Let's discuss the production equipment for high-pressure steel wire spiral hoses. The main manufacturing equipment for high-pressure hose assemblies includes: rubber stripping machines, electric pressure testing pumps, crimping machines, and cleanroom cutting equipment, among other domestic manufacturing equipment. Our company's production system for high-pressure hose assemblies is zero-pollution. Every product undergoes strict pressure testing before leaving the factory, ensuring an extremely high qualification rate.
When it comes to "high pressure," this requirement is determined by the application characteristics of the hose and the system pressure, which establishes the maximum working pressure of the hose. Every type of hydraulic hose has a basic working pressure, and its engineering burst pressure is typically 3 to 4 times the working pressure. The higher the pressure, the more layers of steel wire reinforcement are required, and the more meticulous the manufacturing process must be. Therefore, by determining the actual system pressure and selecting the appropriate maximum working pressure for the hose, you can ensure normal system operation while choosing a hose with the right working pressure. If the system experiences frequent surge pressures, it is necessary to use hoses with a relatively high pulse service life. Additionally, it is essential to enhance your understanding of hydraulic hose technical specifications and product classification.
Ambient temperature is also a key factor for users to consider. If the working environment temperature of the hydraulic hose is too high or too low, it will inevitably affect the hose's service life and pressure-bearing capacity. Therefore, the hose must be used within its allowable temperature range. For systems where the ambient temperature consistently exceeds this allowable range, it is advisable to use hose protective sleeves or purchase special-purpose hoses. If special chemicals are involved, ensure that the inner and outer surfaces of the hose, the fittings, and the O-ring seals are compatible with the medium. Regarding top connections: nut connections are widely used due to their convenience and low cost; however, under conditions of severe vibration, the issue of nut loosening must be fully considered, in which case flange connections can be considered. Liquid compatibility: The liquid inside the hose must meet the requirements specified in the "Applicable Scope" of the product sample. Exceeding these specifications will compromise the service life and safety of the hose.
Applications of High-Pressure Steel Wire Spiral Hoses:
High-pressure steel wire spiral hoses are suitable for coal mine hydraulic supports and oil and gas field development. They are also applicable to construction engineering, lifting and transportation equipment, metallurgy and forging, mining equipment, marine vessels, injection molding machinery, agricultural machinery, and various types of equipment. They are used in the hydraulic transmission systems of industrial automation and control to transport petroleum-based liquids (such as mineral oils, soluble oils, engine oils, fuel oils, and lubricating oils) and water-based liquids (such as emulsions, oil-water emulsions, and water) under specific pressures and temperatures.
