WHAT MAINTENANCE PRACTICES EXTEND THE LIFE OF HYDRAULIC HOSES?

The correct use and maintenance methods can extend the service life of the hose and hydraulics, including regular inspection and replacement of the hose and hydraulics, avoid excessive bending, and keep the hose and hydraulics clean.

Hydraulics hoses are widely used in industrial production, and their role is to transport hydraulic oil to the power system of the machine or equipment. Due to the complexity and pressure of the use environment, damage or leakage of the hose and hydraulics may cause production failure and loss of life and property. In order to use the hose and hydraulics correctly and extend its life, the following are several effective methods.Implementing a robust maintenance program for hose and hydraulics is essential to ensure their longevity and the overall reliability of the hydraulic system. Here’s a detailed look at the maintenance practices you mentioned, along with some additional tips:

1. Regular Inspections

- Frequency: Conduct visual inspections at least every few months, or more frequently if the system operates in harsh conditions.

- What to Check For:

- External Damage: Look for cuts, abrasions, bulges, and leaks.

- Internal Damage: Signs of internal damage may include soft spots, hardening, or discoloration.

- Connections: Ensure all fittings and connections are tight and secure.

- Routing: Verify that hose and hydraulics are not rubbing against other components or sharp edges.

- Documentation: Keep records of inspections to track the condition of hoses over time and identify trends.

2. Cleaning

- Importance: Dirt and debris can accumulate on the exterior of hose and hydraulics, leading to premature wear and potential damage.

Methods:

- Dry Brushing: Use a soft-bristled brush to remove loose dirt and debris.

- Water Washing: Rinse hose and hydraulics with clean water to remove stubborn dirt. Avoid high-pressure washers, as they can damage the hose and hydraulics cover.

- Chemical Cleaning: If necessary, use mild, non-corrosive cleaning agents. Always rinse thoroughly with water afterward.

- Avoid Harsh Chemicals: Strong solvents and acids can degrade the hose material, leading to premature failure.

3. Pressure Monitoring

- Importance: Excessive pressure can cause hose and hydraulics to burst or fail, leading to costly repairs and potential safety hazards.

Methods:

- Gauges: Install pressure gauges at critical points in the system to monitor pressure continuously.

- Alarms: Set up alarms to alert operators when pressure exceeds safe limits.

- Data Logging: Use data loggers to record pressure readings over time, helping to identify trends and potential issues.

- Regular Checks: Perform routine checks to ensure gauges are functioning correctly and are calibrated.

4. Scheduled Replacements

- Importance: Even with proper maintenance, hose and hydraulics will eventually wear out and need to be replaced.

Factors to Consider:

- Usage: Frequent or heavy use may require more frequent replacements.

- Environmental Conditions: Exposure to extreme temperatures, chemicals, or UV light can accelerate hose degradation.

- Hose Age: Some manufacturers provide guidelines for the expected lifespan of their hoses.

Preventive Maintenance Schedule:

- Develop a Plan: Create a schedule that includes regular replacement intervals based on the above factors.

- Inspection Records: Use inspection records to adjust the replacement schedule as needed.

- Spares Inventory: Maintain an inventory of critical hose and hydraulics to minimize downtime during replacements.

Additional Tips

- Training: Ensure that all operators and maintenance personnel are trained in proper hose and hydraulics handling and inspection techniques.

- Storage: Store spare hose and hydraulics in a cool, dry place away from direct sunlight and sources of heat.

- Documentation: Keep detailed records of all maintenance activities, including inspections, cleanings, and replacements, to facilitate troubleshooting and future maintenance planning.

By following these maintenance practices, you can significantly extend the life of your hose and hydraulics, reduce the risk of unexpected failures, and ensure the efficient operation of your hydraulic system.
