Information

　　Cross flow blower in china have very complex internal structures. Although the impeller is symmetrical in the circumferential direction, the airflow is asymmetrical, and its relative and absolute velocity fields are unstable.

Cross flow blower in china

　　In theCross flow blower in china, there is a vortex on the inner side of one side of the impeller circumference that can control the flow of the entire airflow, which is the so-called eccentric vortex of the cross-flow fan. The center of the vortex is somewhere in the inner circumference of the impeller, and it moves along the circumferential direction with the different throttling conditions.

　　Under certain working conditions, theCross flow blower in china can not be discharged or inhaled normally due to the enhanced control force of the eccentric vortex when the cross-flow fan is at high speed.

　　In theCross flow blower in china, if the vent area is small, the resistance of the resistance layer is large, and the flow in the pipeline is small, so the working requirements of the cross-flow fan are lower, and the effect of the eccentric vortex is not obvious at small flow.
