Horizontal centrifugal pump suitable for transporting phosphate
At ordinary times, attention should be paid to the rationality in the selection of phosphoric acid pump. The so-called reasonable selection of phosphate pump is to comprehensively consider the comprehensive technical and economic indicators such as the investment and operation cost of phosphoric acid pump unit and phosphoric acid pumping station, so as to make it in line with the principles of economy and application. The principle of acid resistance of most phosphate pumps is mainly due to the material of the pump. generally, phosphate pumps use non-metallic materials as the overflowing parts of the pump, such as "polyethylene, polypropylene, polyperfluoroethylene propylene, etc.", in which polyperfluoroethylene propylene (PVDF) is one of the good acid-resistant materials, which can basically resist the corrosion of any acid medium, so it is called plastic king.
It is necessary to meet the requirements of flow rate and head, that is, the operation point of the phosphoric acid pump (the intersection of the device characteristic curve and the performance curve of the phosphoric acid pump) is often kept in the interval, which saves power and is not easy to damage the parts.
