Take you to understand the basic knowledge of mechanical seals

How much do you know about mechanical seals?

Nowadays, many people don't know much about mechanical seals, which leads to misunderstandings in the process of using them. So what knowledge does mechanical seals have? Mechanical sealing technology relies on a pair or several pairs of end faces that are relatively sliding perpendicular to the shaft. They can still be connected under the action of fluid pressure and other forces of the compensating mechanism, and help the sealing assembly to achieve leakage prevention. role. The mechanical seal makes the contact surface of the static ring and the dynamic ring can still be permanently attached together manually.

The purpose of sealing is achieved by generating an appropriate specific pressure between the static and moving rings and maintaining a liquid film between them. The main components used for machine sealing are end face sealing components such as static rings and moving rings; various types of sealing rings and gaskets such as O-type, U-type and X-type are also used as auxiliary components; compensation components include springs, push rings, etc. ; The transmission components include transmission screws and transmission pins, etc.; the fastening components include many, including push rings, spring seats, glands, and set screws. Under normal circumstances, mechanical seals are mostly used in equipment such as centrifugal pumps, centrifuges, compressors, and reactors. It has good sealing performance, less leakage, longer service life, lower energy consumption, and does not require frequent maintenance. The mechanical seal is also very good in terms of adaptability. Under normal circumstances, it can adapt to various harsh environments such as automated production, high temperature and high pressure, and harsh requirements for sealing.
