How many years is the service life of hydraulic hose?

Hydraulic hose is a hose used in hydraulic system, also known as hydraulic hose. It has a long service life. Under normal use, a good quality hydraulic hose can be used for more than ten or twenty years. In addition to the product quality, the service life of hydraulic hose is also affected by the service conditions. If used improperly, its service life will be greatly shortened. Therefore, attention should be paid to the correct use to prolong the service life of liquid oxygen. Let's take a look at how to extend the service life of hydraulic hoses. What is a hydraulic hose?

Hydraulic hose, also known as hydraulic hose and hydraulic oil hose, is a kind of rubber hose used to transport liquid with certain pressure and temperature. It is mainly used for mine hydraulic support and oilfield development, and is suitable for mechanized and automatic hydraulic systems in engineering construction, lifting and transportation, metallurgical forging, mining equipment, ships, injection molding machinery, agricultural machinery, various machine tools and various industrial departments.

2. How many years is the service life of the hydraulic hose?

Hydraulic hoses are mainly used in hydraulic systems and can be used for a long time. Generally speaking, under normal use, good quality hydraulic hoses can be used for more than ten or twenty years without problems. In practical work, as long as the rubber on the surface of the hydraulic hose does not crack and leak oil, it generally does not need to be replaced.

However, it should be noted that the service life of the hydraulic hose will be affected by the service conditions. Improper use may greatly shorten the service life. Hose components in use should be inspected regularly for leakage, kinking, blistering, abrasion or other damage. If the components are damaged or worn, they need to be replaced immediately.

Third, how to prolong the service life of hydraulic hoses

The service life of hydraulic hose depends not only on its quality, but also on its correct use. If it cannot be used and maintained correctly, it will seriously affect its service quality and service life, and even cause undue serious accidents. In order to prolong the service life of hydraulic hoses, the key points are as follows:

1, the hydraulic hose and hose assembly can only be used to transport the designed materials, otherwise the service life will be shortened or it will fail.

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

3. The hydraulic hose and hose assembly should not be used under the pressure exceeding the design working pressure (including impact pressure).

4. Under normal circumstances, the temperature of the medium conveyed by the hydraulic hose and hose assembly cannot exceed -40℃-+ 120℃, otherwise the service life will be shortened.

5. Hydraulic hoses and hose assemblies should not be used under the minimum bending radius of hoses, so as to avoid bending or warping near the pipe joints, otherwise it will hinder hydraulic transmission and transportation of materials or damage hose assemblies.

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

7. Hydraulic hoses and hose assemblies should be handled with care, and should not be dragged on sharp and rough surfaces, bent or flattened.

8. The hydraulic hoses and hose assemblies shall be kept clean, and the interior shall be washed clean (especially the acid conveying pipes, spray pipes and mortar pipes). Prevent foreign matter from entering the lumen, hinder liquid transportation and damage the equipment.

9. Hydraulic hoses and hose assemblies that have exceeded their service life or storage life can only be used after test and appraisal.
