Proper maintenance of hydraulic reservoirs is crucial for the smooth operation and longevity of your equipment. Manual cleaning and flushing are essential parts of this process. Regular cleaning helps prevent operational issues and ensures that your system performs efficiently over time. If you're looking to maintain or restore the performance of your hydraulic system, here's a step-by-step guide on how to clean a hydraulic reservoir effectively. Following these steps will help you keep your system in top condition and extend its lifespan. Contact Us Start by draining the hydraulic system while the fluid is still warm. This makes it easier to remove all the old fluid. As you drain, check for any signs of contamination, such as water or debris, and pay attention to accumulators, cylinders, and filters. If the fluid appears cloudy or has water mixed in, use desiccant air to flush out the moisture. Replace the reservoir’s filters at this stage to ensure clean fluid flow. Use a lint-free cloth to wipe down the inside of the reservoir. Remove any loose paint, dirt, or sludge that may have accumulated. Be thorough but gentle to avoid damaging the internal surfaces. Once the reservoir is clean, flush it with a low-viscosity fluid—ideally one that is compatible with your system. You can also use a specialized hydraulic cleaning solvent if needed. Flush the system in a turbulent manner to dislodge any remaining particles. Afterward, drain the reservoir quickly and replace the filters again for better efficiency. Fill the reservoir about three-quarters full and run the pump for 15 seconds, then turn it off for 45 seconds. Repeat this cycle three times. This helps purge air from the system and ensures proper circulation. Run the pump for one minute with the pressure valve open, then let it rest. Repeat this a couple of times, making sure not to run the pump for more than five minutes at a time. Lift the relief valve to check for any residual contaminants before letting the system rest for another five minutes. Operate each actuator individually, ensuring that the fluid returns to the reservoir after each cycle. Shut the system down after each actuator and let it sit. Keep an eye on the fluid level and refill it to about 50% to maintain stability. Refill the reservoir to 75% capacity and run the system in five-minute intervals. After each interval, release any trapped air from the system. Let the system run continuously for 30 minutes before replacing the filters once more. Check for any signs of cross-contamination and replace the filters if necessary to ensure clean fluid flow. After cleaning, run the system for no more than six hours initially. This allows you to monitor the system’s performance without risking damage. Replace the filters one last time and test a fluid sample to confirm everything is running smoothly. With a bit of practice, you'll be able to teach others how to properly clean a hydraulic system. Finishing Systems is a leading provider of finishing systems across the country.
