The biggest feature of automatic swing doors is that there is no special requirement for the door body. As long as there are installation conditions, an ordinary swing door can be turned into an automatic door. High-strength hinges should be equipped, because the door opening torque exerts a large force on the hinges when the door operator is running. Automatic swing doors can be divided into two types: full electric and semi-electric. The two door machines have their own characteristics. The scope of application is different.
1. All-electric automatic casement door The structure of the all-electric automatic casement door is a power supply, a controller, a motor, a transmission part (such as a bevel gear structure), and hardware connecting the door leaf. The biggest feature of this automatic door is that the door body must be driven by the controller and the motor during the opening and closing processes. So it's the same as an automatic sliding door. The controller of the all-electric automatic swing door must be set in the microprocessor to control the movement of the door and the process of opening and closing the door. Such an all-electric automatic casement door has high machining accuracy for the transmission parts. Very suitable for parties such as operating rooms that require high noise levels. Because the controller of this door machine is a microprocessor, it will also have automatic reverse function and many other adjustable functions. In addition, this door machine also has a special push-to-open function, that is, when a person pushes the door by hand, the door will open automatically when the force of the door is pushed to a certain level, so that the door can be opened at Automatically operate the door without installing signal devices such as radar. If a zero-position controller is added to the automatic door, the door can be opened in both directions. That is, if a person wants to enter the room from outside the door, the automatic door opens to the inside, otherwise it opens to the outside. After adding various electrical safety functions such as overheating maintenance, this automatic door can be used for a long time.
2. Semi-electric automatic casement door In order to solve the problem that the fully electric automatic casement door cannot be used frequently, a semi-electric automatic casement door has occurred. That is, the door opening process is driven by a motor. Ordinary motors require a set of variable-speed transmission structures, and this structure can be equipped with a spring energy storage device. When the door is opened, the spring is tightened, and then the door is closed by the release process of the spring. This door machine is closed by a spring when the power is off, so it can be used for fire doors. Since the electrical part only operates during the door opening process, the electrical stability is doubled.
3.Electro-hydraulic automatic casement door is opened by motor but closed by hydraulic door closer. The structure and working principle is that the electric motor drives a heavy-duty hydraulic door closer through an oil pump to realize the door opening process. The door is then closed by a door closer. After the hydraulic door closer technology was very naive, the electro-hydraulic automatically opened the door. The control of the door opening and closing process through the door closer can be very complete. That makes the user feel very comfortable. The most important comparison is the semi-electric automatic casement door mentioned above. The biggest advantage of the electro-hydraulic automatic casement door is that all moving parts are in a sealed state, which completely prevents the wear caused by dust accumulation. Super heavy-duty electro-hydraulic automatic swing door driver, in addition to high-power motors and super heavy-duty door closers, the most important persistent opening state is achieved through an electromagnetic hydraulic valve of the door closer, so the length of the open circuit is maintained. And the motor does not have any effect. Electro-hydraulic automatic casement door due to its fully enclosed structural design. It is therefore a maintenance-free automatic door operator. Due to the large opening torque of the automatic hinged door, the strength requirements of the door hinges are high. It is recommended to use heavy hinges.
