我矿使用的3PN泥浆泵,主要用于输送浓度为18～35％、粒度不大于60网目的硅砂尾砂矿浆。采用的叶轮为开式叶轮(图1)。在生产使用过程中,由于这种叶轮没有前后轮盘,
The 3PN mud pump used by mine is mainly used for transporting silica sand tailings pulp with a concentration of 18-35% and a particle size of not more than 60 meshes. The impeller used is an open impeller (Figure 1). In the production process, because this impeller does not have front and rear roulette,
