When conveying large particles of varying sphericity in deep sea mining pumps, there is a risk of clogging or clogging. Pump systems must be designed to effectively meet these challenges. Here are some considerations for mitigating blocking issues: 1. Particle size and sphericity: Knowledge of the particle size range and their sphericity is critical to designing a proper pump system. Different particle sizes and shapes may have different flow behavior and tendencies to cause clogging. It is important to analyze the particle size distribution and properties of the particles being pumped to determine pump functionality and limitations. 2. Selection of pump: It is very important to select a pump specially designed for handling large particles with different sphericity. Consider using a pump with larger openings or channels to accommodate particle size and shape variations. Slurry pumps or pumps with open impellers and larger clearances may be better suited for handling irregularly shaped particles. 3. Material selection: When handling large particles, it is critical to select a pump material that can withstand wear and corrosion. Hardened materials, such as hardened alloys or ceramic coatings, provide better wear resistance and extend pump life. Pump casings, impellers and other parts in contact with particles should be made of suitable materials to minimize the risk of clogging due to wear or material degradation. 90R075-KA-5-BB-60-R-3-C7-D-03-GBA-42-42-28 90R075KA5BB60R3C7D03GBA424228 90-R-075-KA-5-BB-60-R-3-C7-D-03-GBA-38-38-28 90R075KA5BB60R3C7D03GBA383828 90R075-KA-5-BB-60-R-3-C7-D-03-GBA-38-38-28 90R075KA5BB60R3C7D03GBA383828 90-R-075-KA-5-BB-60-P-4-C7-E-03-GBA-26-26-24 90R075KA5BB60P4C7E03GBA262624 90R075-KA-5-BB-60-P-4-C7-E-03-GBA-26-26-24 90R075KA5BB60P4C7E03GBA262624 90-R-075-KA-5-BB-60-P-3-S1-D-03-GBA-42-42-28 90R075KA5BB60P3S1D03GBA424228 90R075-KA-5-BB-60-P-3-S1-D-03-GBA-42-42-28 90R075KA5BB60P3S1D03GBA424228 90-R-075-KA-5-BB-60-L-3-C7-E-03-GBA-35-35-24 90R075KA5BB60L3C7E03GBA353524 90R075-KA-5-BB-60-L-3-C7-E-03-GBA-35-35-24 90R075KA5BB60L3C7E03GBA353524 90-R-075-KA-5-BB-60-L-3-C6-E-03-GBA-35-35-24 90R075KA5BB60L3C6E03GBA353524 90R075-KA-5-BB-60-L-3-C6-E-03-GBA-35-35-24 90R075KA5BB60L3C6E03GBA353524 90-R-075-KA-5-AB-80-S-4-S1-D-03-GBA-42-42-24 90R075KA5AB80S4S1D03GBA424224 90-R-075-KA-5-AB-80-S-4-S1-D-00-GBA-35-35-24 90R075KA5AB80S4S1D00GBA353524 90R075-KA-5-AB-80-S-4-S1-D-00-GBA-35-35-24 90R075KA5AB80S4S1D00GBA353524 90-R-075-KA-5-AB-80-S-4-C7-E-03-GBA-42-42-24 90R075KA5AB80S4C7E03GBA424224 90R075-KA-5-AB-80-S-4-C7-E-03-GBA-42-42-24 90R075KA5AB80S4C7E03GBA424224 90-R-075-KA-5-AB-80-S-4-C7-D-03-GBA-42-42-24 90R075KA5AB80S4C7D03GBA424224 90R075-KA-5-AB-80-S-4-C7-D-03-GBA-42-42-24 90R075KA5AB80S4C7D03GBA424224 90-R-075-KA-5-AB-80-S-4-C7-D-03-GBA-32-32-24 90R075KA5AB80S4C7D03GBA323224 90R075-KA-5-AB-80-S-4-C7-D-03-GBA-32-32-24 90R075KA5AB80S4C7D03GBA323224 4. Consideration of settling velocity: large particles with different sphericity may have different settling velocities in the conveying medium. It is important to consider the settling behavior of the particles and ensure that the pump system is designed to prevent settling or deposits that could lead to clogging. Sufficient fluid velocities and fluidization techniques can be employed to maintain particle suspension and prevent particle settling in the system. 