Daily Maintenance Of Hydraulic Hose

Thousands of causes of hydraulic hose failures, but with proper precautions, the most common failures can be avoided. The following Industrial Hose Manufacturer will come to tell you a few tips for maintaining hydraulic hoses, and hope to help you.

1. Fluid compatibility

Incompatible fluids will cause deterioration, swelling and delamination of the inner rubber layer of the hose assembly. In some cases, the inner rubber layer may also be partially damaged. The hose must be compatible with the fluid being transferred. Make sure that the fluid is compatible not only 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 hose may cause many tiny cracks due to stale 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 your hose rating is suitable for extremely dry air. For these applications, it is best to choose hoses with PKR or EPDM inner rubber materials.

3. Minimum bending radius

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

4. Wear and tear

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

The above is the daily maintenance method of hydraulic hose introduced by SAE Hydraulic Rubber Hose supplier. Hope to help everyone.
