固液两相离心泵内颗粒流动特性的研究进展
|
摘要
渣浆泵和泥沙泵等输送固液两相混合物的水泵是泵类中的耗能大户,在工农业各部门中应用广泛。固液两相离心泵的性能和效率受控于泵内的两相流动规律,理解泵内的两相流动规律,对于合理设计和延长泵的使用寿命有重要意义。本文重点阐述了固液两相流泵的研究现状及其进展。在内部流动特性方面介绍了固体颗拉在叶轮和蜗壳内部的流动规律,研究了泵内部过流部件的磨损规律及抗磨措施。并对低比转速固液两相流离心泵研究热点和发展趋势进行了讨论。
As one of high energy consumption pumps,pump used for solid-liquid two-phase mixture transportation,such as slurry pump and mud pump,is extensively used in the hydraulic transportation of solid-liquid mixture through pipes in various fields.Many studies indicate that the performance and efficiency of solid-liquid two-phase centrifugal pump is controlled by the two-phase flow pattern inside the pump,so understanding flow characteristics and abrasion mechanism has important significance to improve the hydraulic design of the impeller for decreasing the abrasion and increasing the service life of the pump.This paper focuses on the research status of solid-liquid two-phase flow pump,the wear rules,anti-wear measures and the internal flow characteristics in impeller and volute casing were analyzed.And research hotspot and development trend of the low specific speed solid liquid two-phase flow centrifugal pump are discussed.
