How To Determine The Service Life of A Second-hand Rotary Drilling Rig

In the field of engineering, the service life of second-hand rotary drilling RIGS is a key consideration when making a purchase. Accurately judging its lifespan can prevent low efficiency and potential safety hazards caused by equipment aging. The following introduces the key points of judgment for you from six aspects:

1. Check the date of manufacture of the equipment: The factory nameplate is the first reference. Be cautious of equipment that is over 8 years old and has no major repair records, as the wear of core components may have exceeded the critical value.

2. Check the engine condition: After starting, observe the color of the exhaust gas. Blue or black smoke may indicate wear of the piston rings or a turbocharger failure, which directly affects the power output.

3. Check the condition of the hydraulic system: If the hydraulic oil is turbid, oil is leaking from the pipelines or the operation is sluggish, it indicates that the seals are aging or the pump body is worn. The maintenance cost may increase exponentially with the years of use.

4. Evaluate the wear and tear of the drill bit and drill pipe: Deformation of the drill bit tooth seat, cracking of the drill pipe weld or peeling of the coating indicate that the structural strength of the equipment has significantly declined due to long-term high-load operation.

5. Analyze the authenticity of the construction hours: By comparing the ECU data with the readings on the dashboard, if the hours are abnormally low, there may be a meter adjustment behavior, and the actual wear and tear may be masked.

6. Request complete maintenance records: Equipment without major overhaul records is not necessarily in better condition; instead, it may age faster due to lack of maintenance. Replacement records of key components are the core evidence for life assessment.

Conclusion: To determine the service life of second-hand rotary drilling RIGS, it is necessary to combine "hard indicators" with "soft data" - paying attention not only to objective parameters such as the year of manufacture and working condition detection, but also to the analysis of maintenance history and usage intensity. It is recommended to entrust a professional institution to conduct a comprehensive assessment to avoid making decisions solely based on price or appearance. Only in this way can the procurement cost be reduced while ensuring construction safety and efficiency.
