, Seal failure mainly has the following three reasons: (1) sealing surface in the repair of mechanical seals when open, 85 percent of seal failure was not caused by abrasion, but had been leaked before the wear. When the sealing surface opened, medium solid particles into the sealing surface under the action of the liquid pressure after sealing surface close 65ZJ-I-A30 mechanical seals, these solid particles can be embedded soft ring (usually the right ink Central) face It actually became a "Wheel" will damage the hard ring surface. Since the ring or rubber ring is fastened to the shaft (sleeve) on the mechanical seal, when the shaft string action, the ring can not be fit in time, leaving open the sealing surface and the sealing surface of the closure lag, on the solid particles into the seal plane. There is also between the shaft (sleeve) and the sliding member having the solid particles affect rubber ring or a sliding ring (as opposed to dynamic seal point, common fault). Also 80ZJ-I-A33 mechanical seal, media will produce a rubber ring and the shaft (sleeve) crystals friction parts, there will be in the spring at the solid matter, will open the sealing surface. Sealing ring is the ring and stationary ring collectively (below), are the most important elements of mechanical seals. Sealing ring largely determines the mechanical seal performance and life, therefore, it made a number of demands. 1. Have sufficient strength and rigidity. Under operating conditions (such as pressure, temperature and sliding speed etc.) are not damaged, deformed to be as small as possible while still maintaining the sealing operating conditions fluctuate. 2. Seals should have sufficient hardness and corrosion resistance, in order to ensure a satisfactory service life under operating conditions. 3. Seal ring should have good thermal shock resistance. To this end, it requires materials with high thermal conductivity and a small linear expansion coefficient 80ZJ-I-A36 mechanical seals, and will not crack when subjected to thermal shock. 4. Seal ring should match the smaller friction coefficient and good self-lubricating, sealing ring material and sealing fluid also has good wettability. Work in the event of a short period of dry friction, does not damage the seal faces. 5. Seal ring should be simple, symmetrical and priorities with the overall structure. May also be combined (such as cassette type) sealing ring, try to avoid using the seal face coating structure. 6. Sealing ring easier to manufacture, installation and maintenance to be convenient, the price is low.
