TUBE, CYLINDER

137 876 08 TUBE, CYLINDER A cylinder tube is the foundational part of any hydraulic or pneumatic cylinder, providing the enclosed space where the piston operates. In an underground drilling rig, these cylinders are essential for many functions, from the powerful impact mechanism of the drifter to the precise positioning of the boom and the forceful advance of the feed system. The tube's smooth inner surface is crucial for the piston's movement and for maintaining the seals that prevent fluid or air leakage. It's designed to withstand significant internal pressures and external forces encountered during drilling operations.

The integrity of the cylinder tube directly impacts the overall performance and reliability of the equipment. Any damage, such as scoring, ovality, or cracks, can lead to internal leakage past the piston seals, reducing the cylinder's effective force and speed. External leaks are also a common symptom, indicating a breach in the tube's structure or a seal failure due to an imperfect surface. If a cylinder tube fails completely, it can result in a sudden loss of function for a critical system, potentially halting drilling operations and creating safety hazards on the mine site.

Common signs of a failing cylinder tube include visible fluid leaks, a noticeable drop in cylinder power or speed, or erratic movement. If the cylinder is part of the drifter, a damaged tube might lead to a significant loss of impact energy. Regular visual inspections can help identify external damage or leaks early. Once a cylinder tube is compromised, it generally requires replacement to restore the cylinder's full functionality and prevent further damage to other internal components. Attempting repairs on a severely damaged tube is often not cost-effective or reliable for critical mining applications.
