Hydraulic pressure-resistant test method and hydraulic pressure-resistant test device

Abstract

The invention relates to a hydraulic pressure-resistant test method and a hydraulic pressure-resistant test device. The hydraulic pressure-resistant test method comprises the following steps that according to first preset liquid injection flow, injecting liquid into a container; when liquid injection amount reaches preset liquid injection amount, according to second preset liquid injection flow, injecting liquid into the container; when the liquid injection amount reaches preset test liquid injection amount, stopping injecting liquid into the container, and monitoring inner hydraulic change or outer hydraulic change of the container; obtaining inner hydraulic change or outer hydraulic change information of the container for statistics, so as to obtain hydraulic pressure-resistant test data. According to the hydraulic pressure-resistant test method, the liquid injection flow is quickened in an earlier stage of the test, so the liquid injection time is shortened, and the liquid injection flow is delayed in a later stage to ensure the accuracy of the liquid injection amount, so that not only can test efficiency be improved, but also the test accuracy can be improved. The hydraulic pressure-resistant test device is reliable in structure, can intelligently control the liquid injection flow injected into the container, and can improve the test efficiency, and also can improve the test accuracy, reduce labor intensity and reduce the test cost.

Description

technical field [0001] The invention relates to the technical field of hydraulic pressure resistance test, in particular to a hydraulic pressure resistance test method and a device thereof. Background technique [0002] The hydraulic pressure resistance test is a test item involved in the manufacture, inspection and acceptance of the container. The traditional test method is to subject the liquid (water or other specified liquid) to the hydraulic pressure resistance test. Filling the liquid, the traditional method of filling the liquid is to use the same flow rate, manually staring at the pressure gauge of the container to see if it is full, a lot of time is wasted for a large container; after that, slowly increase the design pressure, and rise to the test without leakage The pressure should be kept for no less than 30 minutes, and the inspection should be carried out after a sufficient time for the pressure, and the pressure should remain unchanged during the inspection.

[0002] The hydraulic pressure resistance test is a test item involved in the manufacture, inspection and acceptance of the container. The traditional test method is to conduct a hydraulic pressure resistance test on the liquid (water or other specified liquids). Filling the liquid, the traditional method of filling the liquid is to use the same flow rate, manually staring at the pressure gauge of the container to see if it is full, a lot of time is wasted for a large container; after that, slowly increase the design pressure, and rise to the test without leakage Pressure, keep the pressure for no less than 30 minutes, check after enough time to keep the pressure, the pressure should remain unchanged during the inspection

The traditional test method has the following disadvantages: First, it needs to control the pressure manually, which requires high professional skills of the operator; second, it takes a long time to maintain the pressure, which is laborious and inefficient.
