How to extend the service life of hydraulic hose?

First, what is hydraulic hose

Hydraulic hose, also known as hydraulic hose, hydraulic tubing, is used to transport a certain pressure and temperature of the liquid rubber pipe, mainly used in mine hydraulic support, oil field development, suitable for engineering construction, lifting and transportation, metallurgy and forging, mining equipment, ships, injection molding machinery, agricultural machinery, various machine tools and various industrial departments mechanized, automated hydraulic system.

Second, how many years is the service life of the hydraulic hose

Hydraulic hose is mainly used in hydraulic system, can be used for a long time, under normal use conditions, good quality hydraulic hose used for more than ten or twenty years is no problem, in actual work as long as the rubber of the hydraulic tubing skin does not crack out, no oil leakage, generally do not need to be replaced.

However, it should be noted that the service life of the hydraulic hose will be affected by the conditions of use, improper use may lead to greatly shortened service life, should be regularly checked in the use of the hose assembly whether there is leakage, kinks, outer rubber layer blistering, abrasion, wear or other damage, if there is assembly damage or wear, need to be replaced immediately.

Third, how to extend the service life of hydraulic hose

The service life of the hydraulic hose is not only determined by the quality, but also by the correct use, if not properly used and maintained, it will seriously affect the quality and life of its use, and even the occurrence of unwarranted serious accidents, to extend the service life of the hydraulic hose, the main attention:

1, hydraulic hose and hose assembly can only be used to transport the designed material, otherwise it will reduce the service life or failure.

2, the correct use of the length of the hydraulic hose, the length of the hydraulic hose changes under high pressure (-4%-+2%) and the length change caused by mechanical movement.

3, the hydraulic hose and hose assembly should not be used in excess of the design working pressure (including impact pressure).

4, the hydraulic hose and hose assembly delivered by the medium temperature under normal circumstances, should not exceed -40℃-+120℃, otherwise it will reduce the service life.

5, the hydraulic hose and hose assembly should not be used under the minimum bending radius of the hose, to avoid bending or bending near the pipe connection, otherwise it will hinder the hydraulic transmission and delivery of materials or damage the hose assembly.

6, hydraulic hose and hose assembly, should not be used in the torsion state.

7, the hydraulic hose and hose assembly should be carefully handled, should not be dragged on sharp and rough surfaces, should not be bent and flattened.

8, hydraulic hose and hose assembly should be kept clean, the inside should be washed clean (especially acid pipe, spray pipe, mortar pipe). Prevent foreign objects from entering the cavity, impeding fluid delivery, and damaging the equipment.

9, exceed the service period or storage period of the hydraulic hose and hose assembly to be tested and identified before continuing to use.
