The Rules for Judging The Service Life of Second-hand Rotary Drilling RIGS

In the trading market of rotary drilling RIGS, second-hand equipment has attracted much attention due to its price advantage, and judging its service life is the key to selection. The following introduces the rules for judging the service life of second-hand rotary drilling RIGS.

1. Degree of wear of core components: The wear of core components such as engines and hydraulic pumps directly affects their lifespan. Check if there are any abnormal noises or oil leaks during the operation of the components. If the wear is severe and the repair cost is high, the service life will be significantly shortened.

2. Working hours record: Working hours are an important reference. Generally, the design life of equipment is approximately 20,000 hours. If it has approached or exceeded this value, even if it is well maintained, the remaining lifespan still needs to be carefully evaluated.

3. Completeness of maintenance records: Complete maintenance records can reflect the maintenance status of the equipment. Equipment that is regularly and properly maintained has slower component wear and tear and a relatively longer lifespan. Improper maintenance may hide potential problems and shorten the service life.

4. Rust and deformation of structural components: Inspect structural components such as drill pipes and masts. Severe rust or deformation can affect the overall strength. Such damage is difficult to be completely repaired and will significantly reduce the safe service life of the equipment.

5. Hydraulic system status: The hydraulic system is the key to power transmission of the equipment. Check whether the pipelines are aged and whether the seals are good. Frequent failures of the hydraulic system can lead to a decline in the operational efficiency of the equipment and indirectly shorten its service life.

6. Market reputation and brand factors: Second-hand rotary drilling RIGS from well-known brands, due to their mature manufacturing processes, have a more guaranteed lifespan under the same usage conditions. Brands with a poor reputation may have more malfunctions in the later stage and a relatively shorter service life.

In conclusion, determining the service life of a second-hand rotary drilling rig requires a comprehensive consideration of multiple factors. Core components, working hours, maintenance conditions, etc. are directly related to the equipment status. The conditions of structural parts and hydraulic systems affect safety and efficiency. Brand reputation also has certain reference value. When making a purchase, a comprehensive inspection is necessary to more accurately estimate its remaining service life and avoid unnecessary losses.
