Working principle of filter

Filter for treatment of water by water entry into the body, the impurities in the water deposit in stainless steel mesh, the resulting differential pressure.Through differential pressure switch monitor changes into the filter outlet pressure difference, when the differential pressure to set data, control device for hydraulic control valves, motor drive signal, caused by the following action: motor driving brush rotation, the filter cleaning, emission control valve to open at the same time, the whole cleaning process for dozens of seconds, when the end of the cleaning, close the valve, the motor stop running, system back to its initial state, began to filter into the next process.
After the equipment installation, the technical personnel to debug,  the technician to set time filtering and cleaning conversion time, to be processed in the water by water entry into the body, filter began to work, when reaches the preset cleaning time, electric control device for hydraulic control valves, motor drive signal, caused by the following action: motor driving brush rotation, the filter cleaning, emission control valve to open at the same time, the whole cleaning process for dozens of seconds, when the end of the cleaning, close the valve, the motor stop running, the system back to its initial state, began to filter into the next process.
Inside the shell of the filter is mainly composed of coarse mesh and fine mesh, soak pipe, stainless steel brush or stainless steel suction nozzle, sealing ring, anticorrosive coating, and other components of the axis of rotation.
