AI Technical Summary
Existing water source drilling rigs are unable to combine impact crushing and cutting crushing of rock formations in drilling in hard formations, and cannot comprehensively judge the slag removal capacity and drill bit performance during the drilling process, resulting in low drilling efficiency, high safety risks and high production costs.
By intelligently controlling multiple parameters such as intake air pressure, reverse air pressure, mechanical drilling speed, and torque, the rotational speed, drilling pressure, and air pressure of the drilling components are adjusted to achieve synergy between impact crushing and cutting crushing, accurately monitor chip removal, and dynamically adjust the performance of the drilling tools to ensure high drilling efficiency.
It enables efficient rock breaking and rapid removal of cuttings during drilling in hard formations, reducing the risk of equipment overload, extending the service life of drill bits, and improving the economy and safety of drilling.
