The invention provides a pressure pulse testing
machine, and aims to solve the problem of inaccurate control of measuring parameters and waveforms due to
pressure difference existing among each pressurizing point in the conventional pressure pulse technology although air pressure serving as a constantly-existing
natural product can be used for effectively detecting a
pressure sensor. Technical key points of the invention are that an air storing cabinet comprises a primary pressure cavity and a secondary pressure cavity; the primary pressure cavity is connected with an
air pump; the upper part of the secondary pressure cavity is provided with an elastic connector, an air inlet
servo valve and a standard pressure cavity in sequence; the side wall of the standard pressure cavity is provided with an exhaust
electromagnetic valve group and an adjusting
electromagnetic valve; pressurizing holes are uniformly distributed in the upper surface of the standard pressure cavity; a
pressure sensor of a standard sensor with a waveform feedback measuring function is arranged in at least one of the pressurizing holes. The pressure pulse testing
machine has the positive effects that fatigue test can be performed on a tested object under the condition that the tested object is not damaged. The pressure pulse testing
machine further has the characteristics of high control degree, low cost, stability, reliability, high practicability and the like.
