How to Prevent Mud Leakage of Tunnel Drilling Rig

In the process of mud drilling, mud leakage is often encountered. Due to leakage, it not only increases the consumption of mud, but also causes accidents such as borehole collapse, block loss, sticking and burying. In some areas, mud leakage is often a precursor to the discovery of aquifers. Therefore, mud leakage during drilling must be carefully judged and treated separately. There are two types of mud leakage in 1. drilling. One is to drill to the general aquifer, mud slowly leakage, this is a normal phenomenon. Another situation is encountered in rock fissures or caves, a large amount of mud leakage. This section refers to the latter case. Mud leakage occurs

Rotary digging machine drill pipe correct cleaning method

The drill pipe of rotary drilling machine is usually drilled with non-circulating mud. The drilling slag is brought to the ground through the lifting of the drill buckle of the rotary drilling machine to unload the slag. It cannot be directly carried to the ground through the cloud of mud to settle down. We call this slag unloading method of rotary drilling machine intermittent slag discharge. Today, let's say the cleaning method of the drill pipe of the rotary digging machine. When cleaning the drill pipe of the rotary excavator, we must first understand the cause of the sediment at the bottom of the hole. 1. Residue between bucket teeth of rotary drilling rig and bottom cover of drilling bucket. 2. The bottom cover is not closed tightly. 3. When drilling into mud and sand and flow plastic formation, the drilling slag in the drilling bucket is seriously lost during lifting, and sometimes even all of it is lost in the drilling hole. 4,

Causes of drill pipe slipping down during use of rotary drilling rig

After the current rotary drilling rig is used for a period of time, when the operating handle is returned to the neutral position during the lifting or lowering of the drill rod, the drill rod does not stop immediately, but always slides down several tens of centimeters before stopping. The drill pipe of the rotary drilling rig is caused to slip down. This paper talks about the common reasons and regular judgment of the drill pipe of the rotary drilling rig: 1. The drill pipe is fixed on the main hoisting drum through the steel wire rope, and the drill pipe can rise or fall accordingly when the drum is rolled or laid down. The power of the drum comes from the main winch motor which has been decelerated many times, and its stop is realized by the brake directly installed on the reducer. in the drill pipe

Manufacturing Process of Cemented Carbide Cutting Tools

Carbide tools are designed, tested, procured and manufactured for machining a wide range of materials such as aluminum, carbon and stainless steel, tool steel, titanium, cast iron, superalloys, copper and magnesium alloys, brass, bronze, composites, plastics and graphite. The carbide tool category includes high-performance and general-purpose CNC milling cutters, drill bits, drill bits, countersunk holes, roughing/finishing, reamers, routers, die-cut trimmers and custom special-purpose precision tools for industrial applications. Today, let's take a look at the manufacturing process of carbide cutting tools: 1. Tungsten carbide is mixed with cobalt to form a powder that can be classified as raw material. Mix the granular

Different usage of different drill bits

Drill bits are often seen in our lives and work, but all kinds of drill bits, will we distinguish their usage? Drill bits are classified according to cutting principles and can be divided into cutting drills, impact crushing and shearing drills, and grinding drills. According to the function classification, it can be divided into comprehensive drilling bit, ring drilling bit and special bit. Different drill bits, their range of use is also different. For example, drag bits are used for soft and plastic rocks with large torque, bad drilling tools and no moving parts. Cone bit is widely used in soft and hard formations, with small torque and cone rotation. Diamond drill bits for hard, highly abrasive formations, no activity

Drilling wells requires a deep understanding of groundwater and its types

The drilling method of diamond drill bit has replaced the traditional low-efficiency artificial well drilling. The water below the water level has become groundwater, which is formed by the water on the surface entering the ground below the ground through infiltration. The water on the ground includes all water resources such as rivers, rivers, lakes, etc. It is necessary to drill wells to transport groundwater to the ground by pumping pressure. In-depth understanding of groundwater and its types is of great help to successfully drill wells. Groundwater exists in the gaps between underground rocks or soils and can be divided into three types: upper water, phreatic water and confined water. 1, the upper layer of water closest to the surface of the water, direct contact with the atmosphere and surface water, this layer
