Electric Winch Maintenance

Electric Winch motor is an important part, but also the most expensive component in the hoist, if damaged, repair or replacement costs will be very high. Therefore, here to remind customers to take good care windlass or electric winch motor. Maintenance is as follows:



1, the use of the environment should be kept dry, the surface of the motor should be kept clean, the air inlet should not be affected by dust, fibers and other obstacles.
 

2, when the motor thermal protection action occurred in succession, the fault should be identified from the motor or overload protection device or setting value is too low, after the fault has been eliminated, it can be put into operation.
 

3, should ensure that the motor well lubricated during operation. General motors run about 5000 hours, which should supplement or replace the grease running found bearing overheating or deterioration of lubricating and hydraulic timely change grease. When replacing the grease, should be cleared of old oil, gasoline and cleaning bearings and bearing cap fuel tank, and then the cavity ZL-3 lithium grease filling between the bearing inner ring 1/2 (2-pole) and 2/3 (for 4,6,8 pole).
 

4, when the end of life of the bearing, vibration and noise motor operation will significantly increase, check the bearing radial clearance reaches the following values, which should replace the bearings.
 

5, when removing the motor from the shaft extension or non-extension end of the rotor can be removed. If there is no need to remove the fan, or remove the rotor from non-drive end is more convenient, when removal of the rotor from the stator, or should prevent damage to the stator winding insulation.
 

6, must write down the primary winding of the form, size and number of turns, wire gauge and other replacement of winding, when the lost data, the manufacturer should be obtained, free to change the original design of the winding, often an electric motor or several performance worse, even unusable.
