QGB cylinder seals to technical requirements

QGB cylinder seals to the technical requirements of QGB cylinder pressure above the MPa, the height of the seal to the size of the seal root of deformation, which is the size of the extrusion clearance, because a washer has hardness, deformation, plus washer is to reduce the deformation of seal. Seals at high pressure, the roots reduced and the possibility of the piston rod or cylinder wall friction, thereby reducing the seals the roots out of the strain and the risk of damage. Washer is the relationship between hardness and pressure, the greater the pressure, the greater the hardness. Because the root of the dual seal width less than the special seal the width. At high pressure and seal the roots of the deformation is large, special seal under the same pressure in the roots with wider, compression deformation is small, is the possibility of the piston rod extrusion is smaller. QGB cylinder to choose special seals, such as the shaft seal, can only choose shaft seals. Piston seal can only choose piston seals, not choose axis and the piston and seals.
