A hydraulic hose is an indispensable component of the hydraulic system, which undertakes the important task of conveying a hydraulic medium. However, the life of hydraulic hoses is a key issue, which directly affects the reliability and safety of the hydraulic system. This article will discuss the life of hydraulic hose, and explore its influencing factors and methods to extend its life.

First, let's take a look at the basic structure of hydraulic hose. A hydraulic hose is usually composed of the inner tube, reinforcement layer, and outer tube. The inner tube is the part in direct contact with the hydraulic medium, usually made of rubber or plastic, with good oil resistance and wear resistance. The reinforcement layer is set to increase the strength and pressure resistance of the hose. Common reinforcement layer materials are steel wire braided layer and steel wire spiral layer. The outer tube is to protect the inner tube and reinforcement layer from damage by the external environment, usually made of rubber or plastic.

The life of a hydraulic hose is affected by many factors. The first is working pressure. The hydraulic hose is under great pressure during operation. If it exceeds the bearing capacity of the hose, it will cause the hose to rupture or leak. Therefore, it is crucial to correctly select the appropriate working pressure range to extend the life of the hydraulic hose.

The second is the working temperature. The hydraulic system generates heat during operation. If the temperature is too high, it will cause the hose material to age, harden, and become brittle, thereby reducing the life of the hose. Therefore, it is important to reasonably control the working temperature of the hydraulic system and select high-temperature resistant hose materials to extend the life of the hydraulic hose.

In addition, the bending radius of the hydraulic hose will also affect its life. When the hydraulic hose is over-bent, it will cause excessive stress on the reinforcement layer inside the hose, thereby damaging the hose structure. Therefore, when installing and using the hydraulic hose, care should be taken to avoid excessive bending and select a suitable bending radius to reduce fatigue damage to the hose.

In addition, the use environment of the hydraulic hose will also have an impact on its life. For example, if the hose is exposed to ultraviolet rays for a long time, it will cause the outer layer of the hose to age and crack; if the hose is exposed to chemicals, it will cause corrosion and damage to the hose material. Therefore, when selecting hydraulic hoses, the appropriate hose material should be selected according to the specific use environment, and corresponding protective measures should be taken to extend the service life of the hose.

In order to extend the life of the hydraulic hose, we can use the following methods. The first is to regularly inspect and maintain the hydraulic hose. Regularly check the appearance of the hose for cracks, deformation, or wear, and replace the damaged hose in time to prevent the hose from malfunctioning during operation. The second is to use the hydraulic system correctly. Avoid adverse working conditions such as overload, excessive bending, and high temperature to reduce fatigue damage of the hose. The last is to choose high-quality hydraulic hoses. Choosing hose materials with good oil resistance, wear resistance, and high-temperature resistance can increase the service life of the hose.

In summary, the life of the hydraulic hose is an important factor in the reliability and safety of the hydraulic system. By correctly selecting the working pressure, controlling the working temperature, avoiding excessive bending, and selecting high-quality hose materials, the service life of the hydraulic hose can be extended and the performance and reliability of the hydraulic system can be improved. Therefore, when designing, installing, and maintaining the hydraulic system, attention should be paid to the life of the hydraulic hose to ensure the normal operation and safety of the system.
