CYLINDER TUBE ASSEMBLY

551 663 43 CYLINDER TUBE ASSEMBLY A cylinder tube assembly forms the core of many hydraulic actuators on an underground drilling rig. It provides the sealed chamber where the piston travels, translating hydraulic fluid pressure into the linear mechanical force required for various functions. Depending on its application, it might be found in the feed system, pushing the drifter along the feed beam, or within the boom's hydraulic cylinders, enabling precise positioning of the drill string.

The integrity of the cylinder tube is crucial for safe and efficient drilling operations. Any internal scoring or external damage can compromise the seals, leading to hydraulic fluid leaks and a significant loss of power. A weakened or damaged tube can also result in uncontrolled movement of the boom or feed, posing a safety risk to personnel. When the cylinder cannot generate its full intended force or speed, the overall drilling penetration rate and accuracy are directly impacted, reducing productivity.

Common symptoms of a failing cylinder tube include visible oil leaks around the rod or barrel, slow or jerky cylinder movement, and a noticeable reduction in the force it can generate. External dents or deep scratches on the tube surface are clear indicators of damage. Regular visual inspections for external damage and checking for consistent cylinder operation are important. If significant wear, scoring, or damage is detected, replacing the cylinder tube assembly is essential to restore full functionality and prevent further damage to other hydraulic components.
