QY Static Seal
Function and Usage
QY Static Seal’s sealing effect is played by the interference compression of the two sealing lips. During work, the system pressure is applied at the valley of the QY type seal, which increased the contact stress of the seal lip, cylinder and groove bottom diameter, with the increase of pressure, the contact stress also increases correspondingly, which plays the role of dynamic sealing. Compared with the form of an O Ring combine together with a Back Up Ring, or other compact type static seals, the QY Static Seal are good at resistance to extrusion and easy to install.
 
Advantage
-- Long service life
--Good sealing effect, anti extrusion
--Simple structure, easy to install
 
Material
Material: Polyurethane   Our Material Code: P902
 
Technical Data
Working Pressure: ≤40MPa
Working Temperature:-35℃ to +110℃ 
Working Medium: Mineral hydraulic oil
Tips: Limit value of the above data, can not be used at the same time. The maximum working pressure depends on the type of material, the pressure, the temperature, the gap, and etc.. In actual usage, due to the mutual influence of working parameters, the maximum value setting is lower.
 
Installation
Groove: Closed
In order to avoid the damage of the seals, during the installation, the seals should be leave away with the shape edge of the parts and tools. The sharp edges and burr in the installation area of the seal must be removed.
