Guide About Maintenance For Automatic Revolving Door
The automatic revolving doors are well installed in the modern buildings like the hotels, shopping malls, airports, public buildings etc., it's much common for us to see the revolving doors in the buildings listed above . As a combination of mechanical parts and electrical parts, it is not surprising that some problems appeared, that's what we will talk about here, the maintenance for the automatic revolving door .
Importance of Maintenance for Automatic Revolving Door
▪ Comply with Regulations. Automatic revolving door must comply with accessibility and safety regulations locally and preventative maintenance ensures our doors could meet these standards, avoiding potential fines or legal issues.
▪ Ensure Safety. Automatic revolving doors' malfunctions may bring safety risks to the users, may cause injury to the users, and regular inspections and maintenance could help us to identify and rectify potential dangers.
▪ Enhance Performance. Periodic maintenance could ensure smooth and efficient operation of the revolving door.
▪ Extend Service Life . Maintain the system in a timely manner before it becomes unusable could extend the service life of the automatic revolving door, delay the need for costly parts' replacement.
▪ Motor and Gearbox . From SIEMENS, 250W, the strength of SEW Gear Units is their simple mechanical structure. This yields a higher efficiency than pure worm gear units, in addition, the S series gear units are quiet during operation.
▪ Main Control Unit. 1st class system in the world, SIEMENS , the model we used have the powerful intelligent I/O "positioning" module that was developed specially for the smartest programmable controller.
▪ Inverter. From Germany, AC Inverter for 0.25kW (0.33HP) 220V 3 Ph motor. Converts fixed frequency single phase 220V input to variable frequency three phase 220V to control the speed of a standard AC Induction motor.
▪ Encoder. The Encoder we used for our revolving door delivers outstanding performance in mechanical shock-resistance and is capable of withstanding higher axial and radial loads so as to meet various industrial environments.
▪ Emergency Stop Button. To stop movement of the automatic door under any circumstance, ensuring safety of the passersby in case of emergency.
▪ Handicap Button. The door will revolve with a slower speed for a round, after that, the door revolves normally.
Tips and Suggestions
▪ Regular Cleaning . Clean the door surfaces and canopy inside, to remove dirt, dust, and debris that may affect revolving doors' performance.
▪ Lubrication. Apply lubricant to the frequently operated components, like motor, gearbox, main wheels, belts, to reduce friction and wear, ensure the revolving doors' smooth operation .
▪ Sensor Inspection and Calibration. Check the alignment & sensitivity of the sensors/radars . Clean the lenses to ensure they are free from obstructions. If needed, calibrate the sensors to ensure accurate detection.
▪ Spare parts replacement ahead. To the important parts like sensors, we have to check them carefully, if they are in bad condition, strongly suggest to replace them before they are damaged, to avoid the accident maybe caused by them to make people badly collision or pinch .
