一、DT脱硫泵概述
DT型脱硫泵主要为吸收塔循环泵使用，材质基本为高铬合金，A49，Cr30A等，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。DT系列脱硫循环泵的泵壳为单层壳体结构。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形式。过流部件叶轮、蜗壳、后护板等均采用我厂自行研制的抗磨耐腐高铬合金材料制造。
二、DT脱硫泵应用范围
该系列脱硫泵广泛用于电力、冶金、煤炭、建材、化工等行业，主要是用来输送含有固体颗粒的磨腐蚀性强的浆体，如厂处理精矿尾矿，电厂除灰渣，选煤厂输送煤泥和重介选煤、海岸河道采矿作业输送矿浆等。其所能处理的至大重量浓度为：灰浆45%，矿浆60%，浆液中氯离子含量至高可达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至高可达60%。
