Some suggestions for reducing the wear of the drill string are worth studying!
The drill pipe is a rod connected in the drilling tool to transmit power. The drill pipe is a steel pipe with a thread at the tail, which is used to connect the surface equipment of the drilling rig and the drilling equipment or bottom hole device at the bottom of the drilling. The usual components of the drill pipe are: drill bit, drill collar, drill pipe, stabilizer, special joint and kelly pipe. The purpose of the drill pipe is to carry drilling mud to the drill bit and raise, lower or rotate the bottom hole device together with the drill bit. The drill pipe must be able to withstand huge internal and external pressure, distortion, bending and vibration, so the wear of the drill pipe is a very serious problem. When the drill pipe is worn to a certain extent, it should be replaced with a new one.

How to choose the right tunnel drilling rig?
The so-called tunnel drilling rig is driven by the engine hydraulic oil pump, and finally the tunnel drilling rig has the functions of drilling and rotating, so as to realize the purpose of pipeline trenchless construction. Then, in the process of using horizontal drilling rig to complete the project, which characteristic of the drilling rig has the greatest impact on the project? There is generally a vague concept: when selecting tunnel drilling rigs, tension is the main data, and other data are easy to be ignored. the correct principle should be: first look at whether the tension value of the drilling rig is within the required range, and the output torque of the drilling rig and the parameters of the drill pipe are the key data. of course, these capabilities of the drilling rig are started by the heart of the drilling rig.

Rib drill pipe series product introduction
1. rib drill pipe introduction rib drill pipe in the construction process of rotation resistance is small, slag effect is good, can be applied to various types of formation, and can be quickly disassembled by disassembly device, improve the construction efficiency, saving labor and material costs. Because the spiral blade is wide and has high hardness, the rib drill pipe has a good slag discharge effect and is suitable for various hardness and various types of formations. In addition, due to the wider spiral blade, the rib drill rod will not cut the hole wall of the drilling hole during the drilling construction process, and will not cause the hole wall to be inclined and affect the drilling effect. Rib drill pipe is divided into taper thread connectivity and hexagonal

Matters needing attention in the use of drill pipe
When using for the first drilling, it is necessary to "grind the new buckle" first, which includes the technological innovation of applying screw thread oil first, then using the drilling machine to tighten the buckle with full strength, opening the buckle for domestic demand, applying screw thread oil and opening it again, and repeating this for three times to avoid new wear and buckle. As far as possible to maintain the drill pipe under the ground and on the ground in a straight line, so as to avoid the thread part side force and cause unnecessary wear and extremely low, or even jump buckle drill pipe, pay attention to the rig anchor to avoid the construction of the force movement is very important. When using a new drill pipe, it should be determined that the screw thread of the front section of the drill bit (protecting the shaft head) is also close to the turning head of the new bad buckle.

Factors Affecting Selection of Rotary Digger Bit
The rotary drill bit is the main component of the rotary drilling rig, which determines the thickness of the rotary digging bottom layer. At the same time, the construction requirements are different, which will eventually affect the progress of the construction, so it is very important to choose the drill bit of the rotary excavator. Let's look at the factors that affect the rotary drill bit. Geology is diverse, which determines the type of rotary drill bit. In the pebble drilling special drilling pebble rotary drill bit, so according to your drilling geology to distinguish. Helps you complete construction tasks quickly. Another point is that different rotary drilling rigs have different rotary drilling bits installed, which is also one of the influencing elements. Like surface soil, muddy sub-clay, clay layer in dry state

Correct use of CNC drill includes what aspects?
The drill bit has a strong impact force when it is changed, so the drill bit device can adapt to any type of formation. The drilling speed of CNC drills has been greatly developed. How to use CNC drills correctly mainly includes the following aspects: Tip runout 1. Select the correct machine tool. CNC drills can be applied to CNC machine tools. Machining centers have high power and good steel performance, and the knife TIR should be guaranteed to be <0.02. The rocker drill, universal milling and other machine tools due to the power is small, the spindle accuracy is poor, easy to lead to the early collapse of the CNC drill bit, should try to avoid. 2. Choose the right hilt, spring clip

What are the basic components of a rig and what do they do?
The drilling rig is mainly composed of four major parts: rotary mechanism, feed mechanism, lifting mechanism and frame. The rotary drilling tool drives the drill bit to work at the bottom of the hole. Feeder mechanism: adjust the drilling pressure required for the drill bit to work at the bottom of the hole and control the feed speed; Lifting mechanism: used to complete the lifting of drilling tools, casing and ancillary work. Some drilling rigs also use the lifting mechanism to control the feed speed and feed pressure. Frame: according to the characteristics of the overall layout of the drilling rig, the above components are assembled into one or two whole, to achieve the requirements of compact structure, easy installation and disassembly.

Causes and treatment scheme of drill pipe sticking of rotary digging machine
Rotary drilling machine has the characteristics of large installed power, large output torque, large axial pressure, flexible, high construction efficiency, and environmental protection. With different drilling tools, it can be said that it is the most ideal machine for hole-forming work in construction projects. Also because of its high efficiency, environmental protection, high efficiency advantages, access to the construction unit. The problem of sticking in the process of work should be dealt with according to the depth of sticking, formation and other related factors, and corresponding countermeasures should be taken. The following is a specific look at the reasons for the sticking of the drill pipe of the rotary excavator and how to solve the sticking. 1, due to hole collapse or equipment itself caused by sticking drill, sediment thickness is large, to first clean the hole, and then use the drilling rig or auxiliary

What factors should be considered in the matching of drill pipe and drill bit?
Diameter difference is the primary factor we consider. Diameter difference refers to the difference between the diameter of drill pipe and the diameter of drill bit. As we all know, the diameter of drilling hole is caused by the diameter of drill bit. According to the requirements of drilling technology, the diameter of drill pipe should be smaller than that of drill bit. In the drilling process, it is beneficial to the discharge of cinder. Reasonable diameter difference can reduce the friction force of drill pipe.
