Description

technical field

[0001] The invention relates to a yacht, in particular to a mechanical sealing device used on the propeller shaft of the yacht. Background technique

[0002] The mechanical seal device on the yacht propeller shaft is used to isolate the water from the electrical equipment on the yacht, and requires high sealing performance and reliability.

[0003] From the current point of view, the structure of the mechanical seal device on the yacht propeller shaft is shown in Fig. image 3 , there are the following problems: 1) The centering shaft sleeve and the rubber bellows are prone to rotation and slippage when they cooperate with the transmission, resulting in seal leakage; 2) The static seal ring has no protection device, is easy to wear, and has low mechanical shock resistance. Short service life. Contents of the invention

[0004] Aiming at the deficiencies in the prior art, the invention provides a sealing device with novel structure, good sealing performance...
