High temperature boiler feed water pump
The DG120-50X5 boiler feed water pump is a 5 stages multistage water pump. Both of the inlet and outlet are vertical. This boiler feed water pump are made of cast steel with mechanical seal. The pump's lubrication is oil with rolling bearing.
The rotor part of the boiler feed water pump is mainly composed of the shaft and the impeller, shaft sleeve and balance plate installed on the shaft, and the number of the impeller is determined according to the series of the pump. The shaft parts are fastened with a flat bond and a shaft nut to combine with the shaft. The whole rotor is supported by a rolling bearing or a sliding bearing at both ends. Bearing is determined by different types, and does not bear axial force. Its axial force is allowed to move axially in the pump shell by balancing the balance of the disc and balancing the A pump. The centripetal ball bearings are not used.
