高压氨泵的设计缺陷和改进办法

Faults in Design of High Pressure Ammonia Pump and Its Modification

高压氨泵因设计条件错误造成的缺陷， 导致在化工试车中不能正常使用。外方进行了改造仍不成功， 中方对该泵进行了系统的分析研究， 剖析了该泵达不到设计性能的关键原因， 据此对高压氨泵进行改造后， 满足了生产的需要。

A foreign made high pressure ammonia pump was failed to run in normal rate due to fault design parameters in a test run of the plant. Chinese engineers found the key cause after analysis. Now modified pump can meet the requirement.
