All mechanical seals have two flat
sealing surfaces
At right angles to the axis of rotation
Parallel to the axis of rotation
Parallel to the end plate
None of these
At right angles to the axis of rotation
Mechanical
seals are used to prevent the leakage of various fluids from compressed vessel
or rotating members. In case of rotating members, both the flat surfacesof the
seals are placed at right angle to the axis of rotation.
Hence,
the correct option is (A).
