Fan Maintenance And Storage

- Jul 12, 2018 -

Fan maintenance and storage:


1.The use environment should be kept clean and tidy, the surface of the fan should be kept clean, and there should be no debris in the inlet and outlet. Regularly remove dust and other debris from the fan and piping.


2.It can only be operated under the condition that the fan is completely normal. At the same time, it is necessary to ensure that the power supply facilities have sufficient capacity, the voltage is stable, and the phase loss operation is strictly prohibited. The power supply line must be a dedicated line, and the temporary line should not be used for long-term power supply.


3.During the operation of the fan, the fan is found to have abnormal sound, the motor is seriously heated, the outer casing is charged, the switch is tripped, and the switch cannot be started. In order to ensure safety, maintenance is not allowed while the fan is running. After the inspection, it should be operated for about five minutes to confirm that there is no abnormality and then turn on the machine.


4.According to the use of environmental conditions, the bearing should be replenished or replaced with grease (the motor closed bearing does not need to be replaced during the service life), in order to ensure good lubrication during the operation of the fan, the number of refueling is not less than 500 hours/time. (The visual center of the oil window is less than two-thirds, more than one-half). All oils need to be replaced before the first oil change. Closed bearings and motor bearings are filled with ZL-3 lithium-based grease. 2/3 of the inner and outer rings of the bearing. Oil shortage is strictly prohibited.


5.The fan should be stored in a dry environment to avoid moisture in the motor. When the fan is stored in the open air, it should be protected from rain. Prevent fan blows during storage and handling to avoid damage to the fan.


6.If the fan is not used for a long time, the main shaft and other components must be operated within three months, and the rotor should be rotated by 120 to 180 degrees, so that the spindle will not be deformed or even bent due to long-term rest. If the fan is not used for 6 months, the oil needs to be replaced when starting up again.


7.In the low temperature environment, the fan must pay attention to the antifreeze problem of the fan. When the fan is deactivated below 0 °C, the cooling water inside the bearing box should be drained clean. Otherwise, the cooling water will freeze and the volume will expand, which will cause the bearing box to crack.


8.The motor needs to be protected from rain and moisture.
