What Should be Paid Attention To in The Maintenance of Hydraulic Hoses

There are many reasons for hydraulic hose failure, but the most common failures can be avoided by taking proper precautions. The following Hydraulic Hose Manufacturer will introduce you to the points to pay attention to in the process of using hydraulic hoses, I hope it will help you.

1. Fluid compatibility

Incompatible liquids can cause deterioration, swelling and delamination of the internal rubber layer of the hose assembly. In some cases, the internal rubber layer may also be partially damaged. The hose must be compatible with the fluid to be transported. Ensure that the fluid is not only compatible with the inner rubber layer, but also with the outer rubber layer, joints and even O-rings.

2. Dry air/stale air

The inner rubber layer of the Hydraulic Hose may cause many small cracks due to old or dry air. Sometimes this type of failure is difficult to detect because the hose can still remain flexible, but there are signs of external leakage.

To avoid dry or stale air problems, you should confirm that the hose rating is suitable for extremely dry air. For these applications, it is best to choose a hose with PKR or EPDM internal rubber material.

3. Minimum bending radius

If the minimum bend radius is not reached, the Hydraulic Rubber Hose assembly may fail relatively quickly. In vacuum or suction applications, if the bending radius is exceeded, the hose may flatten in the bending area. This will hinder or restrict the flow of media. If the bending is too severe, the hose may be kinked. To prevent malfunction of the minimum bend radius hose, the recommended bend radius should be carefully checked.

4. Wear

Hydraulic hoses are exposed to harsh environments every day, and their effects will eventually appear on the hoses. If inspected irregularly, wear and tear may cause the hose assembly to rupture and leak. Excessive friction between the hose and an external object or even another hose will wear down the coating on the hose and eventually wear the reinforcement. A correctly assembled and installed hose will have a longer service life, thereby reducing downtime and maintenance costs.
