GLAND

758382 GLAND A GLAND plays a vital role in the hydraulic cylinders that power various functions on a rock drill, such as the feed system, boom positioning, or even within the drifter itself. Essentially, it's a housing that holds the rod seal and wiper seal in place at the end of a cylinder. Its primary job is to keep high-pressure hydraulic fluid contained within the cylinder while also preventing dirt, dust, and moisture from entering the system as the cylinder rod extends and retracts. This protection is crucial for the longevity and efficient operation of the entire hydraulic circuit.

When a GLAND functions correctly, it ensures that the hydraulic system maintains its intended pressure, directly contributing to consistent drilling power and precise control of the machine's movements. A leaking GLAND, however, can lead to a significant loss of hydraulic pressure, which might manifest as reduced penetration rates, slower boom articulation, or even an inability to hold position. Beyond performance issues, uncontrolled hydraulic leaks create slippery conditions, posing a safety risk for personnel working around the drill rig. It also allows abrasive contaminants into the system, accelerating wear on other expensive components like pumps and valves.

Regular visual inspections for any signs of hydraulic fluid leakage around cylinder rods are important. If you notice fluid weeping or dripping from a cylinder, it often indicates that the GLAND and its associated seals are compromised and need attention. Addressing these leaks promptly by replacing the worn GLAND and its seals is key to preventing further damage to the hydraulic system and restoring the drill's full operational capacity. Ignoring a leaking GLAND can lead to more extensive and costly repairs down the line.
