Combination of hydraulic seals Seals

Lancaster closure: Manchester seal ring similar to the structure and format, but also by a rubber O-ring with PTFE special quality seal rectangular or trapezoidal shape composed, Lancaster closure with the same cell to circle can divided into the hole and shaft seal Lancaster Lancaster letters, Lancaster closure and sealing of the sealing mechanism and cell to circle the same, but with only one-way Manchester seal sealing effect. Lancaster closure and common features of cell to circle filled PTFE material quality, low friction, no stick-slip, long life.
Grid to circle: grid to circle by rubber O-ring with PTFE seal superimposed square qualitative composition used, the cell to circle can be divided into hole grid to ring and shaft cell to ring, but Their cable sealing mechanism is the same, the deformation of the sealing according to their own high initial surface contact stress, preventing leakage of the liquid without pressure. Working cylinder, the pressure oil to the elastic deformation of the O-ring seal extrusion square, so close to the sealing (metal cable ties)surface, and together with the initial contact stress to prevent the pressure oil from leaking.
Lei ring: bud-rings are made of a synthetic rubbery O-ring of rubber-cloth and a Y-shaped ring composed of the superposition, on its own deformation of the sealing surface of high initial contact stress, prevents stress- leakage of liquid. Working cylinder, the pressure oil to the elastic deformation of the O-ring, has squeezed and stretched Y-ring sealing lip, so close to the sealing surface, and together with the initial contact stress to prevent leakage of pressure oil .
