Oil resistant hose refers to rubber hose with oil resistant properties. It is not only used in automobiles, engineering machinery and other equipment, but also plays an indispensable supporting role. It has a good tolerance to gasoline, diesel oil and other oil substances, can work for a long time in the oil environment. The oil resistant hose is generally made of nitrile material, which is not only because nitrile rubber is a general rubber with good oil resistance, but also has good wear resistance, air tightness and aging resistance. So how to maintain the hose to prolong its working life?

First, let’s analyze the factors that affect the working life of the hose.

1. The pressure impact intensity frequency is too large

There may be a burst problem for oil resistant hose after a period of frequent use under severe shock pressure. Analysis of the reasons we can find that this is often not because the hose bears too much static pressure, but because the material delivered by the hose because the operation speed is too fast, so that the pressure impact strength and frequency is too large, will lead to this problem.

2. Frequent pressure leads to loosening and shedding

In the operation process of automobiles, construction machinery and other equipment, the material conveying pressure of the hose will also change with it, and this frequent pressure change will lead to the frequent impact effect of the hose. Try to work in this environment, may lead to the rapid aging of the hose, the hose rupture or blister, and then make the hose loose or even fall off the fault.

So, how to maintain resistant tubing?

1. Gently pull the lever of the valve

When we operate the automobile, construction machinery and other equipment, we should gently and gently pull the lever of the valve, not too hard and too fast.

2. Take cooling measures

Oil resistance hose for extended working hours in high temperature environments. Long time of high temperature environment, accelerate the oxidation reaction of oxygen and rubber, that is to say, high temperature accelerates the aging of rubber hose. During the operation of mechanical equipment, parts will release a lot of heat, for example, the hydraulic system will let the oil heat because of power failure. In addition, the temperature outside the equipment will also lead to a rapid rise in the temperature of oil and other materials in the equipment. The temperature and height of oil materials accelerate the oxidation reaction of the hose, that is to say, accelerate the aging, so that the elastic table of tubing resistance, sealing, will eventually lead to the occurrence of accidents. So in the operation of the equipment, when the internal temperature of the equipment rises sharply, we should find out the cause of the problem in time, especially when working for a long time in the summer, we should be alert to the occurrence of accidents, and cooling measures can be taken when necessary.

The above is for everyone to explain how to use and maintain the oil resistant hose, I hope to be helpful to you.
