The filter is indispensable as a conveying medium piping means, usually installed in the valve, the pressure relief valve, the inlet end of the fixed water level valves or other equipment used to remove impurities in the medium, to protect the valves and equipment normally to use. When the fluid enters the set certain specifications filter cartridge, the impurity is the barrier, while the clean filtrate from the filter outlet, and when cleaning is required, as long as the removable cartridge removed remounted after processing i.e. may, therefore, extremely easy to use and maintenance.bag filter Filters inside the casing includes a coarse filter, fine filter, sewage suction pipe, stainless steel brush or stainless steel nozzle, seals, anti-corrosion coating, rotating shaft. Filters water to be treated from the inlet into the body, and the impurities in the water is deposited on a stainless steel strainer, thereby generating a pressure differential. Inlet and outlet pressure changes when the differential pressure reaches the set value, the electrical controls for the hydraulic control valve, drive motor signals, lead to the following actions: motor driven brush rotation and cleaning the filter, the control valve is opened at the same time by the differential pressure switch monitoring sewage, the entire cleaning process only for tens of seconds, and to close the control valve when the cleaning is finished, the motor stops rotating, and restore the system to its initial state, to start into the next filter step. Equipment installation, commissioning, by the technical staff set the filtering and cleaning the conversion time, the water to be treated into the body of the inlet filter begins normal operation, when the the default cleaning time is reached, hydraulic control valves, electrical controls drive motor signals to trigger the following actions: motor driven brush rotation, cleaning the filter, the control valve is opened for sewage entire cleaning process takes only lasts tens of seconds, when the cleaning is finished, close the control valve, the motor stops rotating. restore the system to its initial state, and started to enter the next filter step.
