DOSING ELECT

DOSING ELECT 3716 6932 01 An electrically actuated dosing valve plays a crucial role in maintaining the health and efficiency of a rock drilling rig. This component is designed to precisely meter and deliver a controlled amount of fluid, most commonly lubrication oil, to vital areas such as the drifter's internal mechanisms or the shank adapter. Its operation is typically managed by the rig's control system, ensuring that lubrication is applied exactly when and where it's needed during the drilling cycle.

Proper functioning of a dosing valve directly impacts the lifespan of expensive wear parts and the overall reliability of the drilling operation. If the valve fails to deliver adequate lubrication, components like the drifter piston or rotation chuck can experience excessive friction, leading to premature wear, overheating, and potential seizure. Conversely, an uncontrolled flow might waste lubricant or, in some cases, cause other operational issues. Maintaining consistent lubrication is key to achieving consistent penetration rates and reducing unexpected downtime.

Common signs of a faulty dosing valve include unusual noises from the drifter, excessive heat build-up in lubricated areas, or visible wear on components that should be well-lubricated. Sometimes, the rig's diagnostic system might show a fault code related to lubrication flow. When replacing this valve, it's important to ensure the electrical connection is clean and secure, and that the new part is correctly installed to maintain the precise dosing required for optimal machine health.
