Basic knowledge of mechanical seals
- Aug 28, 2018 -

Mechanical seals are one of the basic mechanical components with precise and complicated structure. They are the key components of various pumps, reaction synthesis kettles, turbine compressors, submersible motors and other equipment.


1. The basic concept of mechanical seal:

Mechanical seal refers to a device for preventing fluid leakage caused by at least one pair of end faces perpendicular to the rotation axis under the action of fluid pressure and compensating mechanism elastic force (or magnetic force) and the cooperation of the auxiliary seals. The auxiliary seal of the compensation ring is a metal bellows called a bellows mechanical seal.


2, the composition of the mechanical seal:

There are mainly four types of components. a. Main seals: moving ring and static ring. b. Auxiliary seal: seal ring. c. Pressing parts: spring, push ring. d. Transmission parts: magazine holder and key or fixing screw
