As an important part of the door control system, the door closed device does need regular maintenance to ensure its normal work and extend its service life. Here are some important information about the maintenance of door closers:
Maintenance necessity
In the process of use, due to the frequent opening and closing of the door and the influence of environmental factors, its internal mechanical components will gradually wear out, and the hydraulic oil will gradually deteriorate. If regular maintenance is not carried out, it may lead to problems such as reduced function of the door close device, insufficient closing force, poor buffer effect, and even oil leakage, which will affect the normal use and safety of the door.
Maintenance period and contents
Maintenance cycle:
In general, door closers should be lubricated every 6 months to maintain the smooth operation of their internal mechanical components and reduce wear. For places that are used more frequently, such as shopping malls, hospitals, etc., more frequent maintenance may be required.
Maintenance contents:
Check and tighten: Check all screws and re-tighten the newly installed door close to ensure that the installation is stable and not loose at the beginning of use (such as within a week to ten days). After that, regular inspections and necessary adjustments or reinforcement should also be carried out.
Cleaning and drying: Thoroughly clean and dry the surface of the closing mechanism of the door closer to prevent dust and debris from affecting the normal operation of the door closer.
Lubrication maintenance: Add the right amount of lubricating oil to the bearing, gear and other rotating parts to reduce friction and improve efficiency. For electric door closers, it is also necessary to pay attention to the use of hydraulic oil recommended by the manufacturer for maintenance, and the use of low freezing point hydraulic oil in cold areas to prevent freezing from affecting performance. At the same time, the electric door closers need to be filled with antifreeze oil every year to maintain their normal operation.
Check the buffer effect: test whether the buffer effect of the door closed device is good, to avoid the impact between the door and the door frame resulting in the deformation of the door body. If the buffer effect is found to be poor, adjust or replace the related components inside the door close device in time.
Maintenance precautions
When maintaining the door close, turn off the power or ensure that the door close is in a non-working state to avoid accidents.
Use appropriate tools and lubricants for maintenance operations to avoid unnecessary damage to door closers.
If the door close is found to be seriously damaged or faulty, contact professionals in time for repair or replacement.
Importance of maintenance
Regular maintenance of door closers can ensure their normal operation and extend their service life, and improve the convenience and safety of the use of doors. At the same time, the maintenance can also reduce the repair and replacement costs caused by the failure of the door closure device, saving money for users.
To sum up, door closers do need regular maintenance. Users should develop a reasonable maintenance plan according to the frequency of use and environmental conditions of the door close, and perform operations according to the maintenance period and content to ensure the long-term stable operation of the door close.
