Description
HOW IT WORKS
Water enters the filter through the inlet (IN), it goes through the filtering cylinder (1) from inside out, which retains the suspended filters to be filtered; it retains all suspended solids with size larger or equal to the filtration degree installed. Filtered water leaves through the master valve (OUT).
REGENERATION
The continuous settling of suspended solids obstructs the passage of water which results in a pressure difference (∆P). At a preset value of ∆P (range 0.3 ÷ 1 Bar) an automatic cycle will start to clean the filter cylinder (1). This operation starts with a signal that closes the outlet valve, (2) which clears the ∆P, and opens the discharge valve (3). At the same time the electric motor (4) rotates the brushes (5) in the filtering cylinder to clear away the contaminant that is ejected through the discharge valve (3). The cleaning cycle lasts approximately 20 seconds.
CONTROL
A switchboard controls the washing phases. The signal that starts the cleaning cycle is given by a differential pressure switch or by time. The switchboard gives an “alarm” signal in case of problems in the washing system. These signals can be sent to a pre-existing control centre. The washing phase can also be controlled manually. The solenoid controlling the valve is pneumatic.