5. Solid handling capacity: Deep sea mining pumps should have strong solid handling capacity. This includes features such as large solids channels, special impeller designs such as concave or vortex impellers, or built-in mechanisms to prevent clogging such as cutting or grinding mechanisms. These features help break up or pass through large particles and reduce the risk of clogging. 6. Regular Maintenance and Cleaning: Despite design considerations, it is important to perform regular maintenance and cleaning of pump systems to prevent debris or particulate buildup that can eventually lead to blockages. Inspection, flushing and cleaning procedures should be implemented as part of routine maintenance practices to ensure smooth and uninterrupted operation. 7. Screening or Classification: Implementing a screening or classification mechanism before the pump can help remove or separate oversized particles that can cause clogging. This process can be done using screens or grates that only allow particles within the desired size range to enter the pump system. This pre-screening step can significantly reduce the risk of clogging and improve the overall efficiency of the pump. 90-R-075-KA-5-AB-80-S-4-C6-D-03-GBA-35-14-30 90R075KA5AB80S4C6D03GBA351430 90R075-KA-5-AB-80-S-4-C6-D-03-GBA-35-14-30 90R075KA5AB80S4C6D03GBA351430 90-R-075-KA-5-AB-80-S-3-S1-D-03-GBA-42-42-24 90R075KA5AB80S3S1D03GBA424224 90R075-KA-5-AB-80-S-3-S1-D-03-GBA-42-42-24 90R075KA5AB80S3S1D03GBA424224 90-R-075-KA-5-AB-80-S-3-C7-D-03-GBA-42-42-24 90R075KA5AB80S3C7D03GBA424224 90R075-KA-5-AB-80-S-3-C7-D-03-GBA-42-42-24 90R075KA5AB80S3C7D03GBA424224 90-R-075-KA-5-AB-80-S-3-C7-D-00-GBA-38-38-24 90R075KA5AB80S3C7D00GBA383824 90R075-KA-5-AB-80-S-3-C7-D-00-GBA-38-38-24 90R075KA5AB80S3C7D00GBA383824 90-R-075-KA-5-AB-80-R-3-S1-D-03-GBA-35-35-24 90R075KA5AB80R3S1D03GBA353524 90R075-KA-5-AB-80-R-3-S1-D-03-GBA-35-35-24 90R075KA5AB80R3S1D03GBA353524 90-R-075-KA-5-AB-80-R-3-S1-C-03-GBA-35-35-24 90R075KA5AB80R3S1C03GBA353524 90R075-KA-5-AB-80-R-3-S1-C-03-GBA-35-35-24 90R075KA5AB80R3S1C03GBA353524 90-R-075-KA-5-AB-80-R-3-C7-D-03-GBA-21-21-24 90R075KA5AB80R3C7D03GBA212124 90R075-KA-5-AB-80-R-3-C7-D-03-GBA-21-21-24 90R075KA5AB80R3C7D03GBA212124 90-R-075-KA-5-AB-80-R-3-C6-D-03-GBA-29-29-24 90R075KA5AB80R3C6D03GBA292924 90R075-KA-5-AB-80-R-3-C6-D-03-GBA-29-29-24 90R075KA5AB80R3C6D03GBA292924 90-R-075-KA-5-AB-80-P-4-S1-D-03-GBA-35-35-24 90R075KA5AB80P4S1D03GBA353524 90R075-KA-5-AB-80-P-4-S1-D-03-GBA-35-35-24 90R075KA5AB80P4S1D03GBA353524 90-R-075-KA-5-AB-80-P-4-S1-D-03-GBA-23-23-24 90R075KA5AB80P4S1D03GBA232324 90R075-KA-5-AB-80-P-4-S1-D-03-GBA-23-23-24 90R075KA5AB80P4S1D03GBA232324 8. Flow rate and pressure monitoring: Monitoring flow rate and pressure within a pump system can provide valuable insight into potential clogging conditions. By continuously monitoring these parameters, any changes or fluctuations that may indicate a blockage can be detected early on. An alarm system can be integrated to alert the operator when flow conditions deviate from expected ranges, enabling rapid action to prevent or resolve blockages. 