发布日期:2018-07-13 作者: 点击:

  离心风机厂家--通风机的主要性能参数。通风机性能是在标准状态下的性能。标准状态即指风机进口处气体压力为101325Pa,温度20℃,密度1.205g/m³,相对湿度为50%。

  一、风量q单位时间内从进口处吸入气体的体积,也称为体积流量,单位m³/h,m³/s。

 二、通风机的全压是指单位体积气体流过风机叶轮所获得的能量。

 三、通风机的转速指每分钟叶轮的旋转圈数,单位r/min。

 四、通风机的功率指原动机的输出功率称风机的轴功率。单位时间内从风机中所获得的有效能量,成为有效功率。单位也是KW。

 五、通风机的全压效率指全压有效功率与轴流功率的比值。
