ABSTRACT:
A device and method are disclosed for monitoring the cavitation parameters of a positive displacement fuel pump. A flow proportional to the flow of the pump is branched off a supply line to a cavitation venturi at a pressure lower than the supply pressure, while regulating the proportional flow and the venturi so that the latter attains its cavitation range prior to the cavitation of the positive displacement pump. In this range, the pressure at the inlet of the venturi is equal to the critical feeder pressure of the volumetric pump. The difference between the supply pressure of the positive displacement pump and the pressure of the inlet of the venturi is detected and a control signal generated to activate an alarm or increase the pressure of the supply fluid.
