It is well known that the test state of the gas cylinder internal pressure test method is more in line with the measurement of the residual deformation rate of the cylinder volume than the test model of the cylinder water pressure. For the measurement principle, the internal test method is more capable. It reflects the real situation under the conditions of product hydraulic pressure test, which is more scientific and reasonable.
So, what are the advantages of the gas cylinder internal pressure measurement method? Today, Xiaobian will bring you to study.
2 The gas cylinder external pressure test method is simple and the equipment value is relatively low, which meets the requirements of mass production.
2 Through theoretical analysis, the test state and test model of the internal test method are more in line with the measurement requirements of the residual deformation rate of the cylinder volume, which can reflect the real situation of the product test, and is more scientific and reasonable. Even in the case of mass production with bubbles, the internal measurement method enlarges the residual deformation rate of the product, and does not let the product whose residual deformation rate is originally out of tolerance. Therefore, the requirements are stricter and the safety performance is higher.
2 Measuring residual deformation rate in a cylinder water pressure test is only one part of it. Whether it is the US DOT specification, ISO11439, BS 5045 and other foreign standards, or China's GB 5099, GB 17258 and other gas cylinder standards, it is clearly required that no leakage or leakage of any part of the cylinder during the water pressure process, the surface of the bottle is not Obvious deformation, no abnormal sound, any situation. Since the gas cylinder internal pressure measurement method has no line of sight obstacles, these defects can be visually reflected and meet the standard requirements.
