Steel wire braided rubber hoseMade of unique styrene butadiene rubber, it is tightly bonded, soft and suitable, with small deformation under pressure, and has good acid and alkali resistance, high temperature resistance, and aging resistance. Rolling bearings have high single pulse working pressure, good compressive strength, and fatigue relief level.

Steel wire braided rubber hoses can be used for conveying in hydraulic systems of construction machinery to disperse working pressure. The inner layer of adhesive has the function of carrying transmission materials and protecting stainless steel wires from corrosion, while the outer layer of adhesive protects stainless steel wires from damage. The stainless steel wire layer is a skeleton material that plays a role in improvement.

1、 Microstructure

The inner layer can apply pressure to the conveyed material to ensure that the stainless steel wire is not corroded. The outer rubber layer protects the cable from damage, and the cable (0.3-2.0 reinforced cable) layer is a reinforced skeleton material. Styrene butadiene rubber is made from nitrile rubber, which has good wear resistance, and is combined with a unique enhancer. As an inner plastic layer, it has tight adhesion, soft applicability, minimal stress deformation, bending resistance, and wear resistance. The outer plastic layer is made of unique styrene butadiene rubber, which is a fiber material with a higher relative density than ordinary plastics, and therefore has wear resistance.

2、 Factors affecting the service life of rubber hoses

Although steel wire braided rubber hoses have a long service life, improper use can also affect their service life.

1. Pressure matching

When using and selecting, it is necessary to consider the working pressure. If the working pressure exceeds 1.25 times the specified pressure, the service life will be reduced by 50%. The pressure fluctuations during the working process also have a significant impact on the service life of the hose. When it is opened and closed, it can cause fluctuations in fluid pressure, increasing the pressure. When making a purchase, it should be chosen based on 1.5 times the actual working intensity, which can greatly extend its service life.

2. Path matching

When equipping hydraulic hoses, the selection should be based on the requirements of use, as changes in the inner diameter of the pipeline can cause work impact and system imbalance. If a hydraulic hose with a diameter of 4 mm is used instead of the specified hydraulic hose with a diameter of 5 mm, the service life will be reduced by 3/1.

3. Avoid bending

When using, bending should be avoided as much as possible. If bending is required during use, the bending radius should be avoided from being too small. A too small bending radius will compress the internal steel wire and affect its service life.

The above is the structure of steel wire braided rubber hoses and the factors that affect their lifespan. Purchasing rubber hoses is to meet application needs, and attention should be paid to quality issues when purchasing.
