关于风机选型的问题，很奇怪

我需要13000方的空气，前端出口压力需要pa，风机进口处有1000pa的负压！
我选的是2台并联4-72 5A 2900转15kw& &标牌说明13000的流量&&3000pa的压力
可是发现气量不够，查曲线不在合理范围内
我有换了2台4-72 5.5A的2900转 非标风机& &
这个风机17000流量下使3100pa
可是使用后功率不到额定的一半&&（22KW）
风箱静压测试有pa
是不是我选型还是选小了！请教各位海友了！

这个应该属于离心通风机。

两台并联我觉得应该选9-19-9D-15KW两台。

并联流量可以叠加的，压头不可以。

选用时应把工况换算成标准状况，再查表选型。
流量不足主要原因两点：
1、管网实际阻力值与计算值相差过大，实际值大于计算值。
2、选择时位考虑风机本身全压值偏差的影响。
