With the development of industrial automation, frequency converters are more and more widely used in the industrial field, and maintenance is more and more important. With the development of industrial automation, frequency converters are more and more widely used in industrial fields, and maintenance is more and more important . Now let’s talk about the daily maintenance of the inverter.
Matters needing attention when the inverter is working normally:
1. Check whether the motor has abnormal sound and vibration.
2. Whether the inverter and motor are abnormally heated.
3. Whether the ambient temperature is too high.
4. Whether the load ammeter is the same as usual.
Whether the cooling fan of the inverter is running normally
Maintenance requirements in the day-to-day operation of the frequency converter
1. Check whether the cooling system is normal, and clean the dust of the air filter.
2. Check whether the screws, bolts and other fasteners of the inverter are loose, and perform necessary tightening; for the parts with soldering and crimping terminals, check whether there is corrosion, discoloration, cracks, damage, etc., and also check the frame Whether the structural parts are loose, whether the conductors and wires are damaged, etc.
3. Check whether the connection of the control circuit board is loose, whether the capacitor is leaking, whether the lines on the board are rusted, broken, etc.
4. Check whether the filter capacitor is leaking and whether the capacitance is reduced.
- Check whether the insulation resistance is within the normal range.
Note:
1.The daily maintenance and repair of the inverter must be carried out in accordance with the product manual.
2.Periodic inspections are recommended and should be performed once a year.
3.Replacing the aging components produced by the inverter during operation
