The daily maintenance of automatic lifting transfer Windows not only requires following the standard procedures but also paying attention to some key details to avoid equipment damage or affecting the clean environment due to improper operation. The following are the core points to note in daily maintenance:
I. Taboos of Cleaning and Maintenance
Avoid using corrosive cleaning agents
It is strictly prohibited to wipe the surface of the equipment, sealing strips, or lifting tracks with corrosive solutions such as alcohol (concentration > 75%), strong acids, or strong alkalis. Otherwise, it will cause aging of plastic/metal parts, cracking of sealing strips, and damage to the sealing performance and appearance of the equipment.
When cleaning the filter, do not rinse or soak it with water to prevent the filter material from becoming ineffective. Only compressed air can be used to blow away surface dust (for non-high-efficiency filters), or the filter can be replaced directly.
Prevent moisture from entering key components.
When cleaning, avoid water flowing into electrical control boxes, motors, sensors, and other electrical components to prevent short circuits or leakage. If water splashes accidentally, power should be cut off immediately and the area dried. Only after confirming that it is completely dry should power be restored.
After cleaning the lifting track, it must be thoroughly dried. Residual moisture may cause the track to rust or the lubrication to fail.
Ii. Key Details of Mechanical and Electrical System Maintenance
The particularity of the maintenance of lifting mechanisms
When lubricating transmission components (chains, gears), food-grade or cleanroom-specific lubricants (such as silicon-based grease) must be used. The use of ordinary industrial lubricating oil is strictly prohibited to prevent volatile substances from contaminating the clean area or generating odors.
If abnormal noises occur during the lifting process, do not disassemble the motor or transmission box by yourself. First, check for foreign objects on the track. If there are still abnormalities after the foreign objects are removed, contact professional personnel for maintenance (to avoid damaging precision components due to improper operation).
Strict requirements for electrical safety
When inspecting the electrical system, it is essential to operate with the power off. It is strictly forbidden to plug in or unplug plugs or touch the internal terminal blocks while the power is on. Especially in a humid environment, insulating gloves must be worn.
When the interlock device malfunctions, it is strictly forbidden to short-circuit the interlock circuit and force its use. Otherwise, it will cause a direct connection between the clean area and the non-clean area, damaging the clean environment. It must be thoroughly repaired before being put back into use.
Iii. Key Points for Sealing and Cleanliness Protection
Maintenance taboos for sealing strips
When replacing the sealing strip, it is necessary to select a food-grade or medical-grade silicone strip that matches the original model. Do not use ordinary rubber strips as substitutes (as they may release contaminants or have insufficient temperature resistance).
When cleaning the sealing strip, avoid scratching it with a hard-bristled brush or sharp objects to prevent surface damage that could lead to seal failure.
Specifications for filter replacement
When replacing the high-efficiency filter, the operation must be carried out in a clean environment. Avoid touching the filter paper with your hands (clean gloves must be worn), and ensure that the frame is tightly sealed during installation to prevent air leakage.
Waste filters should be treated as hazardous waste (if used in medical or biological laboratories) and must not be discarded at will.
Iv. Precautions for Operation and Emergency Response
Load and item delivery restrictions
It is strictly prohibited to transfer liquids, easily spilled powders, or sharp objects (unless the seal is intact) to prevent contamination of the internal cavity, corrosion of components, or scratching of the track.
Even if the items are not overloaded, heavy objects should not be left idle on the lifting platform for a long time (especially when not in operation) to prevent the lifting mechanism from deforming due to long-term force.
The correct way of emergency operation
When manually resetting the emergency device, operate slowly and do not apply excessive force to prevent damage to the gears or chains. After resetting, it is necessary to check whether the lifting platform is level to avoid subsequent operation jamming.
If the equipment experiences dangerous situations such as leakage or sparks, the main power supply should be immediately cut off instead of merely turning off the equipment switch. Professional electricians should be contacted for maintenance, and non-professionals are strictly prohibited from inspecting the circuit.
V. Record and Traceability Management
Establish a maintenance ledger to record in detail the cleaning time, filter replacement date, fault handling situation, etc., which is convenient for tracing the equipment status and promptly identifying periodic problems (for example, frequent failures of a certain component may require upgrading or model replacement).
Maintenance personnel need to be trained, familiar with the structure of the equipment, and the management norms of the clean area, to avoid secondary pollution during the maintenance process due to unskilled operation.
By following the above precautions, human errors can be reduced during the maintenance process, which not only ensures the long-term stable operation of the equipment but also protects the integrity of the clean environment to the greatest extent. For faults beyond the scope of daily maintenance (such as motor burnout or damage to the circuit mainboard), it is essential to contact the original equipment manufacturer or authorized service provider for handling to avoid greater losses caused by non-professional maintenance.
