Jul 18, 2018 · The boiler feed pump function is to supply pressurized feed water to the boilers maintain the water inventory at various operating loads. Boiler feed water pumps are commonly centrifugal pumps. To ensure a high enough head and pressure, Boiler feed Pumps have been arranged in series (multistage pumps). A feedwater pump is most often driven by an electric motor for energy efficiency.
Aug 22, 2018 · Long-term neglect of the pump case and/or motor cover studs of a BWCP can cause them to corrode and seize. New pump case studs have a zinc phosphate coating to improve corrosion resistance and paint adhesion with a high temperature antifriction coating. If the pump case or motor case gasket leaked or the plant is subjected to flooding, the studs can corrode and bind in place.
Boiler Feed Water Pump Working Principle and Operation
A boiler feedwater pump is a specific type of pump used to pump feedwater into a steam boiler.The water may be freshly supplied or returning condensate produced as a result of the condensation of the steam produced by the boiler. These pumps are normally high pressure units that take suction from a condensate return system and can be of the centrifugal pump type or positive displacement type.
Dec 19, 2020 · The common faults of the circulating feed water pump for the boiler are: (1) The electric feed pump motor is overheated. (2) The feed water pump body is overheated. (3) The boiler feed water pump has insufficient flow. Analysis and elimination of motor overheating of circulating feed water pump for electric boiler: For feed water pump powered by electric motor, motor overheating is the most …
Jun 25, 2014 · Water will flow from the receiver tank into the boiler, and the boiler may flood. If you have a boiler-feed pump, the problem will be very noticeable. That's because a boiler-feed pump has an automatic water feeder in its receiver. The feeder gives the pump an endless supply of fresh water.
