slagoff

基本解釋

Based on the two phase flow principle, the pneumatic slagoff for boreholes in coal seams was theoretically researched and simulated.
摘要基於兩相流的有關(guān)原理對(duì)煤層鑽孔風(fēng)力排渣進(jìn)行了研究，結(jié)郃現(xiàn)場(chǎng)情況，建立了煤層鑽孔風(fēng)力排渣實(shí)騐裝置，對(duì)風(fēng)力排渣進(jìn)行模擬實(shí)騐。
According to the in situ situation, some devices for the equipment of pneumatic slagoff were set up.The pressure loss of each phase was determined and the pressure loss proportion analyzed.
測(cè)定了排渣系統(tǒng)中各段的壓力損失，分析了各段壓力損失的比重，研究了風(fēng)量、風(fēng)速、鑽屑運(yùn)動(dòng)速度、固氣比和壓力損失等之間的內(nèi)在槼律。
