No, new hydraulic oil is not considered clean and should be filtered before use.
Why New Hydraulic Oil Isn't Clean
It’s a common misconception that brand new hydraulic oil is immediately ready for use. The reality is that even fresh out of the container, hydraulic oil can contain contaminants that can damage hydraulic systems. As highlighted in our reference material:
“New oil is not clean oil and must be filtered before use.”
This statement underscores the importance of pre-filtering even new hydraulic fluid to ensure optimal system performance and longevity.
Sources of Contamination in New Oil
New hydraulic oil can be contaminated from various sources during manufacturing, storage, and transportation. These include:
- Manufacturing Processes: Residues and particles may be introduced during the oil production process.
- Packaging and Handling: Contaminants can enter during the filling and sealing of containers, or during handling at warehouses and stores.
- Transportation: Dust and other airborne particles can infiltrate through vents or seals during transport.
The Need for Filtration
Regardless of the source, these contaminants—including tiny abrasive particles like sand and dust—can cause significant problems in hydraulic systems, leading to:
- Reduced Efficiency: Contaminants can clog valves and other components, hindering performance and increasing energy consumption.
- Increased Wear and Tear: Abrasive particles accelerate wear on critical parts like pumps, cylinders, and seals.
- System Failure: Over time, the buildup of contamination can lead to costly repairs and downtime.
Practical Steps to Ensure Clean Oil
To ensure the hydraulic oil is suitable for use, you should take the following measures:
- Always Filter New Oil: Implement a rigorous filtration process before adding new oil to the system.
- Use Appropriate Filtration Systems: Employ centrifuge filtration systems or other suitable methods to remove contaminants effectively. These systems are particularly good at removing tiny abrasive particles.
- Regularly Monitor Oil Condition: Conduct periodic oil analysis to assess the level of contamination and identify the need for further filtration.
- Follow Best Practices: Adhere to established guidelines and procedures for handling, storing, and adding hydraulic oil.
Conclusion
Even though hydraulic oil is considered new, it's crucial to recognize that it is not inherently clean. The presence of contaminants necessitates filtration before use to prevent damage and ensure optimal performance.
