Automatic Sucking Self-Cleaning Water Filter

Automatic Sucking Self-Cleaning Water Filter (FST-ASF-06/08/10/12/14/16):

Production describle:

1.Principle of Operation:

The filter element of electric suction filter adopts high strength sintered screen and automatically cleans filter element by pressure difference control and timing control. When the impurity accumulates on the surface of the filter core, the pressure difference between inlet and outlet increases to a set value, or the timer reaches the preset time, the electric control box sends out a signal to drive the backwashing mechanism. When the inlet of the backwash sucker is directly opposite to the inlet of the filter, the drain valve is opened, and the system releases the pressure and drains, and a negative pressure area with a relative pressure lower than the water pressure outside the filter element appears inside the sucker and the filter core. The net circulating water is forced to flow into the inner side of the filter core from the outside of the filter core, and the impurity particles adsorbed on the inner wall of the filter core flow with water into the sucker and discharge from the drain valve. 

During the whole self-cleaning process, the filtered water continues to flow out from the outlet. The electronic control system controls the self-cleaning process of the electric automatic cleaning screen filter by the differential pressure meter. If the pressure difference does not change after a self-cleaning cycle, the second self-cleaning will take place in 30 seconds. Electronic control system installed manual cleaning press twist to facilitate manual operation.
