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

What are the verses describing the Dragon Boat Festival
The Dragon Boat Festival is approaching mid-summer, and when the people are cleared, they will grow again. -Tang Li Longji's "Dragon Boat Festival, Wucheng Hall, Banquet Group Officials" at four o'clock, with nine dumplings competing for the new. -Tang Li Longji's "Dragon Boat Festival, Three Halls, Banquets, Quds and Quds, Detecting Divine Characters" is also famous in official clothes, and the Dragon Boat Festival is honored by grace. Fine Ge contains soft wind and light snow. -Tang Du Fu's "Dragon Boat Festival Day Gives Clothes" is a regular bath orchid after the death of the spirit. Cai Lu bi jun zongzi, fragrant japonica white jade group. The dead are good and bitter, but today they are happy. -Tang Yuanzhen's "Ten Poems in the Summer" does not conform to the custom of Ai Fu, but the words of praying for Pu wine rise to peace. The temples are growing gray with each passing day, and the year of durian brocade shines through the eyes. -Tang Yin Yao Pan's Dragon Boat Festival

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

Geological Drill Pipe Classification and Selection Skills
Geological drill pipe classification and purchase skills Drill pipe consumer manufacturers bring you the classification of geological drill pipes and the purchase of geological drill pipes. According to different classification methods, geological drill pipes can be divided into: high-efficiency geological drill pipe, triangular geological drill pipe, geological geological drill pipe, wide-blade geological drill pipe, cfg geological drill pipe and long geological drill pipe. 1. High-efficiency geological drill pipe: the drill pipe body is made of high-pressure seamless alloy steel pipe, and the spiral blade is made of high wear-resistant T-shaped steel strip, which is prestressed and wound and welded. The drill pipe joint is made of high quality medium carbon diamond by vacuum conditioning and high pressure forming. This series of products using a four-way or six-way fast convergence mode, transport.

Surfacing technology for machining grooved drill pipe wear belt
With the decreasing of oil reserves in the near-surface layer, ultra-deep wells, high-angle wells and large displacement gradually replaced the traditional shallow and small displacement wells, which became the main way of oil drilling, and a large number of offshore oil drilling platforms appeared. The consequent problem is that the drilling time is greatly extended and the lateral force of the grooved drill pipe acting on the casing is increased from time to time, resulting in more prominent wear of the grooved drill pipe and the casing. Oil grooved drill pipe joint is a key component in the process of oil drilling, with the development of modern drilling technology from time to time, the request for the wear resistance of grooved drill pipe joint is progressing from time to time. So the progress of oil groove drilling

How to Correctly Maintain Slot Drill Pipe of Digger
How to correctly maintain the cutting drill pipe of the excavator We have said a lot of articles on how to maintain the rotary drilling rig. In fact, many of its components also require us to stop maintenance in our daily life. Today, I 'd like to take you to understand the maintenance methods of grooving drill pipes for small drilling rigs. Grooving drill pipes are very important components for our rotary drilling rigs. We should maintain them well. Groove drill pipe is the main force of rotary drilling rig construction, direct contact with the air, so we have to correct it to stop maintenance work. Correct maintenance can prevent the premature wear of the groove drill pipe, and is conducive to the timely repair of the damaged parts. False

About the installation and removal of the drill bit
The drill bit looks small, but its installation and use are still very exquisite. Familiar with it all know. Let's see what it's worth. First is the installation of the drill bit. Slowly lift the drill box, put the four legs of the drill box into the four holes of the drill rotary table, select the corresponding drill box core plate according to the specifications of the drill bit, lift the drill box core plate into the drill box, and then put the drill groove to be installed into the drill box corresponding to the convex point of the drill box core plate. Put the drill into the drill box, and the drill bit will be stuck in the rotary table core. Then screw the drill pipe with the connecting nut of the drill bit in turn. Again, the drill bit is disassembled. Lifting drill pipe (Attached
