How to solve the problem of outer rubber layer of PET Braided Sleeve

1. The PET Braided Sleeve is not ruptured but a large amount of oil leaks. If the hose is not ruptured but a large amount of oil leaks, the reason is that when the high-pressure liquid flow passes through the hose, the inner rubber is eroded and scratched until the steel wire layer leaks out in a large area. Extensive oil seepage. This fault generally occurs at the bend of the pipeline. The hose should be checked and replaced, and the bending radius of the hose should meet the technical requirements during use. 4. The outer rubber layer of the Braided Sleeve has seriously deteriorated, and micro-cracks appear on the surface. This is a sign of the natural aging of the Braided Sleeve after being used for too long. Due to aging and deterioration, the outer layer is continuously oxidized, causing the surface layer to become brittle. As time goes by, the brittle layer deepens, and the Braided Sleeve only needs to be slightly bent during use.

2. Bubbling appears on the surface of the Braided Sleeve
① Bubbles appear on the surface of PET braided sleeve because the quality of the Braided Sleeve is substandard or improper use. If bubbles appear in the middle of the Braided Sleeve, it is mostly a quality problem in the production of the Braided Sleeve, and qualified Pet Braided Sleeve should be replaced in time; if bubbles appear at the joints of the PET Braided Sleeve, it is most likely due to improper installation of the joints.
② Steel wire braiding, winding Braided Sleeve joints and Braided Sleeve connection ends are available in detachable and buckled styles. The detachable joint jacket and joint core have a hexagonal shape. The outer wall of the joint core is conical, making it easy to disassemble and assemble the Braided Sleeve. . After the joint core is connected to the nut, insert the steel wire to prevent loosening.
③The crimped Braided Sleeve joint is composed of a joint jacket and a joint core. During assembly, the outer rubber layer needs to be peeled off, inserted into the joint core head, the joint jacket tightened, and then crimped with a mold on special equipment to allow the Braided Sleeve to obtain a certain amount of compression. to achieve a tight connection.

3. Cracks appear on the surface of PET Braided Sleeve
① PET Braided Sleeve In cold environments, cracks on the surface of the Braided Sleeve will cause the Braided Sleeve to bend. If cracks are found on the outside of the Braided Sleeve, pay attention to whether there are cracks in the inner rubber of the Braided Sleeve and decide whether to replace the Braided Sleeve immediately.
② Do not move the Braided Sleeve or dismantle or repair the hydraulic system at will in a cold environment. If necessary, it should be done indoors. If you need to work in a colder environment for a long time, you should replace the cold-resistant Braided Sleeve.
