Embodiment Construction
[0022] The present invention will be further described below in conjunction with the accompanying drawings.
[0023] The hydrogen storage tank detection system includes a hydrogen charging and discharging control system 2 , a data recording system 3 and a temperature control system 4 .
[0024] The hydrogen filling and discharging control system 2 controls the hydrogen source 5, the electromagnetic control valve 9 and the vacuum pump 15 to complete the filling and releasing of hydrogen, as well as the treatment of the residual gas in the system. The data recording system 3 records the data measured by the flow detectors 7 and 14 , the pressure sensors 13 , the strain gauges 20 , and the temperature of the temperature control cabin 10 in real time. The temperature control system 4 can change the temperature of the temperature control cabin 10 to adjust the experimental environment temperature of the hydrogen storage tank 11 .
[0025] like figure 1 As shown, the carbon fiber ...

A performance testing device for a carbon fiber winding hydrogen storage tank for a hydrogen energy automobile comprises a hydrogen charging and discharging control system, a data recording system anda temperature control system. When the use performance of the hydrogen storage tank is tested, the hydrogen charging and discharging control system controls the hydrogen source to release hydrogen. After being filtered by the filter, the hydrogen is filled into the hydrogen storage tank through the inflation pipeline. When the filled hydrogen reaches a set value, hydrogen filling is stopped, thehydrogen filling and discharging control system opens the electromagnetic control valve on the exhaust pipeline, the hydrogen is released through the exhaust pipeline and stops being released when reaching the set value, the discharged hydrogen enters the recovery device to be recovered, the hydrogen is recycled, hydrogen filling and discharging operation is repeated, and the use performance and the mechanical performance of the hydrogen storage tank are tested. The hydrogen storage tank is arranged in the temperature control cabin, and the environment temperature of the hydrogen storage tankcan be changed through the temperature control system.
Description
technical field [0001] The invention relates to the field of hydrogen storage performance testing, in particular to a performance testing device for carbon fiber winding hydrogen storage tanks for hydrogen vehicles. Background technique [0002] At present, the energy used by humans is mainly fossil energy such as coal, oil, and natural gas. However, such fuels are non-renewable and will decrease with the exploitation of reserves, and the use of such energy will cause serious pollution to the environment. Therefore, human beings urgently need to find new clean and efficient energy sources to replace traditional energy sources. Due to the advantages of rich hydrogen content and no pollution to the environment after use, hydrogen energy has begun to be the object of research. At present, the production and application technology of hydrogen has matured, and the main constraint to the development of hydrogen energy is the storage of hydrogen. The storage methods of hydrogen e...
