Problems solved by technology

Although research institutions at home and abroad have carried out experimental research on the performance testing of non-metallic sealing materials and seals in high-pressure hydrogen environments, the range of test pressure and temperature is limited, which is lower than the actual application conditions; the device has a single function and cannot realize various types of tests. ; The test chamber is relatively large and the test efficiency is low

Abstract

The invention relates to a manufacturing and detecting technology of hydrogen storage and transportation equipment, and aims to provide a method for testing the performance of a non-metal sealing element in a high-pressure hydrogen environment. The test method comprises the following steps: forming a test cavity by a base and a gland, wherein an O-shaped ring sample clamping frame, a reducer pipe and a check ring are arranged in the test cavity; a tested O-shaped ring sample is embedded in grooves in the side edge and the upper surface of the O-shaped ring sample clamping frame respectively, and a static load exposure test, a circulating pressure fatigue test and a sealing performance test are carried out. The test cavity is small in size and low in gas consumption; the test condition can meet the actual service condition of the non-metal rubber sealing element; sample specification parameters can be expanded only by changing the size of the internal sample holder, the safety of the device is guaranteed, the test cost is reduced, the test efficiency is improved, and the problem that an existing nonmetal sealing material performance testing device is single in function is solved.

Description

technical field [0001] The invention relates to the manufacturing and testing technology of hydrogen storage and transportation equipment, in particular to a method for testing the performance of non-metallic seals in a high-pressure hydrogen environment. Background technique [0002] With the increasingly prominent problems of environmental pollution and energy shortage, it is very important to optimize the energy structure and ensure energy security. As an important secondary energy in the new century, hydrogen energy has the advantages of diverse sources, clean and efficient, storage and regeneration, and is one of the important energy sources to promote the industrial development of various countries. [0003] Non-metallic seals are widely used in various links of the hydrogen energy industry chain, such as hydrogen storage containers, hydrogen compressors, hydrogenation gun separation devices, valves, etc., and are one of the key components for the safe and reliable ope...
