(1) As can be seen from the test, "Cross Flow Fan" workspace appears unstable surge phenomenon is a serious problem in cross-flow product to function properly, it should avoid high-speed zone. This test is recommended that the cross-flow stable operating speed of the machine product shall be 691r / min or less;
(2) "Cross Flow Fan" appears surge phenomenon has a great relationship with the test system pressure, flow rate. Strong pressure, the flow rate of less prone to surge phenomenon, whereas as the pressure decreases when the flow rate increases, the eccentric vortex blower role prone surge phenomenon;
(3) "Cross Flow Fan" Although the presence of certain conditions at high speed instability work-space, but in low-speed, cross-flow fan flow rate, gas flow across a uniform and stable compact structure coupled with the advantages are quite obvious .
