本文通过下面几起严重事故说明大型氨制冷装置(包括冷藏库和食品冻结装置)可能出现的安全问题。并提出了防止这些事故和有关抢救工作的一些建议。氨爆炸一个大型压缩机房在凌晨二时左右发生爆炸。由于设计的不完善,使用了15年的某些部件发生疲劳断裂;可能是一台大型立式往复式双级制冷压缩机〔外国制造〕在运行中其汽缸发生液击事故。先是高压级气缸被掀开。致从冷凝器和中间冷却器来的氨大量
This article explains the safety issues that can occur with large ammonia refrigeration units, including cold storage and food freezers, through several serious accidents. And put forward some suggestions to prevent these accidents and rescue work. Ammonia explosion A large compressor room exploded around 2 a.m. Due to imperfect design, fatigue fracture occurred in some parts for 15 years. It may be that a large vertical reciprocating two-stage refrigerant compressor [manufactured in foreign countries] caused a liquid hammer accident on its cylinder during operation. First high-pressure cylinder was opened. To from the condenser and intercooler to a large number of ammonia
