Figure 1 Use type of bellows
Bellows are commonly divided into two sorts: shaped bellows and welded bellows. The product of bellows made use of in extremely-substantial vacuum program is frequently SUS316 stainless metal.
To make a molded bellow with a somewhat bigger diameter, initial roll the stainless steel plate into a tube shape and weld it at the joint. Insert the cylinder into the bellows mould and complete the production of the formed bellows by hydraulic stress.
In the ultra-high vacuum process, Nuclear Glove Box the bellows connecting the molecular pump and the mechanical pump are primarily fashioned bellows with NW flanges at both ends.
The advantages of formed bellows are easy output and small expense. The disadvantage is inadequate extend and flexibility. Welding bellows make up for the lack of molded bellows.
Welded bellows is a slim-walled pleated hose produced by welding an annular stainless steel sheet with an inner diameter and an outer diameter alternately (Figure 2). The welding system is plasma welding. This bellows has wonderful adaptability and is an indispensable component in the connection of ultra-substantial vacuum devices and various motion introducers. Fairly find the pure duration of the bellows, and the support existence can get to more than hundreds of 1000's of occasions.
