The water filter element SL-12/50 use in generator stator cooling water system. The stator coil cooling water system forms an independent closed self-circulation system. The water pump absorbs water from the water tank, boosts the pressure and sends it to the water cooler for cooling. After filtering out mechanical impurities through the water filter, it enters the generator stator coil, and the water flows back to the water tank for continuous circulation. The system is equipped with two parallel filters, which are arranged at the downstream of the cooler. During normal operation, one is in operation and the other is standby, mainly to prevent solid impurities from blocking the hollow conductor of the stator coil. The effect of water cooling is 50 times that of air cooling. In order to better cool the generator, it is necessary to select a suitable filter element, which not only effectively prevents pollutants, but also has a good cooling effect.
SL-12/50 filter element is suitable for 300MW, 330MW, 350MW generator stator cooling system.
Generally, generator stator cooling water filter element SL-12/50, the unit is equipped with 12 pieces/set, 24 pieces/set, and 36 pieces/set.
According to different unit configuration periods and unit sizes, the size of the water filter element is different.
