Embodiment Construction

[0032] The technical solution in the embodiment will be specifically, clearly and completely described below in conjunction with the drawings in the embodiment.

[0033] see Figure 1 to Figure 3 As shown, the interactive pressure testing system of the ultra-thin film of the present embodiment is used to test the fatigue life of the ultra-thin film, and includes two support bodies 10, and the first support bodies 10 connected to each other are respectively arranged on the support body 10. Bellows flange 21 and second bellows flange 22 (also called left bellows flange and right bellows flange), the outer end of the first bellows flange 21 is connected with a first sensor 31, The outer end of the second bellows flange 22 is connected with a second sensor 32 , and an ultra-thin film 5 to be tested is arranged inside between the first bellows flange 21 and the second bellows flange 22 .

[0034] The test device also includes a micro-pressure control unit (not shown in the figure)...

Abstract

The invention discloses an interactive pressure test system for ultra-thin film sheets, which comprises first and second membrane box flanges that cooperate with each other, and the first and second membrane box flanges are respectively connected with first and second membrane box flanges. The sensor, during the test, the ultra-thin film to be tested is fixed between the first and second bellows flanges, and the ultra-thin film to be tested is also connected to the first and second bellows respectively. The flanges are sealed and matched to form the first and second air chambers. The first and second air chambers are communicated with the air source through the micro-air pressure control unit. The first and second sensors are respectively matched with the first and second air chambers. . The invention also discloses an interactive pressure test method for the ultra-thin film sheet. With the device and method of the present invention, other damage modes other than performance damage will not be caused to the product during pressurization, the problem of pulsation control accuracy under micro-air pressure is solved, and at the same time, it is fully simulated and equivalent to the normal operation of the ultra-thin film sheet. The actual industrial control can fully reflect the performance of the diaphragm product, and the application prospect is good.

Description

technical field [0001] The invention relates to an interactive pressurization test system, in particular to a test device for alternately pressurizing an ultra-thin membrane under micro-pressure to verify the fatigue life of the ultra-thin membrane, and belongs to the technical field of membrane testing . Background technique [0002] The existing pressure test technology for ultra-thin films is not perfect. Existing test devices generally cause performance damage or other damage to the product during the pressurization test. Moreover, the existing test device cannot solve the problem of pulsation control accuracy under micro-pressure, and at the same time, it cannot simulate the actual industrial control of the ultra-thin film when it is working normally, so it cannot fully reflect the performance of the diaphragm product, which affects the production and product quality of the enterprise. Detection has had a big impact. [0003] Therefore, it is necessary to provide an ...
