Principle Of Water Filter

- Apr 20, 2019-

Filter core using high-strength wedge filter, through the pressure difference control, timing control automatic cleaning filter.

When the impurities in the filter accumulate in the filter cartridge

Water filter

Water filter When the surface causes the import and export pressure difference to increase to the set value, or when the timer reaches the preset time, the electric control box sends a signal to drive the backwash mechanism.


When the backwash suction cup inlet and filter inlet is right, the sewage valve opens, at this time the system pressure drainage, suction cup and the inside of the filter cartridge appears a relative pressure below the external pressure of the filter cartridge negative pressure zone, forcing part of the net circulating water from the outside of the filter cartridge into the inside of the filter cartridge, adsorption on the inner wall of the filter The specially designed filter causes a spray effect inside the filter cartridge, and any impurities will be washed away from the smooth inner wall.

When the filter import and export pressure difference returns to normal or the timer set time ends, the whole process, the material is not cut off, anti-washing water consumption is less, to achieve continuous, automated production. After the installation of the equipment, by the technical personnel to debug, set the filtration time and cleaning conversion time, to be treated water from the inlet into the body, the filter began to work normally, when the preset cleaning time, the electronic controller to the hydraulic control valve, drive motor signal, triggered the following actions: The electric machine Drive brush rotation, the filter cartridge cleaning, At the same time the control valve opens for discharge, the entire cleaning process only lasts a few 10 seconds, when the cleaning is over, close the control valve, the motor stops turning, the system reverts to its initial state, began to enter the next filtration process.
