A fundamental concept is the or load factor (K) . This dimensionless number determines how much of the hydraulic pressure is used to close the seal faces. By carefully designing the geometry of the seal faces and the secondary seal diameter, engineers can "balance" the seal. A properly balanced seal (with a K value typically between 0.6 and 0.9 for liquids) maintains a stable fluid film without excessive face loading, reducing friction and heat generation. This principle is widely recognized as one of paramount importance.
The choice of materials for the seal faces is crucial. Common material pairings include: By carefully designing the geometry of the seal
Seals can be designed as "balanced" or "unbalanced." Balanced seals reduce the hydraulic closing forces on the faces, allowing them to operate at much higher pressures without squeezing out the lubricating fluid film.
Utilize dynamic secondary seals (like O-rings) that move axially along the shaft to compensate for face wear or shaft misalignment.
