How rotary drilling rig works, what works? Currently rotary drilling rig works the drill pipe in the form of multi-use connection bucket dig and dig slag slag during drilling in the use of mud circulation mode, engineering drilling rig, mud lubricant for such rigs, support, replacement and carry drilling residue role. With the urban construction and environmental protection requirements become more stringent, the traditional rig face greater crisis. The rotary drilling rig power head forms and rotary drilling rig working principle is to use a short screw drill or auger bucket, using the powerful torque directly to the soil or gravel mining and other rotary drilling residue, and then quickly make holes outside, without the need for mud Supporting the case of dry construction can be achieved, Taian engineering rig, even in the case of special needs Slurry Wall formation, the mud also play a supporting role only, works with the rig, the drilling mud content is very low, which makes pollution greatly reduced, thereby reducing the construction cost, but also improve the construction environment, high efficiency into the hole. This is the rotary drilling rig with good environmental properties. What factors will influence rig drilling rig by the use plays an important role in industrial production, it is widely used rig to make people's work efficiency has been improved, but in the rig application Many factors affect the efficiency of this rig, where the effects of different strata of the rig is great, here we come to you specific about this knowledge. Mudstone from the crystalline particles composed of fine-grained, with cementation, slippery water, combined with mud lubrication, adds to the difficulty of drilling! Typically there will be slippery shale drilling, sticking, fighting bad end closed phenomenon. Construction process, if you can dry hole drilling, auger drilling more efficient fight; due to the nature of mudstone, holes appear immediately once the water slipping, so slippery with water or mud are directly related. When using a double-dip picks shale drilling bucket drilling water holes, due picks drilling way is to use the front of the drill head alloy, alloy head very easy to break into the mud, but the pick body too blunt, they form a resistance, so as to achieve less than a crushing effect, and therefore can not be sustained drilling, water or mud into the cut and lubrication, will form between the teeth and the slippery mud. Pebble geology in our country is very broad distribution area, mainly in rivers and geological sedimentation plains are more common, Shandong Engineering rig, construction of drill wear very serious individual geological drilling difficult problem there. Sand and gravel stratum of bit wear large drill bit tooth must be frequently changed. For more professional rig is used to directly drive casing drive casing, to be more professional rig with casing for the drive directly drive casing, when combined with tight gravel layer, hardness auger drilling or drilling difficulties can not be used Cartridge core bits, after the first layer of loose gravel, then auger drilling. Engineering drilling rig use, Dragon industry machinery (online consultation), engineering by Shandong Dragon Machinery Co., Ltd. with the rig. Machinery Co., Ltd.
