Having hydraulic systems down costs money, both in terms of repairs and lost productivity. Regular preventative maintenance is crucial for keeping your equipment running smoothly and avoiding unexpected breakdowns.

1. Keep Hydraulic Fluid Clean and Contaminant Free

One of the most critical aspects of maintaining hydraulic systems is ensuring the hydraulic fluid remains clean and free of contaminants. Contaminants such as dirt, water, and air cause significant damage to the system, leading to wear and tear on components, and ultimately, system failure.

  • Regular Fluid Checks: Routinely check the fluid levels and quality. Look for signs of contamination, such as discoloration or cloudiness.

  • Use Proper Filtration: Invest in high-quality filters and change them regularly to prevent contaminants from circulating through the system.

  • Seal Integrity: Inspect seals regularly to ensure they are not allowing contaminants into the system. Replace any damaged or worn seals promptly.

2. Inspect Hoses and Connections

Hoses and connections are vital components of hydraulic systems, but they are prone to wear and damage over time. Regular inspections help catch issues before they become major problems.

  • Check for Leaks: Leaks are a common issue with hydraulic systems. Inspect hoses and connections regularly for signs of leaks, such as oil drips or wet spots.

  • Look for Wear and Tear: Examine hoses for signs of wear, cracking, or bulging. Replace any hoses that show signs of damage.

  • Ensure Proper Fit: Make sure all connections are tight and secure to prevent leaks and ensure optimal system performance.

3. Monitor System Pressure and Temperature

Hydraulic systems rely on precise pressure and temperature control to operate effectively. Deviations from normal operating conditions indicate potential issues that need to be addressed.

  • Install Gauges: Use pressure and temperature gauges to monitor the system’s operating conditions regularly.

  • Set Alarms: Consider installing alarms to notify you when pressure or temperature levels are outside the normal range.

  • Troubleshoot Promptly: If you notice any irregularities, troubleshoot the system immediately to prevent further damage.

4. Regularly Test Hydraulic Fluid

Hydraulic fluid testing is an essential part of preventative maintenance. By analyzing the fluid, you can detect early signs of wear, contamination, and other issues that could lead to system failure.

  • Conduct Routine Testing: Test the hydraulic fluid at regular intervals to monitor its condition.

  • Analyze for Contaminants: Look for signs of water, air, and particulate contamination, as well as chemical degradation of the fluid.

  • Take Action Based on Results: If the test results indicate contamination or fluid degradation, take corrective action immediately, such as replacing the fluid or addressing the source of contamination.

5. Create and Follow a Maintenance Schedule

The best way to ensure hydraulic systems receive the care they needs is to create and follow a detailed maintenance schedule. This schedule should include all the routine checks and maintenance tasks necessary to keep your system running smoothly.

  • Customize Your Schedule: Tailor the maintenance schedule to your specific equipment and usage patterns.

  • Include All Essential Tasks: Ensure that the schedule covers all critical maintenance tasks, including fluid checks, hose inspections, and system monitoring.

  • Stick to the Plan: Adhere to the maintenance schedule diligently to prevent small issues from becoming major problems.
