DSX-C Automatic Self Cleaning Filters-Hydraulic (Environmech Sdn Bhd) Malaysia

Working Principle
DSX-C series filter is fitted with a front primary strainer to avoid sucking nozzle blocked.
The water flows into the primary strainer through the inlet. The bigger particles were intercepted in the outer of the primary strainer . The filtered water flows towards the two-stage fine strainer then the smaller impurity particles were intercepted inside the fine strainer. The filtered water flows out through water outlet .
The pressure differential will generate once the dirts accumulated on the inwall of fine.
When the pressure difference reach to the pre-set value, the controller will send out indicating signal of opening blowoff valve and starting scanner,sucking nozzle.
Then the system start decompressing& blow off dirts, a stream of strong backwash water generated and flow towards atmosphere through blowoff valve. It generates suctions inside sucking nozzle.The sucking nozzle removes the inwall dirts by means of suction and eliminates the dirts through blowoff valve.The scanner keeps rotary and axial moving simultaneously to insure the
cleanliness of strainer.
It'll take 8s~25s for one self-cleaning cycle without interruption of water flow and the lossof water is few. Once selfcleaning process finished, the valve closed and the scanner moved back automatically . The next self-cleaning cycle will start according to the system programming and repeat the above steps.
