What happens when the electric gourd drops occasionally
Abnormal noise from the steel wire rope electric hoist motor, this kind of circumstance should immediately stop check whether the motor is single-phase operation or damage of bearing, axis of coupling is not straight and sweep chamber failure, these will make the motor has exceptions Sound, for example, when the single phase is running, the whole electrical machine is making a regular "buzzing" noise. When the bearing is damaged, it will be accompanied by a "rumbling" sound that accompanies the bearing. And when the coupling is not right, Even the electric motor was slightly sweeping, and the whole electric machine was buzzing with a great buzz. And from time to time comes the piercing shrill voice.
Back to the way of controlling the noise, the general contactor is malfunctioned, mostly due to ac contactor contactor poor contact, discrepant voltage grade, magnetic core, CARDS, etc., to deal with fault contactor for maintenance, can't repair, must be replaced after treatment can eliminate the noise.
The steel wire rope electric gourds have abnormal sound, such as gearbox or bearing oil, gear wear or damage, bearing damage and so on, should stop check immediately. Some users are wrong to think that a reducer or a bit of lubricating oil can work without a serious malfunction. On one occasion, I company installed 1 electric hoist, installation workers forgot to reducer lubrication, just try one day, high noise reducer, when open the speed reducer, there are a lot of copper powder, gear wear excessive and scrap. In addition, the gearbox is overworn or damaged. On the other hand, the damage of the reducer bearing is similar to that of the motor bearing fault, and it also makes an abnormal noise near the bearing. In order to prevent failure, regardless of the speed reducer gear is damaged, or reducer bearing damage, all need to immediately remove the repair or replacement, eliminate the fault, reduce the noise of wire rope electric hoist.
The drop contact or the broken firearm needs to be replaced in time to prevent burning motors
