The three control modes of automatic self-cleaning filter are divided into: pressure difference control, manual control and timing control.
1. Pressure difference control: the control system compares the system pressure difference with the user-set pressure difference in real time. When the system pressure difference reaches the set pressure difference, the filter is also cleaned and discharged. When the blowdown time is up, the cleaning is stopped and the system is restored to its initial state, ready for the next filtration process.
2.Manual control: the manual/automatic selection switch on the operation panel to the manual position, filter blowdown.
3.Timing control: regular cleaning blowdown, can be set for 2-24 hours of action. When the timing time is up, the electric actuator opens the blowdown valve, and the filter carries out blowdown for 30-60 seconds. Then the electric actuator will turn to the butterfly valve and rotate 90° to block the filter cylinder, change the water flow path, and carry out backwash blowdown for 30-60 seconds. The steering butterfly valve is reset, continue to drain for 3-5 seconds, and then close the drain outlet.
Automatic self-cleaning filter technology features
1. Simple design structure, small footprint;
2. Short reverse cleaning time, small pressure loss, less sewage consumption, not more than 1% of the total flow;
3. High filtration precision, suitable for all kinds of water quality;
4. Intelligent control system (PLC, PAC) control, high degree of automation, can realize remote control;
5. Equipped with motor overload protection, can be very good protection motor;
6. Cleaning sewage uninterrupted water supply, without bypass characteristics;
7. Strong maintainability, easy to install and disassemble;
8. The connection mode with the user pipeline is flange connection, and the flange adopts national standard flange with strong universality;
9. Long service life, easy maintenance.
The above is the three control modes of automatic self-cleaning filter introduced by Aite environmental protection. I hope you can have a further understanding of automatic self-cleaning filter after reading it.
