Final answer:
The start-up procedure for a centrifugal feed water pump involves inspecting, priming, and gradually increasing the speed of the pump. The shut-down procedure involves draining the water, performing maintenance, and inspecting the pump.
Step-by-step explanation:
A centrifugal feed water pump is a type of pump used in power plants and other industrial applications to deliver feedwater to a boiler. The start-up procedure for a centrifugal feed water pump involves several key steps. Firstly, the pump is inspected for any damage or blockages. Then, the pump is primed by filling it with water to remove any air pockets. Finally, the pump is turned on at a low speed and gradually increased to its operating speed.
The shut-down procedure for a centrifugal feed water pump is just as important. The pump is first slowed down to a low speed to allow the water to drain from the system. Then, the pump is turned off, and the remaining water is drained from the pump and associated piping. The pump is then inspected and any necessary maintenance or repairs are performed.
