How To Correct Mechanical Seal Wear?
Apr 28, 2018

How to correct mechanical seal wear?

How to fix the mechanical seal if worn out? Spindle mechanical seal bushing correction, the traditional two commonly used methods.

  Method one: Plane the spindle seal bushing with a gouging, replace the new bushing and weld it. In this method, mechanical seals for kettles require a large amount of labor and welding is difficult, and each replacement must be drilled on the main shaft, which is not conducive to the safety of the main shaft of the set.

  Measure two: Shave and lubricate the wear part of the spindle seal bushing. Use a mechanical seal of the same material as the kettle to control the temperature and current. Use manual argon arc welding to repair the weld. The weld is 1mm higher than the base surface of the base metal. After grinding, polish and polish, check with flaws to avoid cracks until you reach the design request. This method has long welding time, messy skills, time-consuming work, and the spindle and liner deformation is not easy to control, and the safety hazards are large. It simply constitutes a ring-shaped short circuit shaft current and burns the bearing.

Measure three: Sole liquid ceramic amendments

  The liquid ceramic polymerization data is the combination of special fibers, ceramics, silicon steel and other materials by means of polymerization skills, so that it not only has superior strength and hardness, but also has excellent corrosion resistance, making it the worst dry grinding The environment can also show a fantastical effect.

  The construction process is as follows:

  1. The surface of the substrate is roughened.

  2. Cleaning. Clean the equipment with absolute ethanol and clean cotton yarn.

  3 Harmony data. The seasoning must be well-mixed to ensure that the adjusted material is uniform in color and free of variegated color.

  4. Coating data.

  5. Curing.
