Failure mode and use the rubber ring is related to hypertension is usually so pressing ○-ring failure of one of the reasons, when found ○ type hardens into a rectangle or ring when ISG125-315A mechanical seal, you need to adjust the amount of compression, otherwise it will fever. It is necessary to understand the use of a synthetic rubber temperature. Synthetic rubber ring big swell mostly due to chemical erosion caused ISG125-250B mechanical seals, they all have some of their own characteristics, such as fluorine rubber resistant to high temperatures, and ethylene, propylene ○-rings used in the petroleum oil will swell ISG125-315 mechanical seals, NBR aggressive ozone effect, so do not install nitrile rubber in the motor, so the high temperature and chemical corrosion is usually caused by hardening of rubber products, the main reason for the crack. When installing rubber parts were cut and surface nicks mechanical seals, seal failure is a common cause. The signs of the old fixed screw shaft, keyway, spline shaft, sharp shoulder so will damage rubber parts. 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, 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 Shihezi mechanical seals, ISG125-250 mechanical seals, pipeline pumps (by Shi Yuan Anguo Anguo City Pump Co., Ltd. to provide stone.