9. Flushing and backflushing: Flushing or backflushing the pump system with water or a suitable flushing medium can help remove accumulated particles or blockages. The procedure involves reversing the direction of flow or introducing a high-pressure flush to clear the channels and restore normal flow. Regular flushing or backflushing as part of a maintenance program can prevent material buildup and minimize the risk of clogging. 10. Computational Fluid Dynamics (CFD) Modeling: Utilizing CFD modeling can help optimize the design of pump systems and predict potential areas prone to clogging. By simulating flow behavior and particle trajectories, engineers can identify critical areas, such as areas of high velocity or particle accumulation, and make necessary design modifications to minimize the risk of clogging. 90-R-075-KA-5-AB-80-P-4-C7-D-03-GBA-42-42-24 90R075KA5AB80P4C7D03GBA424224 90R075-KA-5-AB-80-P-4-C7-D-03-GBA-42-42-24 90R075KA5AB80P4C7D03GBA424224 90-R-075-KA-5-AB-80-P-3-C7-D-03-GBA-42-42-24 90R075KA5AB80P3C7D03GBA424224 90R075-KA-5-AB-80-P-3-C7-D-03-GBA-42-42-24 90R075KA5AB80P3C7D03GBA424224 90-R-075-KA-5-AB-80-P-3-C7-D-03-GBA-35-35-24 90R075KA5AB80P3C7D03GBA353524 90R075-KA-5-AB-80-P-3-C7-D-03-GBA-35-35-24 90R075KA5AB80P3C7D03GBA353524 90-R-075-KA-5-AB-80-P-3-C6-C-03-GBA-42-42-24 90R075KA5AB80P3C6C03GBA424224 90R075-KA-5-AB-80-P-3-C6-C-03-GBA-42-42-24 90R075KA5AB80P3C6C03GBA424224 90-R-075-KA-5-AB-80-L-4-S1-D-05-GBA-20-20-24 90R075KA5AB80L4S1D05GBA202024 90R075-KA-5-AB-80-L-4-S1-D-05-GBA-20-20-24 90R075KA5AB80L4S1D05GBA202024 90-R-075-KA-5-AB-80-L-4-C7-D-03-GBA-30-30-24 90R075KA5AB80L4C7D03GBA303024 90R075-KA-5-AB-80-L-4-C7-D-03-GBA-30-30-24 90R075KA5AB80L4C7D03GBA303024 90-R-075-KA-5-AB-80-L-3-S1-D-03-GBA-35-14-24 90R075KA5AB80L3S1D03GBA351424 90-R-075-KA-5-AB-80-L-3-S1-D-00-GBA-42-42-24 90R075KA5AB80L3S1D00GBA424224 90-R-075-KA-5-AB-80-L-3-C7-E-03-GBA-35-35-24 90R075KA5AB80L3C7E03GBA353524 90R075-KA-5-AB-80-L-3-C7-E-03-GBA-35-35-24 90R075KA5AB80L3C7E03GBA353524 90-R-075-KA-5-AB-80-L-3-C7-D-04-GBA-42-42-24 90R075KA5AB80L3C7D04GBA424224 90R075-KA-5-AB-80-L-3-C7-D-04-GBA-42-42-24 90R075KA5AB80L3C7D04GBA424224 90-R-075-KA-5-AB-60-S-4-C6-E-03-GBA-23-23-24 90R075KA5AB60S4C6E03GBA232324 90R075-KA-5-AB-60-S-4-C6-E-03-GBA-23-23-24 90R075KA5AB60S4C6E03GBA232324 11. System monitoring and remote operation: Deep sea mining operations can benefit from remote monitoring and operation capabilities. Pump performance, particle behavior and flow conditions can be monitored remotely in real-time to ensure continuous operation and early detection of clogging related issues. The remote control system also enables operators to adjust pump settings or initiate cleaning routines when a clog is detected, increasing overall system reliability and minimizing downtime. 12.
