How to correct mechanical seal wear

How to correct mechanical seal wear There are two traditional methods for correcting the spindle mechanical seal bushing. Method 1: Use gouging to open the main shaft seal 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 main shaft seal bushing, use welding wire made of the same material as the mechanical seal of the kettle, control the temperature and current, and repair the welding with manual argon arc welding. The weld is about 1mm higher than the base surface of the base material. After finishing, grinding, polishing, inspection with flaw detection to avoid cracks, until the design requirements are reached. This method takes long welding time, messy skills, time-consuming and labor-consuming, deformation of the spindle and bushing is not easy to control, and high potential safety hazards. It simply constitutes a ring-shaped short-circuit shaft current and burns the bearing. Method 3: Solei Liquid Ceramics Correction Method Liquid ceramic polymer materials are 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 even in the harshest dry grinding environment. The construction process is as follows: 1. The surface of the substrate is roughened. 2. Cleaning. Use absolute ethanol and clean cotton yarn to clean the surface of the equipment. 3. Harmonious information. The seasoning must be fully mixed and evenly mixed to ensure that the color of the seasoned material is uniform and free of noise. 4. Coating information. 5. Curing.
