Screen Filter Filtration
Water enters the filter through the "Inlet" (1) and passes through the coarse screen (2) that functions as a "first stop" for rough particles. Water then reaches the fine screen (3), which further purifies the flow by separating smaller particles from the water. As more water flows through, impurities build up on the fine screen. As impurities
on the screen accumulate, a pressure imbalance is built up between the internal section of the fine screen (3) and its external section.
Screen Filter Cleaning Process
When the difference in pressure reaches the preset value on the differential pressure indicator, a series of events is triggered while the water continues to flow to the system units. The flushing valve (4) opens, and water flows outside. Pressure in the hydraulic flushing chamber (5) and the dirt collector (6) is signifigantly lowered resulting in a suction process via
the suction nozzles (7) to the dirt collector (6) and from there through the flushing valve (4) outside. The electric motor (8) simultaneously rotates teh dirt collector (6) and moves it along its axis. The combination of the linear movement and rotation effciently cleans the entir internal screen.
The flushing cycle continues as long as the pressure differnce between the inlet and outlet remains the same and according to signals from the controller. If the pressure difference remains unchanged for a fixed preset time, the emergency flushing valve (9) opens along with the norma flushing valve (4). The flushing cycle continues for the time that was
preset on the controller. The flushing valves (9) & (4) close when the pressure difference on the pressostat drops. The operation of the electric motor is stopped after the collector axis reaches the internal or external limit switches. The filter is now ready for the next cycle, with clean and filtered water flowing throught the "Outlet" (10).
