How much do you know about rotary drilling rigs? Many people believe that rotary drilling rigs can drill larger diameters and deeper holes than traditional circulating drilling rigs, but this is a misconception. Do you know how many types of rotary drilling rigs there are and in which fields they are used? Today, Northern Foundation Leasing, a rotary drilling rig manufacturer, will discuss the characteristics of rotary drilling rigs and the precautions for purchasing them.#high performance drill#
Generally, rotary drilling rigs are suitable for drilling depths of 50-60 meters, with hole diameters of less than 2 meters, and most within 1.8 meters. In contrast, domestically produced reverse circulation drilling rigs can drill to depths of hundreds of meters, with hole diameters of up to 3 meters. Rotary drilling rigs can hardly achieve this, which is determined by the rig's structure. Rotary drilling rigs rely on telescopic drill rods for soil extraction. As the hole depth increases, a longer drill rod is necessary, which inevitably increases the drill rod's weight. This increases the overall equipment cost due to considerations for machine balance. Furthermore, if the drilling depth is too great, the drilling time inside the hole will be significantly less than the auxiliary time for lifting the drill and unloading soil, resulting in a substantial reduction in work efficiency. Although rotary drilling rigs do not have an advantage in drilling depth and diameter compared to circulating drilling rigs, they have significant advantages in terms of work efficiency, environmental protection, relocation, and especially adaptability to geological formations. These characteristics can precisely solve common problems in foundation construction.#high performance drill#
Important Considerations When Purchasing a Rotary Drilling Rig#high performance drill#
Currently, there are many types of rotary drilling rigs on the Chinese market, and their prices are relatively high. To purchase a model with ideal performance and price that suits your market development needs,
the following points should be considered when selecting a model:
① Choose a model with appropriate drilling capacity based on the pile foundation field your company is constructing;
② For products of the same level from different manufacturers, focus on comparing three parameters: rated swing torque of the power head, single-rope lifting force of the main winch, and machine weight. Choose a model with higher values in all three;
③ Carefully analyze the performance-price ratio of the drilling rig;
④ Choose manufacturers with good after-sales service whenever possible;
⑤ Understand the manufacturer's rated output torque of the power head, rated working pressure of the hydraulic system, and safety factor of the main winch-all important factors for assessing the actual capacity and reliability of the drilling rig.
Through the above introduction, we hope you have gained a better understanding of the characteristics of rotary drilling rigs and the important considerations when purchasing them.#high performance drill#
