Several reasons for permanent deformation of PET Self Wrap Braided Sleeve

Because the price of the Cable Sleeve is cheap, the manufacture is simple, the function is reliable, and the installation requirements are simple, it is widely used. Sexual deformation, then the editor will list them one by one for everyone.

1. Factors of compression and stretching of PET Self wrap braided sleeve
Due to the different formulations of PET Self Wrap Braided Sleeve, the compression and stretching of Pet Self Wrap Braided Sleeve produced by different companies are also different. Under long-term compression, the product will produce the imagination of compressive stress relaxation. This phenomenon will gradually expand with time. The longer the time, the smaller the amount of compression and stretching will be, making it less elastic and causing leakage. The direct change method is to increase the cross-sectional size of the product, but it will also lead to an increase in the structure of the product.
2. The relationship between temperature and the relaxation process of PET Self Wrap Braided Sleeve
Temperature is very important to the relaxation degree of PET Self Wrap Braided Sleeve. No matter what kind of rubber material, it will accelerate its aging speed at high temperature. The higher the temperature in the environment, the greater the deformation of the air compression. When the product deformation exceeds 40%, the Cable Sleeve will slowly lose its elastic capacity, causing leakage.
When installing the PET Self Wrap Braided Sleeve, there will be initial stress, which will slowly disappear due to the long-term relaxation of the sleeping seal and the gradual decrease in temperature. In some cases, it may follow the sharp increase in temperature. Even if the rubber material is low temperature resistant, it will not be greater than 25% of the stress generated at 20 degrees. Therefore, when installing the PET Self Wrap Braided Sleeve, the initial stress must be fully considered. The temperature factor in the environment.
3. The effect of medium working pressure on the deformation of PET Self Wrap Braided Sleeve
Compared with the above two factors, the pressure of the medium has a greater impact on the deformation of the PET Self Wrap Braided Sleeve, which is a common situation that causes the deformation of the PET Self Wrap Braided Sleeve in all working conditions. With the modernization of hydraulic pressure With the development of other equipment, the pressure of the hydraulic medium is increasing. The PET Self Wrap Braided Sleeve works in this high-pressure environment for a long time, which will cause permanent deformation of the Cable Sleeve. This deformation is irreversible. Therefore, different materials should be selected for different working pressures, and relatively pressure-resistant rubber materials should be selected. Correspondingly, in order to cope with higher working pressures, the hardness of the sealing ring of pressure-resistant materials will also increase accordingly.
