Accompanying drawing explanation
Accompanying drawing 1 structural representation of the present utility model.
Accompanying drawing 2 the utility model static components structural representations.
Accompanying drawing 3 the utility model moving ring assembly structural representations.
Embodiment
Mode of execution of the present utility model is now described in detail in detail by reference to the accompanying drawings.
As shown in Figure 1: a kind of dynamic seal apparatus under water, comprises rotating shaft 1, anticorrosion framework oil sealing 2, static components 3, seal casinghousing 4, moving ring assembly 5, insulating medium 6, O-ring seals 7, housing 8.
It is characterized in that: as shown in Figure 1, anticorrosion framework oil sealing 2 is loaded in seal casinghousing 4, and the opening of anticorrosion framework oil sealing 2 originally contacts with extraneous liquid outwardly.Interior and the insulating medium 6 that static components 3 is loaded on seal casinghousing 4 contacts.Moving ring assembly 5 is loaded in rotating shaft 1, and packs in capsul 4, and moving ring assembly 5 contacts with static components 3.Seal casinghousing 4 offers groove, and O-ring seals 7 is loaded in groove.Seal casinghousing 4 is located at the left side of housing 8, forms inner space and is filled with insulating medium 6.
When rotating shaft 1 rotation, anticorrosion framework oil sealing 2 can stop extraneous liquid and all impurity to enter seal casinghousing 4 inside, plays protection static components 3, moving ring assembly 5 and motive sealing function.And moving ring assembly 5 and rotating shaft 1 one starting rotations, static components 3 is positioned at seal casinghousing 4 transfixions.Moving ring assembly 5 fits tightly with static seal assembly 3, stops 6 leakages of built-in electrical insulation medium and extraneous liquid to enter seal casinghousing 4 inside.Play motive sealing function.
The utility model provides a kind of dynamic seal apparatus under water with simple in structure, easy to maintenance, long service life, good seal performance.
