After 18 months of continuous operation, the plates retained over 90% of their original thickness, whereas competing ceramic plates had degraded by more than 40% within just 10 months. These results highlight the superior longevity of high-grade silicon carbide seals, which not only reduce maintenance frequency but also minimize production downtime and raw material waste. Furthermore, the material’s resistance to chemical attack ensures consistent performance in aggressive environments—such as those involving sulfuric acid, chlorine compounds, or alkaline solutions—where other materials would corrode rapidly. For instance, a chemical processing plant in Zhejiang reported a 75% reduction in seal failure incidents after switching to Fuyang Qinzhiyu’s Type B convex ring seals, which demonstrated excellent resistance to both acidic and basic media. These documented cases illustrate that investing in high-performance silicon carbide seals is not merely about upfront cost, but about long-term operational efficiency, safety, and sustainability. As industries push toward higher automation and longer equipment life cycles, the durability and wear resistance of silicon carbide seals will remain a decisive factor in selecting reliable sealing technologies.--- 4.

--- Understanding Disc Oil Separators ---• What is a Disc Oil Separator?:A disc oil separator is a high-efficiency centrifugal separation device designed to remove solid impurities and water from oils, particularly in industrial and food-grade applications. It operates on the principle of centrifugal force, where a mixture of oil, water, and solids is fed into a rotating drum containing a stack of conical discs. The differing densities of the components cause them to separate based on their specific gravity—lighter substances like clean oil move toward the center, while heavier contaminants such as water and sludge are pushed outward. This technology is widely used in the edible oil, pharmaceutical, dairy, marine, and petrochemical industries. For example, Juneng Machinery’s DBY313 continuous disc stack centrifuge has been successfully deployed in a major Chinese vegetable oil processing plant, where it achieved a 99.8% purity rate in refined sunflower oil, reducing downstream filtration costs by over 40%. The system operates continuously with minimal downtime, thanks to its robust design and automatic cleaning capabilities.
