玻璃钢离心风机失速一般发生在两台风机运行时,由于风压太大或风量太小而引起动叶出口产生涡流而不打风,从而引起负荷偏差大,动叶自动。其现象是,当两个风机并列运行并投入自动控制时,玻璃钢风机的动叶扩大的风管风压下降的一个风机的电流几乎没有变化,另一个(发生失速)风机的电流下降,电流下降的风机轴承温度上升,振动增大。

玻璃钢离心风机

玻璃钢风机失速现象,并联运行的风机失速出现下列现象:

(1)失速风机压头减小,流量增加,电流大幅度下降,出口风温增大;

(2)失速玻璃钢离心风机噪声明显增加,严重时可引起外壳、风道、烟道振动

(3)失速玻璃钢风机振动增大,DCS发出呼吸振动大警报;

(4)投入自动运转时,与失速玻璃钢风机并联运转的风机的电流和容积比大幅增加

(5)在自动状态下,机翼在另一个风向的开度增大。与玻璃钢风机的气喘不同,玻璃钢离心风机失速后风压和流量减少,不发生脉动。
