Is The Greater The Torque of The Power Head of The Rotary Drilling Rig, The Better

Among the many performance indexes of rotary drilling rig, the power head torque is a key parameter, which directly affects the drilling ability of drilling rig. Many people will think that the greater the power head torque, the more powerful the rig, the better the operation effect. But is this really the case? Now, let's dig a little deeper.

1. Application condition consideration: In hard rock formation, high torque power head can effectively break rock and achieve efficient drilling. However, in the soft soil layer, excessive torque is not only unnecessary, but also leads to fast drilling, and it is difficult to control the drilling quality.

2. Equipment loss problem: the power head torque is too large, which will make the drill transmission system, drill pipe and other components bear greater stress. Long-term use, easy to cause component wear, shorten the service life of the equipment, increase maintenance costs.

3. Energy consumption analysis: Generating high torque requires strong power support, which means that the engine needs to output more power and consume more fuel or electricity. In the long run, energy costs have risen sharply.

4. The difficulty of operation increases: the power head with excessive torque has higher technical requirements for the operator during operation. Once the control is not proper, it may cause problems such as drilling deviation and equipment shaking, affecting the construction safety and quality.

5. Equipment cost increase: In order to match the high torque demand, rotary drilling RIGS need to be equipped with larger and more complex power systems and transmissions. This has led to a significant increase in equipment procurement costs and greater capital investment.

6. Adaptation of supporting parts: The torque of the power head is increased, requiring the drilling pipe, drill bit and other supporting parts to be upgraded. If not matched, even if the power head torque is large, it can not play a full role, and even affect the overall performance.

Conclusion: The greater the torque of the power head of rotary drilling rig is not the better. When selecting rotary drilling rig and power head torque parameters, it is necessary to consider construction conditions, equipment loss, energy cost, operation difficulty and other factors. Only by reasonably matching the torque and actual demand, can the rotary drilling rig play the best performance and achieve efficient, economic and safe construction.
