Now the elevators are controlled by inverters. When the inverter fails, it will cause inconvenience to many people, and the management personnel will be anxious. If the inverter is maintained at ordinary times, the failure rate of the inverter can be greatly reduced. , Below, China Elevator Lifts Factory introduces how to maintain elevator inverters.
1. The temperature of the elevator electrical room should not be too high, otherwise the inverter components are prone to aging. If air conditioning can be installed, the effect will be quite good.
2. Prevent rainwater from getting wet, usually when a typhoon blows the windows and doors damaged by the wind, so that the inverter is exposed to rainwater. The size and structure of the car are convenient for passengers to enter and exit or load and unload goods. It is customary to regard elevators as the general term for vertical transportation vehicles in buildings regardless of their driving methods.
3. Lightning protection. This is related to the problem of lightning protection facilities for the entire building or the entire community. In general, the inverter struck by lightning is seriously damaged.
4. The cooling fan of the frequency converter should be cleaned regularly, and it should be replaced if it is noisy or not running.
5. The abnormal noise of the elevator motor is usually caused by a problem with the inverter. For example, the three-phase AC current of the motor is unbalanced. At this time, it is best to repair it. When the inverter is completely out of order, the damage may be more serious.
6. If you don’t have any maintenance and repair experience, don’t repair it yourself. You must ask professional maintenance personnel to repair it.
Through the above introduction, Passenger Elevator Factory hopes that you can simply refer to the content of this article in future use.
