[Three rain valve to recommend the star product - Mechanical seal] mechanical seal (mechanical seal) is defined by at least one axis of rotation perpendicular to the face of the compensation mechanism under fluid pressure and elasticity (or magnetic) role and secondary seal fluid leakage with holding means affixed under the combined constituted prevent relative sliding. Elastic loading mechanism and secondary seal is metallic bellows mechanical seal we called metal bellows seal. In light seal H76-40 mechanical seals, as well as the use of rubber bellows mechanical seal secondary seal H76-55, H76-45 limited elastic rubber bellows mechanical seal, generally need to be supplemented to meet the load spring stretch. "Mechanical seal" that is often referred to as "mechanical seal." [Three rain valve to recommend the star product - Mechanical seal] Description: For the sealing surface wear marks still need to add the following mechanical seal, check the wear marks that can help analyze failures. (1), and wear wider: Indicates the pump was a serious misalignment. The reason is: a, bearing damage; b, shaft vibration or axial deformation; c, shaft bending; d, pump cavitation vibration; e, uncoupled pair; f, severely deformed tube; g, seal stationary ring tilt. (2), wear scar narrowing: grinding marks narrower than the minimum width of the two sealing surfaces, which illustrate the sealing overpressure, pressure or temperature of the sealing surface deformation. (3), no wear marks: Description sealing surface is not bonded. Check the springs and other compensation mechanism is slipping or impeded. (4), the sealing surface no wear marks, but there are bright spots. Sealing surface will be a bright spot without warping wear scar. Pressure is too high, the gland bolts screwed good or not good clip, or pumps can form a rough surface highlights. When using two bolts of the gland, the stiffness is not enough, the deformation is another cause of highlights. When this symptom description: a drive to seal the leak may occur.
