Introduction to Drilling Machinery
Бұрғылау machinery is essential equipment in various industries, playing a crucial role in activities such as oil and gas exploration, mining, construction, and water well drilling. It is designed to create holes in the ground or other materials with high precision and efficiency.
The history of drilling machinery dates back thousands of years. Early humans used simple tools like pointed rocks spun between their hands to bore holes. Over time, more sophisticated methods were developed. Мысалы, the bow drill, which converted back – and – forth motion to rotary motion, emerged around 10,000 years ago. It was used not only for creating fire but also in woodwork, stonework, and even dentistry in ancient times.
Modern drilling machinery comes in a wide range of types. Rotary drills are very common. They involve a cutting or grinding action to break through materials. The simplest rotary drill is the earth auger, which is hand – operated and similar to the wood auger used in carpentry. It is mainly used for drilling holes in relatively soft earth. There are also different types of drill bits for rotary drilling, such as drag bits for soft rock, roller bits for harder rock, and diamond bits that grind away the rock. Core – type diamond bits are used for prospecting as they can provide a sample cross – section of the penetrated strata.
