| 摘 要： | 分析冷氨泵低速运行时打量突然下降的主要原因是由于泵打量过低，不足以将热量带走，液氨在泵的某一级或几级入口过热汽化造成的。根据机组已知的设计参数计算实际工况下冷氨泵在2608r／min转速运转时，为保证泵内液氨不汽化，散热所需的最小流量为13．54m^3／h。

| Abstract: | Aiming at a sudden drop of pumping capacity of cold-ammonia pump under running at a low speed, the analysis confirms that this is caused by an over-heat vaporization of liquid ammonia at the suction of one stage or at the suctions of some stages owing to |
