Hydraulic hose assemblies are used widely throughout manufacturing industry – for everything from car brakes to pumping stations, and so on, and so on. Over time, even a well-maintained hose will wear out, making it necessary to be repaired or replaced.
The life expectancy of every hydraulic hose assembly defers and depends on multiple factors, including environmental conditions. Here are some “signs” that it is time to repair or replace your hydraulic hose.
Repeated oil leaks are a common sign that it is time to have your hydraulic hose replaced. However, it is good to make sure whether it is not a repairable problem. For example, a damaged O-ring might be the cause for the oil leakage. In this case you will only need to replace the O-ring, instead of the entire hose assembly.
Improper connection (for instance, when the connection is overtightened) could be another cause of oil leakage. Therefore, check your hose assemblies on a regular basis, but if everything looks fine and you are still experiencing oil leakage, it is likely time to repair your hydraulic hose assembly.
Outer Cover Damage
Over time it is normal to expect small scuffs and scrapes on the hydraulic hoses. In most of the cases you should not neglect them because external damage to the hose cover can cause your hose to fail due to reinforcement deterioration.
Exposed hose reinforcement
The hydraulic hose construction consists of a reinforcement (steel, textile, etc.) designed to provide added flexibility and durability. After a while under daily use, the external cover of the hose will wear out and you will start to see the internal reinforcement. This is an absolute indication that your hose should be replaced.
Twisting and Bending of the Hose
A hose that is twisted or has an incorrect bending radius can be dangerous for you or for the others around you due to the pressure that might build up. The liquids going through a hydraulic hose should flow freely. In case the hose is bent or twisted in a way that prevents this from happening, you run the risk of the hose bursting and causing oil leakage. If you notice that the hose is improperly twisted or bent, it is best to go ahead and replace it.
Hydraulic Hose Maintenance
It is highly recommended to carry out a preventative maintenance of the hydraulic hoses in your system. This will save you costs and time in the future, because in most cases the replacement of your old hydraulic hose with a new one will be less expensive compared to a repair of your entire equipment.
Always make sure that the hydraulic hose assembly is mounted properly, otherwise an improperly mounted assembly can cause the hose to whip around with a lot of force and cause injuries. Regularly check your cooling system and pressure regulators to ensure they are working properly.
Clean oil leakages immediately, because even a small leak can make the floors slippery and dangerous.
In addition, do not neglect other hydraulic components, such as pumps and motors, because they can affect the proper functioning of the entire system.
Conducting a monthly inspection as well as replacement of your hose assemblies every 1-2-3 years (depending on the degree of wear) is an effective way to keep things running smoothly. Always take into consideration that some hoses last longer, while others should be replaced or repaired each year or even more often.
