Communication: matters need attention for installation and maintenance of the fan

Number of visits: Date:2017-03-29

For any kind of mechanical equipment, installation and maintenance are the key to the normal operation of mechanical equipment, fans are not listed outside. So, what do we need to pay attention to the installation of the ventilator and how to maintain it?

Installation Precautions:

1, out of the box to check the fan parts are complete, whether the bumps outside the chassis, with particular attention to whether the head rectifier bumps deformation, the parts are connected closely, whether the damage of the blade motor, impeller rotation is flexible, The problem should be repaired and adjusted.

2, check the installation of the fan foundation, it must have sufficient strength and stiffness to ensure that the load can withstand the operation of the fan, and check the foundation and fan connection size is consistent with the design requirements.

3, the fan lying to install the shock absorber through the coupling bolts fixed to the fan base, with the center of the high adjustment pad to adjust the level of the shock absorber, with a fixed bolt on the foundation has been welded on the connection plate , Such as the fan due to seismic and other reasons without shock absorber, then the fan base on the screw hole and the embedded bolts can be directly connected.

4, side wall installation of the basic requirements of the fan installation and lying on the same installation, but the installation bracket made of inclined arm support, the bracket should have sufficient strength and stiffness, 10 # or more fans should not use this installation The

5, hanging installation of the first shock absorber and fan bolts connected into one, shock absorber symmetrical installation, arranged on both sides of the fan center of gravity, the fan will be directly inserted into the suspension bracket, hanging bracket height, depending on the actual space distance Customized by the user, more than 16 # fan generally do not use this type of installation.

6, vertical installation fan vertical installation method and lying on the installation of the same, the strength of the fan foundation and stiffness requirements more stringent.

7, the fan and the pipe at both ends of the connection must be flexible joints to isolate the vibration and protection of the fan.


1, the use of the environment should always keep clean, the fan surface to keep clean, into the outlet should not have debris, regularly remove the fan and pipe dust and other debris.

2, only in the fan under normal circumstances can be run, and to ensure adequate capacity of power supply facilities, voltage stability, is strictly prohibited operation, power lines must be dedicated lines, should not be used for long-term temporary power supply.

3, the fan in the running process found that the fan has abnormal sound, the motor serious fever, shell live, switch trip, can not start the phenomenon, should immediately stop checking. In order to ensure safety, do not allow the operation of the fan in the maintenance, maintenance should be tested after about five minutes to confirm that no abnormal phenomenon and then start running.

4, according to the use of environmental conditions from time to time on the bearing to add or replace the grease (motor closed bearings in the life of the period do not have to replace the grease), in order to ensure the fan in the course of running a good lubrication, the number of refueling not less than 1000 hours / Times closed bearings and motor bearings, fueled with zl-3 lithium-based grease filled with inner and outer bearings 1/3; is strictly prohibited lack of oil operation.

5, the fan should be stored in a dry environment, to avoid motor damp. Fan in the open storage, there should be defensive measures. In the storage and handling process should prevent the fan bump, so as to avoid damage to the fan.

In summary, in order to be able to ensure the normal operation of the axial fan, we need to do the installation and maintenance. The correct installation is to ensure that the basis of operation, the future maintenance and maintenance is to extend the life of the key, so can not carelessly.
