不銹鋼混流泵
一、DT不銹鋼混流泵概述
DT型不銹鋼混流泵主要為吸收塔循環(huán)泵使用，材質(zhì)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(lèi)產(chǎn)品的優(yōu)點(diǎn)并加以創(chuàng )新。具有高效節能、抗磨耐腐、振動(dòng)小、噪聲低、運行可靠、使用壽命長(cháng)、維修方便等特點(diǎn)。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(guò)流部件葉輪、蝸殼、后護板等均采用我廠(chǎng)自行研制的抗磨耐腐高鉻合金材料制造。
二、DT不銹鋼混流泵應用范圍
該系列不銹鋼混流泵廣泛用于電力、冶金、煤炭、建材、化工等行業(yè)，主要是用來(lái)輸送含有固體顆粒的磨腐蝕性強的漿體，如廠(chǎng)處理精礦尾礦，電廠(chǎng)除灰渣，選煤廠(chǎng)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%，漿液中氯離子含量高可達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高可達60%。
