Structure characteristics :
Boiler feed pump for the axial ring segment superposition of multi-stage pump, impeller is a single closed structure, two supports for roller bearing, constant level lubrication, axial load by the balance disc is arranged on the outlet side of the pump for thrust balance.
1.The pump body is a cylinder type axial stacking structure, and a plurality of M50 straight through bolts are tightened, and each grade separator is sealed with a O shaped rubber ring.
2.The inlet and outlet flange connecting pipe and the pump body are welded connection.
3.The partition and the impeller interval in the spindle assembly, namely a clapboard and an impeller, then hold a clapboard and an impeller, sealed by an end cover export final partition, bolt location.
4.Two of the pump end seal with self-lubricating stuffing.
5.Lubrication pump, oil cup at both ends by constant level lubrication, with the temperature of the circulating water cooling bearing box.
