The main advantages of using sealing rings for filling machines are:
1. Good sealing effect - Reliably prevent liquid and gas leaks.
2. Easy to use - Simple and quick installation and removal.
3. Low sealing pressure - Reduces mechanical wear and energy consumption.
4. Wide sealing range - Can be used for static and dynamic sealing.
5. Long seal life - Well-made seals can be reused.
6. Low cost - Lower use and maintenance costs compared to mechanical seals.
7. Self-healing - Seals can self-repair seals when surfaces are damaged.
8. Corrosion resistance - Corrosion resistant materials can be chosen.
9. High temperature resistance - Special materials can withstand up to 300°C.
10. Shock absorption - Absorbs impacts and vibrations to protect sealing surfaces.
In summary, using seals can simplify design, improve sealing performance of filling machines, and prolong service life.
