Abstract

The present invention provides a pipeline reliability testing device which comprises a drying module, a temperature control module, a testing module and a pulse pressure generator installed in order. The gas outlet end of the drying module is divided into two paths which are respectively connected with the heating gas path and the cooling gas path of the temperature control module, the testing module is at least one testing gas paths which are installed in parallel, the hand of the robot of a vibration device stretches into a test box, a testboard is installed at the end portion of the handle, and the handle drives the testboard and pipeline samples to realize three-axial vibration. The vibration device is simple in structure so as to simulate different temperatures, pulse pressures and vibration conditions of an engine in a working process and test the reliability of a turbocharging tube with no need for configuration of a special engine, the test structure is simple, and the cost is saved. The vibration detection device is connected with the testboard, the amplitudes and frequencies of the three-axial directions of the vibration block are the completely same as these of the handle, and displacement sensors of three directions are employed to accurately detect the amplitudes and the frequencies of three-axial direction vibration so as to ensure that the real vibration effect accords with the test requirements.

Description

technical field

[0001] The invention relates to the field of test equipment, in particular to a test device for simulating the actual working conditions of an automobile turbocharger tube and detecting the reliability of the pipeline. Background technique

[0002] With the continuous improvement of energy consumption and emission indicators in the automotive industry, turbocharging technology has gradually become one of the main development directions in the field of automotive engines. Turbocharging technology refers to the high-temperature and high-pressure exhaust gas discharged from the exhaust pipe of the engine. The exhaust gas is transmitted to the turbine chamber through the turbocharger pipe, driving the turbine in the turbine chamber to rotate, and the turbine drives the coaxial impeller to rotate. The impeller compresses the air to increase the gas density, so that the unit The quality of the air in the volume is greatly increased, and the compressed air enters th...

Embodiment Construction

[0023] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0024] Such as figure 1 As shown, the pipeline reliability testing device of the present invention includes a drying module, a temperature control module, a testing module and a pulse pressure generator 31 installed in sequence. The air compressor 1 and the first air storage tank 2 are installed in sequence at the air inlet of the drying module, and the air outlet of the first air storage tank 2 passes through the coarse-effect filter 3, the freeze dryer 4, the medium-efficiency filter 5 and the fine-effect filter in sequence. Filter 6, filtered clean gas enters the second gas storage tank 7. The gas outlet end of the second gas storage tank 7 is divided into two paths after passing through the valve 8, and one path is connected to the heating gas path of the temperature control module. and the temperature sensor 14; the other is connect...
