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。
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能有效地延长寿命。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。
