一 泵的用途及适用范围DT系列大型脱硫循环泵（DN≥300mm）为轴向吸入、单级、单吸、悬架离心式结构该系列泵在水力设计、结构设计以及铸件所用材料上，综合应用了国内外同类产品的优点并加以创新具有高效节能、抗磨耐腐、振动小、噪声低、运行可靠、使用寿命长、维修方便等特点泵的综合性能居国内领先水平可广泛用于火电、炼铝和炼油等行业的脱硫系统输送石灰石或石膏浆液浆液中氯离子含量最高可达60000ppm，浆液的PH值允许在4—13之间, 浆液温度≤65°C，浆液重量浓度Cw最高可达60%二 泵的结构特征1 总述DT系列大型脱硫循环泵的泵壳（蜗壳）为单层壳体结构叶轮与轴采用螺纹连结，轴封采用机械密封悬架部分采用稀油润滑型式过流部件叶轮、蜗壳、后护板、入口短管均采用我厂自行研制的抗磨耐腐高铬合金材料制造其详细结构见图1 / 文档可自由编辑打印1、叶轮2、入口短管3、蜗壳4、后护板5、机械密封6、拆卸环7、悬架8、轴承体9、轴10、调整螺栓11、压紧螺栓12、螺栓13、支架14、螺柱图1 DT系列大型脱硫循环泵结构图2 叶轮（1） 前盖板背叶片的设计，可防止大的颗粒进入到叶轮与入口短管间的间隙中2） 后盖板背叶片的设计，可减小轴向力，阻挡大颗粒进入机械密封的腔体。

3） 叶轮上排气孔的设计，可以使机械密封的腔体内介质形成流动，带走气体，防止机械密封干磨擦3 蜗壳 蜗壳壁厚能够承受足够的压力和磨损4 后护板（1） 后护板通过螺栓固定在悬架上，便于拆装2） 装单端面机械密封的后护板设计成锥形口，便于浆液及时从机械密封室中排出，防止泵停车后长时间不用，浆液附着在机械密封上损坏机械密封 5 入口短管由于其具有很强的抗磨损能力，保证了流道长时间的平滑和完整由此也帮助延长了叶轮的使用寿命 6 轴承体组件 。
