Common Causes and Solutions of Rotary Drilling Rig Failures

Rotary drilling rig is one of the commonly used engineering machinery in construction, especially suitable for drilling operations in foundation projects. However, due to the high frequency of use and high work intensity, rotary drilling rigs are prone to some malfunctions. This article will introduce the common causes and treatment measures of rotary drilling rig failures.

Fault 1: Steel cable breaks

Steel cable breakage is a common problem during the use of rotary drilling rigs. The reason may be that the steel cable used is worn or too old, or the drilling rig may be squeezed by excessive stress. For the treatment of broken steel ropes, the steel ropes need to be replaced first, and manual inspection can be carried out first to ensure that the quality of the replaced steel ropes meets the standards.

Fault 2:Rotary drilling rig turntable stuck

It is common for the turntable to get stuck during the operation of rotary drilling rigs. This situation is usually caused by the fact that the bearing where the turntable is located is not lubricated or has insufficient lubrication. It is necessary to check whether the lubrication system is operating normally and ensure that lubricating oil is added regularly during routine maintenance.

Fault 3: Oil leakage in hydraulic system

Oil leakage in the hydraulic system is caused by insufficient quality hydraulic oil flowing within the machine. The solution to this failure is to clean the hydraulic system and replace the hydraulic oil. Since the hydraulic system is one of the key parts in the operation of the entire rotary drilling rig, it must be checked regularly to ensure that the hydraulic system is always in good condition.

Fault 4: Drill pipe stuck in the soil

When a rotary drilling rig is performing drilling operations, it is also a common problem for the drill pipe to get stuck in the soil. This situation is usually caused by the construction worker failing to monitor the progress in time during the drilling process, causing the drill pipe to become stuck in the soil. When the drill pipe is stuck in the soil, you need to swing the drill pipe backward first and gently press it down to try to make it continue to move forward. If the situation is serious, it is necessary to change the drilling direction and drill again.

Fault 5: Engine broke down

Engine failure is also common during the use of rotary drilling rigs. This situation may be caused by reasons such as excessive service life, poor quality, or insufficient routine maintenance. The treatment method is to conduct a detailed inspection of the engine to ensure that the engine oil is used correctly, the filter is not used for too long, and the engine valve opening and closing, water, electricity and other systems are in normal condition.

Generally speaking, by sharing the common causes and solutions of rotary drilling rig failures, we hope to improve everyone's understanding and maintenance capabilities of rotary drilling rigs, and ensure that rotary drilling rigs can always maintain efficient, stable and safe operation during work.
