Mining hoses play an important role in mining operations, mainly used in hydraulic transmission systems such as coal mine hydraulic supports, comprehensive mining units, etc. Its working principle and scope involve multiple aspects.
Firstly, the working principle of mining hoses is mainly based on their special structure and performance. Mining rubber hoses are usually composed of an inner rubber layer, a reinforcing layer, and an outer rubber layer. The inner adhesive layer directly contacts and transmits fluid, requiring good wear resistance, oil resistance, and temperature resistance. The reinforcement layer provides the skeleton of the hose, usually woven from high-strength fibers or steel wires, which can withstand the pressure and tensile force of the fluid. The outer adhesive layer plays a role in protecting the reinforcement layer and preventing corrosion.
During work, mining hoses transmit liquids with a certain pressure and temperature (such as mineral oil, water-based hydraulic oil, or water) by connecting hydraulic pumps and hydraulic cylinders. These liquids play a role in transmitting energy and controlling motion in hydraulic systems. Through the transmission of rubber hoses, various equipment actions and functions can be achieved, such as the support and movement of hydraulic supports, and the operation of coal mining machines.
The working range of mining hoses is wide, not only suitable for coal mining operations, but also for various mining industries such as metal mines and non-metallic mines. In these industries, mining hoses are mainly used for conveying materials such as ore, coal, rock, slag, as well as liquids and gases. In addition, mining hoses are widely used in engineering construction, lifting and transportation, metallurgical forging, mining equipment, ships, injection molding machinery, agricultural machinery, various machine tools, as well as mechanization and automation hydraulic systems in various industrial sectors.
In mining operations, mining hoses usually need to withstand high working pressure, and general specification hoses can withstand working pressure of over 100MPa. At the same time, mining rubber hoses also need to adapt to different temperature conditions and have characteristics of high and low temperature resistance. These characteristics enable mining hoses to operate stably in complex and harsh mining environments, ensuring production efficiency and safety.
Overall, mining hoses achieve the transmission of liquids and energy in mining operations through their special structure and performance, providing reliable guarantees for the normal operation of various equipment. Its wide range of applications and excellent performance make mining hoses an indispensable and important component in mining operations.
