平桂型砂泵已经有三十余年的历史。它具有结构简单,便于制造安装和价廉等特点。它是矿山企业运送矿浆、输送精矿、排泄尾矿的有效设备。尤其是叶轮流道宽,能够扬送较大粒度矿浆物料,因此用于矿山水力开采是比较理想的矿浆输送设备。然而,在长期生产运行中也暴露出一些弱点。主要表现在砂泵水力设计差,效率低,运行精度 Ping-gui sand pump has more than thirty years of history. It has a simple structure, easy to manufacture and installation and low cost. It is an effective equipment for mining enterprises to transport ore pulp, deliver concentrate and excrete tailings. In particular, the impeller runner is wide, which can lift large size slurry material, so it is an ideal pulp conveying equipment for mining hydraulic mining. However, some weaknesses have also been revealed during long-term production runs. Mainly in the sand pump hydraulic design is poor, low efficiency, operating accuracy
