Why can’t the check valve located between the inlet and outlet of the centrifugal pump be opened when it is used for feeding? ——This is to ensure the maximum material feeding flow and speed up the material feeding process. What is the purpose of circulating after unloading is complete? ——Does the pump run continuously? To prevent the pump from getting stuck.
Circulation is used to prevent pump damage from high pressure; there’s no need for circulation if the pressure isn’t high
Some are also used to prevent materials from condensing inside the pipes
