EYE, CYLINDER

BG 007 919 72A EYE, CYLINDER A feed cylinder plays a vital role in the drilling process by converting hydraulic pressure into linear motion. It's mounted on the feed beam and precisely controls the movement of the drifter, pushing the drill string into the rock face and retracting it when needed. This controlled advancement is crucial for maintaining optimal penetration rates and preventing the drill bit from getting stuck.

When a feed cylinder operates correctly, it ensures a steady and powerful thrust, directly influencing how fast and efficiently the rock is drilled. Any issues, such as internal seal wear or external leaks, can lead to inconsistent feed force, jerky movement, or a complete loss of drilling power. This not only slows down operations but can also put undue stress on other drilling components, potentially leading to premature failures and increased downtime.

Common signs of a failing feed cylinder include a noticeable drop in penetration rate, the drifter moving unevenly, or visible hydraulic fluid leaks along the cylinder body or rod seals. If you observe these symptoms, it's important to inspect the cylinder promptly. Often, replacing worn seals can restore function, but severe damage to the cylinder bore or rod might require a complete unit replacement to ensure reliable and safe drilling performance.
