Hydraulic pump uses hose to pass hydraulic oil. Hose assembly for engineering machinery and coal mines EN856
In modern engineering machinery and coal mine operations, hydraulic pumps are the core components of power transmission. The stability and reliability of their performance are directly related to the efficiency and safety of the entire operating system. The connection between the hydraulic pump and the hydraulic system often relies on high-quality hose assemblies, especially hose assemblies that meet the EN856 standard. This article will discuss in detail the importance, technical characteristics and application advantages of the hose assembly EN856 for engineering machinery and coal mines when the hydraulic pump uses a hose to pass hydraulic oil from three aspects.
1. The importance of EN856 hose assembly
In the operating environment of engineering machinery and coal mines, hydraulic pumps need to continuously and stably deliver high-pressure hydraulic oil to each actuator to drive the normal operation of the equipment. In this process, the quality and performance of the hose assembly as a transmission channel for hydraulic oil are crucial.
Withstand high pressure and impact: When engineering machinery and coal mine equipment are working, the hydraulic oil output by the hydraulic pump often has a high pressure, and is also affected by vibration and impact from the equipment. The hose assembly of EN856 standard can effectively withstand high pressure and impact by adopting multi-layer steel wire winding or braiding structure, ensuring the stable transmission of hydraulic oil.
Wear and corrosion resistance: In harsh environments such as coal mines, hose assemblies must also have good wear and corrosion resistance. The hose assembly of EN856 standard usually uses high-quality rubber materials and undergoes special treatment to maintain a long service life in harsh environments.
Adapt to complex working conditions: The working environment of construction machinery and coal mining equipment is often complex and changeable, and the hose assembly needs to be able to adapt to various bending, torsion and stretching conditions. The hose assembly of EN856 standard has excellent flexibility and elasticity, which can meet the use requirements under complex working conditions.
2. Technical characteristics of EN856 hose assembly
The EN856 standard is a technical specification formulated by Europe for hydraulic hose assemblies. It specifies in detail the requirements for the structure, materials, performance and other aspects of the hose assembly. Hose assemblies that meet the EN856 standard usually have the following technical characteristics:
Multi-layer wire winding structure: EN856 standard hose assemblies usually adopt multi-layer wire winding structure to enhance their pressure bearing capacity and impact resistance. This structure allows the hose assembly to maintain a stable shape under high pressure and is not prone to deformation or rupture.
High-quality rubber lining: The lining of the hose assembly is usually made of high-quality rubber material with good sealing and wear resistance. This can ensure that the hydraulic oil will not leak during the transmission process, while reducing the wear of the inner wall of the hose and extending the service life.
High-strength outer coating: In order to enhance the wear resistance and anti-aging performance of the hose assembly, the EN856 standard stipulates that the hose assembly should have a high-strength outer coating. This outer coating is usually made of wear-resistant and corrosion-resistant materials, which can effectively protect the hose assembly from damage from the external environment.
Flexible joint design: The joint part of the hose assembly of the EN856 standard usually adopts flexible connection methods, such as crimping type, threaded type, etc. This ensures that the hose assembly can be quickly and easily installed and removed when connected, while maintaining good sealing performance.
3. Application advantages of EN856 hose assembly
In construction machinery and coal mining operations, the use of hose assemblies that meet the EN856 standard has significant application advantages:
Improve operating efficiency: Since the hose assembly that meets the EN856 standard has excellent pressure bearing capacity and impact resistance, it can ensure that the hydraulic oil output by the hydraulic pump is stably and quickly transmitted to each actuator. This can significantly improve the operating efficiency of the equipment and shorten the operating cycle.
Reduce maintenance costs: The hose assembly that meets the EN856 standard has a long service life and is not prone to failures such as leakage or rupture. This can reduce the downtime and maintenance times of the equipment, thereby reducing maintenance costs.
Enhance operational safety: In dangerous environments such as coal mines, the use of high-quality hose assemblies can ensure the stable operation of the hydraulic system and avoid safety accidents caused by failures such as hose rupture or leakage. At the same time, the hose assembly that meets the EN856 standard also has excellent wear and corrosion resistance, and can maintain a long service life in harsh environments, further enhancing the safety of operations.
Adapt to various working conditions: The working environment of construction machinery and coal mining equipment is often complex and changeable. The hose assembly of EN856 standard has excellent flexibility and elasticity, and can adapt to various working conditions such as bending, torsion and stretching. This enables the hose assembly to maintain stable performance under various complex working conditions and ensure the normal operation of the equipment.
In addition, with the continuous advancement of technology and the continuous development of the market, the hose assembly of EN856 standard is also constantly undergoing technical upgrades and product innovations. For example, some manufacturers have begun to use new materials and technologies to manufacture hose assemblies to improve their pressure bearing capacity, wear resistance and anti-aging performance. The application of these innovative technologies will further promote the widespread application and development of hose assemblies of EN856 standard in construction machinery and coal mining operations.
In summary, when the hydraulic pump uses a hose to pass hydraulic oil, the hose assembly EN856 for construction machinery and coal mining has significant importance and application advantages. By using hose assemblies that meet the EN856 standard, it is possible to ensure that the hydraulic oil output by the hydraulic pump is stably and quickly transmitted to each actuator, thereby improving the operating efficiency of the equipment; at the same time, it can also reduce maintenance costs, enhance operational safety, and adapt to a variety of working conditions. Therefore, in engineering machinery and coal mining operations, hose assemblies that meet the EN856 standard should be widely promoted and used to promote the sustainable development and progress of the industry.
