5/8 inch EN856-4SH wire spiral hydraulic hose
Before we delve into EN 856-4SH | MSHA | MA wire-wound hydraulic hose, we first need to have a clear understanding of this professional term and the technical characteristics behind it. As an indispensable component in the industrial field, hydraulic hoses undertake the key task of transmitting power and media, and the wire-wound hydraulic hoses under the EN 856-4SH | MSHA | MA standards have become the first choice in many industries with their excellent performance and wide range of applications.
I. Standards and certifications: quality assurance
EN 856-4SH is one of the hydraulic hose standards formulated by the European Committee for Standardization (CEN), focusing on standardizing the design, manufacturing and testing requirements of hydraulic hoses to ensure their safety, reliability and durability during use. MSHA (Mine Safety and Health Administration) and MA (Mine Approval) are safety certifications for mining equipment, which means that the hose not only meets general industrial standards, but also passes more stringent mining safety reviews, and can operate stably in extreme and harsh mining environments.
II. Structural analysis: the source of strength
The reason why EN 856-4SH | MSHA | MA wire-wound hydraulic hose can withstand high pressure, high temperature and harsh working conditions is due to its carefully designed multi-layer structure. The inner rubber layer is made of black oil-resistant synthetic rubber, which can not only effectively resist the erosion of hydraulic oil, but also has good sealing and elasticity, ensuring that the medium does not leak during transmission. The reinforcement layer is made of four layers of high-strength steel wire tightly wound, which is the core of the hose to withstand high pressure, ensuring that the hose can still maintain a stable shape and performance under extreme conditions. The outer rubber layer is also made of black oil-resistant and weather-resistant synthetic rubber, which not only protects the internal structure from damage by the external environment, but also provides additional wear resistance and anti-aging performance.
III. Application range: wide and diverse
Thanks to its excellent performance characteristics, EN 856-4SH | MSHA | MA wire-wound hydraulic hose is widely used in various industrial fields. Whether it is conveying water-based, petroleum-based or biodegradable hydraulic oil, this hose can easily cope with it and meet the media transmission needs under different working conditions. We often see it in industries such as heavy machinery, oil extraction, mining operations, agricultural irrigation, and chemical production. Especially in the depths of mines, facing complex and changeable geological conditions and harsh working environments, this hose has become an important part of ensuring the normal operation of equipment and improving production efficiency with its excellent pressure resistance, temperature resistance, and wear resistance.
IV. Technical features and advantages
1. High pressure bearing capacity: The four-layer high-strength steel wire winding reinforcement layer enables the hose to withstand extremely high working pressure and ensure the stability of medium transmission.
2. Oil and temperature resistance: The inner and outer rubber layers are made of oil-resistant and weather-resistant synthetic rubber, which can maintain stable performance in a wide temperature range (-40°C to +100°C) and resist the erosion of hydraulic oil.
3. Wear and aging resistance: The special formula of the outer rubber layer gives the hose good wear resistance and aging resistance, extending its service life.
4. Flexibility and adaptability: The hose has good bending performance and certain elasticity, and can adapt to various complex installation and working environments.
