What is the working principle of hydraulic hose spring sheath?

1. Protective function:
The main function of the hydraulic hose spring sheath is to protect the hydraulic hose from external physical damage. In industrial environments, hoses may be scratched by sharp objects, crushed by heavy objects, or rub against other components during movement. The spring sheath provides a sturdy protective barrier for the hose through the elasticity and strength of its metal material. This protection not only prevents the hose from being cut or worn, but also prevents the hose from breaking when impacted. The design of a spring sleeve typically allows the hose to move freely within a certain range without causing additional pressure or damage to the hose itself.

2. Absorption of impact:
Hydraulic hoses may be subjected to various impacts and pressures during operation, which may cause hose rupture or leakage. The design of the spring sheath enables it to absorb and disperse these impact forces, thereby reducing direct damage to the hose. The metal coil structure of the spring sheath can deform upon impact, absorb energy, and then return to its original state after the impact. This elastic property makes the spring sheath a very effective impact absorbing device.

3. Prevent wear and tear:
In hydraulic systems, hoses may experience friction with other components during movement, resulting in surface wear of the hoses. Wear and tear not only shortens the service life of hoses, but may also lead to hose leaks. The spring sheath reduces the chance of the hose coming into contact with other hard objects by forming a protective layer on the outside of the hose, effectively preventing wear and tear. The surface of the spring sheath is usually smooth, which also helps reduce friction.

4. Resistance to environmental factors:
When working outdoors or in specific environments, hydraulic hoses may be susceptible to corrosion from ultraviolet radiation, chemicals, oil stains, and other environmental factors. These factors may accelerate the aging of hose materials, leading to a decrease in hose performance. The spring sheath can provide an additional layer of protection for the hose, preventing these environmental factors from directly affecting the surface of the hose. Some high-quality spring sleeves may also use special materials or coatings to provide additional chemical corrosion resistance and UV resistance.

5. Extend service life:
By reducing the physical damage and environmental erosion of hoses, spring sleeves help extend the service life of hoses. The damage of hoses is usually caused by external factors such as wear, impact, environmental erosion, etc. The spring sheath reduces the impact of these factors on the hose by providing an additional protective layer, thereby extending the service life of the hose. Spring sleeves can also reduce the maintenance cost of hoses, as well protected hoses do not require frequent replacement.

6. Easy to install and maintain:
The design of hydraulic hose spring sleeves usually takes into account the convenience of installation and maintenance. Many spring sleeves can be easily fitted onto hoses without the need for special tools or techniques. This design allows even non professionals to quickly install and replace the spring guard. The maintenance of the spring sheath is relatively simple, usually only requiring regular checks on the integrity and fastening of the sheath to ensure that it continues to provide protection for the hose.

7. Improve security:
In some applications, hydraulic hoses may rupture due to high pressure or other reasons, causing liquid splashing, which may pose a danger to operators and equipment. The spring sheath can serve as a safety device to reduce the risk of liquid splashing when the hose ruptures. In the event of a hose rupture, the spring sleeve can temporarily maintain the shape of the hose, preventing immediate liquid leakage and providing valuable time for operators to shut down the system and take measures to prevent further damage.

8. Adaptability:
The hydraulic hose spring sheath can be designed to accommodate hoses of different diameters and lengths, as well as different working environments and conditions. This adaptability enables the spring sheath to be widely used in various hydraulic systems, whether indoors or outdoors, and whether in high or low temperature environments. The spring sheath can also be customized according to specific application requirements.
