Why Hydraulic Maintenance and Flushing Are Crucial

Contaminated fluid in a hydraulic system is the primary culprit behind system failures. Before introducing new major components, your hydraulic system must be free of contaminants. Simply changing the filter element and fluid won’t suffice to thoroughly clean the system.

Hydraulic Flushing: The Key to Peak Performance

As hydraulic systems age, particulates can accumulate in the hydraulic fluid, wreaking havoc on pumps, motors, valves, cylinders, and other critical hydraulic components. This accumulation can lead to costly repairs and reduced operational efficiency. Delta Hydraulics & Service offers a hydraulic flushing service that ensures your hydraulic systems function at their absolute best.

Our hydraulic flushing service is designed to address routine maintenance, repairs to an existing hydraulic system, or flushing for a newly built system. We possess the hydraulic flushing equipment, filters, and expertise to exert the correct pressures to flush your hydraulic system to meet your engineering standards.

Delta Hydraulics & Service also provides a range of hydraulic flushing equipment for rent, ensuring your maintenance team has access to the tools they need. We offer guidance on setup and training, as well as recommendations for the best filters for your specific flushing requirements.

Filtration: Restoring Fluid to Peak Condition

Delta Hydraulics’ filtration systems are your solution for saving valuable dollars and getting the most life out of your hydraulic fluids. By restoring fluid to the recommended ISO cleanliness level, you can extend the lifespan of your equipment. Our trained technicians use particle counters to monitor fluid cleanliness during filtration, ensuring the filtration levels meet your engineering standards. Contaminated hydraulic systems are breeding grounds for major component failure and unnecessary expenses. We eliminate contamination, ensuring your system operates smoothly.

Preventive Maintenance: The Cost-Effective Approach

Preventative maintenance, through proactive flushing, offers a cost-effective alternative to emergency procedures, costly upgrades, or system modifications. By adopting these practices, you can keep your hydraulic system in excellent condition, minimize downtime, and extend the lifespan of your equipment.

Expert Tips for Hydraulic Equipment Maintenance

Hydraulic systems are the powerhouses behind heavy lifting, excavation, and precision maneuvers in various industries. To ensure the longevity and dependable performance of hydraulic equipment, prioritizing regular maintenance is paramount. Routine inspection and cleaning, monitoring fluid levels and quality, maintaining proper fluid temperatures, lubrication and seal maintenance, regular filter replacement, and optimizing system pressure settings—all these steps are integral to keeping your hydraulic system in prime condition. They not only minimize downtime but also significantly extend the lifespan of your equipment. Below, we outline the best practices for maintaining hydraulic systems in construction equipment, helping you achieve peak performance while minimizing downtime.

1. Regular Inspections:

  • Conduct routine inspections of your hydraulic system to identify potential issues.
  • Look for signs of leaks, loose connections, damaged hoses, or wear and tear.
  • Schedule inspections at specified intervals or as recommended by the equipment manufacturer.

2. Monitor Fluid Levels and Quality:

  • Hydraulic fluid is the lifeblood of your system; check fluid levels frequently, following the manufacturer’s guidelines.
  • Low fluid levels can lead to cavitation and insufficient lubrication, resulting in premature wear and decreased performance.
  • Regularly test the fluid for contamination, moisture, and degradation, replacing it as needed.
  • Perform fluid analysis to detect contaminants like water, dirt, or metal particles that can harm the system’s components.

3. Maintain Proper Fluid Temperatures:

  • Hydraulic systems generate heat during operation, and excessive temperatures can cause fluid breakdown and component failure.
  • Monitor the system’s operating temperature regularly to ensure it stays within the recommended range.
  • Consider using coolers or heat exchangers if temperatures exceed acceptable limits.
  • Promote adequate ventilation and airflow around hydraulic components to dissipate heat effectively.

4. Lubrication and Seal Maintenance:

  • Proper lubrication is essential to reduce friction and wear within hydraulic equipment.
  • Adhere to the manufacturer’s guidelines for lubricating moving parts like cylinders, pistons, and bearings.
  • Lubricate seals and O-rings to prevent leakage and maintain their integrity.
  • Confirm that lubricants are compatible with the hydraulic fluid and the system’s components before application.

5. Regular Filter Replacement:

  • Filters play a pivotal role in hydraulic maintenance by trapping contaminants and preventing their circulation within the system.
  • Filters can become clogged over time, reducing effectiveness and compromising system performance.
  • Replace filters at recommended intervals per the manufacturer’s guidance or based on usage conditions.
  • Periodically inspect and clean or replace filters to ensure unhindered flow, optimal system efficiency, and the prevention of damage to hydraulic components.

6. Maintain System Pressure and Optimize Settings:

  • Proper pressure settings are critical for the operation of your hydraulic equipment.
  • Continuously monitor and adjust pressure levels according to the manufacturer’s recommendations.
  • Excessive pressure can damage components, while insufficient pressure results in subpar performance.
  • Regularly inspect and calibrate pressure relief valves to ensure precise and consistent pressure control.

By diligently following these maintenance practices, you can keep your hydraulic system in excellent condition, reduce downtime, and extend the lifespan of your equipment. These proactive measures ensure your hydraulic systems remain reliable and cost-effective assets.
