Currently, there are many types of rotary drilling rigs available in my country, and their prices are generally quite high. To purchase a rotary drilling rig that meets the industry's needs in terms of both price and industry-specific requirements for market expansion, the following points should be considered when selecting a rotary drilling rig:#chinese drilling machine#
1. Select a model with suitable drilling capacity based on the type of pile foundation work being carried out;
2. For the same model from the same manufacturer, primarily compare three parameters: rated slewing torque of the power head, single-rope lifting force of the main winch, and machine weight. Choose the model with the highest values in all three;
3. Carefully analyze the performance-price ratio of the drilling rig.
4. Choose a drilling rig with good after-sales service whenever possible.
5. Understand the manufacturer's specifications, including the rated output torque of the drilling head, the rated working pressure of the hydraulic system, and the main safety factor-all crucial parameters for assessing the actual capabilities and reliability of the drilling rig.
After determining the model size, consider the following when purchasing a rotary drilling rig:
1. Drilling Torque
Select the drilling torque according to project requirements to ensure the rotary drilling rig can reliably operate in its high-energy zone. The drilling speed is closely related to the structure and parameters of the drill bit.#chinese drilling machine#
2. Drill Rod
The drill rod must transmit the full torque of the power head to the drill bit at the bottom of the hole, and also stably transmit the pressure of the pressurized hydraulic cylinder, the weight of the power head, and the weight of the drill rod to the drill bit tens of meters below. Therefore, when drilling into harder formations, the drill rod must simultaneously withstand high torque and heavy loads. If the drill rod does not meet these requirements, it is easily damaged.

3. Mast Adjustment Structure
Currently, there are two main types of adjustment structures for rotary drilling rigs: triangular and parallelogram-shaped, each with its own industry applications. On-site, considering installation, disassembly, and operation, the parallelogram-shaped mast adjustment structure is more practical.
4. Other Considerations
Rotary drilling rig power systems are reliable and have long trouble-free operating times. Generally, engines readily available domestically should be used. Hydraulic and electrical systems also require reliable performance and are readily available domestically.
