High speed doors can cause minor problems due to the high frequency of opening and closing of daily work. So, what are the maintenance methods of the quick roll curtain door?
Regular inspection of the rapid curtain door can be prevented before it happens, because the composition structure of the fast curtain door is not complicated, through the naked eye to see the general situation of the product, mainly to observe whether the door body lifting and closing smoothly.
If the quick shutter door is not used for a long time to run regularly, test whether the open and close button is correct, the electrical control box indicates signal condition, etc.
More detailed can be divided into inverter maintenance, motor maintenance, regular inspection of whether there is foreign material blocking the inverter air infest, every month to clean the filter cooling airfring dust.
Annual inspection: conductors and insulators have no corrosion, if any, should be promptly wiped with alcohol. Then check the bolts, screws and plug-in is not loose is the case, the output input resistor ground and phase resistance there is no short circuit, the normal situation should be greater than dozens of mega euros.
Test the smoothness of each circuit voltage output for the open-close power supply of the quick roll door. Contactor contacts have no signs of fire, in serious cases to replace the new contactor.
Confirm the correctness of the control voltage, perform a sequential protection action test, confirm that the protection display circuit is free of anomalies, and confirm the balance of the output voltage when the drive is running alone.
DESEO high speed door motor maintenance process:
Cleaning the fixed roist -- replacing the carbon brush or other components -- vacuum F-grade pressure immersion paint -- drying -- correcting balance.
