ELSeries Automatio Self Cleaning Strainer

Principle of Operation

Filtration Process: the media flows into strainer from inlet and through the screen, then the clean water flows out from outlet. Impurities accumulate to form the filter cakes on the inner surface of screens, at the same time, the pressure difference between the inner of screens and the exterior of screens is formed gradually.

Self-cleaning Process: when the pressure difference reaches default value, the signal is sent to PLC(programme logic control) by differential pressure switch; when PLC drives motor, the shaft begins to rotate, then the rotating brush can clean the impurities away from the inner surface of screens. At the same time, drain valve is opened by PLC, the impurities are discharged from the drain valve by system inner pressure.
