The stable operation of industrial doors is inseparable from professional after-sales maintenance, but many enterprises are prone to various misunderstandings in actual operation and maintenance, which not only affects the service life of the door body, but may also cause potential safety hazards. Jiangsu Ambison Internet of Things Technology Co., Ltd. combines years of after-sales experience to take stock of common misunderstandings in industrial door maintenance to help enterprises avoid the "minefield" of operation and maintenance.
Myth 1: Neglect the material maintenance of flexible door body
For flexible doors such as PVC fast doors and soft curtain stacking doors, many companies think that simple cleaning is enough, but this is not the case. The PVC cord of this type of door body is susceptible to damage from acid and alkali substances and sharp objects, and if it is directly wiped with a strong corrosive cleaner, it will accelerate the aging and cracking of the cord. If you do not pay attention to avoidance when passing, sharp goods are easy to scratch the cord and affect the sealing performance. Ambison suggests that the flexible door body needs to be maintained with neutral detergent, and at the same time set up anti-collision warning signs on both sides of the door body to avoid external force damage.
Myth 2: The hard door body only focuses on the appearance and not on the internal components
For hard door bodies such as turbine hard speed doors and aluminum speed doors, enterprises often pay attention to the cleanliness of the surface of the door panel, but ignore the maintenance of internal turbine tracks and balance systems. If the turbine track is not cleaned and lubricated for a long time, there will be stuttering, abnormal noise, and even affecting the opening and closing accuracy of the door body; If the balance spring is not replaced in time after aging, it may cause the door body to fall. Ambison reminds that the rigid door body needs to regularly conduct professional inspection of transmission and balance components, fill with special lubricating oil every six months, and conduct comprehensive performance calibration once a year to eliminate potential faults from the root.
Myth 3: Intelligent systems rely on "automatic" and ignore manual inspections
Industrial doors equipped with intelligent control systems can realize automatic opening and closing and fault warning, but some enterprises rely entirely on automation and abandon manual inspection. In fact, if the surface of the smart sensor is covered with dust, the induction will fail; The line interface may oxidize and loosen in a humid environment, and these problems are difficult to identify by the system in the early stages. Ambison suggests that even intelligent door bodies need to be inspected manually every week, focusing on checking the operating status of induction components and line interfaces to ensure the coordination and stability of the intelligent system and the door body.
Myth 4: Sealing accessories are replaced at will, and adaptability is not paid attention to
After the sealing strips, brushes and other accessories of the door body age, some companies will choose to replace them with general accessories instead of original special parts. However, there are differences in the sealing structure of different models of door bodies, and general accessories cannot achieve precise sealing, which will lead to a decrease in thermal insulation and dustproof performance and increase the energy consumption of the factory. Ambison's original sealing accessories are customized for different door body models, which can perfectly fit the door body structure, and enterprises should give priority to the original accessories when replacing to ensure the core protection performance of the door body.
Myth 5: The emergency device has been idle for a long time and does not do functional testing
The door bodies of special scenarios such as fire garage doors and cold storage insulation lift doors are equipped with manual emergency opening devices, but these devices are often ignored for functional testing due to long-term idleness. In the event of an emergency such as a power outage, the faulty emergency device will directly block the passage, causing production stagnation or emergency delay. Ambison suggests that the door emergency device should be tested once a quarter to ensure that it can be quickly opened and closed manually when the power is cut off, and at the same time carry out emergency operation training for relevant personnel to avoid operational errors in emergencies.
