The floating seal ring is a kind of liquid seal. The part is located on the rotating shaft, and the gap ring inside the floating seal ring and the smaller rotating shaft can play a protective role to reduce friction and reduce wear. At the same time, the floating sealing ring is filled with the entire floating ring gap, so the gas medium is prevented from leaking out, thereby functioning as a seal. A spring is also arranged between the floating sealing ring and the fixing ring to press the side of the ring and the fixing ring to prevent the high-pressure sealing oil from leaking from the side, thereby affecting the sealing effect.

The floating seal ring is a non-contact seal with long life and high reliability. Because the material of the floating seal ring seal is made of metal, it is solid and resistant to high temperatures. The floating seal ring seal does not cause wear, the seal is reliable, the maintenance is simple, and the maintenance is convenient.
