【Q&A Question 025】May 15, 2016: What are the three main components of a mechanical seal? The answer key will be available after responding; scoring is based on answering the key points. 1. The sealing face composed of the moving ring and the stationary ring (also known as the friction pair). 2. The elastic element is a cushioning and compensating mechanism for the main components, and its function is to ensure a tight fit between the sealing surfaces. 3. Auxiliary sealing rings, including rotating ring and stationary ring sealing rings. 4. A transmission mechanism that causes the rotating ring to spin along with the shaft.
The main components of a mechanical seal are: the end-face friction pair (static ring 1 and dynamic ring 2), elastic elements (spring 4), and auxiliary sealing elements.

1. The main components are the moving ring and the stationary ring. 2. Mechanical seal auxiliary seal rings (including O-shaped, X-shaped, U-shaped, wedge-shaped, rectangular flexible graphite, PTFE-coated rubber O-rings, etc.). 3. Springs and thrust rings of the mechanical seal elastic compensation mechanism.
