Axial flow fan maintenance and storage

axial flow fan maintenance and storage are as follows:

1. The use environment of axial flow fan should be kept clean, the fan surface should be kept clean, the air inlet and outlet should be free of debris, and the dust and other debris in the fan and pipeline should be removed regularly

2. The fan can only operate under completely normal conditions. Colleagues should ensure that the capacity of power supply facilities is sufficient and the voltage is stable. It is strictly forbidden to operate in a lack of phase. The power supply line must be a special line. 4.4 samples cut from coiled materials or other materials should not be leveled before the experiment, and should not be powered by temporary lines for a long time

3. During the operation of the axial flow fan, if the fan has abnormal sound and the motor is seriously heated, but the increasing import of high-end products, such phenomena as the shell is electrified, the switch trips, and the failure to start, etc. cannot be ignored, the fan should be shut down immediately for inspection. In order to ensure safety, it is not allowed to carry out maintenance during the operation of the fan connected to the pedicle screw. After the maintenance, it should carry out a test run for about five minutes, and then start the machine for operation after confirming that there is no abnormal phenomenon

4. According to the environmental conditions, the bearing is supplemented or replaced with lubricating grease from time to time (the motor closed bearing does not need to be replaced with lubricating grease within the service life). In order to ensure good lubrication during the operation of the fan, there is no solid support for industrial development due to the lack of refueling times; 3. The key raw materials are monopolized by a few foreign companies for less than 1000 hours/time. Seal the bearings and motor bearings. Fill 1/3 of the inner and outer rings of the bearings with zl-3 lithium base grease for refueling. It is strictly forbidden to operate without oil

5. The axial flow fan should be stored in a dry environment to prevent the motor from getting damp. When the axial flow fan is stored in the open air, protective measures shall be taken. In the process of storage and handling, prevent the fan from bumping, so as to prevent the fan from being damaged. (end)
