automatic backwash water filter
Product introduction
Automatic backwashing filter is applicable for all kinds of water supply systems, process water system and industrial cooling water, especially for the 24-hour-running system. It could filter the mechanical impurity in the water and make sure the safe and reliable running of the system and the equipment.
Structure and work principle
Automatic backwashing filter is made up of the high quality carbon steel cartridge, stainless steel wedge strainer of special structure, electric actuating mechanism and drainage device. When the filter works, the electric actuating mechanism will lead the butterfly valve to open, the water flow gets into the filter through the entrance, after the filtering with the strainer to the exit. When the filter requires the drainage, the butterfly valve will close and the drainage valve will open. After the filtering with the first half of the strainer, part of the water flows into the system through the exit. The rest water will flow from the outer side of the second half of the strainer to the inner side. And it is discharged from the drainage exit. It is with the use of automatic backwashing of the strainer Then during the whole washing process the system could run normally without stop.
Work pressure: Less than 1.0MPa
Work temperature: Less than 100Centigrate
Pressure loss: Less than0.015MPa
Filtering precision: D=1.0mm
Other: Work pressure, filtering precision and the specification could be manufactured according to the special requirement of the customer. The connection dimension of flange will be according to GB-9119.9-88.
Technical feature
1. High filtering precision and stable water quality.
2. Automatic backwashing is realized with the self retrieval and response function, it could deal with the unstable water quality fluctuation without
Manual intervention.
3. Sensitive response and precise operation of the control system, with the double setting function of pressure difference and time. The
Backwashing pressure difference and the time could be adjusted flexibly according to the different water source and filtering precision.
4. Successive water production during the backwashing, successive running, stable and reliable.
5. Taking short time to backwash, the water consumption of backwashing is only 0.001- 0.002% of lhe normal water production, saving the waler,
Power and energy.
6. The structure design is compact and reasonable. It occupies small area. It is convenient to install and move.

Structure and working principle
Automatic backwashing filter is made up of the high quality carbon steel or SS filter housing, special structure stainless steel wedge screen, electric actuating mechanism and drainage device. When the filter start working, the electric actuating mechanism will lead the butterfly valve to open, the flowing water gets into the filter through the entrance, it reaches the outlet after filtered by screen.When the filter needs to discharge drainage, the butterfly valve will close and the drainage valve will open. The flowing water filtered by front half part of the screen, part of the water flows into the filter through the water outlet.
The remaining water will flow into internal part of the second half screen section from the screen outside .then it is discharged out from the drain outfall. It acted as automatic backwashing on the filter screen, Therefore the filter could run normally without stop during the whole washing process.
Other techanical parameters sheet.
work pressure: less than 1.0MPa
work temperature: less than 100 Centigrate
Pressure loss: less than0.015MPa
Filtering precision: 300-100 micron
Other configurations: working pressure, filtration degree and the filter specification could be manufactured based on buyers' special requirement. The flange connection dimension is according to GB-9119.9-88.
Technical characteristics:
1. High filtration degree and stable good quality water output.
2. Automatic backwashing is realized by the self retrieval and response function, it could deal with the unstable water quality fluctuation without manual intervention.
3. the control system is of sensitive response and precise operation, two different setting : pressure difference and time. The backwashing pressure difference and the time could be adjusted flexibly according to the different water source and filtration degree.
4. Successive water production during the backwashing process, continuous, stable and reliable working.
5.short time for backwash, the water consumption of backwashing is only 0.001-0.002% of lhe normal water production, saving the water,power and energy.
6. compact and scientific structure design. small occupation,convenient installation and moving.
