Multifunctional adjustable pressure test system

Abstract

The invention discloses a multifunctional adjustable pressure test system, which includes a high-pressure open control subsystem and a servo control subsystem; Valve Ⅰ; the high-pressure pump draws oil from the high-temperature tank, fills it with the test piece and empties it, 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 required The pressure waveform; a heating system is installed in the high-temperature tank to meet the high-temperature and high-pressure test requirements for test pieces. The servo control subsystem includes the system oil tank, the main pump group, the liquid replenishment pump group II, the electromagnetic proportional overflow valve II, the accumulator II, the servo valve, and the booster cylinder; The system pressure is fixed, 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 a multifunctional adjustable 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. Both the aspect and the temperature cannot 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. The test pressure and temperature cannot be satisfied at the same time, and the tests under different working conditions cannot be completed on one device. Contents of the invention [0003] The purpose of the present invention is to overcom...
