Sum-Up of Operation of Drastic Hydrolyzer for Urea 尿素深度水解装置运行总结
Analysis of ineffectiveness of the seal of the hydrolyzer feed pump and its modification 水解塔给料泵机封失效分析及改进
The main hydrolyzer, which is a vibration ball mill with 1000 1. capacity, was greatly improved in all respects after repeated tests and modifications. It endured the vibration strength of 10 g in a long trial. 主水解设备1000升振动磨先后经过三次设计和试制,在各方面取得了关键性改进,承受了振动强度10g的长期考验。
This paper analyzes the reasons for frequent ineffectiveness of the seal of the hydrolyzer feed pump and makes some technical modifications which prolong its maintenance period and improve the economic benefits 分析水解塔给料泵机封频繁失效原因,进行技术改造,延长了检修周期,取得较好经济效益
