1. The ambient temperature should be 75ºC≥-40ºC.

2. The industrial gas passing through the cooling fan is not allowed to contain strong acid, strong alkali and various solutions.

3. Dust and other sundries are not allowed to fall into the fan, so as not to cause the fan to burn and the fan blades to break.

4. Before installation, you should first check whether it is damaged or deformed due to packaging and transportation. If there is damage or deformation, it should be repaired and installed.

5. Then check whether the parts and screws are loose; whether the blades and the air duct collide or shift, if they collide or shift, they should be adjusted before installation.

 

Control characteristics of DC FAN cross-flow fan 040 surge

(1) It can be seen from the test that the surge phenomenon in the unstable working area of ??the cross-flow fan is a serious problem for the normal operation of the cross-flow fan, and the high-speed area should be avoided. This test suggests that the stable working speed of the cross-flow fan should be below 691 r/m in;

(2) The surge phenomenon of the cross-flow fan has a great relationship with the pressure and flow in the test system. When the pressure is strong and the flow rate is small, the surge phenomenon is not easy to occur. On the contrary, when the pressure decreases and the flow rate increases, the fan is prone to surge due to the action of the eccentric vortex;

(3) Although the cross-flow fan has an unstable working area at high speed under certain working conditions, at medium and low speed, the cross-flow fan has the advantages of large flow, uniform and stable lateral airflow, and compact structure.
