1. Hydraulic Seals
Hydraulic seals are rings that are designed to seal areas between the components inside a hydraulic cylinder. A hydraulic cylinder contains many different components, some of which are exposed to high pressure, high temperature and fluids. Hydraulic seals are designed to fit the specific components in a hydraulic cylinder while creating a leak-proof seal around them, to prevent fluid from leaking around these components.
2. Types of Hydraulic Seals
Hydraulic seals are either static or dynamic, depending on their application. Both seal types are used in hydraulic cylinders. The difference is that static seals remain stationary, whereas dynamic seals are exposed to motion.
Static hydraulic seals
They are used in applications where the element with which it's used doesn't move. The static hydraulic seals are not exposed to movement, but they are still exposed to high pressure.
Dynamic hydraulic seals
On the other hand, Dynamic seals are exposed to movement.
Ex. Rod seals are a type of dynamic hydraulic seal. A piston rod is a moving part, and the Rod seals are designed to seal these piston rods.
3. Applications of Hydraulic Seals
Piston seals prevent fluid or other media to by-pass the piston as the system pressure pushes the piston down the cylinder during a pressure cycle. They are generally single-acting seals, which means the stress acts only on one side; and double-acting seals, which means the stress acts on both sides.
Rod seals are deliberated to be the most substantial component of a cylinder sealing configuration. The seals help prevent pressurized hydraulic fluid within the cylinder from leaking. In addition to keeping fluid from leaking, seals also help keep dirt and contaminants out of the cylinder, which extends the lifespan of the cylinder.
