HYDROMECHANICAL PRESSURE COMPENSATION CONTROL OF A VARIABLE DISPLACEMENT PUMP IN A CENTRIFUGAL PUMPING AND METERING SYSTEM AND ASSOCIATED METHOD |
摘要 |
A pump assembly includes a pump unit having a centrifugal pump and a variable pump supplying pressurized flow. A fuel control assembly receives flow from the pump unit and includes at least one metering valve and at least one throttling valve. A control for the variable pump receives first and second pressure signals indicative of a pressure differential across the throttling valve, or across the metering valve/throttling valve combination, for altering operation of the variable pump in response to the pressure differential. |

1. A pump assembly comprising:
a pump unit including a centrifugal pump and a variable pump supplying pressurized flow; a fuel control assembly receiving flow from the pump unit, the fuel control assembly including at least one metering valve and at least one throttling valve; and a control for the variable pump receiving first and second signals indicative of a pressure differential across at least the throttling valve, or across the metering valve/throttling valve combination, for altering operation of the variable pump in response to the pressure differential. |
