Embodiment 1

[0034] Embodiment 1: as figure 1 , 9 As shown, the test device for the working pressure test of the thin hydraulic rubber capsule includes a pressure box 1, a top cover splint 2, a base splint 3, an auxiliary device 8 and an automatic pressure calibration device;

[0035] Such as figure 2 , 4 As shown, the pressure box 1 is placed between the base splint 3 and the top cover splint 2, and the bolt fastener 4 passes through the top cover splint 2 and passes through the bolt hole 7 corresponding to the base splint 3 to connect and lock the pressure box 1 ;

[0036] Such as Figure 6 , 7 As shown, the bottom center of the top cover splint 2 is provided with a limit boss 21, the outer diameter of the limit boss 21 is equal to the open inner diameter of the pressure box 1, and the top center of the base splint 3 is provided with a limit recess. groove 31, the inner diameter of the limiting groove 31 is equal to the outer diameter of the bottom of the pressure box 1;

[0037]...

Embodiment 2

[0048] Embodiment 2: The difference from Embodiment 1 is that Embodiment 2 also includes an automatic pressure calibration device, which is connected to a pressure gauge externally connected to the pressure test hole 5 . The automatic pressure calibration device is also connected with a pressure generator and a pressure transmitter. The pressure generator provides and outputs a predetermined pressure for parallel calibration pressure, and the automatic pressure calibration device outputs 22-25mA / 6- to the pressure transmitter. With a 10V drive signal, the pressure transmitter outputs the measured value of the predetermined pressure input from the pressure generator to the 22-25mA DC current superimposed on the current and return flow, and then sends it to the automatic pressure calibration device.

Abstract

The invention provides a testing device for working pressure inspection of a thin hydraulic rubber capsule and a test method thereof. The test device for working pressure inspection of the thin hydraulic rubber capsule includes a pressure bearing box, a top cover clamping plate, a base clamping plate and an auxiliary device. The pressure bearing box is placed in a center position between the top cover clamping plate and the base clamping plate through the auxiliary device, and is fastened and pressed by bolt fasteners passing through the corresponding bolt holes of the upper and lower clampingplates. The top cover clamping plate is provided with a pressure test hole and a pressure-filling hole, the pressure test hole is connected with the pressure meter, and the pressure-filling hole is externally connected with a hydraulic pump. The invention can carry out a pressure-filling test on the thin hydraulic rubber capsule, so as to test whether the capsule can reach a designed working pressure and keep the working state stable; and meanwhile, the invention can measure the maximum working pressure of the capsule, and check the tightness of the contact joints of each component.

Description

technical field [0001] The invention relates to the technical field of working pressure testing of hydraulic rubber capsules, in particular to a testing device and a testing method for testing the working pressure of thin hydraulic rubber capsules. Background technique [0002] Thin rubber capsules are non-standard parts. At present, there are no relevant regulations in China to stipulate their standard specifications and related parameters. A large number of scientific research and industrial practice have proved that among all process parameters, the working pressure index of rubber capsule has the greatest impact on product quality, and it is a comprehensive index of product quality. Therefore, after the production and processing of the thin rubber capsule, its related performance needs to be tested to check whether its various indicators meet the design requirements. However, there is no design work pressure test and sealing quality inspection of the thin rubber capsule ...
