Axial Thrust In Boiler Feed Pump Related Information

Axial thrust by CENTRIFUGALPUMP.COM

2019-8-15 · The axial thrust load is carried by the pump's thrust bearing which is usually of the anti-friction (ball bearing) type. The thrust bearing should be capable of carrying reversing thrust, if applicable. In a single stage unit the thrust imbalance is usually small enough that the thrust bearing is more than sufficient to handle the thrust load.

What are BFP ( Boiler Feed Pump ) - Parts & Working

Role of Boiler Feed Pump in Boiler Feed System Working Principle of a Boiler Feed Pump. The work of a boiler feed pump is to discharge the condensate boiler feed water from hotwell to the boiler drum. With the rotation of shaft and impeller the hot feed water is thrown outwards radially across the walls of the pump; along the path of the flow.

Why the boiler feed water pumps requires minimum

2011-11-3 · If the axial pressure is not balanced then the shaft will shift axially and cause damage to the pump. Since boiler feed pumps are subject to changes in flow rate and can on occasion have their flow either interrupted or reduced to a very low rate by the boiler level control system there is a need to maintain the minimum flow.
