Stainless steel fireproof rolling shutter door

Stainless steel fireproof rolling shutter doorThe maintenance techniques for pneumatic fireproof rolling shutter doors are as follows：

1. Stainless steel fireproof rolling shutter doorDaily appearance and condition inspectionCheck the curtain surface for damage, deformation, and rust every week, and check for debris blocking the guide rails and rollers; Ensure that the roller blind is in a normal closed or folded state, without any obstructions such as obstruction or binding; Test the manual zipper or joystick to ensure smooth opening and closing without any jamming, and the curtain surface runs smoothly without tilting; Check smoke/temperature detectors and control boxes Reminder: The wiring terminals are securely fastened.

5. Regular maintenance of mechanical componentsClean the guide rail, scroll, and gearbox every month to remove dust, oil stains, and foreign objects; Add lubricating oil to rotating parts such as transmission chains, pulleys, and bearings to prevent oil contamination of the curtain surface; Check the connecting bolts and rivets on the curtain surface, tighten them promptly if they are loose, and repair or replace any damaged areas.

6. Regular inspection of electrical systemTest the electric opening and closing function every month to ensure smooth start stop, accurate limit, and no abnormal noise; Check the power supply and circuit insulation of the control box, and ensure that the backup power supply (such as battery) can switch normally; Quarterly linkage testing is conducted to trigger smoke/temperature detectors, and the roller shutter needs to operate according to the design logic (such as two-step descent) with normal feedback signals.

7. Annual comprehensive inspection and maintenanceVerify the fire resistance limit certificate of the curtain surface annually, and if necessary, entrust a third party to conduct testing; Check the gaps between the curtain surface and the guide rail, ground, and wall, and replace the sealing strip when it ages; Continuously open and close the roller shutter 5 times, verify the mechanical strength and electrical reliability, and record the operating parameters; Keep maintenance records, including inspection results, maintenance content, and fault handling.

8. Environmental adaptability maintenanceStrengthen rust prevention treatment in humid environments, and avoid contact with sharp objects on the inorganic fiber curtain surface; When there is a malfunction (such as jamming or inability to link), immediately stop using and report for repair, and take temporary fire isolation measures during this period.
