Understanding China EN853 2SN Standards and Applications of Hydraulic Hose

In the realm of hydraulic systems, the components used are crucial to ensuring efficiency, durability, and safety. One such critical component is the hydraulic hose, which serves the purpose of conveying hydraulic fluid. When discussing hydraulic hoses, the China EN853 2SN standard becomes particularly relevant. This article delves into what the China EN853 2SN standard entails, its specifications, applications, and the importance of adhering to such standards.

What is the China EN853 2SN Standard?

The EN853 2SN is a standard that specifies the construction and performance requirements for high-pressure hydraulic rubber hoses. It is adopted by various countries, including China, and is crucial for ensuring that hoses can withstand the pressures and conditions typical in hydraulic systems. The 2SN designation indicates a specific type of hose construction, referring to a two-wire braided hose suitable for high-pressure applications.

Specifications of EN853 2SN

The EN853 2SN standard outlines the following key specifications

1. Design and Construction The 2SN hoses are constructed with an inner tube made of synthetic rubber that is resistant to hydraulic fluid. This is then reinforced with two layers of steel wire braids, which enhances the hose's strength and pressure resistance.

2. Temperature Range The hose is designed to operate efficiently within a temperature range of -40°C to +100°C (-40°F to +212°F), making it suitable for various environments.

3. Pressure Ratings EN853 2SN hoses are typically rated for working pressures ranging from 130 to 400 bar (approximately 1885 to 5800 psi), depending on the internal diameter of the hose. This makes them ideal for high-pressure applications.

4. Sizes Available The standard accommodates various hose sizes, from small diameters suited for compact machinery to larger sizes for industrial applications.

5. Fluid Compatibility These hoses are suitable for hydraulic fluids, water, and water-based fluids, making them versatile for multiple industries.

Given its robust construction and high-pressure capabilities, the EN853 2SN hydraulic hose finds applications across various industries, including

- Construction Heavy machinery utilized in construction often requires hydraulic systems to operate. EN853 2SN hoses are integral in ensuring that equipment such as excavators, cranes, and bulldozers function smoothly.

- Agriculture Tractors and other agricultural equipment use hydraulic hoses to operate various attachments and mechanisms. The 2SN hoses provide the reliability needed in demanding farm operations.

- Mining In the mining industry, where high pressure is necessary for equipment operation and fluid transport, the EN853 2SN hoses are commonly employed.

- Manufacturing Many manufacturing processes utilize hydraulics for automation and machinery operation. The reliability of these hoses is vital for maintaining production efficiency.

Importance of Compliance with Standards

Adherence to the EN853 2SN standard is essential for several reasons. Firstly, it ensures that the hoses can withstand the intended operating conditions, reducing the risk of failures that can lead to costly downtimes and safety hazards. Secondly, compliance helps maintain consistency in quality across different manufacturers, which is vital for users who may source hoses from various suppliers. Lastly, using hoses that meet recognized standards can enhance the credibility of businesses, showcasing their commitment to quality and safety.

Conclusion

The China EN853 2SN standard represents a crucial element in the hydraulic systems industry. With its specifications designed for high-pressure environments, the 2SN hose is versatile and applicable across numerous sectors. As industries continue to evolve and demand higher performance from their hydraulic systems, the importance of standards like EN853 cannot be overstated. By ensuring that machinery operates safely and efficiently with compliant components, businesses can achieve better productivity and enhanced safety in their operations.
