一、LY标准液下泵概述
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�；蛳宋母骼辔鬯�。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化工液下泵结构特点
LY型长轴液下泵接轴结构安全可靠
转子部件可以轴向调整
转子部件采用多点支撑，泵运转安全可靠。
滑动轴承采用外润滑或自润滑
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
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。
从电机端看，泵为顺时针方向旋转。
三、LY长轴液下泵型号意义
LY40-160
LY--长轴液下化工泵
40--出口直径mm
160--叶轮名义直径mm
