How to choose an imported electric window opener?

Imported electric window openers can automatically open and close windows. It is widely used in large sports venues, waiting rooms, department stores, hotels, hospitals, public entertainment facilities, factories, natural smoke exhaust windows, and smoke exhaust windows, usually associated with fire protection systems. Be careful when selecting and purchasing electronic switches.

1. Work environment: It is necessary to confirm the usage environment of electrical switches. When indoors, outdoors, or outdoors, the electric motor itself must have a high level of protection.

2. Work frequency: The number of times a task is repeated per unit of time. Electronic window openers are usually suitable for working in a short period of time, while ordinary electronic window openers are not very suitable for frequent window opening.

3. Working voltage: Generally, the working method is AC220V voltage. In special circumstances, the working method is DC24V voltage connected to the fire protection system, and the DC48V power supply for communication facilities.

4. Travel speed: Generally measured in millimeters per second, the speed of an electric window opener is not too high, so the average current indicator is ≤ 40 millimeters per second, and the speed cannot be adjusted.

5. Stretching stroke: directly affects the size of the window opening angle. For ordinary ventilation only, the opening angle should not exceed 30 degrees (determined by the height of the window), and the travel of windows with a height less than 1 meter is usually 300-400 mm; When the fire alarm signal is interlocked, the maximum opening angle of the window is usually 70 degrees (the larger the stroke of the chain window opening device, the smaller the driving force).

6. Push pull: Select and place window openers of different standards based on the actual situation of the user's window, which is directly related to the weight of the driven window.
