The electric hoist operates in a state of abnormal sound
- Jun 21, 2018 -

Electric hoist run-time sound of three kinds of condition: electric hoist a lot of trouble, such as manipulation of the electrical appliances, motor and reducer, flush, often accompanied with abnormal noise, the noise of the bearing and the concave and convex and sound don't vary according to the problems for different reasons, inspection, want to listen to see more, can use or noise according to the fault characteristics, concluded that announced the noise bearing, find and check the problem.

(1) abnormal noise occurred in control circuit, announced the hum of the noise, the general is a problem on contactor contactor contactor poor contact (such as communication, discrepant voltage grade, magnetic core, CARDS, etc.), to deal with trouble contactor for inspection, cannot check when necessary to replace, after processing, to eliminate the noise.

(2) the motor announced that abnormal noise, it is necessary to stop the machine immediately and check whether single-phase motor operates, or bearing damage, coupling axis is not straight and sweep chamber, these will make the machine has abnormal sound, the sound of different fault orientation and bump and sound different, single phase, the whole motor announced regularly and the hum of the strong and the weak;When the bearing is damaged, it will be announced around the bearing accompanied by a thump - thump hum;When the coupling axis is not correct, or the motor slightly sweeps the bore, the entire motor announces a very high hum, accompanied by sharp sharp sharp ears.According to the difference of noise, the fault should be found out and checked item by item. The normal function of the motor should be recovered.

(3) the abnormal noise from reducer announced that reducer on the problems, such as smooth oil, gear reducer or bearing wear or damage, damage to the bearings, etc.), should stop to see at this moment, first determine reducer reducer or bearing is added before using smooth oil, using the substitution of whether smooth oil, such as no smooth by the requirement, the hum of the reducer is not only happen too high, excessive wear or damage to the gear and bearing.Chongqing huugong hoisting machinery is the largest electric hoist supplier in China. It mainly supplies electric hoist of wire rope type and ring chain type.
