The outer surface of the hydraulic hoses is exposed to various working environments all the year round, so the outer rubber layer of the hydraulic hoses is the part that is most likely to be damaged by friction and erosion.
Hydraulic oil can be called the "blood" of the hydraulic system. In most cases, the state of the hydraulic oil can detect whether there is a failure in the hydraulic system, so that we can find and solve the problem of the hydraulic system as soon as possible.
The quality of the hydraulic oil basically determines whether the equipment can operate well. Therefore, the replacement of the hydraulic oil becomes an important part of the maintenance of mechanical equipment.
Many people wonder how long the life of hydraulic hoses is, but this is not a fixed number. Generally, when not used and stored reasonably, the lifespan of hydraulic hoses is relatively very long, almost 3-5 years. Of course this varies by hose type and hose manufacturer and use conditions.
For most hydraulic rubber hose assemblies, they can withstand high pressure for a long time, but once damaged, you need to replace them immediately, especially for hydraulic hose joints, Replacing hydraulic hose fittings is also not difficult, you can follow these steps:
The pollutants of the high pressure hydraulic hose mainly come from the lubricating oil, dust, metal or rubber particles generated during the installation and manufacture of the hose. These pollutants are very small, only about 2-5μm, which cannot be observed by the naked eye.
