Shell煤气化装置离心泵试车问题分析与处理

针对Shell煤气化装置离心泵的应用,分别分析了岳阳煤气化装置排水泵、安庆煤气化装置热水泵及岳阳和安庆煤气化装置高压工艺水泵在试车过程中出现的扬程偏大、气缚和联锁等问题,结合流体输送机械理论,提出了相应的解决方案,并通过实施后的运行效果,检验了所提方案的正确性与合理性,从而总结出化工装置现场离心泵试车问题的处理方法,可供其他类似项目借鉴。

Analyzing and Solving Problems of Centrifugal Pumps Occurred during the Commissioning of Shell Coal Gasification Plant

The problems of＇ too great head of delivery, air sinuses, interlock, etc., which occurred to the discharge pump in the Yueyang Coal Gasification Plant, the hot water pump in the Anqing Coal Gasification Plant and the high pressure process water pumps in the Yueyang and Anqing coal gasification plants during the commissioning of these plants were analyzed respectively, taking the centrifugal pumps in the Yueyang and Anqing Shell gasification plants as examples. Relevant programs for solving these problems were proposed based on the theory of fluid handling mechanism. The practice of those programs verified their correctness and rationality. The method for solving problems of centrifugal pumps for chemical plants was thus summarized and can be served as a reference for other similar chemical plants.
