The selection of seal type depends on the shaft speed, working pressure and desired sealing effectiveness. Seals for rotary motion include ‘O’ rings, lip seals, face seals, sealing rings,

The seal may also be used to prevent outside materials, such as dirt, from moving in through the clearance. Also Know, how does lip seal work? The primary purpose of a lip seal is to exclude contaminants while retaining lubricants. By nature, lip seals function by maintaining friction. They can be used in a variety of applications from slow

Abstract. The welded lip seals form part of the torus primary vacuum boundary in between the port plugs and the vacuum vessel, and are classified as Protection Important Component. In order to refurbish the port plugs or the in-vessel components, port plugs have to be removed from the machine.

Rotating shafts can be affixed with a shaft seal. The shaft seal is placed around the rotating shaft, at which point it seals the oil- or 

There is a positive seal at the tip of the sealing element. The lubricity that is required to prevent excessive frictional heat is provided by a smooth hard- 

The majority of elastomer rubber lip seals use an extension spring for the loading mechanism for tight sealing. Typically, the spring is found directly above the seal to shaft interface contact point, giving the necessary loads to pinch off the oil film. OmniSeal ® PTFE lip seals do not use extension springs for sealing in the majority of cases.

The chemically resistant P.T.F.E. component is spring loaded, to force the flexible angular lip of the wedge, into tight contact with the shaft. The same spring force impacts a sufficient load to the rotary face to create a suitable seal interface, with a varied choice of standard stationary seats. Examples of PTFE Wedge Mechanical Seals

Propeller shaft seals work by allowing the prop shaft to both exit the boat and rotate while at the same time keeping the water on the outside. The shaft seal also lubricates the shaft (not unlike a stuffing box) as it exits the boat. Most propeller shaft seals consist of a housing with O ring lip seals and or face seals.

How Shaft Seals Work. Shaft seals work like most other seals by compressing the surface, or in this case the shaft, on which they are installed. Most of them feature an outer case consisting of steel or an elastomer material, followed by a lip consisting of an elastomeric or thermoplastic material. Rotating shafts can be affixed with a shaft seal.
