2. Adopt the patented internal mechanical structure to realize the real high-pressure backwashing function. The combination of external high-pressure backwashing of the filter screen and internal self-suction sewage discharge can easily and thoroughly remove the impurities intercepted by the filter screen, and there is no dead angle in cleaning, the flow rate is attenuated, the filtration efficiency is guaranteed, and the service life is long.
3. The differential pressure signal of water filter cleaning is transmitted by differential pressure transmitter, which overcomes the shortcoming of large error of differential pressure switch.
4. The transmission device of the water filter is built-in, sealed, isolated from the over-current parts, and designed with tripping protection function to prevent the motor or body parts from being damaged, and the operation is stable and reliable.
5. The sewage outlet is sealed by hydraulic pressure, and there is no need for solenoid valves or other fragile seals, which is simple and practical.
6. The inlet and outlet flanges of the water filter are designed as movable structure, and the direction of screw holes can be adjusted at will, which is convenient for on-site installation.
7. Special non-toxic anti-corrosion materials are used for internal corrosion protection, which has good weather resistance, acid and alkali resistance, salt fog resistance and mildew resistance.
8. The filter adopts integrated control mode, which can realize remote control.
