Electric door devices are often used in commercial and public buildings. This is a mechanism that automatically closes the door leaf through an electronically controlled method. It is a high-grade wooden door hardware accessory. So what are the ways
to install the electric door closer ? Let's get to know it soon.
[What is electric door closer]
Electric door closers can also be called automatic door closers or they can also be called electric releasers. This is a machine that uses an electronically controlled method to automatically close the door. The difference between the electric door closer and the hydraulic fire door closer is that the releaser and the non-positioning system are combined into one. Through the internal solenoid valve and the strong spring to push the door, the compression spring causes the door leaf to lock. This type of East Door Closer was first used in the normally open fire door. After a series of inspections by the fire department, the door was found to be closed. The use of current, some dangerous situations, so in the current fire door market is still using the old hydraulic automatic door closers, which can effectively prevent the occurrence of dangerous situations.

The electric door closer consists of two parts: the electric door closer body and the guide slot. The main body of the electric door closer is installed at the door frame, and the guide slot is installed at the door leaf. The electric door closer is mainly composed of shells, arms, guide rails, electromagnets, springs, ratchets and other components, and its composition is more complicated. There are more than 60 kinds of small parts and components, and some parts are more important. If the quality of these parts is not enough, it is very easy to cause the electric door closers to fall apart.
[Installation method of electric door closer]
1. The most common standard usage is to install the door closer to the side of the hinge and open the door. When so mounted, the arm of the door closer protrudes outward, about 90° from the door frame.
2. The door closer is mounted on the opposite side of the hinge side and the door is closed. Typically an additional bracket provided with the door closer is mounted to the arm parallel to the door frame. This usage is usually on an outside door that is unwilling to install the door closer outside the building.
3. The door closer body is in turn mounted to the door frame rather than the door. The door closer is on the opposite side of the door hinge. This usage can also be used for exterior doors that open outwards, especially with only a narrow upper edge, without enough space to accommodate the doors of the door closer body.
4, vertical door closers (built-in vertical door closers) upright hidden in the side of the door hinge side, from the outside can not see the screws and components, can be made with the door, can be a single two-way opening and closing, the construction is simple.
[Use of electric door closers] 1. The electric door closer products must meet the national standard GB9305-88, and the door closers used for fire door applications should also meet the requirements of GA93-1995 Fire Door Closer Test.
2. The factors that should be taken into consideration when selecting the door closer are: the weight of the door, the width of the door, the frequency of opening the door, the use requirements and the use environment.
3. The weight of the door and the width of the door are the most important factors in selecting the type of the door closer. Common doors include fire doors, wooden doors, aluminum alloy doors, glass doors, and steel doors. Usually, the weight of the door is small, so the model with the smaller power is selected, and vice versa.
4. The door opening frequency is a factor closely related to product quality. For frequently used occasions, products with good sealing performance and long life are to be selected.
