Drum-like rotating filter net

which is the main filter device of nuclear power plant circular water system is driven by electromotor through gear wheels

the smaller one linked the bigger one with the electromotor.Sundries in water are filtrated by the filter board in drum-like rotating filter net to insure the pump and heat transformation device following it working order.The reasons of hardly abrasion between gear wheels is analyzed

and the driven manner between gears is improved.Result shows that the improved driven gears can totally satisfy working and repair cycle requirement.
