PBG立式管道屏蔽泵为立式水泵,电泵有水泵和屏蔽电动机（以下简称电机）两部分组成。水泵部分主要零部件叶轮、泵体、密封环,电机部分主要零部件有定子、转子、屏蔽套、轴承座、轴承、推力盘、冷却管、放气阀等零部件组成。
屏蔽泵电机选用H级绝缘绕组。转子由不锈钢轴和铸铝转子组成。为了防止输送液体进入定子和腐蚀转子,在定子内径及转子表面分别用不锈钢屏蔽套密封。
密封性：泵体法兰与电机法兰连接处,机座与轴承座及定子屏蔽连接处均有耐热O型密封圈密封。
屏蔽泵叶轮悬臂安装在电机转轴上,由键和螺母予以固紧。
润滑与冷却：采用外循环。当泵工作时,由电泵出口处引出少量液体经过冷却管、后轴承与轴颈间隙、定、转子间隙、前轴承与轴颈间隙、叶轮后口环组成一循环回路（单级）、级叶轮进口环组成一循环回路（多级）。
■PBG立式管道屏蔽泵型号意义：
■PBG立式管道屏蔽泵工作条件：
1、屏蔽泵输送流体不应含有体积比超过0.1%和粒度大于0.2mm的固体颗粒；
2、电源额定电压为380V,频率为50Hz,三相交流电；
3、输送液体的温度≤120℃；
4、屏蔽泵系统压力不超过1.0MPa,不小于50Kpa；如超过请订货时注明；
5、环境温度不超过40℃；
6、海拔不超过1000mm；
7、电动机为鼠笼型,适用于满压起动,如果电原容量不足以满压起动时,则可采用降压启动。
■PBG立式管道屏蔽泵产品用途：
PBG立式管道屏蔽泵广泛应用于暖通空调空调冷热水循环、工业、城市生活用水、管道增压、远距离送水等场合,变换材质的派生产品更可适用于石油、化工、制药、食品、制冷等。高、低温,高压各种场合。
