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 media, a shorter axial dimension. Can replace the seal, cartridge mechanical seal design simplifies installation process ISW100-160IA machinery dense, more simple and convenient to install. 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: Front ≤20m / s pump start must be checked:. A sealing system for all fittings connected ISW100-160I whether mechanical seals, whether the system is working state. Inhalation valve should be open, until the liquid (medium) and then open the motor into the sealed chamber. b. the pump and seal chamber is filled with liquid. c. the sealed chamber Have exhausted air. Especially with the double-end sealing liquid seal ISW100-160 mechanical seal, it should be noted drained air. d. Turning examination should feel resistance, but should not have a heavy or wiring. 13, when the double mechanical seal work, isolation fluid pressure than the seal chamber pressure medium high 0.05-0.2MPa. 14, the relevant parameters: mechanical seal installation shaft (or sleeve) to be chamfered at the step 3 × 10 °, and the smooth transition, its roughness Ra≤1.6. Axis (or sleeve) surface roughness Ra≤1.6, runout ≤0.04mm, dimensional tolerances h6. Installation of mechanical seals and sealing cover secondary seal contact area of ??the surface roughness of the stationary ring Ra≤1.6, dimensional tolerances for H8, locating the vertical face of the shaft ≤0.04mm. ISW100-125A mechanical seals, mechanical seals Ali, pipeline pumps supplied by Anguo Shi Yuan Pumps Limited. Anguo Shi Yuan Pump Co., Ltd.
