1. Precautions in the installation process of axial fan

( 1 ) If the axial flow fan is installed on the roof , the installation foundation shall be higher than the roof , and the surface thereof shall be flat , so that the problems such as water leakage and the like can be avoided . In addition, it is necessary to bury the anchor bolts in order to prevent the foundation from loosening, which will affect the normal operation and use of the fan.

( 2 ) the base of the axial fan must have a rubber plate between the base and the foundation, which can effectively reduce the vibration of the fan in operation and avoid the problems of shedding of these parts such as anchor bolts and so on at the same time.

( 3 )The impeller in axial flow fan is an important part, so it should be treated with emphasis. Before the operation of the equipment, the necessary inspection should be carried out, mainly to see if the impeller can be rotated normally. If there is no problem in the inspection, it can be started to use. After that, the test operation of the fan is carried out. First click the motor to check if the rotating direction of the impeller is correct, the axial flow fan can start normal operation.

( 4 ) After the axial flow fan has been continuously running for 72 hours , the basic inspection shall be carried out . After it has been operated for half a year , it shall check whether it is damaged or not .

 

2. Do axial flow fans need 3c certification ?

This is also an important certification for the fan, the product can not be put into the market for sale if without it.

 

3. Switch and ground height for Axial Fan

Which type of switch the axial flow fan uses, mainly depends on the fan power. If the fan power is small, use the ordinary switch. If the power of the fan is large, the magnetic starter can be used, that is, the button is added to the AC contactor. And the height of the switch from the ground in the axial fan mainly depends on whether it is convenient to use and whether it is suitable in size .http://www.jnblower.com/
