In the Cross flow blower in china, when the rotational speed is high and the vent area is large, the control force of the eccentric vortex is enhanced, the gas in the cross-flow fan cannot be discharged or inhaled normally, the test system has abnormal conditions, and the cross-flow fan has a surge phenomenon, and there is a surge Vibration period, its specific performance is:
(1) The noise of the Cross flow blower in china increases.
When the cross-flow fan is working normally, the noise is relatively small. However, when the surge phenomenon occurs, there will be a dull humming sound inside the cross-flow fan, and a sharp roaring sound will be issued from time to time, and the sound is relatively loud;
(2) The vibration of the Cross flow blower in china is intensified.
When the surging phenomenon occurs in the Cross flow blower in china, the drive belt of the power trolley vibrates obviously, and the whole test device has obvious vibration phenomenon;
(3) Difficulty in reading Cross flow blower in china.
When the surge phenomenon occurs in the Cross flow blower in china, the value displayed by the micro pressure gauge and the rotational speed torque meter changes rapidly, and the range and amplitude of the change are large, and the change is periodic. In this case, the readings of the test personnel are brought very difficult. Under normal circumstances, the maximum value of the displayed value is the normal working value of the cross-flow fan, and the surge phenomenon almost disappears, but in a cycle, it is short-lived and very unstable, and the minimum value of the displayed value is the reading that occurs when the surge phenomenon is the most serious.
