Essential Hydraulic Pump Maintenance Tips for Reliable Performance

Hydraulic systems are extremely useful when it comes to working with heavy loads or operating machinery. Unfortunately, when hydraulic systems malfunction or are damaged, they can also be extremely expensive. The expense to repair the system can be quite costly, but damaged systems also mean extensive downtime and missed work, which affects your bottom line. To ensure that your hydraulic pump remains efficient and in operation, it is important to have a regular maintenance program.

So, what does maintaining your hydraulic system mean and how do you do it?

To maintain your system, you need to regularly monitor every component for wear, damage, excessive pressure or heat, and contaminants. In this article, we will go over some tips on what to look for and how to preserve your hydraulic system to ensure it will meet your needs for many years.

Monitor the Fluid

Hydraulic fluid is the lifeblood of a hydraulic system; it is what transfers power, lubricates components, and transfers heat and contamination. Without well-functioning and uncontaminated hydraulic fluid, your system and the entire machine will not perform efficiently. Here are some tips to get the most out of your fluid.

• • Make sure the fluid is topped off. Hydraulic fluid that is too low allows air into the reservoir which affects the available pressure.
  • Monitor the fluid for contaminants such as water, dirt, or metal shavings
  • When filling the fluid, clean the reservoir opening and opening of the fluid jug to ensure that no debris inadvertently fall in.
  • Regularly check and change hydraulic filters.
  • Monitor your fluid and system temperature. Fluid that is too hot causes oxidation while fluid that is too cool causes condensation and possible cavitation, both of which can damage the entire system.
  • Consult your manufacturer for the proper temperature range.
  • Test your fluid for suspicious odors or color.

Inspect Components

Over time and continual use, hydraulic components can become damaged, frayed, or worn down. Visually and auditorily inspect components on a regular basis to ensure worn out parts are properly addressed and replaced so they do not affect the entire system.

Below are some tips on what to look for:

• • Listen to your system. High-pitched whining or knocking sounds could indicate cavitation which is gas bubbles causing small implosions in the hydraulic fluid. This creates unnecessary wear and damage to the hydraulic pump and should be addressed immediately.
  • Check hoses and tubing for any kinks, frays, or other damage. Hose damage can restrict fluid movement or cause leakage.
  • Inspect breather filters and caps for holes, damage, or contamination.
  • Make sure couplers and fittings are clean to ensure there is no contamination.
  • Check pipes, fittings, and any other metal component for rust or dents.
  • Check the thickness of hydraulic lines as this could indicate a buildup of pressure.
  • Replace seals if you suspect they may be damaged or worn out as damaged seals can cause leakage and a loss of pressure.
  • Replace filters regularly.
  • Use an infrared thermometer to monitor the temperature of the electric drive motor to ensure it is not overheating.
  • Monitor for leaks.

Conclusion

While this is not a comprehensive list of everything that you should regularly monitor on your hydraulic pump, it is a good starting point. The best advice is to create a schedule for yourself and your team for hydraulic maintenance. Use a checklist to ensure that each component is working efficiently and is not damaged or worn. Be sure to check with the hydraulic manufacturer for a complete maintenance list to ensure the efficiency and longevity of your hydraulic system.
