1. The raw water quality of the Cast Iron Centrifugal Pumps is unstable and frequently fluctuates, resulting in excessive particulate matter entering the filter element, resulting in a shortened cycle;
2. The pretreatment operation of stainless steel filter element is poor. The flocculant and scale inhibitor added by pretreatment are incompatible with each other or do not match the water source. The formed sticky substance adheres to the surface of the filter element, resulting in a decrease in the effective filtration area of the filter element, resulting in a filter element. Frequent replacement;
3. The quality of the Bronze Centrifugal Water Pump is not good. The inner and outer diameters of the filter element with poor quality are basically the same. In fact, only the outer layer plays the intercepting role, and the filter element of the good filter element is gradually reduced from the outside to the inside. The inner layer filtration precision is 5±0.5μm. The amount of pollution is larger, and the long time used can ensure the quality of the effluent is qualified.
