The difference between Glyd ring and Step Seal
The main The difference between Glyd ring and Step Seal is:
Glyd ring is a bi-directional sealing ring that can seal pressure in both directions.
Glyd Ring The Gretel ring is composed of a rubber O-ring and a polytetrafluoroethylene ring.
The O-ring bears the force and compensation, while the Gretel ring is used to seal the piston.
It has the characteristics of low friction, approximate creep free, low starting power, and high pressure resistance.
The Glyd ring is divided into holes and shaft grommets, generally composed of rubber O-rings and polytetrafluoroethylene rings.
The O-ring is a force application component that provides sufficient sealing force and compensates for the PTFE ring. The cross section of the Gly ring slider is generally rectangular.
Gly rings are mainly used for piston or piston rod sealing, and the O-ring used for piston rod sealing is inside the slider; The O-ring used for piston sealing is located outside the slider.
The Glyd ring is generally used for bi-directional pressure situations.
The cross-section of the Stefan slider is stepped on one side of the seal (relative motion side). Stern seal is a single acting seal, which is divided into piston Stern seal and piston rod Stern seal.
When using a one-way pressure seal, attention should be paid to the installation direction of the seal during installation; In the case of bi-directional pressure, two back-to-back seal seals should be used.
The sealing effect of the Stuart seal is generally better than that of the Glay ring seal. The slider is composed of polytetrafluoroethylene and copper powder, and its cross-sectional area includes a right angle section, a foot section, a C-section, and so on.
The installation groove of the sealing ring is divided into an open structure and a closed structure.
