Summary: We know that the torque of the trailer rig is fixed, so how does the torque value of the drill pipe come from those factors?
The factors of the torque value of the drill pipe are composed of the following aspects, which are now available for sale: the torque value of the drill pipe is mainly composed of the specifications, materials, joint forms of the drill pipe body and changes in the production process.

What is the torque value of the drilling rig and what are the factors
We know that the torque of the trailer drilling rig is fixed, so how does the torque value of the drill pipe come from and are composed of those factors? Xiaobian also consulted the technology before he learned about the impact of drill pipe torsion.
Next
The factors of moment value are composed of the following aspects, which are sold now: the torque value of drill pipe is mainly caused by the specification, material and joint form of drill pipe body and the change of production process.
The same performance conclusion. The change value is caused by different materials and processes. The drilling depth of the drill pipe is related to the torque of the drill pipe, but the drilling depth is not determined by the torque of the drill pipe.
According to different geological conditions and the selection of drill pipes suitable for large trailer drilling rigs, drill bit types to determine the drilling depth. In this way, the torque of the drill pipe and the drilling rig is selected well, and then selected according to the geological conditions of the operation.
After selecting the corresponding drill pipe, select the matching drill bit to apply I. Of course, these are all theoretical data, and specific problems can be analyzed in the construction process.
Drill bit is one of the important drilling tools in the drilling of water well drilling rig-first, it can be said that without drill bit, large trailer drilling rig cannot be started up and produced normally, thus showing the importance of drill bit in water well drilling rig.
For different types of water well drilling equipment, different drill bits are required in production. When selecting drill bits for water well drilling equipment, the following aspects should be paid attention to: 1.
When producing in a good soft rock, the speed of study is faster, and it is necessary to choose a four-wing shape with a larger amount of slag discharge and a higher quality of slag discharge. 2, in the production of hard rock, due to the rock
The strength is larger, and each column tooth and drill bit need to bear a larger amount of load, so it is necessary to choose a drill bit with a higher strength of the drill bit body and column tooth. 3, in rock drilling containing clay,
As the clay is relatively loose, the slag discharge hole is often blocked, and the side slag discharge drill bit can be selected. 4, trailer drilling rig manufacturers in the toughness of the better rock drilling, you can choose the wedge
Tooth bit, to ensure safe production.
The principle of disassembly of trailer drilling rig is generally to dismantle after installation, and dismantle after installation. The following matters should be paid attention to when the rig accessories are reminded to be disassembled: the disassembled gas, liquid and water pipelines should be sealed and kept
The inside and interface of the drilling rig pipeline shall be cleaned to avoid the entry of foreign matters. The fasteners shall be packed separately and labeled or packed in the packing box when the drilling rig is disassembled. Spirals for connections everywhere,
Nuts should be packaged separately to avoid confusion between high-strength screws and nuts and other screws and nuts. The software of the air system should avoid oil, and the external threads of each pipeline should be wrapped with clean plastic cloth to avoid threads.
Bump and keep the tube clean. It is forbidden to fall or touch during disassembly and hoisting of large trailer drilling rig to avoid damage to the parts. If it needs to be transported over a long distance or stored for a long time, it should be protected from rain, moisture and rust.
management, and make box packaging, fill in the packaging list. All liquids (oil, water) in the equipment shall be drained clean.
Trailer rigs use the weight of the drilling tool itself to impact the formation. The lower end of the drilling tool is provided with several sharp-angle grasping flaps that can be opened and closed. When the drilling tool moves downward under its own weight, the grasping flaps open and cut into the rock.
Layer, and then by the winch through the wire rope to lift the drilling tool, catch the flap in the process of closing the debris into the cone, put out the wellhead to discharge the debris. Drilling depth is usually 40~50 meters, up to 100~50 meters deep ~
150 meters. Wire Rope Percussion Drill. It is composed of mast and lifting pulley, wire rope, impact mechanism, drilling tool, motor, etc. When the trailer rig manufacturer is working, the motor is on.
The impact mechanism is driven by the transmission device to drive the wire rope to make the drilling tool move up and down. When moving down, the weight of the drill bit cuts into and breaks the rock layer, and the upward movement is pulled by the wire rope. Drill
The head stroke is 0.5~1 m, and the impact frequency is 30~60 times/min. Rock cuttings are removed from the ground by the sand pumping cylinder, and drilling and removal of rock cuttings are carried out at the same time.
Maintenance content of trailer drilling rig: clean the surface of the drilling rig, pay attention to the cleaning of the surface of the base slide, vertical shaft, guide rod, etc., and keep good lubrication; check all exposed bolts, nuts, and bolts.
Whether the dangerous lock nails are firm and reliable; lubricate as required; check the oil level of the gearbox and transfer case; check the oil level of the hydraulic oil tank; check the oil leakage and air leakage, and eliminate them; eliminate them in this class
Other faults that have occurred. Weekly maintenance of drilling rig: shift maintenance; vertical shaft box with lubricating grease; eliminate grease or dust on hydraulic chuck and lower chuck; moisten according to weekly maintenance requirements
Slide; clean the inner surface of the brake. Monthly maintenance content of large trailer drilling rig: weekly maintenance content; Remove the chuck, clean the slip, slip seat, disc spring, etc., and change the oil for the thrust bearing;
Fill the beam bearing with lithium-based grease; clean the oil tank filter and replace the deteriorated hydraulic oil; check the lubricating oil in the gearbox, transfer case, and gyrator. If it deteriorates, replace it in time; check all parts
If there is any damage, replace it in time and do not work with illness.
