Will a Concrete Hose Age After a Certain Time
Oil-resistant hose refers to a rubber hose with oil-resistant properties. It has good tolerance to oil substances such as gasoline and diesel. Therefore, it can work in an oil environment for a long time. Oil-resistant hoses are generally made of nitrile material. Because nitrile rubber is the most oil-resistant among general-purpose rubbers. It is widely used in automobiles, engineering machinery and other equipment. So how to maintain the hose to extend its service life?
For hoses that are frequently used under severe impact pressure, there may be a problem of bursting. Analyzing the reasons, we can find that this is often not because the hose is subjected to too much static pressure, but because the material transported by the hose is too fast because of the operation speed. This makes the pressure shock intensity and frequency too large, which will cause this problem.
During the operation of automobiles, engineering machinery and other equipment, the material conveying pressure of the oil pipe will also change. This frequent pressure change causes the hose to receive frequent impact force. Trying to work in this environment may cause rapid aging of the hose, causing the hose to rupture or bubble. Finally, the hose becomes loose or even falls off.
How to maintain oil-resistant hoses
So when we operate the equipment, we should pull the valve rod gently and slowly, and not too hard or too fast.
For hoses that work too long in high temperature environments
Long-term high temperature environments accelerate the oxidation reaction between oxygen and rubber. In other words, high temperature accelerates the aging of hoses. A lot of heat is released during the operation of mechanical equipment. For example, the hydraulic system will cause the oil to heat up due to power failure when it is working. In addition, the temperature outside the equipment will also cause the temperature of materials such as oil in the equipment to rise rapidly. The increase in the temperature of oil materials accelerates the aging of hoses. This reduces the elasticity and sealing of oil-resistant hoses, which will eventually lead to accidents.
