Structure of four layer steel wire reinforced hydraulic hose

 

In the field of engineering construction, the performance of hydraulic systems directly affects the efficiency and safety of mechanical equipment. As a key component in hydraulic systems, the performance of hydraulic hoses will directly affect the smooth progress of engineering operations. This article will focus on introducing the four layer steel wire reinforced hydraulic hose, especially the characteristics and advantages of DN25 caliber and 70MPa burst pressure.

 

1、 Basic concepts of hydraulic hoses

 

Hydraulic hose is a flexible pipeline used for transporting hydraulic oil or other liquid media. Its main function is to transmit hydraulic power, enabling mechanical equipment to operate effectively. The material, structure, and performance of hydraulic hoses will affect their scope of application and service life. Among numerous hydraulic hoses, four layer steel wire reinforced hydraulic hoses are widely used in various construction machinery, including excavators, loaders, etc., due to their excellent compressive and wear resistance.

 

2、 Structure of four layer steel wire reinforced hydraulic hose

 

The structural design of a four layer steel wire reinforced hydraulic hose is the key to achieving high-pressure conveying. The basic structure of this type of hose includes the following levels:

 

1. Inner layer: It is usually made of wear-resistant and oil resistant synthetic rubber material, which can effectively prevent liquid leakage and corrosion, ensuring the stability of high-performance liquid parts.

 

2. Middle layer: On the outside of the inner layer, there is a layer of steel wire reinforced mesh, which is woven from high-strength steel wire and has extremely strong tensile strength and stiffness. This level ensures that hydraulic hoses will not expand or deform under high pressure conditions.

 

3. Outer layer: The outer layer is made of wear-resistant, cold resistant, and high-temperature resistant rubber material, which not only protects the inner layer from external environmental damage, but also has good flexibility, making it easy to operate under various complex conditions.

 

4. Steel wire ring layer: In some applications, a second layer of steel wire reinforcement mesh may be added to enhance its blast resistance and ensure the safety of the hose even under harsh working conditions.

 

3、 Detailed explanation of product parameters

 

The application range and performance of the DN25 caliber four layer steel wire reinforced hydraulic hose are also impressive. The following are the main product parameters:

 

-Caliber: DN25, suitable for hydraulic systems with a diameter of 25 millimeters, this caliber can be widely used in various hydraulic equipment.

 

-Burst pressure: up to 70MPa, which is a burst pressure of 700 bar, is sufficient to meet the hydraulic requirements of most construction machinery, ensuring the stability and safety of the equipment.

 

-Temperature range: This hose can withstand temperature changes from -40 ° C to+100 ° C and is suitable for various climatic conditions and high temperature and cold working environments.

 

-Flexibility: Although the structure is sturdy, the hose itself has good flexibility, making it easy to install and operate.

 

4、 Advantages of Four Layer Steel Wire Reinforced Hydraulic Hose

 

1. High compressive strength

 

The design of the four layer steel wire enables this hydraulic hose to maintain safe operation under conditions of up to 70MPa, reducing potential risks during high-pressure operations and greatly improving work safety.

 

2. Wear resistance and corrosion resistance

 

The engineering site environment is complex and dusty, and hydraulic hoses are susceptible to wear and chemical corrosion. High quality material selection, combined with steel wire reinforced design, enables it to perform well in harsh environments and effectively extend its service life.

 

3. Multi purpose adaptability

 

This four layer steel wire reinforced hydraulic hose is not only suitable for construction machinery, but also for various fields such as agricultural machinery, mining equipment, ships, etc. It has strong adaptability and greatly expands its application scenarios.

 

4. Easy installation

 

Due to its excellent flexibility, this hose has less difficulty in installation, which can reduce labor costs and improve installation efficiency.

 

5. High cost-effectiveness

 

Although the initial investment may be slightly high, considering its durability and low maintenance costs, in the long run, the four layer steel wire reinforced hydraulic hose has a high cost-effectiveness and is an ideal choice for various engineering equipment.

 

5、 Application Cases

 

In practical applications, four layer steel wire reinforced hydraulic hoses have been adopted by multiple well-known brands of construction machinery. For example, in a large construction project, the hydraulic system of the excavator needs to frequently lift heavy objects, and traditional hoses often leak oil or even burst, resulting in project delays. After using this hydraulic hose, the project proceeded smoothly, achieving efficient operation and demonstrating its excellent performance in practical operation.

 

6、 Maintenance and Maintenance Suggestions

 

Although the four layer steel wire reinforced hydraulic hose has high durability and safety, regular maintenance and upkeep are still essential. Here are a few suggestions:

 

1. Regular inspection: The appearance of hydraulic hoses should be regularly checked for cuts, aging, or deformation, and any problematic hoses should be replaced in a timely manner.

 

2. Cleaning and Protection: During maintenance, specialized cleaning agents can be used to clean the hoses and apply protective coatings to enhance the protective effect of their outer layer.

 

3. Avoid high temperature exposure: When not in use, try to avoid exposing the hose to high temperatures or direct sunlight to avoid affecting its service life.

 

4. Reasonable storage: When storing hydraulic hoses, they should be placed in a dry and ventilated environment to avoid heavy objects pressing on the hoses and prevent deformation.

 

7、 Summary

 

Overall, the DN25 caliber and 70MPa burst pressure of the four layer steel wire reinforced hydraulic hose are indispensable high-performance products in the field of construction machinery. With its excellent compressive strength, wear resistance, and wide range of applications, it provides strong guarantees for the efficient operation of modern construction machinery. With the help of high-quality hydraulic hoses, the smooth implementation of engineering projects can be achieved, greatly improving the efficiency of engineering equipment.

 

Whether in construction, agriculture, or industrial production, investing in a high-quality four layer steel wire reinforced hydraulic hose will undoubtedly save costs, improve production efficiency, and help enterprises stand undefeated in market competition.
