Problems solved by technology

[0004] (1) Low test efficiency
This detection method is usually operated by manual control, which is inefficient;
[0005] (2) This detection method cannot observe the change of vacuum degree during the test process, and cannot directly obtain the test results;
[0006] (3) This detection scheme has a relatively simple control form for the boost and price reduction of the vacuum container, and it is impossible to obtain accurate parameters

Abstract

The invention discloses a vacuum pressure relief and recovery fatigue test system, and the system comprises a test container; the test container is provided with an air inlet and an extraction opening, the air inlet and the extraction opening are respectively connected with a flow controller group and a vacuum pump group, the flow controller group is connected with a pressure regulating valve group, and the pressure regulating valve group is connected with a high-pressure air source. The production efficiency is improved. Compared with a traditional detection mode, the vacuum pressure relief and recompression fatigue test system has the advantages of being rapid and convenient to use, the high vacuum degree can be achieved, and the vacuum change speed can be controlled.

Description

Technical field[0001]The invention relates to the field of vacuum container detection, and in particular to a vacuum relief recompression fatigue test system.Background technique[0002]The fatigue test of a vacuum vessel is an important link in the production process and an important means of evaluating its performance. Among them, the choice of material and wall thickness during the design of the vacuum vessel has always been the key parameter in the actual production process. Since the vacuum container is in use, when the required vacuum is high, the tank body of the vacuum container is more prone to deformation. The long-term deformation of the vacuum container will greatly affect the strength of the tank material. The risk of tank rupture and leakage.[0003]Prior to the present invention, the fatigue test of the vacuum container usually only used a vacuum pump to evacuate the vacuum container. After reaching a certain degree of vacuum, the vacuum container was restored to normal p...
