I would like to ask why the electric hoist in the operation of the abnormal sound?
Electric hoist in the operation of the issue of "hum" noise, the whole motor issued a harsh voice, how does this deal with this?
Net friend replies:
Electric hoist in the operation, if the abnormal noise, should immediately stop, check the motor is single-phase operation, or bearing damage, the coupling axis is not correct and "sweep chamber" and other failures, which will make the motor abnormal sound, The sound of the location and the high and low sound and different, single-phase operation, the entire motor issued a regular suddenly strong and weak "buzzing" sound; and bearing damage, will be near the bearing, issued with "slightly deng - slightly deng" Buzzing "sound; and the coupling axis is not correct, or the motor slightly swept the chamber, the entire motor issued a very high" buzzing "sound, and sometimes accompanied by sharp harsh sound. In short, should be based on the different noise, find fault, one by one overhaul to restore the normal performance of the motor, when the motor failure is not handled, the use of gourds, hoping to help you.
When the electric hoist abnormal noise occurs, issued a "hum" noise, the contactor is generally a fault (such as contactor contacts poor contact, voltage level does not match, the core card, etc.), should be fault contactor repair , Can not be repaired must be replaced, after processing, the noise itself to eliminate.
