How to correct mechanical seal wear1

How to correct mechanical seal wear There are two traditional methods for correcting the spindle mechanical seal bushing. Method 1: Gouging open the main shaft sealing bushing, replace the bushing with a new one and weld it. This method requires a lot of labor for the mechanical seals used in the kettle, and the welding is difficult, and the main shaft must be drilled every time it is replaced, which is not conducive to the safety of the main shaft of the unit. Method 2: Grind and lubricate the worn parts of the spindle seal bushing, use the welding wire of the same raw material as the mechanical seal, control the temperature and current, and perform repair welding with manual argon arc welding. The welding seam is about 1mm higher than the base surface of the base metal. After finishing, grinding and polishing are carried out, and inspection is carried out with flaw detection to avoid cracks until the design requirements are reached. This method takes a long time for welding, complicated skills, time-consuming and labor-intensive, and the deformation of the main shaft and bushing is not easy to control, and the safety hazard is large. Method 3: Soler liquid ceramic correction method Liquid ceramic polymer materials are bonded and combined with special fibers, ceramics, silicon steel and other materials through polymerization technology, so that they not only have ultra-high strength and hardness, but also have excellent corrosion resistance. , so that it can perform beyond fantasy in the harshest dry grinding environment. The construction process is as follows: 1. The surface of the substrate is roughened. 2. Cleaning. Clean the equipment with anhydrous ethanol and clean cotton yarn. 3. Harmony data. When seasoning, be sure to mix thoroughly and evenly to ensure that the color of the prepared ingredients is uniform and free of variegation. 4. Coating materials. 5. Curing.
