产品概述
LG-B型立式多级离心泵是根据高层建筑恒压供水及消防行业的产品。LG-B型泵由电机和泵联结而成,泵轴与电机轴用夹壳式联轴器联结,确保泵与电机绝对同轴使泵运行平稳、噪音低等现象。电机为Y型三相异步电机,方便用户更换,整体为刚性连接,使用时无需校正。轴封采用机械密封,泵为便拆式结构方便更换机械密封。 泵旋转方向从电机端向下看为顺时针方向转动。
产品特点
1、泵结构紧凑、体积小、外形美观,其结构决定安装占地面积小,如加上防护罩可置于户外使用。 2、叶轮直接安装在电机轴上,从而保证泵的同心度,因而增强了泵的运行稳定性和延长泵的使用寿命。 3、轴封采用机械密封或机械密封的组合,采用优质的质合金密封环,增强了密封的耐磨性有效地延长寿命。4、安装检修方便,无需拆动管路系统。泵进口和出口为相同口径,简化了管路的连接。5、可根据流量和扬程的需要采用泵的串、并联运行方式。6、可根据需要,吸入口和吐出口可安装成0°、90°、180°、270°几个不同方向以满足不同的连接场合。7、泵扬程可根据需要增减水泵级数并结合切割叶轮外径予以满足,而不改变安装占地面积。
产品用途
LG-B型立式多级离心泵特别适用于住宅、宾馆、办公大楼等高层建筑恒压供水、消防、喷淋给水设备配套用泵;也适用于化工流程冷却塔的自动补水;系统稳压、生产工艺循环用水、远距离输送、锅炉给水等给水设备之用。可输送的液体为常温(<80℃)(热水型可输送温度小于105度的介质)清水或物理、化学性质类似于水的常温介质。
