What is the purpose of this pipeline in front of the centrifugal pump? It says on the drawing that it’s a pressure balance pipeline. Could anyone who knows explain this? If it’s a pressure balance pipeline, how is balance achieved?

What is the purpose of this pipeline in front of the centrifugal pump? The diagram shows it as a pressure balance pipeline. Could someone who knows this explain it? If it’s a pressure balance pipeline, how is balance achieved?
I’m not sure what this process is; I guess it might be a steam drum. This connecting pipe seems to have no connection to the pump – it’s probably a pipe used to maintain the balance of gas, liquid, and slurry levels inside the steam drum. A tube for balancing liquid level and air pressure. I’m not sure if this understanding is correct. I remember there was such a circuit in the converter steam vessel of the steel plant. For reference.
The condensate pump of a condensing steam turbine is equipped with this line, which is used for venting air before starting the pump after maintenance.
Gentlemen, this is the outlet of the condensate transfer pump, leading to the carbon scrubbing tower for vaporization
A negative pressure system, right? It is useful when using a pipeline filling pump to remove air from the pump inlet pipeline and the pump itself; generally, the piping should be connected from the horizontal pipeline at the pump inlet. For reference only
It could be: a condensate vaporization equilibrium pressure tube, to prevent vaporization due to a drop in pressure at the inlet of the transfer pump.
Vacuum exhaust pipeline to prevent pump cavitation
It is used to fill the pipeline before the pump before startup, and should be turned off during startup.
