The inspection and replacement of hydraulic hoses is an important maintenance process to ensure the efficiency and safety of the hydraulic system. The following are the steps for inspecting and replacing hydraulic hoses：
1. Regular inspections. Check the appearance of the hydraulic hose, including whether there are scratches, cracks, deformations, and other damages, as well as whether the hose connections are loose or leaking.
2. Clean the rubber hose. Remove mud, dust, and other debris from the hydraulic hose to prevent internal corrosion and wear.
3. Replacement and judgment. If there are cracks, deformations, or aging in the hydraulic hose, it should be replaced in a timely manner. Common signs of aging include hardening, cracking, etc; When replacing hydraulic hoses, products that meet specifications and quality requirements should be selected.
4. Determine the replacement time. It is generally recommended to inspect hydraulic hoses at least once a year and determine whether replacement is necessary based on their usage and condition; When used in extreme environments, the replacement cycle may be shorter.
5. Disassemble the old rubber hose. Before replacement, it is necessary to remove the old rubber hose, which usually involves releasing pressure from the hydraulic system and using appropriate tools to remove the joint.
6. Select a new hose. When selecting a new rubber hose, factors such as pipeline material (such as styrene butadiene rubber, chloroprene rubber, etc.), size, wall thickness, etc. should be considered to ensure that it is suitable for working conditions and media.
7. Install a new rubber hose. Before installing a new rubber hose, it is necessary to clean the inside of the pipeline and connect it with a dedicated connector to ensure that the pipeline is clean and free of impurities.
8. Testing and inspection. After installation, perform a leak test and pressure test on the hydraulic system to ensure that it operates normally without any leakage, distortion, or other issues.
9. Maintenance and recording. Regularly inspect the status of hydraulic hoses, promptly identify and address potential issues, record information such as the date and model of hose replacement, for subsequent maintenance and management.
In addition, when replacing hydraulic hoses, attention should also be paid to using the correct tools to avoid damaging pipelines and other accessories, and to ensure that the pipeline connectors are completely sealed to avoid leakage.
