A wide variety of seals are used in all kinds of machinery.

Seals have the following functions:

Prevent the seal lubricant from leaking from the inside
Prevent the outside dust, foreign matter (dirt, water, metal powder, etc.) from entering
Oil seals come in various shapes to suit the machine and the material that needs to be sealed. The main function of a mechanical seal is to prevent the leakage of gases and liquids in rotating shaft applications. It is widely used in rotating shaft sealing of pumps, kettles, compressors and other similar equipment.

How does a mechanical seal work?

Mechanical seals usually consist of a moving ring, a stationary ring, a compression element and a sealing element. These parts fit tightly together to form a sealing surface to avoid leakage. The liquid in the sealing chamber makes the end face of the moving ring close to the end face of the stationary ring. The mechanical seal acts on the end faces of the two rings. This fit is to maintain the compression pressure of the element.

What are mechanical seals made of?

Mechanical seals are designed in a variety of ways and can be made of a variety of materials. In fact, the material of the sealing surface determines the service life of the mechanical seal. The most commonly used materials include rubber, stainless steel, PTFE, carbon, ceramic, silicon carbide and silicon carbide.
The role of mechanical seals:
Seal: Prevents leakage of equipment fluids.
Contain: Confines process fluids and prevents them from escaping into the environment.
Lubricate: Minimizes friction and wear between seal faces.
Compensate: Accommodates shaft misalignment and axial movement.
Thermoregulate: Manages heat generated by friction within the seal.
