How to use the glace ring and stadt seal?
The Glea ring is composed of a rubber ring and a polytetrafluoroethylene ring, and is made of polytetrafluoroethylene nitrile rubber. In special cases, the rubber elastomer nitrile rubber NBR uses fluorine rubber FKM, which can be divided into hole grid and shaft grid, but its sealing effect is the same. According to its own deformation, a higher initial contact stress is generated on the sealing surface, thereby preventing the leakage of pressureless liquid. When the hydraulic cylinder is working, the pressure liquid kneads the square sealing ring through the elastic deformation limit of the O-shaped sealing ring to make It fits closely with the sealing surface to generate a higher additional contact stress, which increases with the increase of pressure, and the initial contact stress is common

The Glaus CircleIt is composed of a rubber ring and a polytetrafluoroethylene ring, and is made of polytetrafluoroethylene nitrile rubber. In special cases, the rubber elastomer nitrile rubber NBR uses fluorine rubber FKM, which can be divided into hole grid and shaft grid, but its sealing effect is the same. According to its own deformation, a higher initial contact stress is generated on the sealing surface, thus preventing the leakage of pressureless liquid. When the hydraulic cylinder is working, the pressure liquid kneads the square sealing ring through the elastic deformation limit of the O-ring to make it closely fit with the sealing surface, resulting in a higher additional contact stress, which increases with the increase of pressure. The initial contact stress jointly prevents the leakage of pressure liquid.
The Glaus ring is a cylinder seal, device and device. The O-ring is installed first, and then the Glaus ring wear ring is installed. For small standards, the method of direct installation is generally adopted, heated with oil, the oil temperature should not be too high, the wear ring can be softened and then sleeved on the shaft, which can be cooled. For large standard Grammy ring majors, use a tapered sleeve, From the small end of the sleeve to the big end, and then push it into the groove.
StefonThe device and device of the seal are also the wear ring of the seal after installing the O-ring first. When installing the wear ring, first press the wear ring slightly along the diameter direction, then install the wear ring in the groove, and then smooth the compression deformation by hand. When installing in the northern winter, the wear ring must be heated first, and then sleeved on the shaft. After cooling, install according to the above method. When placing the shaft, be sure to observe whether the shaft is completely inserted into the wear ring, and pay attention to the guide belt not to jam and hold the shaft, otherwise the guide belt may be squeezed out and the seal groove may be crushed.
