The core methods to solve the wear of the overflow parts of the slurry pump include: using high-performance wear-resistant materials, applying on-site rapid repair technology, and implementing intelligent monitoring and early warning systems.
Slurry pumps are widely used in industries such as mining, metallurgy, and power to transport corrosive slurries containing solid particles. Their flow-through components (such as impellers, protective plates, and volutes) are subjected to a combination of erosion, cavitation, and chemical corrosion for a long time, resulting in shortened lifespan, frequent shutdowns, and high maintenance costs. The traditional replacement method is not only expensive, but also prone to production interruption. Therefore, the industry is shifting from passive maintenance to active protection and predictive maintenance.
Classification of main solutions
1. On site rapid repair technology
Using carbon nanopolymer or epoxy resin composite materials for online repair without dismantling equipment, significantly reducing downtime.
2. Upgrade wear-resistant materials
Choosing materials that are more wear-resistant is the fundamental way to extend the lifespan of overcurrent components.
3. Intelligent monitoring and predictive maintenance
By combining vibration sensors with spectrum analysis, the wear status can be identified in real time, shifting from "regular replacement" to "on-demand maintenance".
4. Structural optimization and casting process improvement
Using the disappearing die negative die-casting infiltration process to manufacture surface composite material flow parts, ceramic particles are tightly combined with the substrate to form a strong and wear-resistant layer, which increases the service life by more than twice and reduces costs.
Flow field simulation (CFD) can be used to analyze pressure and velocity distribution, optimize impeller and volute design, reduce cavitation and local high-speed erosion areas.
Overall, the best strategy should combine multiple means:
For worn parts: prioritize on-site repair using carbon nano polymer materials to save time and cost;
When purchasing or replacing: choose high chromium alloy+ceramic composite material or gradient composite wear-resistant plate (such as HRC62-65 hardness) to extend the service life;
In terms of operational management, deploying vibration monitoring systems to achieve early warning and promote a shift from passive maintenance to predictive maintenance.
