[Three rain valve to recommend the star product - Mechanical seal] Description: confirm the seal (1) to confirm whether the requirements of sealing the same model installed. (2) carefully before installation and assembly diagrams contrast, the number of parts are complete. (3) the adoption and transmission coil spring mechanical seals M74-35 mechanical seal, whose spring has left and right hand points, shall always choose the shaft rotation. Friction: At the top of the compensation and non-compensation ring ring inlaid with a pair of seal face mechanical seal, play a major role in sealing machine seal. Under normal circumstances compensate narrow ring of soft material, end; uncompensated manufacturing ring with a hard material, end wider. [Three rain valve to recommend the star product - Mechanical seal] Description: seal failure main reasons: the sealing surface of the mechanical seal is opened when repairing M74-25 mechanical seal, 85 percent of seal failure is not caused due to wear and tear, but wear had leaked before. When the sealing surface is opened, the medium of solid particles into the sealed 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) M74-40 mechanical seal face, which actually became a "Wheel" will damage the hard ring surface. When the speed <20-30m / s, the choice of spring rotary structure; when higher speed, unbalanced mass of rotating parts can lead to strong vibration, the choice of spring static structure.
