This paper deals with the pressure ripple of the double vane pump using modern spectrum analysis—maximum entropy spectral estimation and indicates the causes of pressure ripple.
This paper calculates, analyses and determines the pressure point of maximum of ouput power and saving-energy efficiency of differential pressure and Limited pressure variable displacement pump.
