During the use of industrial hinges, many unexpected problems can be encountered. And, these problems always come to light at critical times. We need to fix them quickly always, or at least leave the hinge in a barely used condition. When the job is done, then come back to repair the hinge. So how do you repair industrial hinges?
In this article, I will list for you some common problems concerning industrial hinges from a professional’s point of view. And the solutions to these problems.
The most common problem that occurs with hinges is rattling. For this problem, we must first determine whether it is a hinge problem or a door or door frame problem. This should be quickly figured out.
In most cases, it is the hinge that rattles. The door or door frame of the equipment is generally a whole, there will be no rattling problem. It is mainly the connection between the door and the frame that is rubbing or vibrating during the opening or closing of the door. Obviously, the industrial barrel hinges are the connection between the door and the door frame.
After knowing which hinges appear rattling, we can first add some anti-rust oil or lubricant. Usually, the problem can be solved quickly after this treatment. If the problem remains, then see if there is serious friction between the hinge blocks. There may be some slight deformation of the hinges, causing friction between the hinge blocks.
If this is the problem, you need to check if the screws have loosened. Retighten each screw once.
The door does not close tightly
The phenomenon that the door does not close tightly may be due to the installation of hinges when the gap between the door and the door frame is set aside too small, resulting in the door and the door frame squeezing each other when the door is closed. Another situation is that after a long time, the screws on the industrial hinges have loosened. This time only re-tighten the screws to solve the problem.
The latter situation occurs more often. Because the newly installed door will generally do a check, will not happen just installed door closed tight phenomenon. In addition, if we use industrial hinges, not enough load-bearing will also appear as a problem.
Load-bearing is not only considered to meet the door load-bearing requirements. It is also necessary to consider its long-time load-bearing state. After a long time, the hinge will become fatigued, resulting in the deformation of the hinge block, which will lead to the situation that the door does not close tightly.
Therefore, when buying industrial hinges, make sure that they have sufficient load-bearing performance.
The door won’t open
It is possible that the door will not open because the hinges have been deformed. The hinge core cannot continue to rotate, causing the door to fail to open or close. When this happens it is best to replace the hinges with new ones. Re-do an inspection of the door to see if the door itself is also deformed.
Door sags down
Most of the reasons for door sagging are also due to fatigue of the hinges over a long period of time. So that the hinge block deformation occurs vertically downward so that the door will appear sagging phenomenon.
Especially when the door width is relatively wide, and the height is a relatively small case. At this time, the door is equivalent to a lever, and the hinge becomes the fulcrum of the lever. If the hinges do not have sufficient weight-bearing performance, it is easy to occur this sagging phenomenon.
The solution is to replace the hinges with stronger load-bearing hinges. If the door is newly designed, then consider the door’s aspect ratio. Doors that are too wide and too short are prone to this phenomenon.
It is rare for hinges to break. We will inform our customers in advance of the size of the hinge’s load-bearing capacity when they purchase the hinge. This prevents customers from exceeding their limits during use, which can lead to hinge breakage.
Hinges made of zinc alloy are prone to fracture. This is mainly because it exceeds its load-bearing range. Or forces in other directions are generated during the opening and closing of the door, causing the industrial hinge to break.
This situation is a serious production accident and must be dealt with seriously. Broken hinges mean that the door can fall and even hit a worker’s foot. For special heavy industrial equipment doors, be sure to ensure the strength and load-bearing properties of the hinges. For heavy equipment doors, it is best to use industrial heavy-duty hinges for safety reasons.
This is an introduction to repairing industrial hinges. Different treatment methods are used for different problems. If there are still questions, you can contact us for consultation.
