AIR VENTIL

551 652 39 VENTIL, AIR, das innerhalb des pneumatischen Kreislaufs der Anlage arbeitet, leitet dieses Ventil Hochdruckluft zu einer bestimmten Funktion, am häufigsten zum Spülen von Gesteinsschnitten aus dem Bohrloch. Its correct operation is essential for maintaining a high rate of penetration. By precisely managing airflow, it allows the drifter to work efficiently without wasting expensive compressed air, a significant operational cost in any underground mine.

A failure in this AIR VENTIL can lead to several drilling problems. If the valve sticks closed or becomes clogged, flushing air will be insufficient, causing the drill bit to jam and potentially damaging the drill string. Conversely, a valve that leaks or sticks open leads to a constant loss of air pressure, reducing the overall performance of the rig and placing extra load on the compressor.

Common signs of a worn AIR VENTIL include a noticeable hissing sound from leaks or a weak, inconsistent flow of flushing air at the front of the drifter. When replacing the valve, always ensure the pneumatic system is fully depressurized. It's also good practice to inspect the connecting air lines for moisture or debris, as contamination is a primary cause of premature valve failure.
