When we discuss the topic of "EN 857SC Wire Braided Hydraulic Hose" in depth, we have to first realize that this type of hose is an important part of the hydraulic system, and its performance and quality are directly related to the operating efficiency and safety of the entire system. EN 857, as a standard developed by the European Committee for Standardization (CEN), provides strict specifications and guidance for the design, production and testing of wire braided hydraulic hoses.
I. Background and significance of EN 857SC standard
The introduction of EN 857SC standard aims to unify and improve the manufacturing level of hydraulic hose industry and ensure the interchangeability and reliability of products worldwide. With the rapid development of industrial automation, hydraulic systems are widely used in engineering machinery, agricultural machinery, petrochemical industry, aerospace and other fields, and the requirements for hydraulic hoses are becoming increasingly stringent. Therefore, the implementation of EN 857 standard not only promotes technological innovation and industrial upgrading, but also provides users with safer, more efficient and economical choices.
II. Structure and characteristics of steel wire braided hydraulic hose
The steel wire braided hydraulic hose under the EN 857 standard is mainly composed of an inner rubber layer, a reinforcement layer (steel wire braided layer), an outer rubber layer and possible additional layers (such as wear-resistant layer and corrosion-resistant layer). This unique structural design gives the hose a series of excellent performance characteristics:
1. High-pressure bearing capacity: The steel wire braided layer as a reinforcement layer can effectively disperse and withstand the high pressure in the pipe, ensuring that the hose can still maintain stable operation under high-pressure environment.
2. Wear and corrosion resistance: The outer rubber layer is usually made of wear-resistant and corrosion-resistant materials, which effectively resists the erosion of the external environment to the hose and prolongs its service life.
3. Good flexibility: The reasonable structural design enables the hose to maintain strength while still having good bending performance, which is convenient for installation and use under complex working conditions.
4. Anti-pulse shock: The steel wire braided layer can effectively absorb the pulse shock in the hydraulic system and protect the system from damage.
5. High sealing: The inner rubber layer and the joint are connected by a special process to ensure high sealing at the hose connection and prevent oil leakage.
III. Classification and application under EN 857 standard
EN 857 standard is divided into multiple series according to the different uses and performance requirements of hoses, such as 1SC, 2SC, 4SP, etc. Each series has its specific application scenarios and advantages:
1SC series application: suitable for medium and low pressure hydraulic systems, such as agricultural irrigation, municipal engineering and other fields, and is favored for its economy and good versatility.
2SC series application: compared with the 1SC series, it has higher pressure bearing capacity and better wear resistance, and is suitable for heavy industrial fields such as engineering machinery and metallurgical equipment.
4SP series application: as a high-performance hydraulic hose, the 4SP series has become the first choice for high-end fields such as aerospace and deep-sea exploration with its excellent pressure resistance, pulse impact resistance and excellent flexibility.
IV. Purchase and installation precautions
When purchasing EN 857 steel wire braided hydraulic hose, users need to carefully consider the working pressure, medium type, working environment and other factors of the hose according to actual needs to ensure that the selected hose meets the system requirements. At the same time, during the installation process, the operating procedures should be strictly followed to ensure that the hose is firmly connected and sealed reliably to avoid safety hazards caused by improper installation.
V. Maintenance and care
To ensure the long-term and stable operation of EN 857 steel wire braided hydraulic hose, regular maintenance and care are essential.
