Changzhou Long Ze Pipe Sales Co., Ltd. (Diaoya Wen 18731744075 0317-5128359) filters to be processed into the body of water from the inlet, the water of impurities deposited on the stainless steel filter, the resulting pressure differential. Monitoring of the pressure switch in and out of the outlet pressure changes when the pressure reaches the set value, the electrical controls for the hydraulic control valve, drive motor signals and trigger the following actions: motor driven brush rotation, cleaning the filter, while the control valve open sewage, the entire cleaning process takes tens of seconds, when the cleaning is finished, close the control valve, the motor stopped turning the system back to its initial state, began to enter a filtering process. Equipment installation technicians to debug, set the filtration time and cleaning conversion time to be processed into the body of water from the inlet, the filter work properly when reaches the preset cleaning time, the electrical controls for the hydraulic control valve , the motor drive signal, causing the following: motor driven brush rotation and cleaning filter, while the control valve to open sewage, the entire cleaning process takes tens of seconds, when the cleaning is finished, close the control valve, motor stops rotating the system back to its initial state, began to enter a filtering process. Filter inside the shell is mainly composed of coarse filter, fine filter, sewage suction pipe, stainless steel brushes or stainless steel nozzle, seals, anti-corrosion coating, the axis of rotation and so on.
