What are the tips for safe use of hydraulic hoses

High pressure hose is one of the important components in high-pressure water jet systems. From high-pressure water equipment to the nozzle, there is often a distance of tens or even hundreds of meters, with control valves, various joints, etc. in between. The proper use and maintenance of high-pressure hoses can also affect the performance of the cleaning system.

Precautions for using high-pressure hoses

1. When working with high-pressure hoses, the pressure used should not exceed the standard working pressure, otherwise the hose will become excessively fatigued, thereby shortening the service life of the high-pressure pipe;

2. At any time, the curled hose must not be lower than the Z-small bending radius of the hose; Do not bend excessively

3. Safety valves should be used to protect high-pressure water cleaning equipment and hose assemblies;

4. When using safety devices to prevent the joint from being dislodged, consideration should be given to extending or shortening the hose. Because under pressure, the length of the hose will change by ± 2%;

Pressure can affect hose length by ± 2%

5. When cleaning, the hose assembly must not be suspended at high altitude for use. Otherwise, the gravity of the hose will cause the reinforcement layer of the hose to shorten, elongate, and the joints to become excessively fatigued. If necessary, phased bundling should be used;

6. Strictly avoid external forces on the hose assembly, such as:

Do not subject the hose to stress, distortion, compression, or tension;

Do not use heavy objects to move or squeeze on the hose;

Do not subject the hose joint to stress, torque, compression force, or tension;

Do not let the hose fall from a high altitude;

Do not bend hoses on scaffolding;

Do not drag heavy equipment that has already been assembled with hoses.

Do not twist the hose

Prohibit strong bending of pipelines

7. The temperature will affect the anti leakage performance of the hose, so the temperature should be kept below 70 ℃; Avoid approaching heat sources

8. Do not use sewage or water containing sulfides;

9. When the hose assembly is damaged, it should be replaced, such as: worn hose skin, exposed or cut steel wire, chemical damage, corrosion. Enhance layer compression or distortion.

10. It is recommended to protect the metal buckle head (including the interior) with butter during storage to prevent oxidation and corrosion;

11. The inspection cycle for high-pressure hoses is 6 months, and they should be re inspected after 6 months. Only after passing the inspection can they continue to be used;

12. Ensure simple installation, reasonable layout, and proper use; Reasonable application

13. Staff should wear appropriate safety protection products during cleaning operations.

Wear safety protection products

If the high-pressure hose does not work for a long time, it is necessary to drain the accumulated water inside the hose, bend the hose naturally into a roll, and place it horizontally. Proper use or maintenance of high-pressure hoses can prolong their service life, save and reduce unnecessary cost expenditures.
