What is crucial for the proper performance of a mechanical seal?

The proper performance of a mechanical seal relies heavily on an accurate surface finish. The surfaces that come into contact within the seal must be smooth and precisely machined to ensure a tight seal that prevents leakage. If the surface finish is rough or improperly aligned, it can lead to increased friction, wear, and ultimately seal failure.

A highly polished and precisely finished surface allows for better contact, reducing the likelihood of gaps that could allow fluids to escape. This attention to detail in the surface finish is vital in manufacturing seals, as it directly affects their reliability and lifespan. Without it, even minor imperfections can lead to significant problems in a mechanical sealing application.

While factors like correct lubrication, consistent temperature, and regular cleaning are also important in maintaining the function of a mechanical seal, they do not directly impact the fundamental interaction between the sealing surfaces as significantly as surface finish does.
