Feed water pump
Thread Content
Dear experts, is the flow meter for the boiler feed water pump installed at the inlet or the outlet of the feed water pump?
There is a pressure drop at the outlet and inlet, which affects the pump’s flow rate.
It’s usually at the export point. Moreover, a centrifugal pump can only regulate the flow rate at its outlet.
Outlet: the flow control orifice plate is located outside the outlet valve
May I ask, why is the flow orifice plate installed on the inlet pipe when explaining how to use the minimum flow valve?
Throttle orifice plate loading outlet. The minimum flow valve is installed on the recirculation pipeline. Two things
It is generally installed at the pump’s outlet; the flow rate allows one to determine the pump’s efficiency, and a interlock device must also be provided
Either one will do; it is mainly used for calculating flow rate. The outlet pressure is high, resulting in relatively high costs. When designing the inlet, it is necessary to take into account the pump’s net positive suction head.
