The present invention discloses a thin film cyclic inflation and deflation fatigue detection device and method. The thin film cyclic inflation and deflation fatigue detection device comprises an inflation pipeline and a deflation pipeline which are communicated with a to-be-detected thin film member, the inflation pipeline is orderly equipped with an overflowing valve and an inflation solenoid valve, and the deflation pipeline is equipped with a deflation solenoid valve. The thin film cyclic inflation and deflation fatigue detection device also comprises a pressure electric controller which isconnected with the inflation solenoid valve and the deflation solenoid valve separately and electrically, and the pressure electric controller is used to control the inflation solenoid valve to turnon the inflation pipeline and transmit the compressed air of a set gas pressure outputted by the overflowing valve to a thin film of the thin film member to inflate the thin film with the constant pressure, and is also used to control the deflation solenoid valve to turn on the deflation pipeline and deflate the thin film after the constant pressure inflation. The thin film cyclic inflation and deflation fatigue detection device and the thin film cyclic inflation and deflation fatigue detection method provided by the present invention are high in automation degree, test efficiency and detection accuracy.
Description
technical field [0001] The invention relates to the field of detection of fatigue and service life of thin film parts, in particular to a device and method for detecting fatigue of thin film cycle inflation and deflation. Background technique [0002] The film in the film part is a sensitive key part of the whole film part. In a specific working environment, it is a parameter of great significance to the fatigue and service life of the entire membrane part, and it is related to the service life and maintenance cycle of the entire membrane part. Therefore, it is of great significance to develop a detection device for testing the fatigue and service life of the film. [0003] The fatigue and service life of the film in the film part are related to the maintenance cycle and maintenance cost of the whole film part. The film is repeatedly inflated and deflated to test the fatigue. The frequent action of each test is repetitive labor, and the time of each inflated and deflated m...
