Precautions for the use of hydraulic hoses and hose assemblies

Jan 06, 2020

Because of the variety of hydraulic hoses, their diverse structures, and the different conditions of use, the service life of hydraulic hoses depends not only on the quality of the hoses, but also on their correct use and maintenance. Therefore, even if the product has a very high quality, if it is not used and maintained properly, it will seriously affect its use quality and life, and even an unexpected serious accident will occur, causing damage to property. The following points for use are provided:

1. Hydraulic hoses and hydraulic hose assemblies can only be used to convey the designed materials, otherwise the service life or failure will be reduced.

2. Use the length of the hydraulic hose correctly. The length of the hydraulic hose changes under high pressure (-4%-+ 2%) and the length changes caused by mechanical movement.

3. Hydraulic hoses and hose assemblies should not be used at pressures (including shock pressures) exceeding the design working pressure.

4. Under normal circumstances, the temperature of the medium conveyed by hydraulic hoses and hose assemblies should not exceed -40 ° C-+ 120 ° C, otherwise the service life will be reduced.

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

6. Hydraulic hoses and hose assemblies should not be used in a twisted state.

7. Hydraulic hoses and hose assemblies should be handled with care, should not be dragged on sharp and rough surfaces, and should not be bent or crushed. 8. Hose and hose assembly should be kept clean, and the inside should be cleaned (especially acid delivery pipe, spray pipe, mortar pipe). Prevent foreign objects from entering the lumen, hinder the transfer of fluid, and damage the equipment.

9. Only after continued use over the service period or shelf life of hydraulic hose and hose assembly to conduct experimental identification.
