Standards of hydraulic hose fittings
Crack appear on hydraulic hose
The main reason is that the hose bends in cold weather. If you find cracks on the surface of the hose, you need to check if there are cracks in the inner rubber. While this is to determine if you need to change a new hose. In cold weather, do not move or bend hydraulic hose at will. If you can not avoid that, do it indoors. If it requires long term work in colder condition, choose a high pressure hose that can resist cold.
Bubbles appear on the outer surface of the hose
The reason is that the quality of the hose is not up to standard. Or it is improperly operated during work.
The hose is fine but is leaking a lot of oil
The reason is that when the hose passes through high pressure liquid flow, the inner rubber layer is corroded. While the steel wire layer leaks in a large area. Then it cause a large amount of oil leakage.
Internal rubber layer failure
The inner rubber layer of the hydraulic hose is a key part. It is in direct contact with the hydraulic medium. If the inner rubber layer fails, it will lead to problems such as oil leakage and bulge. The main reasons for the failure of the inner rubber layer include poor quality, improper use, etc.
Reinforce layer failure
The reinforced layer is an important structural layer of the hydraulic hose. Because can protect the integrity of the hose under high pressure. If there is a mechanical failure in the reinforce layer, it will lead to problems. For example, it will shorten service life of the hose. The main reasons for this include poor quality, improper material and harsh use condition.
Mechanical failure at the fracture site
The fracture is the most vulnerable part of the hydraulic hose. If a mechanical failure occurs at the fracture, it will lead to oil leakage and other problems.
