风机特点:<../p>
<../p>
4-72-12、 B4-72-12、 4-72、B4-72离心通风机适用于一般工矿、厂房、大型建筑物的室内通风换气,输送空气和其他不自燃、无腐蚀性、对人体无害、不含有粘性物质气体。B4-72型可作为易燃挥发性气体的通风换气用。气体内不许有粘性物质,所含尘车及硬质颗粒物不大于150mg../m3。气体温度不得超过80°C 。<../p>
B4-72型风机的性能与选用件及地基尺寸与4-72型一致,可按其样本选择。该鼓风机结构基本与4-72型相同,№2.8~6A采用B35型带法兰盘与底脚的电动机,№6~12C、D式传动电动机选用该表中与Y系列对应的YB系列,安装型式为B3<../sub>。<../p> 机号<../td> 传动方式<../td> 转速<../td> 流量<../td> 全压<../td> 电动机<../td>
