Y-shapedY-shaped hydraulic seals are commonly used in hydraulic reciprocating motion of the sealing element

Y-shaped hydraulic seal is one of the commonly used hydraulic reciprocating motion of the sealing element, it not only determines the sealing performance of the hydraulic system, but also affect ancillary mechanical equipment performance and service life. Due to the high cost of reciprocating seal test, a long time, such a large investment in human sealing performance based on ANSYS attention.

 

Such as the use of ANSYS software to simulate different cross-sectional shape of the elastic seal in the hydraulic pressure and stress different compression rates and under different hydraulic distribution, static analysis under a sealed condition Y-shaped hydraulic seal of the forces and dynamic sealing case optimization of the structure and motion parameters.

 

While the static sealing case study the effect of structural parameters of Y-type hydraulic seal on the sealing performance is less. The authors use a large general-purpose finite element analysis software ANSYS Y-shaped hydraulic piston rod with a rubber seal ring under conditions of static sealing conditions were simulated, and the effects of structural parameters and static sealing performance of its operating parameters.

 

As a result of the process of Y-shaped hydraulic piston rod seal is much larger than the deformation and deformation of the cover, so the piston rod and the cap can be regarded as a rigid body, no longer divided solid element mesh. Y-shaped hydraulic seals have three sealed hydraulic reciprocating motion in the system: non-operating state, the state and the static pressure reciprocating state. Non-working state, that is Y-shaped hydraulic seal after installation preload compression naturally occurring state; hydrostatic working condition namely Y-ring constant hydraulic pressure is applied and the Y-shaped hydraulic seal remains stationary operating state; a state that is a reciprocating piston rod work reciprocating motion (within a stroke and an outer stroke constitute a work cycle) working condition. hydraulic seals are commonly used in hydraulic reciprocating motion of the sealing element
