6 FAQs about [Rock drill gas flushing mode diagram]

How does a rock drill machine lubricate oil?

The compressor is driven directly by the diesel engine. The compressor element is lubricated by an air-oil mixture. The mixture is separated in the oil separator. The system supplies air for flushing the drill hole, cleaning the dust collector filter and for the rock drill machine's ECL lubricating system to oiling the drill steel threads.

What is a drill rig instruction manual?

This instruction manual is part of the complete delivery of the drill rig. It provides information on the design and operation of the drill rig and contains advice and the measures necessary to keep the rig operational. This instruction manual is no replacement for thorough training on the drill rig.

How does a rock drill work?

The hydraulic pumps and the compressor are driven by a diesel engine. The boom system consists of boom body, telescopic boom, boom head, feed holder and associated hydraulic cylinders. The boom system is controlled by directional valves for positioning the feed with the rock drill at different distances and direc-tions.

What is a diesel drill rig?

This drill rig is a fully diesel-hydraulic drill rig designed for surface drilling applica-tions such as in quarries and on construction sites. The diesel engine, chassis, dust collector, hydraulic system, air system and boom system are mounted on the wagon frame.

How do I install a new rock drill rod?

Operate the drilling lever (A) to position (e) to unscrew the shank adapter from the drill rod. Press the button (S449) to activate the rapid feed function and then operate the drilling lever to position (c) to move up the rock drill to a proper position for add-ing a new rod. Operate the DCT/RHS control lever (S803) to position (b).

How do you control fugitive dust in a drill rig?

Dust-suppression and crushed-rock-cutting collection systems are available on many drill-rig models to help control fugitive dust. Rubber skirts and water-misting controls contain rock fines and dust around the blasthole collar. Cyclone mechanical dust collectors remove drill cutting from the hole collar and place them alongside the drill rig.
