How a three-wing revolving door works

The three-wing revolving door has been widely used in commercial and public places because of its simple appearance, beautiful design and economic practicability. The following is a summary of how the three-wing revolving door works based on search results:

Structural composition

The three-wing rotary door consists of three components: a fixed frame, a central shaft assembly and a rotating assembly. The fixed frame is composed of an upper support assembly and a column, an upper and lower dock and a fixed hanging plate. The center shaft assembly is the drive system of the automatic rotating door, including the deceleration motor and the drive mechanism, responsible for the opening and closing of the door. The rotating assembly is used to open and close the door.

Functional characteristics

The three-wing revolving door is designed to be energy efficient and blocks direct access between the building's interior and exterior, making it a buffer device that minimizes heat loss. In addition, the three-wing rotary door also has the advantage of good sealing performance, which can separate indoor and outdoor air and reduce the waste of indoor air conditioning energy.

Working principle

The wings of the three-wing revolving door are fixed on the central door axis in a divergent manner, and the angles between the doors are equal. When a person pushes the door between the inner doors, it becomes a manual revolving door. The central door shaft is installed above the motor and other electrical control components, coupled with induction devices and safety devices, it becomes an automatic revolving door. This kind of structure has high stability, strong reliability and long service life.

Performance limitation

Considering that the revolving door must be sealed when it stops, each division of the three-wing revolving door can accommodate more people, but the net opening width of the door is smaller. Each division of the four-wing revolving door can accommodate fewer people, but the net opening width of the door is larger. However, the fixed way of the door wing and the intermediate shaft determines that the width of the door can not be too large, and the diameter of the revolving door is only about 3.6 meters. In order to solve this problem, the designers designed the door type of the middle exhibition room, that is, the addition of the exhibition box, relatively reducing the width of the door, increasing the torque of the rotation of the motor on the door, so that the diameter of the revolving door is expanded to 5 meters, the middle exhibition room also has a good decorative effect.
