Installation operation of DEMAG motor ZBA ZNA 71 B4
DEMAG develops robust and reliable industrial cranes, crane components and drive technology to provide customers with a portfolio of intelligent solutions for logistics and logistics. It all started in 1819 with the partnership of the Harcourt Maschinenbaut (Mechanische Werkst tte Harkort & Co.).) was founded in Wetter an der Ruhr.
The procedure for using the DEMAG motor ZBA ZNA 71 B4 is as follows:
1. Preparation before operation.
Check the nameplate and appearance of the motor, confirm that the motor model, voltage, frequency and rated parameters and other information are consistent with the requirements, and there is no obvious damage and abnormality in the appearance.
Check that the motor accessories (such as cooling fans, encoders, brakes, etc.) are complete and installed correctly.
Check whether the power supply line is well connected, and there is no short circuit or open circuit.
Check that the required lubricant for the motor is added to the position, as a general rule, the newly purchased motor has been filled with the right amount of lubricant before leaving the factory.
Prepare the tools and instruments needed for the operation, such as screwdrivers, wrenches, multimeters, etc.
2. Check before power-on.
Confirm that the power supply voltage is consistent with the rated voltage on the motor nameplate, and whether the frequency meets the requirements of the motor.
Use a multimeter to check whether the resistance value of the stator coil of the motor is within the normal range.
Check whether the motor housing is well grounded to avoid electric shock accidents.
Manually turn the car to check whether the motor rotates flexibly and whether there is any jamming.
3. Power-on test.
Close the power switch and start the power-on test.
Observe whether the starting current and running current of the motor are normal, and check if there is any abnormality.
Listen to the sound of the motor running, and the normal operation of the motor should have no abnormal sound. If there is an abnormal sound, it should be stopped immediately for inspection.
Test whether the speed and torque of the motor meet the requirements, if the speed or torque is found to be insufficient, check whether the load of the motor is too heavy or the power supply voltage is too low.
During the power-on process, pay attention to observe the temperature change of the motor to ensure that the motor will not be damaged by overheating.
When the test is over, disconnect the power switch.
Fourth, the operation steps precautions.
During operation, the rated parameters (such as voltage, frequency, current, etc.) on the motor nameplate should be strictly observed, and no overload or overspeed operation should be allowed.
Before starting the motor, it is important to ensure that the power supply is turned on and there is no short circuit.
When starting the motor, you should manually turn the car first, confirm that there is no jamming phenomenon and then start with power.
During operation, if there is an abnormal situation (such as overload, phase failure, short circuit, etc.), it should be stopped immediately for inspection.
In the event of a shutdown, the power switch should be cut off before subsequent maintenance operations are carried out.
When carrying out maintenance, be sure to cut off the power supply and take safety precautions to avoid electric shock accidents.
If it is necessary to shut down for a long time, the inside of the motor should be cleaned and coated with an appropriate amount of lubricant, and then properly placed in a dry and ventilated place.
During use, the fasteners of the motor should be checked regularly to see if they are loose or falling off, and if there is any abnormality, it should be dealt with in time.
When replacing parts or repairing, be sure to follow the repair manual of the DEMAG motor or contact a professional technician for operation.
