The function of the seal is to prevent leakage. The parts that play a sealing role are called seals. The place where the seal is placed is called the sealed box or sealed slug. More complicated seals, especially those with auxiliary systems, are called sealing devices. The seal of the static part is called the static seal; the seal of the relative moving part is called the dynamic seal. The commonly used dynamic seal is the seal of the rotating shaft and the reciprocating rod, referred to as the shaft seal and the rod seal. In addition, there are seals for spiral moving parts and swinging parts.　　187.html,
