In the mean time, we are also an established engineering solutions provider offer products and services that make global trade faster, smarter and more sustainable.

The essence of the Down the Hole Drill is to make the impactor dive into the hole during the rock drilling process to reduce the energy loss caused by the impact energy transmitted by the drill rod, thereby reducing the impact of hole depth on rock drilling efficiency. . The rock drilling equipment for down-the-hole drilling is a down-the-hole drilling rig.

An air compressor is an expensive investment in any production facility. With frequent usage, especially in high-performing businesses, it’s easy to forget that it needs routine maintenance to function effectively.

Purchasing an air compressor is not the beginning and end of it. Like all machinery, after extensive use, minor wear-and-tear issues can occur. However, if these problems are overlooked, they can develop into major costly repairs.

For water well drilling rigs, the general requirements are. It has simple configuration, low energy consumption, easy operation, strong maneuverability, multi-function and small size. In practical applications, the drilling rig must be selected based on the stratum, hole diameter and depth, and drilling method.

While price is the most common consideration for many people, there are many other aspects to consider – some of which may outweigh the impact of price. Think service and support, training and quality.

RC, or reverse circulation, drilling is a tried and true drilling method in certain circumstances. Drillers usually use it on large-diameter holes because it is faster and easier to clean the hole. The fluid and cuttings flow up the drill pipe and down the annulus. In softer formations, this causes less washout and makes sampling faster and more accurate because cuttings are not contaminated by sloughing formation off the hole walls. They also come up the drill pipe very fast, giving an accurate formation log.

Among all the drilling method, Down The Hole(DTH) drilling is being used more and more widely and has very high efficiency for some cases. Here, we will introduce DTH drilling as most important part of whole basic drilling knowledge.
