一、LY长轴液下泵概述
LY型长轴液下泵是一种立式离心泵，适用于化工﹑石油﹑电力﹑冶金﹑制药﹑造纸﹑环保等多个行业部门，可用来进行对有腐蚀性液体，含有一定量固体颗粒液体的输送。是我厂选用国内目前的水力模型设计而成,高效节能稳定是LY液下泵的优点。
LY/LYO/LYG系列长轴液下泵，选用国际优秀的水力模型，泵设计和制造按AP1610VS4型执行，泵轴由泵盖和滑动轴承体内的滑动轴承支承，上轴承采用耐磨轴承，采用锂基润滑脂润滑。该系列泵适用于输送各种腐蚀性液体和清水，同时也适用于输送含有颗粒或纤维的各类污水。LY/LYO型其输送介质温度范围为-20℃~+120℃，LYG型输送介质可达+400℃，工作压力可达1.6MPa。
二、LY长轴液下泵结构特点
1.LY型长轴液下泵接轴结构安全可靠
2. 转子部件可以轴向调整
3.转子部件采用多点支撑，泵运转安全可靠。
4.滑动轴承采用外润滑或自润滑
5.泵起动时，叶轮已浸没在介质中，因而起动容易，不存在排气抽空问题
6.采用双端蜗壳泵体（口径80mm上），转子部件受径力小，轴挠度小，滑动轴承磨损小，寿命长。
7.从电机端看，泵为顺时针方向旋转。
