摘要
新的催化裂化流程(FCCU),含更高的硫,更重的原油,要求更新催化剂来保持效率,对油浆泵的冲刷和腐蚀更严重,导致过流部件的磨损、腐蚀、结焦等,普通的流程泵寿命很短,提供新型的塔底油浆泵已是刻不容缓。针对原型油浆泵使用中出现的严重的磨损问题,研制了一种新型特种高温全衬里油浆泵。文章详细介绍了这种新型油浆泵的特殊结构、设计思路、特种金属材料在其主要零部件的组合运用,以及在九江石化炼油厂的催化裂化装置(FCCU)中的使用情况,并与原用250PY-100油浆泵的主要技术性能进行了比较。该装置投入九江石化炼油厂催化裂化装置中使用,性能良好。
The new process of catalyst cracker, which deals with crude petroleum with more sulphur and larger density, requires a new catalyst pump to remain high efficiency. However its severe abrasion, erosion of the main parts that fluid flow through and coking action on its surface make the useful life shortened. A new type of pump aiming at solving the problems R&D. The peculiarity in structure, design method, the makeup and application of special metal material and some information about its use in Jiujiang River petrochemical oil-refine factory are introduced. The comparison of its running performance with former pump 250py-100 is also given.
