Maxcase #11 - Mining & Mineral Process: Recovery and modeling of the circumference of a liquid ring vacuum pump cover damaged by continuous operational use.
✳️ Challenge:
The equipment was found to have diametrical wear with a maximum depth of 18 mm, on around 50% of the perimeter.
🛠️ Scope of Activities:
- Surface preparation with sandblasting and electric sander to produce a rough surface;
- Application of the first layer of high-adhesion ceramic polymer Maxceramic 1511 for reconstruction;
- Assembling a template for modeling the damaged circumference;
- Carrying out two more coating applications, molding the polymer according to the template.
✅Solution:
Three applications of the coating were carried out, molding the polymer using a template. Due to the extreme damage caused by abrasion, completely incapacitating it from operating, surface preparation has become even more crucial for the successful fixation of the Maxceramic 1511 coating.
✅✅ Conclusions:
The recovery of the Nash pump cover was carried out successfully, without any anomalies, where after the curing time the template was removed and released for use.
