What is the difference between a flow restriction orifice plate and a pressure reduction orifice plate?
Thread Content
Does current limiting necessarily require pressure reduction? It seems that flow restriction orifice plates and pressure reduction orifice plates are the same thing; there’s no difference between them
It should be the same thing. They serve the same purpose: current limiting and pressure reduction.
In my opinion, throttling will definitely lead to voltage reduction, but voltage reduction does not necessarily mean throttling.
Firstly, the flow-limiting orifice plate functions both to limit flow and to regulate pressure. There is a proportional relationship between the flow rate, the pressures before and after the plate, and the orifice diameter; by knowing two of these values, it is possible to determine the third. Therefore, generally, by knowing the flow rate and the pressures before and after the plate, it is possible to determine the orifice diameter.
