The water to be treated by the filter enters the body through the water inlet, and impurities in the water are deposited on the stainless steel filter screen, thereby generating a pressure difference. Monitoring the pressure through the differential pressure switch
The pressure difference of the water outlet of the filter changes. When the pressure difference reaches the set value, the electric controller feeds the hydraulic control valve and drives the motor signal, causing the following actions: the motor drives the brush to rotate, clean the filter element, and at the same time, the control valve is opened to discharge sewage. The entire cleaning process only needs to last for tens of seconds. When the cleaning is completed, the control valve is closed, the motor stops rotating, the system returns to its initial state, and the next filtration process is started.
After the equipment is installed, the technicians will debug and set the filtration time and the cleaning conversion time. The water to be treated enters the body through the water inlet, the filter starts to work normally, and when the preset cleaning time is reached, the electric control valve of the water supply control valve 4. Drive the motor signal to trigger the following actions: the motor drives the brush to rotate, clean the filter element, and at the same time the control valve opens to drain the sewage. The entire cleaning process only needs to last for tens of seconds. When the cleaning is completed, the control valve is closed and the motor stops rotating. The system returns to its initial state and begins to enter the next filtration process.
The inside of the filter housing is mainly composed of a coarse filter screen, a fine filter screen, a sewage suction pipe, a stainless steel brush or a stainless steel suction nozzle, a sealing ring, a corrosion-resistant coating, a rotating shaft, etc.
