Fluid & Seal Technology

CFD simulation has been able to obtain the details of the internal flow field of turbomachinery within the range of engineering accuracy, and can also truly reflect the complex internal flow phenomena, and even can predict new phenomena that have not been found in theoretical analysis and experimental research. SUNKAIER prototype performance test with CFD method by computer, and can well in drawing design stage, to predict fluid mechanical performance and internal flow vortex, secondary flow, boundary layer separation, drafting, as well as the blade flutter phenomenon, striving to fault hidden trouble may occur in the design stage, to a certain extent, to replace the test, in order to reduce the cost and shorten the development cycle. SUNKAIER adopts CFD simulation technology to better design the impeller, so the maximum fluid requirements are met. The main recommended SUNKAIER impeller is as follows:

R763 Gas Dispersion Impellers:

utilize a unique blade design that pushes a greater amount of fluid volume, reducing system drag and making power draws more consistent.

R800 Series Retreat Curve Impellers:

are excellent uniformity of dispersion in the tank and fluidization of material in solid-liquid mixing and slurry mixing under low-revolution and low dynamic power conditions. Their proximity to the tank bottom makes them less susceptible to liquid surface fluctuation and ensures particle uniformity. Shearing force control is achieved by controlling pressure fields, such as the combination of the impellers and static blades. The unique profile is the result of research into pressure distribution in the tank serving as a agitator. It enables a large circulation flow pattern and an extremely high discharge capability that cannot be expected even from large and wide blades. At the same time, the power requirement is low.
