Which component in a mechanical seal typically acts on the seal face?

In a mechanical seal, the component that typically acts on the seal face is the coil springs. The primary function of the coil springs is to exert a compressive force on the seal faces, ensuring they maintain contact with one another. This contact is essential because it allows the mechanical seal to effectively prevent leakage of fluids across the interface of the rotating shaft and the stationary housing.

Coil springs provide the necessary tension to keep the seal faces pressed together as the equipment operates, accommodating for any movement or vibration that occurs during operation. As the equipment starts, the springs help ensure that the sealing faces align correctly, which is critical for maintaining a proper seal and ensuring that no fluid escapes.

The interaction between the seal face and the force from the coil springs is crucial in achieving a leak-proof condition, thus allowing the mechanical seal to function properly and perform its intended task effectively.
