Working principle
When water flows into the filter through the water inlet ,larger particles of impurities will be intercepted by corse screen,then it reaches the fine screen.During the filtering process , the dirt and impurities in water,then form a filtration impurity will gradually accumulate fine screen ,as the impurity layer is stacked on the inside of the fine filterscreen,therefore in the fine filter, differential pressure will form between the inside and outer side of the screen.
When pressure differential reaches the presetted pressure,it will start the automatic cleaning ,during this processing water supplying is constant ,cleaning valve opens,water pressure in cleaning chamber and pollution absorption device drops sharply,under the action of pressure difference between the filter cartridge and the sewage suction pipe ,it will a suction power will generate between sewage suction pipe and the cleaning chamber through nozzle ,sewage suction process is finished.meanwhile,the electric motor drives the sewage suction pipe to start a helical movement along the axial.the combine of sewage suction device axial motion and rotary motion will completely clean the inside surface of the screen,the flushing process will last 40 seconds to 1 minutes.Drain valve will be closed at the end of cleaning,filter started to prepare a next cleaning cycle.
Cleaning system
When the water flows through the filter, impurities will gradually accumulates in the surface of its screen, results in the water pressure difference between the water inlet pipe and outlet pipe. When the differential pressure reaches a preset value 0.05MP, backwashing starts work. Sucking scanner driven by motor, and do spiral motion around the screen, on the scanner suction by sucking impurity particle movement, through the sewage discharge valve, but does not contact the screen, the cleaning process for 30-60 seconds. According to the requirement of the water quality, suction type (500-30 micron) a variety of filtering accuracy.
Control mode
The filter is equipped with pressure difference switch and integrated controller. When water pressure difference reaches the preset value, the differential pressure switch will start, electric control system enter into the back wash process. The back wash time can be preset by the integrated controller.
Characteristic
1. The equipment structure is compact, sturdy and reliable
2. Back wash water consumption is small, and the required water pressure is low.
3. Filtering has high precision, is suitable for various water quality
4. The pressure drop is small while back wash, does not affect the normal water supply.
