Mechanical seal -- Selection of springs and bellows
Thread Content
Hello, sea friends. I would like to ask for advice on choosing springs and bellows for mechanical seals, especially in environments where the material may reach high temperatures and undergo polymerization. I hope experts can share their insights: P
Metal bellows mechanical seals have one fewer leakage point, making them suitable for applications involving high temperatures and highly viscous materials.
For high temperatures, bellows are more suitable. Regarding polymerization, neither of these sealing types can effectively prevent leaks caused by sticking that occurs after polymerization; however, the risk associated with springs is relatively lower. But it also contradicts high-temperature media. You can consider using a bellows with external flushing, or a bellows with self-flushing and cooling to solve this issue.
For high-temperature media, it’s better to use bellows
