| 英文摘要: |
| In order to solve the problems in the bubble method of safety valve sealing test, such as large manual error and low work efficiency, a new type of
automatic safety valve seal detection system was developed. The system combined with sensing technology, microcomputer control technology and computer technology, to directly
measure the gas volume flow with high precision flow sensor. The signal data was automatically collected and uploaded to the database through the microcomputer measurement and control
system, and was processed by the host computer software. Finally the experimental report was generated automatically. Compared with the traditional bubble method, it is found that the
measurement results of this system are less deviation and more reliable. Besides, this system can realize digital and automatic test, which improves work efficiency for safety valve check
station. |
