The length of the service life of exterior rotor axial flow fan, not only in terms of performance, can make better use outer rotor fan, to protect the outer rotor fan and prolong its service life, you must apply some methods to correct storage and maintenance exterior rotor fan. Below by bolt machinery co., LTD enjoys introduced several schemes for your reference:
1, exterior rotor fan in the running process if found abnormal sound, fan motor fever severely, housing when charged, the phenomenon such as switch trip, can't start, it is necessary to stop the machine immediately to check. In order to ensure safety, don't allow in the fan operation for repair and maintenance should be done after commissioning 5 ~ 10 minutes or so, confirm no abnormal phenomenon to boot.
2, only under the normal operation of the fan is completely can operate, at the same time to ensure the power supply facilities sufficient capacity, voltage stability, it is strictly prohibited to beyond or below the product use, or lack of phase operation, power supply line must be dedicated line, should not use temporary line power supply for a long time.
3, exterior rotor fan often keep the air in using the environment should be unobstructed, dry, clean and tidy. Fan surface clean, inlet and outlet should not have the sundry, regular dust removal fan and the pipeline and other sundry.
4, external rotor fans should be stored in dry environment, avoid motor or motor be affected with damp be affected with damp. Outer rotor fan when in open air, defensive measures. In the process of storage and handling should prevent exterior rotor knock against strong impact or force, so as to avoid damage of fan.
