The most commonly used connection method rig Shandong Dragon Industry Machinery Co., Ltd. is professional development, production of various types of mining equipment backbone enterprises, the production of various types of submersible drilling rig, water well drilling rigs and other products. Today, let us work together to understand the connection requirements for crawler drilling rig: The rig currently used connection method (1) snap connector technology, mainly used for metal pipe. Threaded connection can be divided into male and female connections and then planting snap connector. (2) welded connection percussive drill, it is divided into welded connection, mainly used for large-diameter pipe for quality: plastic welding engineering drill, mainly used for plastic pipe. (3) screw connection, and more for large diameter shallow wells. (4) adhesive, mainly used in plastic pipe and glass pipe. (5) socket connection, mainly for shallow long auger, down into the bell handcuffs iron pipes and hard PVC pipe. Submersible drilling rig is characterized mainly by the drill hole drill and drill pipe loading and unloading mechanism, set up drill down mechanism, slewing mechanism for the wind, lifting restructure some agencies, travel agencies, power and operating system, dedusting system components. Submersible drilling rig has the following characteristics: ① impact of a direct role in the brazing head, the energy transfer efficiency of drilling rigs, drilling speed is limited by the depth of color ring small; ② high-pressure gas or water high-pressure gas discharge powder, so that drilling of rock debris timely drained; ③ Gao drilling speed; ④ low noise, less dust. Submersible drilling rig according to their application areas are divided into hetero day to dive submersible drilling rig and two drilling rig, drill hole has been widely used in mining and hydroelectric projects. The open hole drill hole diameter and their quality trampling divided into three types: light submersible drilling rig, medium-sized submersible drilling rig, heavy submersible drilling rig. Rotary drilling rig, rig, industry machinery provided by the Long Machinery Co., Ltd. Shandong Long. Machinery Co., Ltd. Shandong Long (www.longyejixie.com) strong, credible, in Tai'an, Shandong Engineering Machinery Parts industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead industry machinery and you work long into the brilliant, for a better future!
