WFF-125-1 Generator stator cooling water filter element is installed in the matching filter MSL-125 of the turbine generator 600MW unit. It is the filter element of the stator cooling water system in the generator hydrogen oil-water system. It’s used to remove more than 5% of the water carried by the treated make-up water or constant cooling water when passing through the filter through the microfiltration filtration device μ M impurities. Micron precision remains unchanged for a long time, because the wound matrix always maintains the same size, which can only be adjusted by changing the quality and physical characteristics of the filter medium inserted. The filter element fully meets the requirements of fiber length processing filter medium, so that the medium fiber can span at least three frames near the outer diameter, and the closer it is to the inner diameter, the more. Combined with the control of filter medium quality and bridging, all filter elements have accurate, consistent and stable precision.
