Background Knowledge：
Bellows mechanical seals and their auxiliary systems currently used mainly have the following forms of seal failures :
Seal failures caused by loss of elasticity or breakage of the bellows.
Seal failure caused by excessive wear of the graphite ring in the mating friction pair.
The sealing failure caused by the surface thermal cracking of the cemented carbide ring in the matched friction pair.
