SNAK Factory ISO Certificated UN UNS UHS IDU U+S UPH VES IDI ISI SPG SPGW SPGO KDAS Hydraulic Cylinder Piston Rod Seal Series
Hydraulic cylinder seals are used to seal the opening between various components in the hydraulic cylinder. There are two main types of hydraulic seals in the system:
* Dynamic seals
They seal between components in relative motion. In a hydraulic cylinder the rod sealing system seals dynamic reciprocating motion
between the piston rod and head, while the piston sealing system seals dynamic reciprocating motion between the piston and
cylinder bore.
* Static seals
They seal between components fixed together without relative motion. Hydraulic cylinders use static seals in various locations
depending on the design and construction. The most common are static seals between the piston and piston rod and between the head
and cylinder bore tube.
*01.Piston seal functions
* Act as pressure barrier and prevent fluid passing the piston – important for controlling the cylinder motion or maintaining the position when at rest
*02.Rod seal functions
* Act as pressure barrier and keep the operating fluid inside the cylinder
* Regulate the fluid film which extends with the surface of the piston rod – important to inhibit rod corrosion and to lubricate the wiper seal and the rod seal itself
* Accept the lubrication film back into the cylinder when the rod retracts
*03.Wiper seal functions
* Exclude external contaminants from entering the cylinder assembly and the hydraulic system
* Accept the lubrication film back into the cylinder when the rod retracts
*04.Guide rings (rod and piston) functions
* Prevent metal-to-metal contact between components
* React the radial load caused by side loads on the cylinder assembly
* Keep the piston rod and piston accurately centred in the cylinder assembly – important for performance of the rod sealing system and piston sealing system
