An overview,

KDAS composite seal is A double-acting piston seal, consisting of three parts: an elastomer A, two supporting rings B, and two guiding rings C.

Elastomer A has A special section with three sealing lip against the cylinder wall (dynamic seal). The middle lip is thicker and ACTS as the main seal, while the other two lips act as the auxiliary seal. The bottom side is close to the bottom of the piston groove (static seal), and the contact surface is relatively large.

The supporting ring B is placed on both sides of A for positioning purpose. To support elastomer A and prevent radial seal clearance of A. The supporting ring B is in a stepped shape, and there are many convex blocks on the side in contact with the sealing element to prevent the sealing ring from rotating during operation.

The guide ring C is rectangular and is mounted on the piston to guide and absorb axial forces. The guide ring is provided with several axial grooves up and down to allow pressure oil to flow through the guide ring, so that elastomer A can feel all the working pressure and release pressure quickly when changing direction. This is A good way to prevent the elastomer A before the generation of continuous ultra-high pressure.

KDAS composite sealing material hardness from the inside to the outside gradually increase, according to its characteristics, play a sealing, supporting and guiding role. KDAS combination seal for self - tightening double - acting seals. In the initial state, the deformation of elastomer A produces A radial pre-tightening force, which increases with the increase of system pressure, thus producing A complete sealing force. Even if the system has no pressure, the sealing effect can be achieved.


Performance and use

KDAS combination seal is an integral seal with only one groove for sealing and guiding elements. Fit into enclosed grooves, one for each piston. The compact sealing structure makes the total length of piston (cylinder) shorter, reduces the processing cost and has excellent anti-clearance backlog performance. Elastomers do not twist when working and have a reasonable leakage to reduce friction. Mainly used for piston and hydraulic cylinder seal. Such as bulldozers, excavators, loaders, cranes, hydraulic gates and agricultural machinery.
