Working principle and explanation of down-the-hole drill

A down-the-hole drill, usually called DTH by most professionals, is basically a jackhammer screwed on the bottom of a drill string. The fast hammer action breaks hard rock into small cuttings and dust that are evacuated by a fluid (air, water or drilling mud).. A down-the-hole drill, usually called DTH by most professionals, is basically a jackhammer screwed on the bottom of a drill string. The fast hammer action breaks hard rock into small cuttings and dust that are evacuated by a fluid (air, water or drilling mud).. In down-the-hole drilling a drill rod is fitted with a hammer at its lower end. The hammer, which is mounted on the drill bit, is activated through the addition of compressed air and driven into the ground – simultaneously rotating and impacting.. Down-the-Hole (DTH) drilling is a technique used to create deep, precise holes in hard rock and challenging ground conditions. In this method, the hammer and drill bit are placed at the bottom of the drill string, directly engaging with the rock. [pdf]

Diesel driven air compressor principle diagram

When you turn on the engine, the battery powers the pistons in the cylinder up and down. The pistons push the air through the cylinders, into a combustion chamber where it is compressed. Compression forces the molecules in the air to move faster, which naturally heats the air. Fuel is then injected into the hot,. . While the above process occurs, additional fuel is delivered by the system. The fuel is pumped from the fuel tank, passing through filters, a higher pressurization pump,. . During the ignition process, air is also pumped to the cylinders. On some engines, this air passes through a simple air cleaner en route. [pdf]

Electric air compressor overheating

When an air compressor overheats, the problem is generally related to factors involving irregular suction or discharge pressure. However, the problem could also stem from insufficient ventilation, insufficient or eroded oil, or any given number of issues related to the wear and tear of machine parts. Here are. . If your air compressor is behaving abnormally, there is no doubt a problem that more often than not will stem from the air compressor overheating. If you experience any of the following 4 symptoms then it’s likely that your air compressor is indeed. . If you have any questions regarding why your air compressor overheats, please leave a comment below, with a photo if applicable, so that someone can help you! . People often wonder about the methods to cool down an overheated compressor. And as simple as it sounds, all you have to do is cease. But overheating is a common issue that can hurt efficiency, lead to expensive air compressor repairs, or even cause system failure. This guide breaks down how air compressors work, why they overheat, what happens when they do, and the warning signs to catch problems early. [pdf]
