PLC control automatic self cleaning filter

The automatic self cleaning filter is widely used in water treatment, paint and food grade industries. When the product enters the self-cleaning filter from the inlet, the impurities are blocked on the inner wall of the filter element, and the filtered clean product flows out from the outlet. When the pressure difference of the self-cleaning filter reaches the preset value or reaches the cleaning time or manual operated, the filter will start the self-cleaning process. The whole self-cleaning process includes two steps: open the automatic drain valve on the self-cleaning filter; the motor drives the cleaning brush in the filter screen, the impurities blocked by the filter screen are discharged from the drain valve, and the system continuously flows during cleaning. The entire operation process of the self-cleaning filter is controlled by a PLC screen control pannel. The control mode can choose differential pressure, time, manual.
