Discover the top causes of air leakage in rotary airlock valves and practical maintenance steps to ensure 99% sealing efficiency in your pneumatic conveying system.
Understanding Air Leakage in Rotary Valves
Air leakage in rotary valves (or rotary airlocks) significantly reduces the efficiency of pneumatic conveying systems. It can lead to material degradation, reduced conveying capacity, and increased energy consumption.
Common Causes of Leakage
- Rotor Tip Clearance: As the rotor turns, the gap between the rotor tips and the housing naturally increases due to wear.
- Seal Failure: Worn shaft seals allow air to escape.
- Improper Venting: Lack of proper venting causes blowback.
The Oswar RALX Solution
Our RALX series features adjustable rotor tips and a precision-machined housing that maintains tight clearances for longer periods. With our Graphite Sealing System, we achieve up to 99% sealing efficiency, minimizing air loss.
Maintenance Tips
- Regularly inspect rotor tip clearance.
- Check shaft seals for wear every month.
- Monitor pressure differentials across the valve.
