Reasons for the explosion of the explosion-proof plate in the high-pressure water system

Thread Content

The main reasons for the explosion of the explosion-proof plate in high-pressure water systems are as follows: Equipment-related reasons: Defects in the quality of the explosion-proof plate itself； The blast plate is installed upside down or at an angle. The heat exchanger of the high-pressure washer leaked, allowing high pressure to mix with low pressure, which caused overpressure in the high-pressure water system and led to its rupture. Due to minor leaks in the heat exchanger of the high-pressure washer, the ammonia nitrogen level in the high-pressure water was above the permissible limit, which caused the explosion-proof plate to corrode and thin out, leading to its rupture. Process-related reason: When replenishing water to the high-pressure water system, the pressure of the water supply was too high; the pressure control valve failed to adjust in a timely manner, the safety valve did not activate, or the inert gas in the shell side of the high-pressure washer was not completely removed, resulting in overpressure in the high-pressure water system and subsequent explosion. When water at high pressure is heated and vaporized, or when the temperature rises too rapidly causing liquid slugging, this can lead to the explosion of the explosion-proof plate. The shut-off valve on the high-pressure water pipeline system exiting the high-pressure washer is closed or has a low opening degree, causing overpressure in the high-pressure water and resulting in a burst. The pipeline between the burst disc and the cut-off valve is too long; in winter, the pipeline freezes and expands, causing it to burst. During normal operation, steam tracing or electric heating should be considered to prevent freezing. When parking in winter, it is necessary to open the drain between the burst disc and the shut-off valve in a timely manner to drain the water accumulated in the system, thereby preventing the water from freezing and expanding enough to break the burst disc.
