Liu Jinshu, director of the Institute of Key Equipment of the Institute of Special Equipment for Heavy Industry Engineering, said that this is a coal roadway anchoring and anchoring device that can truly realize the construction work of digging and support, and a coal roadway anchoring device using shield protection; Taiwan coal excavation and anchoring equipment for multi-functional integration such as excavation, support, advanced drilling and evacuation. Imageually speaking, this equipment is like a giant “Pangolin†in the tunneling of coal mines. It has hard shells for support and drills in coal mines.
China is a big country in the use of coal machinery equipment and has a large market demand. Currently the in-service anchoring wind turbines all rely on imports, and the number exceeds 100 units. In the construction operation, the importing of the windlass cannot achieve the boring and support synchronization, and the roadway support takes a long time, which accounts for more than two-thirds of the total time of the tunneling; and the price is expensive, the delivery time is long, and the accessory supply is not timely, often affecting. Construction Schedule.
The R&D team of Tiejian Heavy Industry carried out targeted research projects and broke through the problems existing in the fast lane technology and process of the imported dig and anchor machine, realized the simultaneous operation of excavation and support, and improved the speed of the equipment lane and solved the problem. The problem of mining imbalances has long been plagued by coal mines. At present, the equipment has been granted 20 patents, of which 5 are invention patents, with complete independent intellectual property rights.
Industrial test data show that the equipment is safe and efficient to dig, the roadway is well formed, the anchoring quality is reliable, and the whole machine is powerful enough to fully meet the requirements of coal mine machinery construction. Under the conditions of post-matching belt transportation, the footage of Richeng Lane can reach 160 meters. The average monthly footage can reach 4000 meters.
The equipment also has an information management system and a digital operating system to provide an integrated solution for unmanned and mechanized construction of coal mines, which will accelerate the transformation of China's coal mining industry into an intelligent and green transformation.
Tungsten carbide welding bars are commonly used in the oil and gas industry for various applications. These bars are made from a combination of tungsten and carbon, which results in a very hard and wear-resistant material. Here are some specific uses of tungsten carbide welding bars in the oil and gas industry:
1. Hardfacing: Tungsten carbide welding bars are used for hardfacing applications, where a wear-resistant layer is applied to drilling tools, valves, pumps, and other equipment exposed to abrasive environments. This helps to extend the lifespan of the components and reduce maintenance costs.
2. Drill bits: Tungsten carbide welding bars are used to manufacture drill bits for oil and gas exploration. The hard and durable nature of tungsten carbide makes it ideal for drilling through tough rock formations.
3. Wear plates and liners: Tungsten carbide welding bars are used to create wear plates and liners for equipment used in oil and gas production. These plates and liners protect the underlying metal surfaces from abrasion and corrosion, ensuring the longevity of the equipment.
4. Valve seats and seals: Tungsten carbide welding bars are used to manufacture valve seats and seals for oil and gas valves. The high hardness and wear resistance of tungsten carbide ensure reliable sealing and prevent leakage in critical applications.
5. Downhole tools: Tungsten carbide welding bars are used in the manufacturing of downhole tools such as stabilizers, reamers, and drill collars. These tools are subjected to high pressures, temperatures, and abrasive conditions, and tungsten carbide helps to enhance their durability and performance.
Overall, tungsten carbide welding bars play a crucial role in the oil and gas industry by providing wear resistance, hardness, and durability to various components and equipment.
