A shock pressure test system

Abstract

The invention discloses an impact pressure test system, which includes a high-pressure open control subsystem and a servo control subsystem; the high-pressure open control subsystem includes a liquid replenishment pump group I, a high-pressure pump, an electromagnetic proportional overflow valve I, and an air-controlled ball valve I , Air-operated ball valve II; the high-pressure pump draws oil from the first oil tank, fills it with the test piece to be emptied, and then adjusts the electrical signal of the electromagnetic proportional relief valve according to the pressure required for the test and the real-time data feedback from the pressure sensor To achieve the desired pressure waveform. The servo control subsystem includes the second oil tank, the main pump group, the liquid replenishment pump group II, the plate check valve, the pipe check valve, the electromagnetic proportional overflow valve II, the accumulator II, the servo valve, and the booster cylinder; The main pump unit is turned on, the system pressure is set by adjusting the electromagnetic proportional relief valve II, and then the booster cylinder is controlled by the servo valve to become an alternating power source, so that the required high-frequency pulse test pressure curve can be obtained at the end of the test piece .

Description

technical field [0001] The invention belongs to the technical field of pressure test devices, and in particular relates to an impact pressure test system. Background technique [0002] For some products, such as the aviation fuel system, after the production design, the impact pressure test is carried out. Generally, the product shell and the shell assembly are tested through the ordinary pulse test bench. None of them can meet the test requirements of the product, and the impact pressure trapezoidal wave curve cannot be realized in the case of leakage, which makes the target test unstable and cannot be tested according to the actual working conditions, resulting in inaccurate test results, and the tests of different working conditions It cannot be done on one device. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an impact pressure test system. [0004] The present invention is achieve...
