Then the influence of flow, pipe length, setting pressure of relief valve and stiffness coefficient of main valve spring on the water hammer peak pressure at the instant of fuel pistol closing was studied according to the detected pressure signals. Finally, the relatively accurate gas-liquid separation value and critical cavitation pressure value of the system was obtained by frequency analysis and wavelet analysis.
