High pressure steel wire braided rubber hoses play an important role in engineering machinery and hydraulic systems, as they are responsible for transmitting high-pressure liquids or gases and are key components to ensure stable system operation. However, in practical application, high-pressure steel wire braided rubber hoses face enormous pressure challenges, and any minor structural damage can lead to serious consequences. Therefore, ensuring that the rubber hose has no structural damage during use is an important prerequisite for ensuring system safety and improving work efficiency.

1、 Structure and Characteristics

High pressure steel wire braided rubber hoses are usually composed of multiple layers, including an inner rubber layer, a middle rubber layer, a steel wire braided reinforcement layer, and an outer rubber layer. The inner rubber layer is in direct contact with high-pressure liquid and is often made of oil resistant and wear-resistant synthetic rubber materials to ensure good sealing and corrosion resistance. The middle adhesive layer serves as a transition layer, strengthening the connection between the inner and outer layers and buffering pressure. The steel wire braided reinforcement layer is the core of the rubber hose, which is made up of multiple layers of high-strength steel wires interwoven together, providing the hose with strong compressive and burst resistance. The outer adhesive layer is responsible for protecting the internal structure, resisting erosion and mechanical damage from the external environment.

2、 The pressure challenge during the application process

In construction machinery and hydraulic systems, high-pressure steel wire braided rubber hoses need to withstand enormous pressure from liquids, which not only persists but also undergoes rapid changes under certain operating conditions. For example, in heavy equipment such as excavators and loaders, the pressure of hydraulic systems often reaches tens or even hundreds of megapascals, which puts high demands on the pressure bearing capacity and structural stability of rubber hoses. In addition, frequent starting, stopping, and turning operations can also cause pressure fluctuations within the system, further exacerbating the pressure load on the hose.

3、 Risk and impact of structural damage

Once structural damage such as cracks, bulging, delamination, etc. occurs in high-pressure steel wire braided rubber hoses, it will seriously affect their pressure bearing capacity and service life. Specifically, structural damage may lead to the following risks and impacts:

1. Reduced pressure bearing capacity: Structural damage can weaken the load-bearing capacity of the hose, causing it to rupture at lower pressures and affecting the normal operation of the system.

2. Sealing performance failure: Damage to the inner adhesive layer or joints may lead to liquid leakage, which not only wastes resources but also may cause environmental pollution and safety hazards.

3. System performance degradation: After the hose is damaged, the response speed and efficiency of the hydraulic system will be affected, reducing the overall operational performance and stability of the machine.

4. Increased maintenance costs: Frequent replacement and repair of rubber hoses will increase the operational and time costs of the enterprise.

4、 Measures to ensure no structural damage

To ensure that the high-pressure steel wire braided rubber hose is not structurally damaged during use, the following measures need to be taken:

1. Choose high-quality rubber hoses: When purchasing rubber hoses, it is recommended to choose high-quality products produced by reputable manufacturers to ensure uniform wall thickness, sufficient steel wire weaving layers, excellent air tightness and pressure resistance.

2. Standardized installation and connection: When installing rubber hoses, it is necessary to strictly follow the operating procedures to ensure a tight and reliable connection between the joint and the hose, avoiding loosening or detachment. At the same time, appropriate clamping amount and clamping speed should be selected to avoid excessive damage to the hose.

3. Regular inspection and maintenance: Regularly inspect the rubber hose to promptly detect and address damage such as cracks and swelling. For rubber hoses that are severely aged and worn, they should be replaced in a timely manner to avoid safety accidents.

4. Reasonably control working pressure: According to the design requirements of the hydraulic system, control the working pressure reasonably to avoid damage to the hose caused by overpressure operation.

5. Improve working environment: Try to avoid exposing rubber hoses to high temperature, humidity, and highly corrosive environments to reduce damage from external factors.

As a key component in hydraulic systems, the structural integrity and pressure bearing capacity of high-pressure steel wire braided rubber hoses are directly related to the safety and stable operation of the system. Therefore, it is necessary to attach great importance to the protection and maintenance of the rubber hose during use to ensure that no structural damage occurs. By implementing measures such as selecting high-quality products, standardized installation and connection, regular inspection and maintenance, and reasonable control of working pressure, the service life of rubber hoses can be effectively extended, and the overall performance and reliability of the system can be improved.
