1 Use environment should always be clean and tidy, fans kept clean on the surface, the inlet and outlet should not be occupied, regularly remove dust and other debris inside blower and pipelines.
2 Only in fans fully functioning under normal circumstances, colleagues capacity sufficient to ensure power supply facilities, voltage stability, no phase-missing running, must be a dedicated line of power supply line, should not be a long-term temporary line power supply.
3 Fan runs during found abnormal sound, the electrical fan charged, switch tripping, severe fever, shell will not start, you should immediately check out. In order to ensure a safe, fan operation is not allowed in the repair, maintenance should be carried out after commissioning of five minutes or so to confirm that no anomalies then start running.
4 According to the operating environment under the conditions from time to time to supplement or replace the bearing grease (closed motor bearing service life period having to replace the grease), in order to ensure good lubrication fan is running, refueling frequency not less than 1000 hours/times sealed bearings and motor bearings, come on ZL-3 one-third of lithium base grease filled bearing inner and outer rings, no shortage of oil operations.
5 Axial-flow fan should be stored in a dry environment, avoid motor damp. Fans at the time of open storage, and defenses. Fan in storage and handling procedures shall prevent bump to prevent wind damage.
