall be notified to adjust the air volume, and the gas content of the expanded borehole section shall be checked to prevent the expansion of the borehole from affecting the ventilation system and the accumulation of gas in the borehole causing ventilation and gas accidents.
2. When drilling a pilot hole, arrange for someone to clean the slag at the orifice to prevent the slag from accumulating at the orifice, and it is strictly forbidden for metal debris to fall into the hole.
3. Strictly implement the operation sequence of "stop first, then stop water; first boil water, then start".
4. After the water well drilling tool is debugged, it is strictly prohibited to reverse the oil pump. When installing a new oil pump, motor, or replacing the oil pump or internal parts of the motor, the housing must be filled with hydraulic oil.
5. The components, joints and pipelines connected to the hydraulic system must be cleaned to prevent the entry of debris and damage to the hydraulic components.
6. Do a good job in the patrol inspection of the hydraulic system, and notify the driver of any leakage or other problems in the hydraulic system to stop the machine for handling.
7. It is strictly forbidden for the cooling device to leak water to the hydraulic system, causing the hydraulic oil and water to mix, and damaging the hydraulic components.
8. The oil pressure requirements for Water Well Drilling Tools: The oil motor of the main pump system is generally 8-20 MPa and the maximum is not more than 25 MPa. The auxiliary pump system is generally maintained at 6 to 15 MPa, and the maximum is not more than 22 MPa.
