Rubber Hydraulic Hose is an important part of the hydraulic system of construction machinery such as concrete trucks, road rollers, excavators, loaders, etc. There are often leakage, cracks, ruptures, loosening and other faults in use, but people often ignore these problems and continue to use them. , This not only wastes hydraulic oil, pollutes the environment, but also affects work efficiency, and even causes accidents, endangering human-machine safety.
So, when does your hydraulic hose need to be replaced?
Damage of cover
In a cold environment, cracks on the surface of the hydraulic hose will cause the hose to be bent. Therefore, in a cold environment, do not move the hose or repair the hydraulic system at will. If necessary, it should be done indoors. If the surface of the hose is found to be cracked and it needs to work in a cold environment for a long time, replace the hose immediately.
In addition, due to aging and deterioration, the outer layer is continuously oxidized to make the surface layer become brittle. With the extension of time, the brittle layer deepens. As long as the hose is slightly bent during use, micro cracks will occur. In this case, the hose should also be replaced.We recommend Orientflex low temperature resistant and aging resistant hydraulic hoses.
Damage of the inner rubber layer
Due to the addition of plasticizes to rubber products, the hose is flexible and plastic. The hose works under high temperature and high pressure, and the hose overheats, which will cause the plasticizes to overflow. In addition, when the superheated oil passes through the cylinders, valves or other components in the system, if a large pressure drop occurs, the oil will decompose, causing the inner layer of the hose to oxidize and harden. In this case, the hose should be replaced in time. We recommend Orientflex oil-resistant hydraulic hoses.
Damage of the reinforcement layer
If the hose is broken, peel off the outer rubber layer and check that the reinforcement layer is not rusted, but there are irregular broken wires in the length direction of the reinforcement layer. The main reason is that the hose is subjected to high-frequency impact force. For hoses that are often subjected to high-frequency shocks, we recommend Orientflex hoses with steel wire wound skeletons as reinforcement layers.
