1. It is not sensitive to the operating status of the machine and has stable sealing performance;

2. The floating sealing ring does not cause wear, the sealing is reliable, the maintenance is simple, and the inspection is convenient;

3. The floating seal ring has simple specifications and structure, with only a few simple-shaped rings, pins, springs and other parts;

4. The floating sealing ring is made of metal and is resistant to high temperatures;

5. Because there is a liquid film in the sealing gap, the friction power is extremely small, making the machine more efficient;

6. It can form a multi-layer floating ring, which can effectively seal high pressure above 10MPa;

7. The high-speed fluid mechanical process can be between 10000 and 20000r/min, and the speed can be as high as 100m/s or more;

8. Use corrosion-resistant metal materials or graphite materials as sealing rings, which can be used for sealing strongly corrosive media.
