Working principle of circulating water filter (1)
Water enters from the inlet, first passes through the coarse strainer to remove impurities of larger particles, and then reaches the fine strainer. During the filtering process, the fine filter screen gradually accumulates dirt and impurities in the water to form a filter impurity layer. Since the impurity layer is accumulated on the inside of the fine filter screen, a pressure difference is formed on the inner and outer sides of the fine filter screen.
When the pressure difference of the filter reaches the preset value, the active cleaning process will be started. During this time, the fresh water supply will continue to flow, the cleaning valve will be opened, and the water pressure in the cleaning chamber and the suction pipe will be greatly reduced. With the pressure difference, a suction force occurs between the suction pipe and the cleaning chamber through the suction nozzle, forming a suction process. Together, the electric motor drives the suction pipe to make a spiral movement in the axial direction. The combination of the axial movement and rotary movement of the suction cleaner thoroughly cleans the entire surface of the filter screen. The entire scouring process takes only tens of seconds. The blowdown valve is closed at the end of the wash. The filter begins in preparation for the next flush cycle.

The water to be treated enters the body from the water inlet, and impurities in the water are deposited on the stainless steel screen, thereby causing a pressure difference.
After the equipment is installed, the technicians debug and set the filtering time and the cleaning conversion time. The water to be treated enters the body from the water inlet. The filter starts to work normally. When the preset cleaning time is reached, the electric control hydraulic control valve The driving motor signal triggers the following actions: The motor drives the brush to rotate, cleans the filter element, and controls the valve to open for drainage. The entire cleaning process only needs to continue for dozens of seconds. When the cleaning is completed, the control valve is closed and the motor stops rotating The system recovers to its initial state and begins to enter the next filtration process.
Working principle of circulating water filter (3)
Water enters the filter from the water inlet. First, the coarse filter element is used to filter out large particles of impurities, and then it reaches the fine filter. After filtering the fine particles through the fine filter, the clear water is discharged from the water outlet. During the filtration process, the inner layer of the fine filter gradually accumulates impurities, and a pressure difference is formed between the inner and outer sides. When this pressure difference reaches the preset value, the active cleaning process will begin: the blowdown valve is opened, the hydraulic motor room and hydraulic cylinder of the main assembly release pressure and discharge water; the pressure in the hydraulic motor room and the suction pipe is greatly reduced. For the negative pressure effect, the dirt on the inner wall of the fine filter is drawn through the suction nozzle, flows into the hydraulic motor chamber from the hydraulic motor, and is discharged by the drain valve, forming a sewage suction process. When the water flows through the hydraulic motor, the sewage suction pipe is driven to rotate, and the sewage pipe is driven by the hydraulic cylinder piston to move the sewage pipe axially. The combination of the axial movement and the rotation movement of the sewage suction device assembly thoroughly cleans the inner surface of the filter. The entire cleaning process will continue for tens of seconds. The drain valve is closed at the end of the cleaning. The added water pressure will bring the hydraulic cylinder piston back to its initial position, and the filter will start to prepare for the next flush cycle. During the cleaning process, the normal filtering work of the filter is uninterrupted.
