Maintenance and storage method of centrifugal fan

 Centrifugal fan depends on the mechanical energy input to improve the gas pressure and exhaust gas machinery.

Centrifugal fans are widely used in the ventilation, dust removal and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings, the ventilation and induced air of boilers and industrial furnaces, the cooling and ventilation of air conditioning equipment and household electrical equipment, the drying and selection of grain, the inflation and propulsion of wind tunnel air source and hovercraft, etc.
Maintenance and storage of centrifugal fan:
1. The use environment should always be kept clean, the surface of centrifugal fan should be kept clean, there should be no debris at the air inlet and outlet, and the dust and other debris in the fan and pipeline should be removed regularly.
2. The centrifugal fan should be stored in a dry environment to avoid moisture on the motor. When the fan is stored in the open air, there should be defensive measures. In the process of storage and handling, the fan should be prevented from collision to avoid damage to the fan.
3. The centrifugal fan can only be operated under complete normal conditions. At the same time, the capacity of power supply facilities should be sufficient and the voltage should be stable. It is strictly forbidden to run without phase. The power supply line must be special line, and temporary line should not be used for long-term power supply.
4. During the operation of centrifugal fan, abnormal sound of fan, serious heating of motor, electrification of shell, tripping of switch and failure to start shall be stopped immediately for inspection. In order to ensure safety, it is not allowed to carry out maintenance during the operation of the fan. After maintenance, the test run should be carried out for about five minutes, and the machine can be started again after confirming that there is no abnormal phenomenon.
5. According to the use of environmental conditions, the bearing grease should be supplemented or replaced from time to time (the motor closed bearing does not need to be replaced within the service life). In order to ensure good lubrication during the operation of the fan, the number of oil filling should not be less than 1000 hours / time. The zl-3 lithium-based lubricating grease should be used to fill 1 / 3 of the inner and outer rings of the bearing. It is strictly forbidden to run without oil.
