摘要：
To improve the efficiency and reduce the noise of forward multi-blade centrifugal fans, performance test and flow field measurement with five-hole probe at outlet of impeller were carried out for adjustable casings instead of concealed motor. The result shows that the length, diameter and two-side end-shape of casing have greater influence on the performance and noise of the fans. And the change of fans' performance is mainly caused by the increase of hydraulic loss inside the impeller due to the concealed motor and the low hydraulic efficiency of the impeller.
