武钢炼铁厂二制粉ＣＤ型仓式泵扩容改造工程中，采用新工艺和新材料研制新型大容积仓式泵，增设气体流化漏斗、按喷吹罐的控制方式配置供气管路、利用微孔烧结板制作大面积流化床，并且采取了多种旨在增加设备结构强度的措施。新型仓式泵系统投产后，运行指标良好，与改造前相比，输送能力提高２倍以上，输送耗气量减少约５０％ 。 In the expansion project of CD powder bin type warehouse pump of WISCO Ironmaking Plant, a new type of high-volume bin pump was developed by adopting new technology and new materials, a gas flow funnel was added, gas supply pipelines were arranged according to the control mode of the injection canister, Microporous sintered plates make large-area fluidized beds and take various measures aimed at increasing the structural strength of the equipment. The new bin pump system put into operation, operating indicators are good, compared with the pre-transformation, transmission capacity increased more than 2 times, the transmission of air consumption reduced by about 50%.
