Precautions for the use of diamond compact drill bits
Answer: 1. During normal operation, it is strictly prohibited to suddenly reverse and change the operation direction to prevent the composite drill bit from falling off; 2. During normal operation, there should be no air leakage in the main air path of the air compressor. Sufficient air volume and air pressure should be ensured to prolong the service time of the diamond composite drill bit. 3. When the new composite drill bit is used for the first time, it should be run in at low speed for half an hour before normal use; 4, in the harsh geological environment, to reduce the shaft pressure and speed, to prevent the drill bit fracture; 5, in the normal drilling operations, if the midway to replace the drill bit, to strictly check whether there is debris in the hole, must ensure that the hole clean before using the new composite drill

Performance advantages of quick-connect spiral drill pipe
Answer: Main features: The quick-connect spiral drill pipe body is made of high-pressure seamless steel pipe, the drill pipe joint is made of 42CrMOA high-quality alloy structural steel through vacuum quenching and tempering treatment, and the drill pipe body is welded by advanced high-pressure interference assembly process and friction welding process. The spiral blade is made of high-wear T-shaped steel belt, which is welded by prestressed winding and full-automatic welding equipment. This series of products adopts four-way or six-way quick connection, which is automatically locked by spring pins when used, and is equipped with U-shaped or semi-circular anti-release pins to make the torque and drilling depth of the drill pipe reach the best state. Main process: quick-connect spiral drill pipe mainly adopts cold installation, hot installation, friction welding and other processes, in which cold installation process refers to the pre-processed inner square hole at both ends of the rod body, and then one end of the square steel is inserted into the pre-processed inner square hole to drill welding spot holes and pin holes for fixation, which is applicable to all quick-connect spiral drill pipes. hot installation process refers to the pre-processed inner square hole at one end of the rod body, at the other end, after the rod body is heated, the square steel is installed on the fixture, the square steel is directly pressed into the rod body, and then the hole is drilled and the pin is pressed and welded, which is suitable for F18, F24 and F32. The friction welding process can be applied to all quick-connect spiral drill pipes. At present, with the gradual improvement of the process, the friction welding process will gradually replace the existing cold and hot processes in the quick-connect spiral drill pipe, which greatly improves the comprehensive mechanical properties of the quick-connect spiral drill pipe.

Introduction to Quick-connect Spiral Drill Pipe
Definition of quick-connection spiral drill pipe: quick-connection spiral drill pipe is a spiral drill pipe that can be quickly connected by spring pin automatic locking or semicircular pin, straight bolt, U-shaped pin and oblong wedge pin for connection and positioning. The connection is convenient and quick, with the characteristics of light weight, high elasticity and not easy to bend. Compared with other drill pipes, it has obvious advantages of convenient operation and fast drilling speed, so it is called quick-connect spiral drill pipe. The broad range of quick-connection spiral drill pipes: in custom, quick-connection spiral drill pipes refer to Φ φ42mm, Φ φ69mm and Φ φ72mm, and we position them as square steel quick-connection drill pipes in sales. In a broad sense, it also includes other drill pipes with quick connection: such as water detection drill pipe, gas discharge drill pipe, calibration drill pipe, rattan and hemp drill pipe, and large-scale drill pipe overlapping with geological spiral drill pipe. Quick-connect spiral drill pipe connection: there are three types, namely, square, hexagonal and threaded connection of some models, of which the four-way connection is the most commonly used. Quick-connect spiral drill pipe executive standard: welding structure soft rock drill pipe and drill bit MT/T904-2002. The quick-connect spiral drill pipe manufactured by our company is largely higher than the industry implementation standard, which provides a guarantee for the actual drilling needs of customers. Quick connect type spiral drill pipe application scope: widely used in coal seam and near coal seam geological conditions of drilling, coal mine water exploration and gas discharge drilling construction, can also be used in geophysical exploration and water conservancy construction project anchoring, drilling construction and other fields. Definition of torque: Torque is a special moment that causes an object to rotate. The international unit is Nm N.m. The torque of the engine refers to the torque output by the engine from the crankshaft end. Under the condition of fixed power, it is inversely proportional to the engine speed. The faster the speed, the smaller the torque, and vice versa. The external torque is called torque or external torque, and the internal torque is called internal torque or torque. Factors affecting the torque value: the torque value of the drill pipe is mainly caused by the specifications, material and joint form of the drill pipe body and the change of the production process. Among them, the change value is due to the difference of materials and processes. The drilling depth of the drill pipe is related to the torque of the drill pipe, but not absolutely by the torque of the drill pipe. To determine the drilling depth, the drilling depth should be determined according to different geological conditions and the type of drill pipe selected.
