The well drilling boring method was first developed in North America in 1950. In the mid-1960s, the well drilling boring method was popular in Europe, especially in Germany. At that time, the  water well drill rig drilled a diameter of 1.2m and a depth of 150. ~200m; and by the early 1970s, the diameter of the borehole can reach 2.0-2.4m, and the drilling depth can reach 250-500m. Nowadays, many manufacturers in the world have produced anti-well drilling rigs, typically American Robbins. The company can provide 28 types of products, the diameter of the hole is 1.2 ~ 6.0m, the drilling depth can reach 900m, the HG100, 160, 210, 250, 330SP series produced by the German company Welt, the diameter of the hole is from 1.4 to 6.0 m, drilling depth up to 1000m. China has developed anti-well drilling rigs since the 1970s and has applied it in medium carbon and metallurgical systems. The products are mostly concentrated on small-diameter reaming boring machines. In 1992, the hydropower sys

Down-the-hole drilling rigs are used more and more widely in grouting operations, and most of the grouting reinforcement is open-air operations. This article mainly discusses how to choose the model of  crawler mounted DTH drilling rig s. 1.Selection principle (1) Applicable in production The selected drilling rig should meet the needs of the project construction, and should be reasonably configured according to the construction tasks undertaken by the enterprise under normal conditions, taking fully into account the scope of application of the drilling rig. Demand, only the drilling rig with strong applicability in production can better show its investment effect. (2) Technically advanced While meeting production needs, it is required to maintain its advanced performance indicators, which is conducive to extending its technical life. It will face obsolescence in the short term. In the long run, it meets the requirements of sustainable development of enterprises and can more

Down-the-hole drilling rigs are increasingly used in grouting operations, and most grouting reinforcements are performed in the open air. This article mainly discusses how to choose the model of  crawler DTH drill rig . 2. Selection of technical parameters of rig According to the requirements of grouting hole diameter, depth, and drilling angle, drill bits and drill rods of the same diameter and length need to be equipped to meet the technical requirements of drilling. At the same time, the drill arm and guide rail of the rig should have a variety of adjustable Angle to meet construction needs. A  crawler mounted DTH drill rig  can be equipped with drills of various diameter specifications, and can be flexibly selected according to the requirements of the construction aperture. The drilling depth is adjusted by using a small number of drill rods. The length of the drill rod is generally 2-9m, etc. The drill rod is connected by male and female threads. The outer diameter of the d

Drilling rig is a general term for a full set of drilling equipment. At present, the most widely used rotary rig in the world. The  hydraulic drilling rig  consists of a diesel engine, a transmission shaft, a drilling pump, a winch, a derrick, a crane, a traveling crane, a hook, a faucet and a turntable. According to the requirements of the drilling process, well cleaning, and drilling tools in the drilling process, a set of rigs must have the following eight systems and equipment. (1) Lifting system. In order to lower the drilling tool, the casing, and control the drilling of the drill bit, the drilling rig must have a set of lifting mechanisms. It mainly includes main winches, auxiliary winches (or cat heads), auxiliary brakes (water brakes, electromagnetic brakes, etc.), swimming systems (including wire ropes, cranes, cruises, and hooks), and derricks that suspend the swimming system. In addition, there are tools and equipment (lifting rings, elevators, tongs, slips, standing r

Disadvantages: Rotary drilling rigs are also constrained by various conditions such as the geological conditions of the stratum being constructed, the machine's own factors, and man-made factors such as the operator. There are some currently difficult situations to deal with, which are mainly not suitable for hard formations. In the initial stage of the use of rotary drilling rigs, blind superstition or lack of understanding of rotary drilling rigs can easily give people the illusion and cause misunderstanding, which directly affects the use of rotary drilling rigs. Rotary drilling rigs are also constrained by the geological conditions of the formation. In hard rock formations, dense cobblestones, and solitary rock formations, drilling becomes more difficult. Failure to replace the drill bit is prone to accidents. Although it can be equipped with core drills, impact drills, and grab cone drills for hard rock formations, pebble formations with a particle size of more than 100 mm,

Water Well Drilling Rigs  Supplier share with you: (1) protect the filter element. The function of the filter element is to filter the residual impurities in the oil and gas lines and prevent the impurities from entering the system.Various filter elements should be replaced regularly.When replacing the filter element, pay attention to check whether the old filter element is attached to metal debris.If metal particles are found, you should use a pure filter element that complies with machine rules for rapid diagnosis and an improved method. (2) different diesel oils should be selected according to different ambient temperatures. Impurities, lime soil and water should not be mixed with diesel oil. The bad quality of the  water well drilling rigs  can damage the fuel pump, and the defective fuel contains very high levels of ash and sulfur.It can cause damage to the engine.After daily operation, the tank should be filled with fuel to avoid water droplets on the tank wall.Please close
