When operating a rotary drilling rig, many beginners are puzzled as to why experienced workers seldom use high speeds. In fact, there are quite a few tricks hidden behind this. Now let's talk to you about the six key reasons why experienced workers are reluctant to use high rotational speeds.
1. Protecting the drill bit: High rotational speed will cause the drill bit to rub violently against soil and rocks, intensifying wear and significantly shortening its lifespan. To save costs and enhance the durability of the drill bit, experienced masters naturally won't easily use high rotational speeds.
2. Avoid hole collapse: If the rotational speed is too high, the soil around the hole wall will be greatly disturbed, which can easily cause it to lose stability and lead to hole collapse. The experienced master is well aware of the trouble caused by hole collapse, so he prefers a low rotational speed to ensure the quality of the hole formation.
3. Precise control: At low rotational speeds, the operator has more precise control over the drilling rig and can better adjust the drilling direction and depth. High rotational speed is prone to loss of control, affecting the construction accuracy.
4. Reduce energy consumption: High rotational speed means that the engine operates under high load, and fuel consumption rises sharply. From an economic perspective, the experienced master believes that using a low rotational speed is more energy-efficient and can reduce construction costs.
5. Reduce vibration: Excessively high rotational speed can cause severe vibration of the drilling rig, not only affecting the service life of the equipment but also potentially leaving the operators exhausted. Low rotational speed can make the construction more stable.
6. Adaptability to working conditions: Different geological conditions require different drilling strategies. Under most working conditions, a low rotational speed combined with an appropriate torque can actually complete tasks more efficiently. A high rotational speed is not omnipotent.
In summary, the veteran rotary drilling rig operators do not use high rotational speeds, taking into account multiple factors such as equipment wear and tear, construction quality, and cost control. High rotational speed may seem efficient, but in reality, it has many hidden dangers and significant drawbacks. According to different working conditions, reasonably selecting the rotational speed is the correct way to achieve efficient operation of rotary drilling RIGS.
