Oil Sampling: To confirm your suspicions, you decide to take a sample of the hydraulic oil. You collect a small amount of oil from the reservoir and send it to the lab for analysis.

Lab Analysis: The lab analysis report reveals that the hydraulic oil contains various contaminants such as dirt particles, water, and even tiny metal fragments from wear and tear. These contaminants can lead to reduced system efficiency, increased wear on components, and potentially system failure if not addressed.

Filtration Decision: Based on the lab report, you decide that the hydraulic oil needs thorough filtration to remove the contaminants. You choose a high-quality hydraulic oil filtration unit that includes multiple stages of filtration, including coarse filters to remove larger particles and fine filters to capture smaller particles.

Filtration Process: You shut down the press machine and drain the old hydraulic oil. Then, you connect the filtration unit to the hydraulic system and pump the oil through the filters. The filters effectively remove dirt, water, and metal fragments, leaving the oil cleaner and more suitable for optimal system performance.

Refilling: After the filtration process is complete, you refill the hydraulic system with the clean oil. You also take this opportunity to inspect other components of the system for any signs of wear or damage.

Testing: With the clean oil in place, you restart the press machine and observe its improved performance. The sluggishness is gone, and the machine operates more smoothly and efficiently.

Maintenance Schedule: To prevent future contamination issues, you recommend implementing a regular hydraulic oil maintenance schedule. This includes periodic oil sampling and filtration to ensure the hydraulic system continues to operate at its best.
