AI Technical Summary
Alkaline electrolyzers are prone to alkali and gas leaks during operation, which can lead to damage or even explosion of the electrolyzer and shorten its service life. Therefore, it is necessary to monitor the deformation of the disc springs online in real time for early warning and timely maintenance.
An instrument for monitoring disc spring deformation, such as an infrared rangefinder, laser rangefinder, ultrasonic rangefinder, or radar rangefinder, is installed on the alkaline water electrolysis cell to monitor the amount of disc spring deformation. The electrolysis cell is then stopped by a limit switch or other distance measuring instrument to ensure safety.
It enables safety early warning and timely maintenance of electrolytic cells, thereby improving the operational safety and service life of electrolytic cells.
