| 一、DT脫硫泵概述 DT型脫硫泵主要為吸收塔循環(huán)泵使用，材質基本為高鉻合金，A49，Cr30A等，該系列泵在水力設計、結構設計以及鑄件所用材料上，綜合應用了國內外同類產品的優(yōu)點并加以創(chuàng)新。具有高效節(jié)能、抗磨耐腐、振動小、噪聲低、運行可靠、使用壽命長、維修方便等特點。DT系列脫硫循環(huán)泵的泵殼為單層殼體結構。葉輪與軸采用螺紋連結，軸封采用機械密封。懸架部分采用稀油潤滑形式。過流部件葉輪、蝸殼、后護板等均采用我廠自行研制的抗磨耐腐高鉻合金材料制造。
二、DT脫硫泵應用范圍 該系列脫硫泵廣泛用于電力、冶金、煤炭、建材、化工等行業(yè)，主要是用來輸送含有固體顆粒的磨腐蝕性強的漿體，如廠處理精礦尾礦，電廠除灰渣，選煤廠輸送煤泥和重介選煤、海岸河道采礦作業(yè)輸送礦漿等。其所能處理的重量濃度為：灰漿45%，礦漿60%，漿液中氯離子含量可達60000ppm，漿液的PH值允許在4—13之間, 漿液溫度≤65°C，漿液重量濃度Cw可達60%。 三、DT泵結構示意圖
