With 2 chilled water pumps connected in parallel, why does the current of the other pump increase when the outlet of one pump is reduced?

With 2 chillers connected in parallel, why does the current of the other unit increase when the outlet of one unit is reduced? ?
The flow rate of the other unit has increased, so naturally the current will rise. Stop asking why the flow rate has increased~
Maybe you have set the output amount to be fixed
When the current increases, the flow rate increases, the power increases, and the volume of flow entering increases; it’s only logical that the inlet pressure will increase as well. But what exactly does inlet pressure mean? If that outlet is closed, the inlet pressure also decreases. Is the pressure too high on the other imported unit? ? ? ?
When one of the parallel pumps is shut down, the flow rate in the pipeline system downstream of the pump’s outlet decreases, and the pressure drop reduces, which leads to a decrease in the pressure at the pump’s outlet. The increase in flow rate of the remaining pump is influenced by the characteristics of the pipeline system at the pump’s outlet, and it has nothing to do with the inlet pressure.
As head decreases, flow rate increases, power increases, and current increases
