Differences between wet mechanical seals and dry mechanical seals
Thread Content
When reading information on mechanical seals, one often comes across terms such as wet mechanical seals and dry mechanical seals; what are the differences in their sealing capabilities?
Wet type, with a liquid film between the sealing surfaces； Dry gas; there is an air film between the sealing surfaces.
Agree with what was said above: Wet mechanical seal: a liquid film exists between the friction surfaces; Dry mechanical seal: a gas film exists between the friction surfaces
I agree with the moderator on the first floor; moreover, the flushing methods for wet and dry mechanical seals are also different
This expression is not common; either the liquid pump uses a wet type while the air pump uses a dry type, meaning that the liquid is in a wet state and the gas is in a dry state
A dry mechanical seal refers to a mechanical seal that does not require flushing water. This mechanical seal is designed with a heat dissipation device, which helps to quickly reduce the frictional heat generated during operation, thereby achieving water conservation.
**Are there standard definitions in the specifications? Which expert knows?
Wet seal: the isolation fluid is in liquid form; dry seal: the isolation fluid is nitrogen
