The impact of mechanical seal leakage on operation

Under normal conditions, when the leakage of the mechanical seal is small (close to zero), the formula shows that when the leakage in the mechanical seal is small, the liquid ring in the box is like a solid, and its angular velocity is equal to half of the angular velocity of the turntable.

When the leakage of the seal ring is very large, that is, the circumferential sub-velocity of the velocity vector and the product are constant, and the liquid in the tank moves freely by inertia and is not affected by external force. Under normal working conditions, the pressure radial velocity at any radius indicates that the pressure in the gap of the turntable is distributed according to the parabolic law.

Under the condition of seal ring loss ring, the pressure is also the dotted line in the parabolic distribution, but the two are equal pressure drops.　　317.html,
