Here, the sealing surface for signs of wear still need to add the following 103 mechanical seals, 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 mechanical seals Plant, or pumps can form a rough surface highlights. When using two bolts of the gland, the stiffness is not enough 108u mechanical seals, deformation also highlights one of the reasons to form. When this symptom description: A car on the seal may leak HQ901 structure characteristics: HQ901 type mechanical seals belong externally mounted, single-end, multi-spring, static, balanced structure, the spring is not in contact with the medium of mechanical seals, shaft the size of the short. Can replace the seal, container design, simplified installation process, the installation is more simple and convenient. Vice friction materials and auxiliary materials should be selected according to the actual conditions. Scope: Sealed Medium: Oil, water and other liquids. Seal chamber pressure: ≤1.6Mpa sealed chamber temperature: -20 ℃ ~ 160 ℃ line speed: ≤20m / s HQ902 structure characteristics: HQ902 mechanical seal for single face, balanced, multi-spring, static mechanical seal. Spring is not in contact with the media, container design, making installation easier. Vice friction materials and auxiliary materials should be selected according to the actual conditions. Scope: Sealed Medium: Oil, water, sewage, acid and alkali solution. Seal chamber pressure: ≤1.6Mpa sealed chamber temperature: -20 ℃ ~ 160 ℃ line speed: ≤20m / s 104 mechanical seals, mechanical seals, WB2-40 mechanical seal is provided by Anguo Pump Co., Ltd.
