Challenges and Solutions for Deublin 2620 Series Rotary Union

1. Seal Leakage and Premature Wear

Issue: Improper installation, such as incorrect drain line orientation or inadequate coolant filtration, can lead to seal leakage or premature wear.
Solution: Ensure the drain line is installed with a continuous downward slope of at least 15°, ideally positioned at the 6 o’clock orientation in horizontal setups. This facilitates proper drainage and prevents fluid accumulation that can damage seals and bearings. Additionally, maintain coolant cleanliness by filtering to ISO 4406:1999 Code 17/15/12 or better, as contaminants can accelerate seal degradation.

2. Bearing Contamination and Failure

Issue: Coolant ingress due to improper drainage or seal failure can contaminate bearings, leading to increased friction and eventual failure.
Solution: Regularly inspect the rotary union for signs of leakage or contamination. If contamination is detected, replace the affected components promptly. Deublin offers repair services for many of its rotary unions, allowing for the refurbishment and replacement of worn parts.

3. Installation-Induced Stress and Misalignment

Issue: Incorrect installation practices, such as over-tightening or misalignment, can introduce stress on the rotary union, leading to operational issues.
Solution: Follow Deublin’s installation guidelines meticulously. Ensure that mounting surfaces are clean and free from debris, and that the union is aligned correctly without any side loads. Use flexible hoses with adequate length and gentle curves to prevent stress on the union.

4. Incompatibility with Operating Conditions

Issue: Using a rotary union not suited for specific operating conditions, such as pressure, speed, or media type, can result in suboptimal performance or failure.
Solution: Consult with our application engineers to select a rotary union that matches your specific requirements.

By addressing these common issues with proper installation, maintenance, and product selection, the performance and longevity of the Deublin 2620 Series Rotary Union can be significantly enhanced.
