| Abstract: | To solve the problem of low precision in pressure control in the low temperature comprehensive performance test of storage tank , a high precision pressure control method was proposed according to the existing test conditions by studying the change of medium in the test. After a slew of experiments and applications, the pressure fluctuates in the low temperature comprehensive performance test of storage tank caused by the evaporation and condensation of the low temperature medium can be rapidly eliminated and thus effectively improve the pressure control accuracy in the cryogenic tank comprehensive tests. |
