Hose maintenance

Hose maintenance.

Hose and connector maintenance procedures can reduce downtime and maintain operational performance of the hydraulic system. The following are maintenance considerations

1. Hose assemblies must be checked at a regular frequency based on the equipment's previous history, complete maintenance/inspection procedures and the rigor and potential hazards required for use.

2. To reduce the risk of personal injury, do not touch the hose assemblies during the system test. Pay attention to potential danger areas near the hose assemblies.

Test hoses and connectors are as follows:

1. Exposed, damaged or corroded steel wire

2. Leaks of pipes and joints

3. Broken, damaged or corroded joints

4. Other obvious signs of damage

If the above situation occurs, the hose assembly should be replaced immediatel

The hydraulic system should also be tested as follows:

1. Leak the port

2. Pipe clamp to protect or protect system damage or leakage

3. There is too much dust or oil on the components

4. System fluid condition, fluid temperature, pollution and air retention

If any of the above is found, appropriate and correct action shall be taken

Functional tests should be performed to determine whether the system is leak free and operating correctly

1. If the hose assembly can be tested and separated from the hydraulic system, further steps can be taken to ensure proper maintenance of the assembly

2. After the hose assembly is separated, blow and wash with clean compressed air or rinse with a clean solution medium.

3. Test the cut, residue, and cleanliness of the glue in the hose

4. Check the straightness of the hose and ensure that the hose is not twisted

5. Ensure that joints are in good condition and properly buckled or assembled on assemblies

If the above situation is found, the hose assembly should be replaced

Hose assemblies shall be hydrostatic tested in accordance with the approved test stand and procedure outlined in SAEJ517 for 30 seconds to 1 minute at test pressure or twice the hose working pressure.

When the test pressure is reached, visually inspect the hose for damage or leakage, or the body of the pipe indicating loose joints compared to signs of joint movement.In any case, the components should be replaced.Specific seam replacement intervals must be based on early service life, government and factory recommendations, otherwise damage will result in personal injury or property loss.

Pipe storage

Temperature, humidity, ozone, direct sunlight, oils, solvents, corrosive liquids, insects;Rodents and radioactive materials can both pose a hazard to hose products, leading to premature hose failure.Hoses should be stored in a dark, dry environment away from heat sources, electrical equipment and hazardous elements mentioned above.The ideal storage temperature of the hose is +10°C to +20°C with a high temperature of 38°C
