Common failure analysis of each layer of steel wire braided rubber hose时间：2022-03-31浏览次数：259
With the rapid development of science and technology, the quality requirements of steel wire braided hose are higher and higher, which belongs to hydraulic hose. For those who use the hydraulic hose for the first time, the use environment of the hydraulic hose will directly affect its use effect. Hydraulic hoses are generally used in the industrial industry, which is very common, so the demand is basically large.
However, if people do not pay attention to the use environment and use it in a strong acid and alkali environment, the hydraulic hose will naturally be corroded. Or in some high-temperature places, the steel wire braided hose may be melted. Common causes of hydraulic hose failure:
1、 Inner glue layer failure
The obvious expansion of the inner rubber layer may be due to the corrosion of the material of the inner rubber layer by the passing medium, or the temperature exceeds the specified temperature. Therefore, when replacing the hose, it is important to know whether the hose is compounded with the passing medium and whether it can withstand the working temperature. If not, you need to replace the steel wire braided hose with a better quality.
2、 Outer rubber layer failure
When cracks are found in the outer rubber layer, first observe whether there is a problem with the inner rubber layer. If there is no problem with the inner rubber layer, it may be that the outer rubber layer is cut by sharp things, or it is frozen and cracked by severe cold. Therefore, do not move the hose outdoors in a cold environment. If there is a bulge in the outer rubber layer, first check whether it is a quality problem or improper use. Refer to inner glue layer failure.
3、 Enhancement layer failure
The reinforcing layer is mainly woven or wound by steel wires, which are all metal fabrics. If it is corroded, it is easy to rust, which will weaken its strength and cause it to crack under high pressure. This situation is usually accompanied by the cracking and wear of the outer rubber layer. If the joint is broken, it may be because the joint is not tight and moisture enters the reinforcing layer.
The above are the common reasons for the failure of each layer of steel wire braided hose. In the application process, we should pay attention to the abnormalities of the hose to ensure the safety in the use process.
