PNJ、PNJF型泵系单X单吸离心式衬胶泵,可输送各类不含有尖角的固体颗凿的矿浆。为了减少离开叶轮的液体直接进入泵壳时因冲击而引起的能量损失,在叶轮与泵壳之间有时装置一个固定不动而带有叶片的导轮。导轮中的叶片使进入泵壳的液体逐渐转向而且流道连续扩大,使部分动能X地转换为静压能。多X离心泵通常均安装导轮。蜗牛形的泵壳、叶轮上的后弯叶片及导轮均能提高动能向静压能的转化率,故均可视作转能装置。胶泵2PNJFB衬胶泵副叶轮南汇区输送矿浆浓度不X过65%(重量计),温度不得X过60℃。两种泵结构型式相同,但材质不同,PNJF型泵X于输送有腐蚀性矿浆。根据用途不同,PNJ、PNJF型泵的泵轴分别用X质碳素钢、镍铬钢制成,护套分别为耐磨橡胶、耐磨耐酸橡胶与钢板合制而成,叶轮为铸钢制骨架(25PN、25PNJF型泵为铸铁制肖架)分别外衬耐磨橡胶、耐磨耐酸、橡胶制成。PNJ、PNJF型泵有填料和付叶轮两种不同的密封结构(25PNJ、25PNJF型泵只有付叶轮密封结构)。密封结构一般按填料密封供货。若选用付叶轮密封,订货时必须说明。泵用付叶轮密封时,胶泵2PNJFB衬胶泵副叶轮南汇区进口灌注高度不X过5米水柱(25PNJ、25PNJF型泵不X过1.5米水柱)。2PNJB、2PNJFB的排出口可按45°间隔旋转不同方向。4PNJFB的排出口在270°范围内可按45°间隔旋转不同方向。6PNJB、6PNJFB的排出口在270°范围内可按30°间隔旋转不同方向。25PNJ、25PNJF的排出口可按90°间隔旋转不同方向,在没有特殊说明的情况下,供货一律为垂直向出口。泵的旋转方向,从传动方向看为逆时针旋转。
