Filter water from the inlet into the body to be treated, the impurities in the water deposit on the stainless steel filter, the resulting differential pressure. By differential pressure switch monitoring
Filter device water mouth pressure poor changes, dang pressure poor reached set value Shi, electric control device to hydraulic control valve, drive motor signal, raised following action: electric machine led brush rotating, on filter for cleaning, while control valve open for sewage, whole cleaning process just continued number 10 seconds, dang cleaning end Shi, close control valve, motor stop turned, system recovery to its initial state, began into next filter process.
