Self-cleaning filter the transversal partition inside the tank divides it into two upper and lower chambers. The upper part is the clear water area and the lower part is the muddy water area. The two are completely separated. A number of stainless steel filter columns are installed on the transversal partition. The raw water to be treated enters the muddy water area through the inlet, and enters the inner cavity of the filter column from the bottom to the top through the water distribution holes on the transverse partition. The impurities larger than the gap of the filter column are intercepted, and the clear water passes through the gap and enters the clear water area. All the liquids filtered by the filter column converge in the clear water area and then flow out from the outlet. When impurities accumulate to a certain thickness in the filter column, it will cause a pressure difference between the clear water zone and the muddy water zone. At this time, the backwash filter can be automatically controlled by the differential pressure controller to start the backwash mechanism, or manually start the backwash system ，Remove the filter residue

1. The filter element has a large pressure bearing capacity: the filter flows outward from the center of the filter element, so the filter element can carry a higher pressure load.

2. The no-load resistance is small, and the self-cleaning filter backwash water volume is small: the flow of water is unobstructed and the resistance is small. When the target suspended solids concentration in the water to be filtered is ≤20mg/L, the backwash water consumption accounts for the percentage of the large filtered water volume≯ 1%.

   3. Reliable operation and simple maintenance: The unique spindle self-sealing mechanism enables the spindle to automatically compensate for the seal, and it will not leak during long- term operation, and generally does not require routine maintenance.

Filtering of bearing cooling water, generator oil cooling water, industrial cooling water, sealing water, dust removal spray water and boiler water supply

Rugged and durable; 9. The unique cleaning design realizes low load, low water head, and even discharge of the backwash filter; 10. The direction of the electric control box panel can be adjusted at will to meet the user's requirements. The fully automatic backwash filter can make industrial sewage meet the national wastewater discharge standards, which can effectively protect the environment, and at the same time, it can also treat the sewage to a standard that can be reused. This not only solves the problem of sewage discharge. d. Fully automatic recoil sewage filter program control: various parameters of the system can be set according to the actual situation of the user on-site. e. The advanced control system of the backwash filter: the control system has a high degree of control, and its working mode and operating state can be adjusted according to different water quality, and the filter is self-cleaning to improve its ability to adapt to water quality. f. Convenient control method of backwash filter: pressure difference/time control at the same time or separately. The dirt on the inner wall of the fine filter screen is sucked by the suction nozzle, and it flows into the hydraulic motor chamber by the hydraulic motor, and is discharged by the sewage valve to form a dirt suction process. When water flows through the hydraulic motor, it drives the sewage suction pipe to rotate. The hydraulic cylinder piston drives the sewage suction pipe to move axially. The sewage suction assembly cleans the entire inner surface of the filter screen completely through the combination of axial movement and rotation. The entire cleaning process will last for tens of seconds. No need to replace. 7. Long service life. 8. It can be applied to different raw water quality and water requirements. 9. Few wearing parts, no consumables, low operating cost, simple operation and management. 10. Automatic anti-cleaning and continuous flow. When selecting the filter type, 5. The relevant physics of the filter medium, self-cleaning filter 1. Check whether the pipeline installation is correct before the system runs. 2. Flush the system pipeline. At this time, the water inlet and outlet valves of the equipment must be closed, and the bypass valve must be opened. 3. After the check is correct, open the inlet valve, outlet valve, close the bypass valve and drain valve
