What is a Mechanical Seal?
A mechanical seal is a precision-engineered device that prevents leakage between two surfaces in relative motion. Essentially, it forms a barrier to contain fluids within a system while allowing for the movement of a rotating shaft. How it Works: Two Primary Faces: At the heart of a mechanical seal lie two precisely machined faces: one stationary and the other rotating with the shaft. Contact and Friction: These faces maintain a controlled contact under pressure, creating a barrier against fluid leakage. Friction Management: To minimize friction and wear, a thin film of fluid or lubricant often exists between the faces. Materials Matter: The choice of materials for these faces is crucial. Common options include carbon graphite, ceramics, and tungsten carbide, each with specific properties for different applications. Why are Mechanical Seals Important? Prevent Leakage: The primary function is to prevent leakage of fluids, such as chemicals, gases, and even water, from t...
