Pressure flow and non-pressure flow of mechanical seal

Mechanical seals can be divided into pressure flow or pipe flow and non-pressure difference flow or channel flow according to the different perimeters that the fluid movement contacts. In fluid mechanical seals, there is mostly pressure flow, such as the aforementioned differential pressure flow (Bosuye flow).

The characteristic of pressurized flow is that the entire perimeter of each flow-through chamber of the fluid is in contact with the surface of the body. The return force of each section is usually greater than or less than the atmospheric pressure, and the pressure along the way changes. The fluid depends on the pressure at both ends.
