1. Liquid-liquid system is used to prevent the separation, so that the temperature uniformity. The solid-liquid system is used to prevent the settlement of solids.
2. Mainly used in the circulation of fluids, due to the same displacement, the than leaf-type power consumption less, operating costs are low, so the use of axial blades more.
3. Also used for high viscosity fluid stirring, to promote the upper and lower exchange of fluid, replace the high price of the spiral belt impeller, can get good results.
