Features of electric hermetic door

Hospital operating rooms require high-performance tightness. How does the electric hermetic door achieve such airtightness? The guide wheel fits the groove of the rail, and the bottom groove of the movable door fits the small cylinder. When the movable door leaf is closed and moved to the groove, the door presses the rubber strip around with the system control and the weight of the door body. It makes the door leaf fit to the door frame and the ground, which can effectively isolate any interference airflow and dust, and can maintain the indoor air pressure level.

Because the electric hermetic door is installed in the operating rooms, hygiene must be strictly controlled. The use of automatic doors can ensure easy access without the need to touch the door body with hands, preventing clean hands from touching the bacteria on the door body.

The electric hermetic doors include single-open and double-open types. The track is made of aluminum alloy. The transmission structure is reasonable, reliable and has a long life. The door body adopts foaming technology, and the surface is decorated with stainless steel plate or aluminum material, and a variety of plastic spray colors can be selected. Sealing strips are installed on both sides and the middle seam, which meets the hygienic requirements of the hospital. Sensitive resistance detection increases safety performance. The track and door can be directly attached to the wall with a quick and easy installation.

The electric hermetic doors can be opened by a foot sensor switch, a push-button switch or a remote control switch. The automatic door opening time can be adjusted in 3-20s, which is convenient for personnel and surgical vehicles to enter and exit.

The electric hermetic doors are mainly used in hospitals and medical places, bringing great convenience to hospitals and patients. Let's talk about the basic working principle of it.

First of all, there are seven main components of an electric hermetic door unit.

  1. Main controller: It is the command center of the automatic door. It instructs the motor and the system to work through a large-scale integrated block with a built-in instruction program. People can adjust parameters such as the door opening speed and opening range through the main controller.
  2. Sensor: Receives external signals, just like people's eyes. When a moving object enters its working range, it sends a pulse signal to the main controller;
  3. Motor: Provides the main power for opening and closing the door, and controls the acceleration and deceleration of the door leaf;
  4. Hanger: Suspend the movable door leaf, and drive the door leaf to run under power traction;
  5. Track: Guides the spreader of the door leaf to make it travel in a specific direction, just like the rails of a train;

6.Belt: Transmits the power produced by the motor and to pull the door leaf spreader wheel system.

  1. Swing stopper: It is the guide and positioning device of the lower part of the door leaf, preventing the door leaf from swinging during operation.

The working process of the automatic door is as follows: When the sensor detects someone entering, it sends a pulse signal to the main controller. When the main controller receives the signal, it informs the motor to run and monitors the motor rotation speed to notify the motor to accelerate or decelerate if necessary. The motor will run forward after it gets a certain current. The power will be transmitted to the belt, and then the belt will transmit the power to the hanger to open or close the door.
