Daily use and maintenance methods of airport lifting doors and aircraft warehouse doors

Daily maintenance methods for airport lifting doors and aircraft warehouse doors

Recently, Kunming Haydun Automatic Doors repaired and maintained a batch of lift doors and aircraft hangar doors at the airport, and summarized a set of daily use and maintenance methods for hangar doors. This method is essential for ensuring that lift doors and hangar doors Product performance, extended service life and safe use of doors are crucial.

1. Door surface cleaning

Clean regularly. It is recommended to perform routine cleaning of the door surface at least once a month. If the hangar door is in an environmentIn areas that are prone to pollution such as dust, wind and sand, or near the seaside, the cleaning frequency can be increased appropriately, such as once every 2-3 weeks.

Cleaning tools and material selection. For cleaning the surface of the door body, you should use a soft rag or cleaning sponge to avoid using rough cleaning tools to scratch the surface coating of the door body. You can choose the appropriate cleaner according to the door material. For example, for metal doors, you can use a mild metal cleaner; for doors with special coatings, you need to use a matching special cleaner to ensure that there is no Damage coating.

Cleaning steps. First, gently wipe the door surface with a dry rag or cleaning sponge to remove floating dust and loose stains. Then, apply an appropriate amount of detergent on a rag or cleaning sponge, and gently wipe it in the direction of the door\’s texture, focusing on cleaning areas with obvious stains. After wiping, use a clean wet rag to wipe away the detergent residue, and finally use a dry rag to dry the door surface to prevent water stains from causing rust or corrosion.

2. Guide rail and pulley maintenance

The guide rails and pulleys should be inspected once a month to check their operating status and wear. During periods of frequent use of the hangar door (such as airport flight peak periods, etc.), the number of inspections can be appropriately increased to once every half a month.

BiFor example, check whether the surface of the guide rail is flat and smooth, and whether there are obvious pits, bulges, scratches or rust. If the surface of the guide rail is found to be uneven, it may affect the smooth operation of the pulley, causing the door to not open and close smoothly. At the same time, check whether the installation of the guide rail is firm and whether the connecting bolts are loose.

Observe the appearance of the pulley to see if there is wear, deformation, cracks, etc. The wear of the pulley will reduce its rolling efficiency and affect the opening and closing speed and smoothness of the door. It is also necessary to check whether the rotation of the pulley is flexible. You can manually turn the pulley and feel whether the rotation resistance is normal. If the rotation is difficult, the internal bearing of the pulley may be damaged or there may be foreign matter blocking it.

If you find slight scratches or rust on the surface of the guide rail, you can first lightly polish it smooth with sandpaper, and then apply an appropriate amount of anti-rust oil for protection. If the guide rail installation bolts are loose, appropriate tools should be used to tighten them in time to ensure that the guide rail is installed firmly.

When the pulleys appear to be worn, deformed, etc., they should be replaced with new ones in time. If the pulley rotates inflexibly due to foreign matter blocking, the foreign matter can be carefully cleaned; if the bearing is damaged, the bearing or the entire pulley assembly needs to be replaced.

3. Hinge and hinge maintenance

Inspections are also carried out once a month, focusing on areas where doors are frequently opened and closed (such as hangar doors).hinges and hinges at the main entrance and exit locations).

Check the appearance of hinges and hinges and check for deformation, cracks, wear, etc. Deformed or severely worn hinges and hinges may cause inaccurate door opening and closing angles and even affect the structural stability of the door.

Check the connection between the hinge and the hinge to see if the bolts are loose and make sure they are firmly connected. Loose bolts may cause the hinges and hinges to make abnormal noises when the door is opened and closed, and may even cause parts to fall off, endangering the safety of the door.

Hinges and hinges that are deformed, cracked or severely worn should be replaced with new parts in time. If the connecting bolts are found to be loose, appropriate tools should be used to tighten them immediately to restore the firmness of the connection.

4. Motor system inspection

A comprehensive inspection of the hangar door\’s motor system should be conducted every quarter, including wires, plugs, switches, controllers, motors and other components.

Check whether the wireThere are conditions such as damage, aging, and peeling of the outer skin. Damage or aging of the wires may cause leakage and endanger personal safety. At the same time, check whether the connection of the wires is firm and whether there are loose connections or false connections. Loose connections may cause circuit interruption or instability, affecting the normal operation of the door.

Check whether the plug is plugged in tightly and whether there is any burning, deformation, etc.; whether the switch can operate normally and whether its functions are intact, such as whether the functions such as opening, closing, and pausing are realized normally.

Check whether the controller\’s display screen (if any) is displayed normally and whether various settings can be adjusted normally; check whether the running sound of the motor is normal, whether there is any abnormal vibration, whether the temperature of the motor is within the normal range and whether it is too high The temperature may indicate a motor failure or overload operation.

If the wires are found to be damaged, aged, etc., they should be replaced with new ones in time. For loose connections, use appropriate tools to tighten them to ensure the wires are securely connected.

Plug and switch: If the plug is burnt or deformed, the plug should be replaced with a new one; if the switch function is abnormal, its internal structure should be checked. If damaged parts are found, the corresponding parts should be replaced to restore the function of the switch. normal function.

When the controller display is abnormal or the settings cannot be adjusted normally, the controller may need to be repaired or replaced; if the motor has abnormal sound, excessive vibration orIf the temperature is too high, stop using the door and contact professional maintenance personnel to check and repair the motor.

5. Sealing strip inspection

Inspect the sealing strip every six months to check its sealing effect and aging. Check whether the sealing strip is complete and whether it is damaged, torn or peeled off. Damaged sealing strips will reduce the sealing performance of the door body and affect the thermal insulation, heat insulation, sound insulation and other effects in the hangar.

Observe the elasticity of the sealing strip to see if it can still fit the door body and door frame tightly. Insufficient elasticity may mean that the strip has begun to age, which will also affect the sealing effect. When the sealing strip is found to be damaged, torn, or fallen off, it should be replaced with a new one in time. Aged sealing strips should also be replaced to ensure good sealing performance of the door body.

6. Lubrication and maintenance

Some key parts of the hangar door need to be lubricated regularly, such as guide rails and pulleys, hinges and hinges, motor bearings, etc. The frequency of lubrication is generally once per quarter, but if the hangar door is used frequently, the frequency of lubrication can be appropriately increased to once every two months.

Lubricating materials suitable for the materials of each part and the operating environment should be selected. For example, for metal parts, high-quality General metal grease; for high-precision components such as motor bearings, special bearing grease can be used to ensure good lubrication and protection of components.

For the guide rails and pulleys, first clean off the old grease (you can use a clean rag with a small amount of detergent to wipe it), and then apply an appropriate amount evenly on the guide rail surface and the rolling parts of the pulleys of grease.

For hinges and hinges, apply grease to the connecting parts and rotating parts of the hinges and hinges to ensure smooth rotation.

For motor bearings, according to the motor instruction manual, accurately apply an appropriate amount of grease to the bearing area. Be careful not to apply too much to avoid causing motor failure.
