What is the relationship between the drilling torque and the drill bit promjer a horizontal directional drill?

Tu je obično a certain odnos između the bušenje okretni moment i bušilica bit promjer a vodoravno usmjereno bušilica. Općenito speaking, the larger the drill bit promjer, the drilling torque needs to increase u skladu s tim.
To je jer the increase in the drill bit promjer will olovo to an increase in the cutting area, time increasing the resistance tiling the drilling process. In order to overcome these resistances, the drill rig needs to provide a greater torque to drive the drill bit to rotirati.
Međutim, the specific relationship will also be affected by other factors, such as formation conditions, the power and performance of the drill rig, the type and structure of the drill tool, etc. In practical applications, it necessary to make comprehensive considerations and selections based on the specific engineering conditions.
At the same time, in order to ensure the smooth progress of the drilling process and the drilling effect, it is also necessary to reasonly select the drill bit type, the drilling parametri, and perform appropriate drilling process control.
