Mechanical seal rings or faces play a crucial role in mechanical equipment. Mechanical seal is a device used to prevent fluid leakage, typically installed on a rotating shaft to isolate the working medium from the environment. The main components of mechanical seals include dynamic rings, static rings, spring seats, anti rotation pins, push rings, O-rings, etc. Among them, the dynamic and static rings are the core components of mechanical seals, and their sealing surfaces form a seal when they move relative to each other, mainly using SiC material.
SiC mechanical seals have the characteristics of wear resistance, high hardness, long service life, good corrosion resistance, high temperature stability, and long service life. By utilizing the characteristics of SiC mechanical seals, they are widely used in fields such as petrochemicals, pharmaceuticals, food, aerospace, etc. Therefore, with the continuous development of industrial technology, the market demand for SiC mechanical seals will continue to grow.
When choosing a mechanical seal ring or face , the following key factors need to be considered:
Firstly, in terms of application environment, mechanical seals are mainly used for rotating applications. In extremely harsh environments, they can withstand severe wear and prevent the intrusion of harsh and abrasive external media.
Secondly, there are two types of seals: mechanical face seals and heavy-duty seals. Type D is the most common form, which uses an O-ring as the secondary sealing element; Type DF has an elastic body with a diamond shaped cross-section as the secondary sealing element.
Thirdly, material selection is crucial for the performance of mechanical seals. Suitable sealing surface materials need to be selected based on factors such as working medium, temperature, and pressure.
