Quartz sand filter
big effective filtering area
good sealing effect
prevent side leakage

 

 

 

 

 working principle:

 1.By the entrance into the water, the first after thick mesh filter out larger particles, and then reach fine mesh impurities. In the filtering process, fine mesh gradually accumulated dirt and impurities in water, forming filtering impurities layer, because impurities accumulated in fine of filter layer, so in fine mesh medial side of internal and external form one differential pressure.
When filter pressure differential achieve default value, will begin to automatic cleaning process, during which no depletion, water supplies, clean room cleaning valves open and absorbing unclean device for internal pressure dropped substantially, suction filter canister and dirt by the pressure difference and suction pipe tube and rinsing room dirt between produced by suction nozzle, forming a suck a suction decontamination process. Meanwhile, electric motor drive sucked unclean tube along the axial do spiral movement. Suck unclean device axial movement and the combination of rotation movement within the entire mesh surface completely clean. The whole flushing process just tens of seconds. Drain valve closes in cleaning end. Filter began to prepare for the next flush cycle.

2. Processed by the water, the water enters the water entry in stainless steel mesh impurities deposition, the resulting differential pressure. Through the differential pressure switch monitoring in shuikou differential pressure changes, when the pressure difference control device to set value, to our hydraulic control valves, drive motor signals, cause the following actions: motor driving brushes spin, cleaning, and at the same time to filter for drainage, the control valve opened the cleaning process just continued dozens of seconds, when cleaning, shut off the valve end, motor stop, the system restore to its initial condition, began to enter the next filtration process.
Equipment installation, debugging by technicians, setting filtering time and cleaning conversion time, processed by the water enters the water entry, a filter began to work normally, when they reach the preset cleaning time, electric control device for hydraulic control valves, drive motor signals, cause the following actions: motor driving brushes spin, cleaning, and at the same time to filter for drainage, the control valve opened the cleaning process just continued dozens of seconds, when cleaning, shut off the valve end, motor stop, the system restore to its initial condition, began to enter the next filtration process.
