Stainless steel pneumatic fireproof rolling shutter door

miningStainless steel pneumatic fireproof rolling shutter doorIt is a fire separation facility designed specifically for mine environments, combining the durability of stainless steel, the safety of pneumatic systems, and the thermal insulation performance of fire-resistant rolling shutters. It is suitable for fire separation needs at large mine openings.The following is a detailed introduction to its characteristics, advantages, and maintenance points:

1、 Characteristics and advantages

1. Material advantage：

4. 

• stainless steel materialIt has the characteristics of high strength, corrosion resistance, and rust prevention, and can be used for a long time in harsh mining environments such as humidity, acidity, and alkalinity, significantly extending its service life.

• structurally stableThe door body is composed of multi joint movable door panels connected in series, which rotate up and down around a scroll in a fixed slide. The structure is compact and tightly closed, effectively preventing illegal intrusion and providing good anti-theft performance.

5. Pneumatic system safety：

• Explosion-proof designUsing compressed air as a power source,Stainless steel pneumatic fireproof rolling shutter doorAvoiding the possibility of electrical sparks generated by electrical components, fundamentally eliminating the risk of gas and coal dust explosions, and adapting to the flammable and explosive environment of mines.

• Emergency operationEquipped with mechanical emergency operation devices (such as manual zippers or joysticks) to ensure that the door can still be manually controlled to open and close in the event of power failure or pneumatic system failure.

6. fire prevention ：

• High fire resistance limitCompliant with the fire integrity requirements of fire-resistant rolling shutters, it can effectively block the spread of flames and high-temperature smoke for a certain period of time, saving valuable time for personnel evacuation and firefighting rescue.

• Good sealing performanceAn effective seal is formed between the door body, guide rail, and ground to prevent smoke leakage and enhance the fire partition effect.

7. Flexible and convenient operation：

• Electric/manual dual mode: Supports electric opening and closing as well as manual operation. The electric roller shutter can be equipped with intelligent devices such as remote control and induction switches to achieve remote control, automatic switching, and other functions.

• Smooth opening and closingThe curtain surface runs smoothly inside the guide rail without derailment or obvious tilting, ensuring safe use.

8. save space：

• Scroll style designThe door body is folded upwards in the form of a scroll, occupying minimal space, making it particularly suitable for places with high space utilization requirements such as mine tunnels, garages, and warehouses.

2、 Maintenance points

1. routine inspection：

• Visual inspectionCheck the curtain surface for damage, deformation, and rust every week, and check for debris blocking the guide rails and rollers.

• status checkEnsure that the roller blind is in a normal closed or folded state, without any obstructions such as obstruction or binding.

• Manual operation inspectionTest the manual zipper or joystick to ensure smooth opening and closing without any jamming.

• Electrical system inspectionCheck the control box Reminder: The wiring terminals are securely fastened.

2. regular maintenance：

• Cleaning and maintenanceClean the guide rail, scroll, and gearbox every month to remove dust, oil stains, and foreign objects; The surface of stainless steel material is flat and smooth, easy to clean and maintain. Daily cleaning only requires simple wiping to keep it as smooth as new.

• Lubrication and maintenanceAdd lubricating oil to rotating parts such as transmission chains, pulleys, and bearings to avoid oil contamination on the curtain surface.

• Tightening inspectionCheck the connecting bolts and rivets of the curtain surface, tighten them promptly if they are loose, and repair or replace any damaged areas.

3. Annual testing：

• Fire resistance performance testingVerify the fire resistance limit certificate of the curtain surface annually, and if necessary, commission a third-party testing agency to conduct random inspections.

• Linkage function testConduct a linkage test, trigger the smoke/temperature detector, and the rolling shutter should operate according to the design logic (such as two-step descent), with normal feedback signals.

• Mechanical strength testingContinuously open and close the roller shutter 5 times, verify the mechanical strength and electrical reliability, and record the operating parameters.

4. Environmental adaptability maintenance：

• rust prevention treatmentStrengthen rust prevention treatment in humid environments to ensure that stainless steel materials are not corroded.

• Avoid collisionsPrevent sharp objects from hitting the curtain surface to avoid damaging the fireproof material.

5. Fault handling：

• Report for repair in timeWhen a malfunction is detected (such as jamming or inability to link), immediately stop using it and report it for repair. During this period, temporary fire isolation measures will be taken.

• Record maintenanceKeep maintenance records, including inspection results, maintenance content, fault handling situation, etc., for traceability and inquiry.
