Rig operation: operation skill mainly lies in pressurization
From the outside, the rotary drilling rig gives the feeling of being very tall, and it feels like the handle after entering the cab. There are many buttons, which generally gives people a complicated feeling. However, the fact is also true. From the positioning of the machine to the auxiliary working condition, and then to the drilling under the main working condition, there are indeed many actions required. However, in order to open the rotary drilling rig well, pressure is the most important among the many operating actions! The pressurization we mentioned here is not blindly downward pressurization through the handle, but to control the pressurization intensity and pressurization time for different rock and soil bottom layers. The routine is as follows: lifting suspension point floating long floating point pressurization short stroke pressurization long stroke

Operating Regulations for Full Hydraulic Drilling Rig
(1) Use the operating handle of the console to control the rotation and advancement of the drill pipe. When the operating handle is pushed forward from the neutral position. The drill bit rotates clockwise to drill holes or install drill pipes: when the operator pulls the handle backward from the neutral position, the drill bit rotates counterclockwise to remove the drill pipe. (2) Push the operating handle of the feed oil cylinder to control the drill bit to move forward when pushing forward or backward, and to move backward when pulling backward. (3) When it is necessary to advance or retreat quickly, the quick operation handle can be manipulated. The operation mode is the same as that of the feed cylinder. That is, push forward and pull backward. (4) the use of throttle control feed speed. Hands.

Introduction of Φ28 Quick-connect Spiral Drill Pipe
1. product features Quick-connect spiral drill pipe is developed on the basis of absorbing the advanced production technology of Germany and integrating the latest research results of our company. The drill pipe body is made of high-pressure seamless alloy steel pipe, and the spiral blade is made of high wear-resistant T-shaped steel strip, which is prestressed and wound and welded. The drill pipe joint is made of high-quality medium-carbon alloy steel, which is subjected to vacuum conditioning and high-pressure forming. Quick-connect spiral drill pipe adopts the quick connection mode of square or hexagonal, which is automatically locked by spring pin when used, and is equipped with U-shaped or semi-ring anti-release pin to make the torque of drill pipe reach the best state. The quick-connect spiral drill pipe is mainly used with portable or hand-held drilling rig. The weight of the drill pipe is light, the connection is rapid, and the slag discharge speed is fast, which greatly improves the work efficiency, so it is called the quick-connect spiral drill pipe. Quick connect spiral drill pipe is widely used in drilling construction of water exploration and gas exploration under geological conditions of coal seam and near coal seam. It is divided into water type and water type 2. product description 1. Quick connect spiral drill pipe needs regular maintenance to determine the maintenance period, and regular rust and dust prevention treatment. 2. The use of quick-connect spiral drill pipe shall be within the rated drilling distance of the drilling rig, and the matching drill pipe shall be adopted according to the technical parameters and models of the drilling distance. 3. Quick-connect spiral drill pipe is made of friction welding of special geological drilling pipe for mining geology and its matching joint, so it has good follow-up and high tensile strength, and can be adapted to drilling and gas discharge in regular. When working in hard rock, coal seam or other special environment, the drilling depth shall be determined according to the physical properties and parameters of the actual material of the drill pipe. 4. When the quick-connect spiral drill pipe is used with the drill bit, the drill bit should be larger than the diameter of the drill pipe under normal circumstances, and the condition of the drill and the drill pipe should be paid attention to at all times during the drilling process. In case of sticking, sudden death, etc., stop drilling immediately or drill slowly after returning to ensure that the drill pipe is not bent and flat. 5. When the quick-connect spiral drill pipe is ventilated or ventilated, the drill pipe shall be tightly connected during drilling. When the drill pipe has a seal, such as O-ring seal, pay attention to the use of the seal, in the event of damage, corrosion and other phenomena, to replace the seal in time. After the drilling is completed, do maintenance and cleaning work on the seal. 6. When drilling, the quick-connect spiral drill pipe shall be tightened manually to ensure close fit (thread type). It is not allowed to drill directly with the drilling machine to prevent damage to the drill pipe. 7. If the bending degree of the drill pipe after use exceeds the standard requirements or the thread damage causes the normal operation to be impossible, the drill pipe shall be scrapped or returned to the factory for repair in time. 8, according to the standard requirements, should ensure the drilling depth of the drill pipe composite geological drilling related requirements to prevent the drill pipe due to the drilling depth to reach the limit of the use of the drill pipe, the occurrence of falling off phenomenon. 9. When working in acid and alkali areas, attention should be paid to the corrosion of drill pipes. When drilling is completed, clean the surface of the rod body with clean water in time to remove the corrosion layer. 10. The quick-connect spiral drill pipe shall be stored in a dry place, the bottom shall be supported at multiple points, and the drill pipe shall be regularly maintained during long-term storage. 11. The drill pipe shall not be used as a supporting platform for heavy tail stacking, and the drill pipe shall not be randomly placed under gravel, coal pile or scattered pile. 12. Quick-connect spiral drill pipe maintenance After rust removal/dust cleaning, protective caps shall be buckled or packed and sealed to ensure that the drill pipe is often new.
