The water to be treated by the brush type self-cleaning filter produced by Shanghai Jiuching enters the body from the inlet, and the impurities in the water are deposited on the stainless steel screen, thus generating a differential pressure. When the pressure difference reaches the set value, the electric controller will signal the hydraulic control valve and drive motor to trigger the following actions: the motor will drive the brush to rotate and clean the filter element, while the control valve will be opened for discharging, the whole cleaning process will only last for tens of seconds. When the cleaning process is finished, the control valve is closed, the motor stops rotating and the system returns to its initial state and starts to the next filtration process. After the brush type self-cleaning filter is installed, the technician will debug it, set the filtering time and cleaning conversion time, the water to be treated will enter the body from the water inlet, the brush type self-cleaning filter will start to work normally, when the preset cleaning time is reached, the electric controller will give the signal to the hydraulic control valve and the driving motor, which will trigger the following actions: the motor will drive the brush to rotate and clean the filter element, while the control valve will open for discharging. When the cleaning is finished, the control valve is closed, the motor stops rotating and the system returns to its initial state and starts to the next filtering process.

Brush type self-cleaning filter operating characteristics.

1、Brush self-cleaning filter adopts high-strength 316L stainless steel (or alloy) sintered mesh of up to 2 microns, which is backwashed by 2.0Mpa high pressure, so that the screen is cleaned quickly and cleanly, and can be restored to its initial state with long service life.

2、The brush type self-cleaning filter wise control differential pressure filter has automatic retrieval function, and through the various data retrieved automatically realize the drainage and high pressure backwashing function, which can cope with the unstable water quality fluctuation, fully automatic operation without manual intervention.

3、Brush self-cleaning filter control system is responsive and has multiple setting functions of differential pressure, time and manual, which can flexibly adjust the backwashing differential pressure or time setting value according to different water sources and filtration degrees.

4、backwashing without interrupting the normal water production, continuous operation, stable and reliable.
