Today, the repair of the door closer is handled by each other, the main thing is to study some details. The main function of the door closer is to automatically slam the door, it gives the opportunity to a person not to close it, because it closes. In order for the device to work properly for a long time, you must configure it correctly.
Adjust the door closer.
Highlights
If there is a constant problem of open doors, it can be easily solved by installing the closer. After installing such an appliance, it will be automatically closed, it does not need to make any effort. Such devices are often installed in stores, offices and other commercial institutions. But there are cases of domestic use. Especially if a heavy metal entrance door is installed.
Design door closer.
Thanks to such devices, it will close smoothly and quietly. There are models that can fix it in the open position, such a function is called HOLD. In this case, you will not need to sign the door.
The Delay Action mechanism is used if the door must be opened at a certain time, after which it will again be closed in the usual mode. Such devices are used in economic or utility rooms. This is especially convenient when you need to make a cargo, after a while the door again closes again and it will not be necessary to make any effort.
Each varieties of mechanisms can be installed on any door - interroom or input. When choosing the device, it is very important to take into account the width of the canvas and its weight. Adjusting the door closer requires special attention, since it will be from this that the quality of the closing will depend on this.
The principle of operation of the mechanism is that a person makes certain efforts when opening the doors that are accumulated by the built-in mechanism, after which the mechanism returns to the previous position, thereby closing the door.

Based on the design, such devices can be divided into two main groups:
- lever - construction is equipped with a crank drive;
- Censor - have a cam cam.
Types of closer mounting.
The first design option implies the presence of a spring and a hydraulic system filled with oil. Thanks to the hydraulic system, depreciation is performed. When oil leaks are detected on the mechanism, the closer is adjusted, since this is the first sign of the violation of the entire system. The valves that are located in the system adjust the flow rate of the liquid from one compartment to the other and thereby set the door closing speed.
Proper operation and adjustment of the door closer is a guarantee of its normal operation and a long expiration date. The main rule that applies to all varieties, the door must be closed itself. It is impossible to pull it or hold, trying to help close faster or slower.
If such a mechanism is installed, it should not be constantly in the open position if there is no necessary function in the instrument. If there are children in the room, it is impossible to allow them to ride on the door. Avoiding such moments, it is possible to significantly extend the use of the closer without carrying out repair work.
Main varieties of repair
One of the common breakdowns of the door closer is the leakage of the oil composition.
Closer in the context.
Despite the high tightness of the container in which the spring and oil composition are located, leaks are still possible. Most often, such a breakdown occurs in winter. If the oil composition follows, the operation of the mechanism will deteriorate, as a result, the door will be closed sharply and noisy.
When the first signs of leakage appears, it is worth considering the device and perform damage sealing. It is almost impossible to completely eliminate the breakdown, but with proper execution of the work, you can extend the service life of the closer. If the place of leakage of the oil is significant, then the repair will not be possible, you will have to buy a new device.

The second breakdown, which can meet in the mechanism, is a violation of the lever node. This element of the design is in an open place, so it is not difficult to estimate the breakdown. If the door with strength to close or hang severity on it, you can provoke the bends and the mechanism.
If the rod is damaged slightly, it is possible to correct the position with a conventional welding machine. In the event that it was broken fastening, it will take the purchase of a new original element. You need to buy only the original, because only he can come in shape, size and fastener method.
Adjusting the closer alone
Adjusting the closer can be performed independently. In order to accomplish this repair, it is worth preparing tools that will be needed in the process.
- hex keys;
- spanners;
- screwdrivers;
- pliers.
Adjustable mechanism is necessary to start examining externally. Inspection is also necessary to carry out the entire door design, namely, pay attention to the skews. Such a phenomenon may interfere with the normal functioning of the door closer.
Repair of serious damage to the device is not possible, since such a mechanism does not imply a parsing to separate details and subsequent assembly. This is due to the fact that after a sealing disorder it is impossible to restore it. But despite this, the adjustment of the closer can be performed if the mechanism disorders are insignificant and can be eliminated by adjustment.
The doors of offices, shops and other public institutions are subject to a constantly high level of operation, this may lead to the fact that the closer system will be broken. In order for the system to work properly, it is necessary to conduct a regular inspection and build it. Several times a year, especially for the offseason periods.
The main goal of adjustment is to change the speed of the closing. To do this, it stands with the help of a suitable tool to establish a springs compression level. For this corresponds to the first valve and the corresponding nut. The speed is regulated by the rotation of the naika and counterclockwise. Such rotations can be performed no more than two, the limitation is set by the manufacturer.

The second valve on the mechanism is responsible for the DCO, when the door leaf is in a position 10-15 ° from the door frame.
It is very important to regulate the operation of the mechanism with the arrival of winter and summer, this is associated with the oil content of the mechanism. In cold weather, it becomes more viscous and the door closes more slowly, the situation is different in the summer.
