- 摘要:
- 固液两相介质离心泵主要用于煤化工、冶金、电力、石油化工、市政工程等领域，用于输送含灰渣、固体杂质和浆体的介质，其扬程一般不超过80 m。超过80 m扬程的高压高扬程固液两相介质离心泵可以用作煤气化工业中的激冷水泵、洗涤塔循环泵和石化行业PTA装置中的TA浆料供料泵，在这类泵的设计中有些需要特别关注的技术特点。从转子刚性、轴向力平衡、过流部件设计的适用性、支撑系统的稳定性、机械密封设计的可靠性等几个方面论述了高压高扬程固液两相介质离心泵的设计原则。
- Abstract:
- The solid-liquid two-phase centrifugal pump is mainly used in coal-chemical industry, metallurgical industry, thermo power plant, petrochemical industry and municipal engineering to transport the medium with slag, solid impurities and slurry. Generally speaking, its lift is not more than 80 m. The high-pressure & high-lift centrifugal pump for solid-liquid phase mediums, whose lift is more than 80 m, can be used as chill water-pump and scrubber circulation pump in coal-gasification industry, and TA slurry feeding pump in PTA industry. More attention should be paid to some technical features in design of these pumps. In this article, some design philosophies of high-pressure & high-lift centrifugal pump for solid-liquid phase mediums are described in the aspects of rotor rigidity, axial force balancing, flow passage component's applicability, brace's stability and mechanical
