为了适应钻探设备轻便化的要求,我们在设计北京100-1型钻机时,设计了与之配套的80/15型轻便冲洗泵。1966年初,进行了样品试验,在深度为139米的钻孔(水平钻)施工中,用它抽送冲洗液,效果良好。该孔冲洗液为泥浆,最大粘度50秒。此泵属立式双缸单作用柱塞泵类型,采用球阀及 In order to meet the drilling equipment lightweight requirements, we designed the Beijing 100-1 drilling rig, designed with its accompanying 80/15 light wash pump. At the beginning of 1966, a sample test was carried out. When drilling at a depth of 139 meters (horizontal drilling), the rinsing liquid was pumped to work well. The hole rinse liquid slurry, the maximum viscosity of 50 seconds. This pump is a single-acting vertical two-cylinder piston pump type, the use of ball valves and
