I would like to ask, constant pressure pump set pressure 20Mpa, the actual load is 15Mpa, then the constant pressure pump outlet pressure? If it is 20Mpa, then where is the loss of 5Mpa? If 15Mpa, the constant pressure pump 20Mpa how to understand? In addition, the constant pressure pump pressure is defined when the flow began to reduce the point, or a sharp drop in flow after the point?
Constant pressure pump is pressure maintained at the set pressure, flow control valve according to the order, there is pressure to set, after the pump displacement is reduced, as for how to reduce emissions, to see how much you need to flow.
The pressure loss is borne by the valve. Constant pressure pumps generally do not export direct load, unless you need this load response is very fast, then the maximum displacement of the pump work, so as to ensure the rapid response of the load.
15MPa. 20MPa means that if you enter the 20MPa, the variable mechanism will work, and the flow at this time automatically matches the load. 20MPa used to supply the fuel by maximum displacement.
