What common faults of aluminum rolling shutter doors need to be prevented?

Introduction
During the hot summer, aluminum rolling shutter doors are an ideal choice for many commercial and residential buildings due to their lightness, durability and good insulation. However, like all mechanical devices, aluminum rolling shutter doors may also have some common faults that affect their normal operation and service life. This article will take a deep look at the common faults of aluminum rolling shutter doors and their preventive measures to help you keep your rolling shutter doors in good operating condition during the summer.

1. Common faults and preventive measures of aluminum rolling shutter doors

1.1 Mechanical faults

1.1.1 Guide rail faults
The guide rail is one of the key components for the operation of rolling shutter doors. Common guide rail faults include friction strip wear, guide rail deformation or blockage. Friction strip wear can cause the rolling shutter door to make noise or jam during operation, while guide rail deformation or blockage may cause the rolling shutter door to fail to open or close smoothly.
Preventive measures:
Check the condition of the guide rail regularly to ensure that the friction strip is intact. If the friction strip is found to be worn, it should be replaced in time.
Clean the debris and dust inside the guide rail to ensure that the inside of the guide rail is clean and smooth.
Check the guide rail for signs of deformation and repair or replace it if necessary.
1.1.2 Roller failure
The roller is responsible for rolling up and lowering the curtain plate. Common roller failures include rust on the roller, loose roller or broken spring sheet inside the roller. These problems may cause the rolling door to fail to open or close normally, and even the risk of the curtain plate falling off.
Preventive measures:
Regularly check the operation of the roller to ensure that it is smooth and unobstructed. If the roller is found to be rusty, it should be rust-proofed in time.
Check the fixing screws of the roller to ensure that it is tightened and not loose.
For rollers with spring sheets, check the status of the spring sheets regularly. If they are broken or fall off, they should be replaced or repaired in time.
1.1.3 Curtain plate failure
The curtain plate is the main component of the rolling door. Common curtain plate failures include deformation, breakage or loose connection parts of the curtain plate. These problems will affect the overall appearance and use function of the rolling door.
Preventive measures:
Check the integrity of the curtain plate regularly to ensure that there is no obvious deformation or damage.
Check the connecting parts of the curtain plate, such as rivets and fixing strips. If they are loose or fall off, they should be repaired in time.
For deformed curtain plates, they can be recalibrated or replaced.

1.2 Electrical failure
1.2.1 Motor failure
The motor is the core component of the electric rolling door. Common motor failures include motor motionlessness, slow speed, motor overheating or abnormal noise. These problems may be caused by circuit breakage, motor burnout, excessive load, etc.
Preventive measures:
Check the operation of the motor regularly to ensure that it is working properly. If the motor is found to be abnormal, it should be repaired or replaced in time.
Check the power supply line of the motor to ensure that the connection is firm and there is no open circuit or short circuit.
Avoid running the motor under overload for a long time to extend its service life.
1.2.2 Control system failure
The control system is responsible for the opening and closing operations of the rolling door. Common control system failures include control failure, button failure, inaccurate limit switch action, etc. These problems may cause the rolling door to fail to respond to operating instructions normally.
Preventive measures:
Regularly check the various components of the control system, such as relays, micro switches, limiters, etc., to ensure that they are working properly.
Clean the control panel and buttons to ensure that there is no dust or debris that affects their function.
Check the position and sensitivity of the limit switch to ensure that it can accurately control the operating range of the rolling door.

1.3 Failures caused by environmental factors
1.3.1 Influence of bad weather
In summer, bad weather such as high temperature, heavy rain and strong wind may affect the rolling door. High temperature may cause the rolling door material to expand and affect its sealing performance; heavy rain may cause water to enter the rolling door and damage the motor and electrical system; strong wind may cause the rolling door to deform or damage.
Preventive measures:
When designing and installing the rolling door, consider adding protective devices such as waterproof and windproof to improve its ability to adapt to bad climates.
Regularly check the sealing performance of the rolling door to ensure that it can still maintain a good sealing effect in bad weather.
Before the arrival of heavy rain or strong winds, conduct a comprehensive inspection of the rolling door to ensure that it is in good condition.
1.3.2 Dust and dirt accumulation
There is a lot of dust and dirt in the air in summer, which is easy to accumulate on the surface of the rolling door and in the guide rails. This may cause the rolling door to run unsmoothly or even damage the components.
Preventive measures:
Clean the surface and guide rails of the rolling door regularly, and use a soft rag or vacuum cleaner to remove dust and dirt.
Avoid using hard objects or chemical cleaners to avoid scratching or corroding the surface of the rolling door.

2. Maintenance Guide for Aluminum Rolling Doors
2.1 Daily Inspection and Cleaning
Regular daily inspection and cleaning are the basis for keeping the rolling door running well. The inspection content includes whether the door rails and door leaves are deformed or blocked, whether the manual button is locked well, and whether the indicator signal of the electric control box is normal. When cleaning, focus on removing dust and dirt on the surface of the door panels and guide rails.
2.2 Regular lubrication
Regular lubrication of the operating parts of the rolling door can reduce friction, reduce noise and improve operating efficiency. Use suitable lubricants and apply them to the guide rails, pulleys, bearings and other parts to ensure smooth operation.
2.3 Check the electrical system
Regularly check the electrical system of the rolling door, including cables, terminals and control panels. Make sure all electrical connections are safe and there are no exposed or damaged wires. If any abnormality is found, contact a professional for repair in time.
2.4 Adjust spring tension
For rolling doors with springs, regularly check whether the spring tension is appropriate. Excessive or insufficient spring tension will affect the opening and closing effect of the rolling door, and even cause safety hazards. If necessary, adjust the spring tension in time.
2.5 Clean the door edge seal
Check whether the door edge seal is intact. If it is damaged or aged, replace it in time. The function of the seal is not only to prevent water and dust, but also to reduce noise and keep the indoor temperature stable.

3. Conclusion
Aluminum rolling doors provide good insulation and protection for buildings in the summer. Regular inspection, cleaning, lubrication and maintenance can effectively prevent common mechanical and electrical failures and extend the service life of rolling doors. At the same time, pay attention to the impact of environmental factors on rolling doors and take appropriate protective measures to ensure that they can operate normally in all weather conditions. Follow these maintenance guidelines, and your aluminum rolling doors will continue to perform at their best in the summer, providing reliable protection for your commercial and residential spaces.
