BODY CYLINDER(HEX1)

550 245 69 BODY ASSEMBLY A cylinder head is a fundamental part of any hydraulic cylinder, acting as an end cap that seals the cylinder barrel. It contains the hydraulic fluid under pressure, allowing it to act on the piston and generate the necessary force for movement. Without a properly functioning cylinder head, the hydraulic system cannot maintain pressure, leading to a loss of power and control. This component is crucial for the operation of cylinders found in various parts of an underground drill, such as the feed system, boom articulation, or even the rotation unit.

The integrity of the cylinder head directly impacts the drilling rig's overall performance and safety. A damaged or worn head can lead to external leaks, reducing hydraulic efficiency and requiring frequent fluid top-ups. More critically, it can compromise the cylinder's ability to hold position or exert full force, which affects drilling accuracy and speed. For instance, if a feed cylinder's head is failing, the drill string might not advance smoothly or with consistent pressure, impacting penetration rates and potentially causing drill string damage.

Typical signs of a failing cylinder head include visible oil leaks around the cylinder end, erratic or slow cylinder movement, or a complete inability for the cylinder to extend or retract. When these symptoms appear, it's important to inspect the cylinder head for damage or worn seals. Replacing a faulty cylinder head involves safely depressurizing the hydraulic system, removing the old component, and installing the new one with fresh seals. Always ensure proper torque specifications are followed during reassembly to prevent future leaks and ensure reliable operation.
