For Beginners Buying Second-hand Rotary Drilling RIGS, First Understand These 5 Basic Terms

For beginners, when purchasing a second-hand rotary drilling rig, mastering some basic terms can help them understand the equipment's condition more clearly and avoid communication barriers. The following five basic terms deserve special attention:

1. Hole diameter: It refers to the diameter of the hole drilled by the rotary drilling rig during operation, which directly affects the load-bearing capacity of the pile. Different projects have different requirements for the diameter of boreholes, and the selection should be based on actual needs.

2. Maximum drilling depth: This refers to the maximum vertical depth that the drilling rig can drill, which is an important indicator for measuring the operational capacity of the equipment. When making a purchase, the required depth for the project should be taken into consideration.

3. Engine power: The magnitude of the power output by the engine determines the operational efficiency and load capacity of the drilling rig. Insufficient power may lead to a slow drilling speed and make it difficult to cope with hard strata.

4. Hydraulic system: An important component of the rotary drilling rig, it controls the rotation, lifting and lowering of the drill pipe and other actions. Its performance directly affects the stability and smoothness of the equipment operation.

5. Number of drill pipe sections: Drill pipes are composed of multiple sections. The more sections there are, the greater the depth of the borehole that can be extended. At the same time, the material and wear condition of the drill pipe also need to be inspected with emphasis.

By understanding these basic terms, beginners can more specifically inquire about and inspect the equipment when purchasing second-hand rotary drilling RIGS, determine whether it meets the engineering requirements, thereby reducing purchase risks and improving the rationality of transactions.
