Details
The DG type high-pressure boiler feed pump is a single-shell segmented multi-stage off-pump. The pump is double-supported. The inlet and outlet are vertically upward. The bearings are sliding bearings, lubricated with thin oil, and equipped with an oil-stripping ring. Axial force balance drum mechanism, residual axial force by a pair of angular contact ball bearings, shaft seals with soft packing seals, mechanical seals can also be used. It is used for boiler feed water in thermal power plants and can also be used for cleaning water pumps. The direction of rotation of the pump is clockwise rotation in the direction of power transmission.
