Imported electric window opener can automatically open and close windows. It is widely used in large gymnasiums, waiting rooms, department stores, hotels, hospitals, public entertainment facilities, factories, natural smoke exhaust windows and smoke outlet windows, which are usually associated with fire protection systems. Care must be taken when selecting and purchasing electronic switches.
1. Working environment: the operating environment of the electrical switch must be confirmed. When indoors, outdoors or outdoors, the motor itself must have a higher protection level.
2. Working frequency: the number of repeated operations per unit time. Electronic window opener is usually suitable for working in a short time, while ordinary electronic window opener is not suitable for frequent window opening.
3. Working voltage: generally AC220V voltage working method, DC24V voltage working method connected with fire protection system under special circumstances, DC48V power supply of communication facilities.
4. Travel speed: generally in mm / s, the speed of electric window opener will not be too large, so the average current index is ≤ 40mm / s, and the general speed cannot be adjusted.
5. Stretching stroke: directly affects the opening angle of the window. For general ventilation only, the opening angle shall not be greater than 30 degrees (the opening angle is determined by the height of the window), and the stroke of the window with a height of less than 1m is usually 300-400 mm; When the fire alarm signal is interlocked, the maximum opening angle of the window is usually 70 degrees (the greater the travel of the chain window opening device, the smaller the driving force).
6. Push and pull: select and place window openers of different standards according to the actual situation of the user's window, which is directly related to the weight of the driven window.
