Common failures of hydraulic hoses include the following:
1. Appearance of the hose crack: the main reason is the hose in cold environment bending. If you find a crack in the appearance of the hose, you need to pay attention to see if there are cracks in the hose adhesive, to determine whether the need to immediately replace the hose. In the cold environment, do not move or bend the hydraulic hose, if necessary, indoor. If you need to work in a cold environment for a long time, use a cold hose.
2. Air bubbles on the outer surface of the hose: the hose is not up to standard or is improperly operated.
3. Hose is not damaged but a lot of oil leakage: because the hose through the high-pressure fluid flow, the inner rubber was corroded scratch, until the steel wire layer caused a large area of oil leakage.
4. Serious deterioration of the hose outer adhesive layer, the surface slightly cracked: this is the hose natural aging performance, due to aging deterioration, the outer layer of oxidation, so that its surface covered with a layer of ozone, over time will thicken, the hose should be replaced at this point.
5. Failure of internal rubber layer: the inner rubber layer is the key part of the hydraulic hose, it directly contact the hydraulic media, if the inner rubber layer failure, will lead to hose performance decline, a large number of oil leakage, bulging and other problems. The main reasons for the failure of inner adhesive layer are poor production quality, improper selection, wrong installation, improper use, etc. .
6. Reinforced layer mechanical failure: reinforced layer is an important structural layer of hydraulic hose, it can protect the integrity of hose under high pressure. If mechanical failure occurs in the strengthening layer, it will lead to the decline of the pressure resistance and shorten the service life of the hose. The main causes of mechanical failure of strengthening layer are poor production quality, improper selection of materials, poor use environment and so on.
7. Mechanical failure at the fracture: the fracture is the most vulnerable part of the hydraulic hose, if there is a mechanical failure at the fracture, will lead to hose fracture, oil leakage and other problems. The main causes of mechanical failure at the fracture are poor production quality, improper selection of materials, poor use environment and so on.
The above is the hydraulic hose common fault and cause analysis, for these faults, we should take appropriate preventive measures and solutions to ensure the normal operation of the hydraulic system.
