广西某石英砂矿的开采作业是在水下进行的,对其物料输送(水上和陆地上的水平运距600余米、垂直提升高15米),设计中采用了射流泵输送方案。图1身寸流泵示意图1、喻嘴,2、奋昆合室,3、喉管,4、扩散管,5、吸入管产性试验,取得了较好的效果 The mining operation of a quartz sand mine in Guangxi is carried out under water. The transport of materials (water level and land over horizontal distance of more than 600 meters and vertical lifting height of 15 meters) is adopted in the design. Jet pump delivery scheme is adopted in the design. Figure 1 body flow pump schematic 1, Yu mouth, 2, chamber of enchantment, 3, throat, 4, diffusion tube, 5, suction tube production test, and achieved good results
