Scope: seal chamber pressure: P≤0.8MPa sealed chamber temperature: t = -20 ℃ ~ 80 (150) ℃ line speed: Vg≤10m / s BIA mechanical seal material combinations Schedule as follows: mechanical seal material code table BIA Mechanical seal bore size as follows (Unit: mm) Model ID Model ID Model ID BIA-14 14 BIA-32 32 BIA-48 48 BIA-16 16 BIA-33 33 BIA-50 50 BIA-18 18 BIA-35 35 BIA -53 53 BIA-20 20 BIA-38 38 BIA-55 55 BIA-25 25 BIA-40 40 BIA-58 58 BIA-28 28 BIA-43 43 BIA-60 60 BIA-30 30 BIA-45 45 Part Names Y I reinforced PTFE metal surfacing neoprene T N E chrome steel H other materials hydrogenated nitrile rubber, seal failure following three main reasons: (1) open at the time of the sealing surface repair of mechanical seals, 85 % of seal failure is not due to wear and tear caused, but had been leaked before wear. When the sealing surface of a mechanical seal open ISG125-100, medium solid particles from entering the sealing surface under the action of the liquid pressure, the sealing surface is closed, these solid particles can be embedded soft ring (usually right ink ring) surface, which actually became a "Wheel" will damage the hard ring surface. Since the rubber ring or rings fastened to the shaft (sleeve), when the movable shaft string when ISG100-250IB mechanical adhesion, ring can not be bonded, leaving the sealing surface to open and close the sealing surface of the hysteresis, causes the solid particles into the sealing surface. There are also between the shaft (sleeve) and the sliding parts with solid particles, affecting rubber ring slide or snap ring (relative dynamic seal point ISG100-350 mechanical seal, a common fault). In addition, the media also have a rubber ring and the shaft (sleeve) crystals friction parts, there will be in the spring at the solid material, will open the sealing surface.
