"Research on the 160M3 Large-Scale Inflatable Mechanical Agitation Flotation Machine" is a key component of China's national science and technology research plan during the Tenth Five-Year Period. After years of dedicated effort, the Beijing Mining and Metallurgical Research Institute and Jinchuan Group Co., Ltd. have successfully developed the "160M3 Large Inflatable Mechanical Stirring Flotation Machine" and completed its industrial application test with great success. Recently, the China Nonferrous Metals Industry Association organized a technical evaluation to assess the achievement. Experts carefully reviewed the technical documentation, listened to detailed reports, and engaged in in-depth discussions. Following this thorough examination, the appraisal committee unanimously concluded that the equipment's overall performance has reached international advanced standards, with notable innovations in several areas: 1) The impeller-stator assembly features a unique design. The impeller uses a high-number of backward-curved blades, providing a large circulation flow with low pressure, ensuring sufficient suspension of slurry and even distribution of ore particles. The stator is designed with low-damping direct suspension, offering stable radial flow. 2) The machine incorporates a dual foam tank and dual push bubble cone structure. The inner foam tank helps to efficiently discharge flotation froth, reducing the conveying distance and increasing the thickness of the froth layer, which contributes to a more stable flotation process. 3) The pre-distribution directional air distributor is distinctive, ensuring uniform air dispersion and a rational flow path for the aerated slurry mixture. This enhances bubble surface area and significantly improves flotation efficiency. 4) The system allows for automatic control of slurry level and aeration rate, making operation convenient, stable, and efficient, with notable energy-saving benefits. Moreover, the research has enriched and improved the scaling theory for large flotation machines, laying a solid theoretical and practical foundation for the optimization of future flotation equipment and enhancing overall reliability. The successful development of this equipment marks a significant milestone, demonstrating that China's capabilities in producing ultra-large-scale mineral processing equipment now rank among the world's best. It has greatly enhanced China's ability to develop advanced mining equipment. This achievement plays a crucial role in advancing the modernization of Chinese mines, improving resource utilization, and strengthening global market competitiveness. Experts strongly recommend accelerating the promotion and application of this technology, aiming to develop a full series of equipment tailored to the needs of Chinese mines as soon as possible.

Submersible Pump Bushings & Shaft Sleeves

Submersible Pump Bushings & Shaft Sleeves

Our Submersible Pump Bushings & Shaft Sleeves are essential Components designed for use in submersible electric pumps (ESP), downhole pump systems, and other industrial fluid pumping applications. These components are engineered to protect critical rotating parts such as the pump shaft and motor, extending the life of the pump and ensuring smooth, efficient operation in harsh environments.

Submersible pump bushings and shaft sleeves play a crucial role in protecting the pump shaft from wear, corrosion, and abrasion caused by continuous rotation and exposure to aggressive fluids. Typically made from high-performance materials such as tungsten carbide, ceramic, or stainless steel, these parts offer excellent durability and resistance to extreme conditions, including high pressures, abrasive particles, and chemical corrosion.

  • Bushings serve as bearing elements that support and guide the pump shaft within the pump housing, reducing friction and ensuring proper alignment.
  • Shaft Sleeves cover the pump shaft itself, protecting it from direct contact with abrasive or corrosive fluids, thus reducing the likelihood of damage and increasing the operational lifespan of the pump.
