Maintenance Requirements for Deublin 902 120 188 Rotary Union
Regular Inspection: Periodically inspect the rotary union for any signs of wear or damage, particularly focusing on the mechanical seals and bearings. Look for leaks or unusual noises during operation.
Lubrication: Ensure that the bearings are adequately lubricated. The Deublin rotary unions are designed with deep groove radial ball bearings that require minimal maintenance, but it’s essential to check for proper lubrication regularly.
Drainage Management: Ensure that the drain hose is installed with a continuous downward slope to facilitate proper drainage. This prevents fluid accumulation that could lead to seal damage or operational issues.
Cleanliness: Maintain cleanliness around the rotary union. Debris and contaminants can affect performance and lead to premature wear. Clean the union and surrounding areas regularly to prevent buildup.
Monitor Operating Conditions: Keep track of operating pressure and temperature, ensuring they remain within specified limits (maximum pressure of 145 PSI and temperature up to 70°C). Avoid exceeding these limits to prevent damage.
Check Connections: Ensure that all connections (supply and drain hoses) are secure and free from leaks. Loose connections can lead to fluid loss and operational inefficiencies.
Seal Replacement: The balanced mechanical seals made from silicon carbide are designed for long life; however, they may need replacement if significant wear is detected. Follow Deublin’s guidelines for replacing seals when necessary.
Pop-Off Technology: Take advantage of the Pop-Off™ technology that allows unlimited dry running without media pressure during tool changes. Ensure that the seals separate correctly during unpressurized operation to avoid wear.
Professional Servicing: For any major repairs or if you notice persistent issues, contact Deublin or an authorized service provider for professional assistance. Using only Deublin spare parts is recommended for any replacements.
Documentation and Compliance: Keep a maintenance log documenting inspections, repairs, and replacements performed on the rotary union. This helps in tracking performance over time and ensuring compliance with best practices.FAQ of deublin 902 120 188
